Page 5 2 MONITORINGS (WITH FAULT EXPLANATIONS) All fault warnings are indicated on the display with an optical and an audible signal. Fault warning origins are specified, either by means of a monitor specific LED, or by means of a fault explanation, displayed on the alphanumeric display. This section describes the operation of the monitorings in various situations in order to assist the service personnel to determine the reason for a fault warning. The best way to clarify the reason for faults is to silence first the common fault warning, to disconnect those faulty objects from keyboard, to reset fault warning. Then the faulty object can be selected and set to test state from keyboard. 2.1 MONITORINGS OF ZONES Each zone is terminated by an Active Terminator (AT), which creates a current pulse every 70 ms. The 1 ms pulse is created by changing the input resistance of the terminator from the normal 7.4 kohm to 50 ohm. Maximum cable resistance of a zone may be 100 ohms (not including the terminator). Maximum total leak current of the detectors may be 3 ma. Zone voltage is measured over two resistors between the negative terminal ( Zone(-) ) of the zone and ground ( Gnd ) (ie. the negative terminal of the 24V supply on the Controller board). The resistors are a 220 ohm and a 80 ohm in series. The measuring circuit is shown in Error! Unknown switch argument.. The signals AD, SC and RU are connected to the Controller Board. AD is dc voltage level with range 0-5 V. SC is digital pulse detection signal (Fault or OK, OK = pulse detected). RU is digital pulse detection signal (Fault or OK, OK = pulse detected). Supply (24Vdc) Zone DC voltage level AD 120 ohm 80 ohm Pulse voltage level Pulse voltage level SC RU Figure Error! Unknown switch argument. Monitoring circuit on Zone board

2.1.1 Normal state Page 6 Monitoring: In normal state the dc voltage level between Zone(-) and Gnd is 0.8V - 3V (normally approx. 1.2V) depending on supply voltage level and amount of detectors in zone. Pulse voltage level (measured from same point) is higher than 11V ± 1V (normally approx. 16V). Normal state = [(0.8V < AD < 3V) and (SC = OK) and (RU = OK)]. 2.1.2 Fire State Evaluation of Fire State is depending on jumper settings on the Zone Board (see Error! Unknown switch argument. ). If the jumper setting implies that a short circuit is to be indicated as a fault, both the AD signal and the SC signal are used for fire state evaluation, otherwise only the AD signal. Short circuit detection (with fault indication) requires that the resistance of detectors and other zone components (when in fire alarm state) are 250 ohms - 1000 ohms. (Eg. resistance in manual call point is 470 ohms). Monitoring: Dc voltage level (AD) between Zone(-) and Gnd is over 3 V and the difference between the pulse voltage level and dc voltage level is > 2.8 V. If short circuit is detected as fire (depending on configuration) pulse voltage level has no meaning. Fire State = [(AD > 3V) and (SC = OK)] Fire State = [(AD > 3V)] if short circuit is fault if short circuit is fire 2.1.3 Line Broken Cable resistance of zone has radically increased (over 3 kohms with 27V supply) (terminator not included). Monitoring: Dc voltage level between Zone(-) and Gnd is lower than 0.8V. Pulse voltage level is not measured. Line Broken = [(AD < 0.8V)] 2.1.4 Line Fault Cable resistance of zone is over the fault limit ( 200-400 ohms). (If cable resistance is in normal area (resistance is lower than 100 ohms) and this fault is indicated, monitoring circuit on zone board or/and on controller board is out of order) Monitoring: Dc voltage level between Zone(-) and Gnd is normal (0.8V - 3V), but pulse voltage level (measured from same point) is lower than 11V ± 1V. Line Fault = [(0.8V < AD < 3V) and (SC = OK) and (RU = Fault)]

