3.2.1 Bell Circuits The NZ400 provides a monitored bell circuit split to drive two x 2Amp circuits. When monitoring is enabled these circuits each require a 10K EOL resistor to give a system normal indication. If either circuit is open or shorted, a defect signal is generated and the BELL defect LED is illuminated. See section 4 for connection details. 3.2.2 Bell Isolate (Internal) This facility allows the fire alarm system to be tested without disturbing the building occupants. The bells are isolated and returned to normal state by alternate pushes of the Bell Isolate switch. The yellow LED above the internal bell isolate switch indicates when the bell is isolated. This switch is monitored. See section 3.2.5. 3.2.3 Walk Test This function is initiated by a single press of the TEST button. The LED indicator WALK above the TEST button indicates when the system is in walk test. While the system is in the walk test mode the detectors can be operated in the field and the system will sound the bells for 3 seconds and then reset. To restore the system to normal operation, press the switch again and the walk test indicator will turn off. This switch is monitored, See section 3.2.5. Note that pressing the TEST switch again quickly (within two seconds of the first press) will activate the self-test function. If this occurs press the switch again to return to normal. 3.2.4 Self Test The self-test is activated with a double press of the TEST button. The LED indicator SELF above the TEST button indicates that the system is in self-test. The self-test function will sequentially test each zone by placing it into alarm and defect. On completion of the self-test the system will automatically return to its normal mode of operation. This test may be terminated at any time by pressing the TEST button again. This function will inhibit brigade calls and sounding the bells during the test. 3.2.5 Door Interlock The door interlock prevents system controls from being inadvertently left in an off normal position with the outer door closed. If any of the monitored switches either on the NZ400 or connected Signal Generating Device are not in their normal state when the door is closed, the buzzer will sound to alert the operator. The following switches are monitored: NZ400 - Walk Test and Internal Bell Isolate, SGD Test and Isolate. If the Walk Test or Internal Bell Isolate is active when the door is closed, they automatically return to their normal state after ten (10) minutes. 3.2.6 Defect Indicators Indicators are provided for the following defects. (a) Battery Fault. This indicates if the battery voltage is below 12.1 volts, or the battery is disconnected or the battery has failed the discharge test. (b) Bell Fault. This indicates an open or short circuit on bell line/s. (c) System Fault. This indicates one of the five following fault conditions. When a fault has occurred, the numeric display will indicate the condition. If more than one system fault condition exists only the fault with the lowest number will be displayed Processor failed internal check sum check. EEPROM damaged or corrupt. DBA circuit fault Power converter for detectors failed. Earth fault Mains power has failed. Page 5

3.2.7 DBA Input An input connection is provided for connecting to an external device that has a Direct Brigade Alarm (DBA) output, e.g. sprinkler systems. A short circuit on this line will cause the DBA LED to light and the system bells to be energized. This input is monitored for normal condition with a 10K resistor. An open circuit will cause a DEFECT status. 3.2.8 Power Supply The system has an on board linear power supply providing 13.5V DC at 0.5A for system power and charging the battery. The system incorporates two test functions, controlled by the CPU. The first test is performed every sixteen seconds and checks to see whether the battery is connected. The second test decreases the power supply output voltage for forty-five minutes, every forty-eight hours to check the condition of the system battery. If the battery voltage falls below 12.1V during either test, a defect signal is generated and the battery fault LED is illuminated. The defect will only be reset on a successful battery condition test or by operation of the RESET. 3.2.9 Mains On Indicator This LED is illuminated when the mains supply is connected and operational. 3.2.10 Fusing The NZ400 main board has five (5) fuses: F1 External 0.8A F2 Battery fuse 0.8A F3 AC input fuse 0.8A F4 Bell 1 Fuse 2 A F5 Bell 2 Fuse 2 A 3.2.11 Zone circuits All four detector circuits can accept smoke detectors, heat detectors, manual call points or nonlatching inputs e.g. flow switches. Detectors or manual call point types used are subject to the compatibility limitations as described in section 4. Open circuit operating devices will cause the system to go into alarm within one second. Devices such as smoke detectors, which signal by increasing line current, can, when signalling, go through an Alarm Verification Facility (AVF). As such, when a detector goes into alarm, it is reset and not monitored for seven to eight seconds, if an alarm is still present after this time, the system will latch into alarm. The AVF function may be disabled if desired. See section 6 for details on setting options. When the zone is configured for a flow switch (non-latching) the system will respond to an increase in detector zone current. To signal an alarm condition a resistor in the range of 220Ω to 560Ω should be wired in series with the contacts. 3.3 Batteries The NZ400 system is designed to accept one x 12V, 7 AH sealed lead acid battery. Page 6

4.0 CONNECTING DEVICES 4.1 Detectors The alarm circuits can use devices such as heat detectors or manual call points which are normally closed, open circuiting for the alarm condition or devices that increase the current in the detector line such as smoke detectors or a combination of both. See also section 3.2.11 for description of operation. L1 OUT L2 L1 IN Z1 - EOL RESISTOR 6.8K HEAT DETECTOR OPENING ON ALARM MANUAL CALL POINT 560 Ohm Resistor BEAM DETECTOR OR NON LATCHING INPUT CONTACTS SMOKE DETECTOR (eg APOLLO SERIES 60 DETECTOR) THIS DRAWING IS INDICATIVE OF WIRING ONLY. ANY COMBINATION OF DETECTORS AND MANUAL CALL POINTS WITHIN SPECIFIED LIMITS IS PERMISSABLE. Note: Detectors must not directly short the line as a short circuit gives a defect signal. Devices that have closing contact outputs, such as beam detectors, should have a resistor, in the range of 220 to 560Ω installed in series with the contacts. Each circuit must be terminated with an end of line resistor with a value of 6.8K (5% tolerance or better, power rating 1/4W) 4.1.1 Detector Limitations Most detectors, with the exception of thermostatic heat detectors, draw a small monitoring current and this imposes a limit to the number of detectors which can be connected to a given zone circuit. The total quiescent current of all devices on a zone circuit must be less than 1.6mA @ 24V to ensure correct operation. Appendix A lists the number of detector types which may be fitted to a zone circuit. Page 7

