Introduction Introduction / Components The Tri-Tech Medical gas alarm system monitors the status of the medical gas distribution system and provides audible and visual indicators. The alarm panel can be interfaced with a Tri-Tech Medical MCP100-A or ACP-100-A Building Management interface panel for remote monitoring of the entire facility. The Tri-Tech Medical gas alarm system is a two or three section assembly comprised of a rough-in box, a front panel and transducers (only if it is an area alarm or combination alarm). Rough-in box The rough-in box houses the power supply, fuse, on/off switch, and a terminal strip for electrical wiring. An isolated transformer reduces the 110V or 220V AC input to low voltage DC. Front panel The front panel includes enclosed printed circuit boards with programming circuitry. The CPU module includes a power on indicator, programming buttons, an audible alarm, and an LED status display. The Remote Signal module(s) can monitor up to 16 signals per circuit board. Multiple remote signal modules can be ordered in a single alarm. The signals can be configured to display an abnormal condition on either a normally closed (NC) or a normally open (NO) circuit. Each signal may also be turned off if it is not being utilized. The Gas (Area) module(s) on the front panel are identified with gas specific, color coded labels (per NFPA 99 or CSA Z305.1). The gas displays include LED s which indicate high/normal/low pipeline pressure. A digital LED display shows the actual gas pressure. The gas pressure may be displayed in PSI and Hg, or BAR or kpa. The unit is pre-programmed to display PSI / Hg from the factory, but may be re-programmed in the field to display BAR or kpa. Transducers The transducer converts pressure to an electrical signal and supplies the electrical signal to the front panel. After the initial 24 hour 150 psi standing pressure test (required per NFPA 99) has been completed the pressure/vacuum transducers are mounted in the rough-in box. The transducers may be remotely attached to the piping system at distances no further than 100 feet using Beldon 8777 shielded cable. Tri-Tech Medical recommends mounting the transducers in the alarm back box not remotely. Should a transducer require service or replacement is considerably more time consuming to locate and replace or service remotely located transducers Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-7 -

Alarm Displays & Functions Alarm Displays & Functions CPU Module Power on Indicator The power on indicator (green LED) is illuminated whenever electrical power (120 or 240 VAC) is connected to the alarm. Test Button When the Test button on the front panel is pressed, the alarm undergoes a self-test checking the lights and displaying the gas settings. If errors are detected, they are displayed on the status LED and/or on the area module gas LED displays. Status Display The status LED displays system alert codes when a problem occurs (these are numeric). See System Alert Codes on page 34 for details. The status LED also displays a P whenever the alarm is in the program mode. Alarm Silence In the event of an alarm condition an audible alarm sounds. The audible alarm can be silenced by pressing the alarm silence button. Whenever there is an alarm condition and the alarm has been silenced, the Alarm Silence Indicator LED will be illuminated. The high or low pressure LED or the remote signal LED will remain illuminated until the alarm condition is rectified. Program Mode Indicator The Program Mode Indicator LED is only illuminated when the alarm has been placed in the program mode (see Programming the Alarm page 25). It should be noted that when this LED is illuminated and the alarm is in the program mode, it is not monitoring or reporting alarm conditions for the medical gas systems. History Button The History button may be pressed and held at any time to view alarm history. Viewing alarm history is only active when the History button is depressed, releasing the button returns the alarm to normal operation. When depressed H will be displayed in the Status Display LED. Gas(Area) Module - If there was an alarm condition for any gas (area) module, the High and/or Low Pressure LEDs will be illuminated. If both the High and Low Pressure LEDs are illuminated, the gas has had both a High and Low alarm. Remote Signal (Master) Module If there was an alarm condition for any Remote Signal the Red LED will be illuminated. All other LED s will be off. Clear Alarm History To clear alarm History you simply press the History button, hold it down and press Silence button (while the history button is still depressed.