2.1.5 Short Circuit Page 7 Evaluation of Short Circuit is depending on jumper settings on the Zone Board (see Error! Unknown switch argument. ). If the jumper setting does not imply that a short circuit is to be indicated as a fault, a fire alarm will be indicated. Monitoring: Dc voltage level between Zone(-) and Gnd is over 3V and pulse voltage level (measured from same point) minus dc voltage level is lower than 2.8V. Short Circuit = [(AD > 3V) and (SC = Fault)] 2.1.6 Monitor Fault This fault is detected if zone is in order (no above mentioned faults) but monitoring circuit on zone board or/and on controller board is out of order. Monitoring: Constantly: Dc voltage level between Zone(-) and Gnd is normal (0.8V - 3V), and pulse voltage level (measured from same point) is normal (higher than 11V ± 1V), but part of pulse detection circuit is out of order. Monitor Fault = [(0.8V < AD < 3V) and (SC = Fault) and (RU = OK)] Every 24h: The supply of all zones is turned off for 1 second. During that time the values of the zone interfaces are measured. If the circuit is in order, all measured values ought to be in fault state. Monitor fault = [(AD > 0.8V) or (SC = OK) or (RU = OK)] 2.1.7 During Zone Test When Zone Test is active, fire alarms or fault warnings for that zone are not activated. The state (Normal, Fire, Break, Short or Line fault) of the zone under test, is indicated on the display only. The monitoring limits of each state are the same as in normal state. 2.1.8 During System Test The zone interface circuits of all zones are tested during system test. Monitoring First the supply of all zones is turned off for 1 second. During that time the values of the zone interfaces are measured. If the circuit is in order, all measured values ought to be in fault state. After that, the zones are shown one by one on the display. If a fault was detected in any zone interface circuit the type of the nonworking circuit is indicated when that zone is on the display. Codes on the display (see also figure ): "B" if AD is not < 0.8 "L" if RU is not Fault "S" if SC is not Fault Comparable codes with "BLS" (english) in different country versions:

Finnish: "KLO" Norwegian: "ALK" Swedish: "ALK" Danish: "LSK" Page 8 2.1.9 Zones used in Explosive Atmospheric Environment Zone(s) 1 and/or 2 can be configured to operate in EX-environment. In this case the active terminator (AT-1) is replaced by an end of line resistor (4.7 kohm). Only AD value (see Error! Unknown switch argument.) is measured. Short circuit is always indicated as fire. Fire threshold is a fixed value. Fault thresholds are floated with level of the supply voltage. Monitoring: Fault = [(AD < (1.1 V * Vsupply/26.5V))] 95-09-05 IN Normal = [((1.5 V * Vsupply/26.5V) < AD < 3 V)] Fire = [(AD > 3 V)] Deleted: Fault = [(AD < (1.5 V * V supply /26.5V))] 2.2 ALARM DEVICE LINE MONITORING A fault is indicated if there is short circuit or break in the lines. During fault warnings, numbers 1-4 on the display refer to numbers of the alarm device line terminals. Number 5 on the display refer to AM input on Controller Board (see section 2.3 Input monitoring). 2.2.1 Normal state Alarm device lines (AL) are monitored with reversed polarity ( AL(-) is positive and AL(+) is negative). Therefore, all alarm devices are provided with diodes and the lines with End-Of-Line resistors (4.7 kohm). The fuses of these lines (F1 - F4) are monitored by the same circuit. Thus, a blown fuse is indicated as alarm device line fault. Monitoring Fault is detected if voltage level between AL(+) and Gnd is < 1.8 V (resistance in line is < 1 kohm) or voltage level is > 8.9 V (resistance in line is > 13 kohm (end of line resistor 4.7 kohm included). Normally the measured value is 4 V. These voltage levels are floated by a factor Vsupply/26.5V where Vsupply is voltage level measured from the 24 V supply terminals on the Controller Board. Fault = [(AL(+) < 1.8V) or (AL(+) > 8.9V)] 2.2.2 Test State The fault limits: Lower limit is 2.5 V (resistance in line is 2 kohm). Upper limit is 6.7 V (resistance in line is 9 kohm (end of line resistance 4.7 kohm included). These voltage levels are floated by a factor Vsupply/26.5V where Vsupply is voltage level measured from the 24 V supply terminals on the Controller Board Measured values of lines 1-4 are indicated on the display. Fault = [( AL(+) < 2.5V) or ( AL(+) > 6.7V)]