4.2 Bells and Sounders *EOL S B 1N4004 DIODES BELLS B BELL O/P 1-1ST CIRCUIT *EOL 1N4004 DIODES S B BELLS B 2ND CIRCUIT ON BELL OUTPUT 1 (OPTIONAL) Two bell/sounder circuits are provided, capable of driving a combined load of 3.75 Amp (0.25 A is reserved for the system-operated light). These lines are monitored using a small current in reverse polarity to normal. For this reason it is necessary to connect the bells via diodes, 1N4004 diodes are recommended, as shown in the following diagram. Also observe bell/sounder polarity. If required these lines can be split to provide three or four bell circuits total, as shown, however if this is done the end of line resistor must be changed. See table 4.2 for further detail.

This can be useful during periods of building maintenance or to allow monitoring of the mains condition without a power failure causing a defect signal to the brigade. Unlike the previous options the options in this case relate to the defects as indicated on the left of the LED s. 6.2 Displaying the Current Options To display the options from the normal state, press the OPTION key. The OPTIONS LED will illuminate to indicate that the options are being displayed. Press the NEXT key to step through each group of options. See option settings for a complete listing of available options. To cancel the display press SELECT or RESET. Display will automatically terminate thirty seconds after the last key press. Page 11

6.3 Changing the Options 6.3.1 Entering Programming Mode Before any changes to the configuration of the system can be made, it is necessary to put the system into program mode. To change the configuration first press the SELECT then the OPTION keys. The numeric display will illuminate. It is now necessary to enter the pass code. (The pass code is 411) To enter the pass code press the NEXT key until the correct number (4) is displayed, then press the 'SELECT' key. Repeat this sequence until entire code (1), (1) has been entered. An incorrect entry will cause the sounder to sound a long beep and the display to cancel. After the pass code has been successfully entered the PRG light in the bottom right corner of the numeric display will illuminate to indicate that the programming mode is active. 6.3.2 Changing Zone, Group and Common System Options. Now that the system is in programming mode the NEXT button will step sequentially through the program option sets (1,2,3,4,5,C,F,U,E,P, ) When the last program option set is reached the display will loop back to the first. Once in the required option set press the OPTION button until the required option flashes. Press the SELECT key to change the option setting. When the last option is reached pressing the OPTION button loop back to the first option. Some options cannot be selected whilst others are active. This applies to the HEAT, SMOKE and FLOW SWITCH options. If either the SMOKE or HEAT option is active for a zone then the FLOW SWITCH option may not be selected and vice versa. Note that the LED s on and off times for an active option are different from an inactive option. 6.3.3 Changing the battery voltage. Note: The battery voltage is factory set and should not normally be changed on site. However it may be necessary to do so if the EEPROM is corrupted or damaged. To increase the battery charge voltage, press the NEXT key until U is displayed. Press the select key until the required voltage is reached. It is recommended that changes be made slowly to allow the system to adjust the voltage. Reducing the battery charge voltage is similar to increasing the voltage except the display should show 6.3.4 Saving the options. To save the options, press the NEXT key until P is displayed. Press the SELECT key. The system will save the program options and return to normal operation. Confirmation of the action is given by a double beep. 6.3.5 Exiting without saving. To exit with saving the changes press NEXT until E is displayed. Press the SELECT key. Note that pressing reset or leaving the system without pressing keys for thirty second will also allow the system to terminate the option setting procedure and return to normal. Page 12

9.0 SYSTEM OPERATION 9.1 Resetting the system To reset the system after a fire, press the RESET button on the main board. This will return the system back to its normal state. The buzzer will sound for confirmation. 9.2 Isolating the Bells/Sounders Bells may be isolated by either pressing the Bell Isolate switch on the MAF, or by operating the Silence Alarms key switch on the outside of the cabinet. Pressing Bell isolate on the MAF will cause the buzzer to beep and the LED above the switch to illuminate. To return Bells to normal press the switch again. Note: Operating the key switch will cause a Defect signal to be sent. 9.3 Using the Walk Test facility To start the walk test facility, press the Walk Test switch on the MAF. The buzzer will beep once and the LED above the switch will illuminate. To avoid signalling the brigade, the Isolate switch on the SGD should be set to the Isolate position. If it is not desirable to operate the sounders then isolate the bell as detailed above. Do not close the door at this stage. See section 3.2.5. The detectors can now be tested. As a detector is set into alarm the system will operate as normal, except that after approximately three seconds the detectors on the circuit in alarm will be reset. After testing is complete press the Walk Test switch to return to normal. Return any other switches to normal before closing the door of the NZ400. 9.4 Self Test Facility To start the test, press the Test button twice. The system will now place each zone into fire and defect conditions sequentially. The test will terminate when finished. It may also be terminated at any time by another press of the Test switch. 9.5 Evacuation On the door of the NZ400 a key switch is provided for Evacuation, operating this key switch will cause the system to operate the bells. This will override any other bell isolate or silence condition. Page 16