Alarm Displays & Functions Gas Displays (Area Module) Pressure Reading Display The LED pressure reading displays the pressure as indicated by the transducer. Whichever of the PSI or BAR or kpa lights is illuminated reveals the unit of measure displayed on the LED pressure reading. The Nitrogen gas display indicates one tenth of the actual pressure when displayed using kpa units (i.e. 1100 kpa is displayed as 110 and the kpa x 10 LED is illuminated). High / Normal / Low Status Lights In addition to digitally displaying the pressure of a gas, the pressure is displayed by a series of green, yellow & red LEDs reflecting the pressure as either normal, high or low. These indications are relative to the high and low pressure set points which have been programmed into the alarm. These high and low set points should be set in accordance with NFPA 99 and CSA Z305.1 at ± 20% of the normal operating pressure. As the pressure climbs above normal line pressure to 20% above normal line pressure, the LED s on the upper side of normal will illuminate, then the uppermost normal & yellow High LED s will illuminate, finally the two red High LED s will illuminate. Simultaneously with the Red LED s illuminating, the audible alarm will sound. As the pressure falls to below normal line pressure to 20% below normal line pressure, the LED s on the lower side of normal will illuminate, then the lowermost normal & yellow low LED s will illuminate, finally the two red Low LED s will illuminate. Simultaneously with the Red LED s illuminating, the audible alarm will sound. Units Button & PSI / BAR / Kpa LED s By placing the alarm in the program mode (see Programming the Alarm page 25 ) the units button toggles the LED pressure readings on the gas displays between PSI (inches Hg for vacuum & evacuation BAR / kpa LEDs. The corresponding PSI, BAR or kpa LED is illuminate indicating which units are being displayed on the gas display. Note: Vacuum & evacuation are actually displayed as inches Hg in the PSI mode. The Nitrogen gas display indicates one tenth of the actual pressure when displayed using kpa units (i.e. 1100 kpa is displayed as 110 and the kpa x 10 LED is lit. The power on LED is illuminated whenever electrical power is connected to the alarm. Note Alarm settings are maintained even if power is interrupted. Remote Signal Status LED s (Master Module) Normal Status Light (Green) The normal green status light when illuminated signifies that the equipment being monitored is not in an alarm condition. A flashing green light indicates a normal condition, but a transient (see glossary of terms for definition) signal from source equipment has been detected. Abnormal Status Light (Red) The abnormal status light when illuminated signifies that the equipment being monitored is in an alarm condition. Note: If no LED is illuminated the remote signal status LEDs have probably been set in the unused or off position. This can be verified by having the alarm run a self-diagnostic check. Simply press the Test button. As the alarm runs thru the test cycle, observe the Status Display LED when the Remote Signal in question is blinking. A d displayed on the Status Display LED indicates that the Remote Signal has been disabled. Remote Signal Description Label The remote signal description label identifies the equipment that is being monitored on the normal and abnormal LED s to the left and right of the label.

Alarm Operation Alarm Operation Refer to the Alarm Installation section for the procedure necessary to install the alarm. The Programming The Alarm section covers the procedures to follow in order to configure the alarm if the preprogrammed settings are not appropriate. After installation has been completed and the alarm has been properly configured, it is ready for operation. Remote Signal (Master) Module With electrical power applied to the alarm, the system will monitor the status of the medical gas distribution system. The remote signals (master) module displays (via LED indicators) the normal/abnormal status of the remote equipment connected to the alarm. In normal operation all active signals will be green. Whenever an abnormal status signal is detected the corresponding green LED will be extinguished and the red LED will light. Simultaneously an audible alarm will sound. Pressing the Silence button silences the audible alarm (the Red LED continues to be lit). The appropriate personnel should be notified immediately of the alarm condition. When the alarm condition has been rectified the Red LED is automatically extinguished and the Green LED illuminates. Whenever an intermittent Transient (see Glossary of Terms for definition) abnormal status signal is detected from remote equipment by the alarm, the Green or Red LED will start to flash. Transient alarms indicate a potential problem. The appropriate personnel should be notified of the alarm condition. Pressing the Test or Repeater button returns the flashing LED to normal operation. Note The Remote Signal (Master) alarm is set to Ignore transient signals that are less than 0.6 seconds in duration. Gas Modules With the electrical power applied to the alarm and the gas systems adequately pressurized, the following indicators are illuminated: 1) the Power On LED, 2) the pressure readings of the gas on each gas display, 3) the Normal LED (green) on each gas display. If the pressure of one of the gases drops below the low limit setting, the following events take place simultaneously: 1) the Normal LED will be extinguished, 2) the Pressure Low LED (red) will light up, 3) an audible alarm will sound. If the pressure of one of the gases rises above the high limit setting, the following events take place simultaneously: 1) the Normal LED will be extinguished, 2) the Pressure High LED (red) will light up, 3) an audible alarm will sound. Silencing the Alarm Press the Silence button when the alarm is sounding and the alarm will be silenced. This alarm is equipped with a Repeater Delay feature which monitors only the Gas Module (Area) alarms. The Repeater Delay has been factory programmed to make the alarm re-sound every 11 (eleven) minutes as long as the alarm condition exists. (Note: Remote Signal (Master) alarms are not monitored by the Repeater Delay). Pressing the Test button initiates a self-test of the alarm. Each LED will illuminate in succession for 2.5 seconds. The displays are then cleared and the system circuitry is checked for proper voltages. If no errors are found, the alarm returns to normal operation. If an error is found, the error is indicated on the Status Code Display. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-13 -
Alarm Operation Testing the Alarm Pressing the Test button initiates a self-test of the alarm, resets any system status alerts that may be active and re-initiates the alarm-repeat function. Pressing any key will abort the test displays but not the internal tests. The test commences in the following order: 1. The alarm will sound, the status display will display 8 and the 1 st active module will be displayed with all lights illuminated for 2.5 seconds. This is the only time the alarm will sound and the Program & Silence LED indicators will illuminate during the test. 2. Each remaining active module will be displayed with all lights illuminated for 2.5 seconds, in sequence. The Gas (Area) Modules will be displayed first (if gas modules exist). The Remote Signal (Master) Modules will be displayed second (if Remote Signal modules exist). Each existing active module will be displayed for 2.5 seconds. 3. After all existing modules have completed the lamp verify test above, any existing Gas (Area) Module set points will be displayed for 2.5 seconds. If no Gas Modules exist, these displays will be bypassed. All the high set points will be displayed for 2.5 seconds first with the high alarm LEDs indicating which set point you are observing. Any Master modules that exist will not be illuminated during this time. If a gas is not active, i.e. the module exists but an inactive shunt instead of a transducer is connected to the gas, the gas display will be blanked. 4. Next the active Master modules will be displayed, one at a time, displaying the current alarm programming and the contact state of each alarm point. Each of the Master module displays will consist of the following: The module will be illuminated. The top parameter will be flashing indicating it is the first alarm point under test (the active alarm point). The status display will display the current contact state of the active alarm point. This display will consist of: C = closed, O = open, d = disabled. If the active alarm point is disabled, both alarm point LED s (both the green & the red) will be illuminated. This is only for the test display. In normal operation, both of the LED s will be turned off. After 2.5 seconds, the next lower alarm point will flash and the status display will show it s contact state for 2.5 seconds. This sequence will continue until the last (bottom) alarm point has been displayed. This action will continue until all active Master module alarm points have been displayed. 5. When all active modules have been displayed (Gas and/or Master), the test will be complete and the system will return to normal operation. Remember, you can exit the test at any time by pressing any key. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-14 -
Alarm Installation Alarm Installation Installation of the Tri-Tech Medical alarm involves installing the rough-in box, the transducers (if it is an area alarm or combination alarm) and front panel and making the necessary conduit, plumbing and electrical connections. All installation and testing should be done in accordance with NFPA 99 or CSA Z305.1. WARNING: All electrical power should be disconnected prior to installation. WARNING: This device should only be installed by qualified personnel. Installation should not be attempted by anyone not having general experience with the installation of devices of this nature. Rough-In Box Installation This is a rough-in box for a combination alarm. Your rough-in box should look the same or similar to this unit. Refer to the building plans to determine the location of the alarm. The contractor is to provide rigid mounting that will support the alarm box on both sides. The metal flanges provided on both sides of the rough-in box are to rest against the rigid mounting brackets. Screws (contractor provided) are to be driven thru the holes in the metal flanges into the mounting brackets. Mount alarm rough-in box so it will be flush or just below the finished wall surface using the adjustment feature on the flanges. (Side/end view of rough-in back box) Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-15 -
Alarm Installation The power supply hole is located in the bottom (left side) of the rough-in box. Remove the plaster cover and panel covering the power supply. Remove the plug from the hole. Make conduit connections for wiring from the facility emergency power source. To remove the power supply cover, loosen the two screws at the top of the cover and slide the cover to the right, then lift the cover over the screw heads. Slide the wiring harness strain relief to the left until it is free from the cover. Wiring Use the ½ conduit knock-out provided on the bottom left side of the rough-in box to route conduit to supply either 110 or 220 V AC to the power supply. Note: Separate conduit should be used for low voltage wires (use knock outs provided on the top of the box). Neutral Hot Field Ground Route wires through the power supply conduit installed in the bottom and left side of the roughin box. Connect the 110 or 220V AC facility emergency power source electrical wiring to the terminal strip provided on the lower left side of the box. (N = neutral, H = hot, FG = field ground) Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-16 -
Alarm Installation The wiring harness will be provided pre-wired to the power supply. If by chance it is not prewired, the single green ground wire should be fastened to the screw on the top left corner of the power supply board. The wiring plug in connector (which should contain the rest of the wires), plugs into the connector terminal on the upper left corner of the power supply board. The black wire will be on the top. This is how the power supply should look when the wiring is completed. Replace the power supply cover and plaster cover (to protect the unit while the drywall and wall covering work are being done) after wiring is complete Plumbing the Riser Extension Tubes Riser extension tubes After removing the protective plastic caps, connect the riser extension tubes (only included if this is an area or combination alarm) to the gas piping system. Make sure drop is for the proper gas service. Using a purge gas to insure cleanliness in the tubes, silver braze the joints. Do not use soft solder. Conduct heat away from the check valves. (A purge kit is required for purge equipment connection to the system). The 150 psi standing pressure test of the piping system must be successfully completed and all pressure removed from the system before connecting the transducers to the system. Attaching transducers without depleting the 150 psi standing pressure first will result in damage to the transducers! Note: It is recommended that gas piping system tubing be connected from the extension tube to the ceiling for a future or blank gas display even though a transducer is not being installed. Cap the unused tube at the ceiling. This will simplify future expansion. Note: It is also possible to install the transducers remotely (not in the alarm box). In this type of installation the riser extension tubes should be removed from the alarm back box and connected to gas piping system at a distance not to exceed 100 feet (wiring harness length) from the alarm back box. Belden 8777shielded cable is required. Note: Tri-Tech Medical recommends mounting the transducers in the alarm back box not remotely. Should a transducer require service or replacement is considerably more time consuming to locate and replace or service remotely located transducers.

Attach the plug connector at the end of the wiring harness to the appropriate connector located at the top left corner of the CPU circuit board. The plug should lock into place. The plug can only be inserted one way. This is how the wiring harness plug connector should look when properly installed on the back of the CPU board. Installing the Transducers After depressurizing the 150 psi standing pressure from the piping system, install the appropriate transducers to the appropriate riser extension tube connectors inside the rough-in box. Hand tighten then torque lightly with a wrench. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-19 -
Alarm Installation Connecting the Transducer Wiring to the Alarm Front Circuit Board Insert the plug(s) from the transducer(s) to the appropriate connector(s) on the back of the gas module circuit board(s). The plug on the transducer and the panel connector are both labeled by gas symbol at the factory for proper installation. The plug can only be inserted one way. Visually verify that the appropriate transducer plug is being attached to the appropriate gas module by looking at the front of the alarm panel. The transducer plug will look like this when it is connected properly to the gas module. Insert the transducer cable underneath the cable clip as shown using the clips provided. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-20 -
Alarm Installation Wiring the Remote Devices to the Remote Signal (Master) Board Locate the two banks of 16 terminal connectors on the back of the remote signal (master) board. There are a total of 32 connection points two connection points for each remote signal. The pairs are labeled P1 thru P16 on the circuit board. The top terminal of each pair is where the signal wire should be landed. Remote signal #1 signal wire Remote signal #1 common wire Remote signal #2 signal wire Remote signal #2 common wire There are two options for landing the common wire(s). Option #1 you can land the corresponding common wire on the bottom terminal of each pair of terminal connectors. This option is recommended for maximum interference suppression. Option #2 you can connect all of the common wires together and land just one common wire on the bottom terminal of P16. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-21 -
Alarm Installation Labeling the Alarm Front After all remote signal (master) wires have been landed, identified & cataloged (using appendix C in this manual), you are ready to apply the remote signal labels. Remove by unthreading the two nylon nuts shown here from the back of the alarm front panel. The panel will now lift out of the black frame. Provided in the packaging with the alarm front panel is a long white card and a pre-printed sheet of labels for the remote alarm signals. Wash your hands before handling these labels and cards! Apply the labels to the appropriate position on the card using the guide lines on the card. When complete, insert the card into the Monitored Signals label pocket - between the stainless steel plate and the front of the Monitored Signals label. The gas modules are shipped pre-labeled from the factory. If a gas service is changed to a different gas or added to the alarm, it will be necessary to insert the appropriate label in the pocket of the gas module. The new gas label supplied by Tri- Tech Medical will slide into the gas module label pocket between the stainless steel plate and the front of the gas module label. When the labeling is completed, install the stainless plate into the black frame and re-attach with the two nylon nuts. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-22 -

With the high or low set point pressure displayed, press either the UP key (Test button) or the DOWN key (Silence button) to change the set point to the desired pressure. When high and low set points have been changed to the desired settings, you must press the Program button twice to save the changes and return the alarm to the normal monitoring mode. Note: The alarm is designed with a safety feature so that the high and low set points must be at least 2 to 5 increments (psi, bar, kpa, in Hg) apart. The high set point will not be able to be set below the low set point and visa versa. Note: Depressing the UP or DOWN keys will accelerate the rate of change up to 12 increments per second. Note: An abbreviated name of the gas service will be one of the displayed items along with the high and low pressure alarm set points. The full names of the gases and their corresponding abbreviations are per the chart below: n2 = nitrogen o2 = oxygen n20 = nitrous oxide Co2 = carbon dioxide UAC = vacuum EUA = evacuation Air = medical air hpa = high pressure air hpo = hyperbaric oxygen hpc = high pressure carbon dioxide gas = gas mixture Err = error Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-25 -
Programming the Alarm Note: If Err should be displayed on the Gas Pressure Display of any gas module, this indicates a problem. Some possible problems and corrective actions are: The transducer is not connected to the Gas Module. To correct, check the transducer connection to the back side of the Gas Module. A transducer for a different gas service has been connected to the Gas Module. To correct, check the transducer and the Gas Module gas identification labels and make sure they match. If the above corrective actions do not correct the problem, contact the factory for assistance. Programming the Remote Signal (Master) Alarm Points While in the program mode, press the Module button until the desired Remote Signal (Master) Module is illuminated. It s LED will display the current programming for the contact state that defines a normal condition. With the desired Remote Signal (Master) Module flashing, press the UP or DOWN key to view the next Remote Signal Alarm Point. All contacts are programmed as closed contact equals a normal condition from the factory. The contact point that is flashing is capable of being programmed. The Status Code Display will display the current state for the contact point that is flashing. The Status Code Display will read either: O for open or C for closed or d for disabled Note: Any contact point that has been disabled will have both the green (normal) and red (alarm) LED illuminated only when in the programming mode, to make it easy to identify them. In the normal mode of operation, both LED s of a disabled parameter will be blanked (off). With the desired contact point flashing, press the TOGGLE key (history button) to change the state of the selected contact point. The sequence of the TOGGLE key is as follows: Closed = normal Open = normal Disabled Each individual contact point may be programmed to any of the three (open, closed or disabled) states. Using the UP or DOWN keys you can go on to the next contact point. When programming of all of the contact points is complete press the Program button twice to save the changes and return the alarm to the normal mode. Programming the Gas Alarm Repeater Delay While in the program mode, press the Alarm button. A number (0 7) will be displayed on the Status Code Display. The first gas display will display A-r which is an abbreviation for Alarm Repeat. All other modules will no longer be illuminated. If a 0 is displayed on the Status Code Display, this means that the Alarm Repeat feature has been disabled. (This setting is ideal during the construction phase of a project). (Note disabling or enabling the Repeater will not change the delay setting). To enable this feature press the TOGGLE key (History button) until a number 1 7 is displayed on the Status Code Display. When the Alarm Repeat feature has been enabled, the UP or DOWN keys may be used to change the setting. The chart below represents the approximate length of silence time before the silenced alarm will repeat: 1 = 5 minutes 2 = 10 minutes 3 = 15 minutes 4 = 30 minutes 5 = 1 hour 6 = 2 hours 7 = 4 hours The alarm will be pre-programmed from the factory at ten minutes. This is the recommended setting. To save the change and return the alarm to the normal mode, press the Program button twice. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-26 -
Programming the Alarm Programming the Units of Measure Displays While in the program mode, press the Units button. (This key is only active if a Gas Module exists in the alarm.) The Status Code Display will display a U and the first Gas Module will display E-U on the Gas Pressure Display. The Units of Measure Indicators will display the selected engineering units. The High / Low Pressure LED s will be off. All other module displays will be off. Use the TOGGLE key to switch between engineering units PSI, BAR or kpa. When you have selected the engineering units that you would like for the pressure display, press the Program button twice to save the change and return the alarm to the normal mode. Note: All Gas Modules will display pressure in the same units as selected. Note: Vacuum & Evacuation Gas Modules will automatically display in in/hg when PSI is selected. Note: The kpa and x10 LED s will both illuminate on all high delivery pressure Gas Modules (i.e. Nitrogen and Hyperbaric Oxygen) when kpa is selected. Because the Gas Pressure LED Display is only able to display three digits and high delivery pressures viewed in kpa are four digits, the Gas Pressure LED must be read as a four digit number by multiplying the displayed number by ten. I.E. the Gas Pressure LED Display is displaying 125 in kpa. The pressure should be read as 1,250 kpa (125 x 10). Programming the Zone Identification # Note: This feature is only used when a Tri-Tech Medical ACP-100 Building Management Interface Panel is added to the alarm system. Note: Each alarm must have a unique Zone Identification Number no two can share the same number. While in the program mode, press the I.D. button. The Zone Identification Number will be displayed on the Status Code Display. If a Gas Module is present in the alarm, Id will be displayed on the Gas Pressure LED Display. Valid identification numbers are 1 29. As the Status Code Display is only a single character display, it will flash the current Zone Identification Number. I.E. let s assume the current Zone Identification Number is 16, the Status Code Display will flash: Blank, Blank, 1, Blank 6, Blank, Blank, 1, Blank, 6, etc. Use the UP and DOWN keys to change the Zone Identification Number. Press the Program button twice to save the Zone Identification Number selected and return to the normal mode. Note: Valid identification numbers are 1 29. The alarm is pre-programmed at the factory with 0 (zero) as the zone identification number. 0 (zero) should be used whenever there is not a Tri-Tech Medical ACP-100 Building Management Interface Panel installed in the alarm system.

Adding or Deleting Modules Adding or Deleting Modules This section covers the procedure for adding or deleting a module to the alarm. This section also covers the procedure for removing an active Gas Module from service or placing a currently inactive gas module into service. Note: Before attempting any wiring or electrical component changes, the power to the alarm must be turned off! Failure to turn the power off the alarm during wiring or electrical component changes may result in damaged or destroyed components. Use the ON/OFF switch that has been provided in the lower left hand corner of the rough-in or back box. Adding / Removing a Remote Signal (Master) Module In order to add a Remote Signal (Master) Module, the alarm must have a future expansion position (as shown on right of photo) available. The first step will be to remove the future expansion label and replace it with a remote signal label. Open the alarm front by pulling the top of the front panel away from the wall. Next, remove the front panel from the front frame by unthreading the two nylon nuts shown here from the back of the alarm front panel. The panel will then lift out of the frame. Set the panel upright with its bottom resting on the frame. Tri-Tech, 810 Center Road, Bldg.-E, Avon, Ohio 44011-28 -
Adding or Deleting Modules Peel off the existing future expansion label and remove any remaining adhesive with rubbing alcohol. After the surface is clean and dry, install the remote signal label. Match up the holes on the top and bottom of the label with the holes on the plate for proper alignment. Provided in the packaging with the alarm front panel is a long white card and a pre-printed sheet of labels for the remote alarm signals. Wash your hands before handling these labels and cards! Apply the labels to the appropriate position on the card using the guidelines on the card. When complete, insert the card into the Monitored Signals label pocket - between the stainless steel plate and the front of the Monitored Signals label. Reinstall the front panel into the front frame. Attach the remote signal circuit board to the alarm plate using the screws and stand-off s provided. Attach the short ribbon cable to the open position on the bottom of the neighboring circuit board and the other end of the short ribbon cable to the innermost receptacle on the newly added remote circuit board. This will leave the outermost receptacle vacant on the new circuit board. Note: The male connector on the ribbon cable will only connect one way to the receptacle. Remove the existing ribbon cable running across the top of the circuit boards. Install the new longer ribbon cable provided to connect all of the circuit boards. Note: The male connector on the ribbon cable will only connect one way to the receptacle. Note: The top and bottom ribbon cable male connectors and female receptacles are not interchangeable.