Page 9 2.3 INPUT MONITORING (INPUTS IN1 - IN3 AND AM) At normal state the input is closed (ie. the terminals are shorted). An input is activated by opening the input line. The input lines IN1 - IN3 activate corresponding leds on the display panel. The AM input activates an alarm device fault (line number 5). Monitoring: Lines are activated if voltage level between terminals is > 6.7 V (resistance is > 5 kohm). 2.4 EARTH LEAKAGE MONITORING Earth leakage is monitored with respect to both the positive and the negative supply voltage poles. The cabinet (earth) is connected to the monitor circuit via the two mounting screws in the lower corners of the Controller Board. Fault warning is indicated if the resistance from either pole to the earth is less than 22 kohms (30 kohms during system test). The faults are indicated as "FAULT -" or "FAULT +". Monitoring in normal state: Normally the voltage level between cabinet and Gnd (ie. negative of 24V supply on the Controller board) is 9.4 V. "FAULT -" is indicated if voltage level is < 5.3 V FAULT +" is indicated if voltage level is > 16.5 V These voltage levels are floated by factor Vsupply/26.5V where Vsupply is voltage level measured from eg. 24 V supply terminals on the Controller Board Monitoring during system test: "FAULT -" is indicated if voltage level is < 6.0 V "FAULT +" is indicated if voltage level is > 15.5 V (These levels are also floated.) Monitoring in test state: Measured voltage level is indicated on the display. The fault limits are same as in normal state.

2.5 FUSE MONITORING Page 10 All fuses are monitored. The indication of a blown fuse varies depending on which circuit it protects: Controller Board fuses: F1 - F4 protects the alarm device lines. Breaks of these fuses are indicated as alarm device fault. F5, F8, F9 protects the three 24 V supply outputs on the Controller Board. Breaks of these fuses are indicated as fuse fault. F6 and F7 protects the battery circuit. Breaks of these fuses are indicated as battery fault. Zone Board fuse: Fuse on Zone Board protects the zone circuits of that board. Break of this fuse is indicated as "zone fault - line broken" (faults in all eight zones of that board). Power supply: Break of fuse located in the power supply is indicated as charger fault (with fault code 6). Monitoring of fuses F5, F8 and F9 in all states: Fuse fault is indicated if the voltage measured over any of the fuses is over 1.7 V. 2.6 MONITORING OF FIRE AND FAULT ROUTING EQUIPMENT 2.6.1 Fire Relay (RL8) The coil circuit of the fire routing relay is monitored. A break in the coil circuit or a fault in the control circuit is indicated as fire routing equipment fault. The relay is normally de-energized. Monitoring in normal state: The coil resistance is measured and if it is over approx. 150 kohm it is indicated as a fault in the coil circuit. (Co8 < 1.2V; normally approx 4.2V) Every 60 seconds, the relay is energized for a few microseconds. During this short activation time the relay will not operate but the control circuit and coil can be measured for breaks or short circuits. Monitoring in test state: The same measuring and temporary activation as in normal state are performed. As the result of the test, the digits "1" and "0" (corresponding to successfull test) are shown on the display. The first ("1" = OK) indicates the result of the resistance measurement, and the second ("0" = OK) indicates the result of the temporary activation. 2.6.2 Fault Relay (RL9) The coil circuit of the fault routing relay is monitored. A break in the coil circuit or a fault in the control circuit is indicated as a fault routing equipment fault. The relay is normally energized. Monitoring in normal state: The coil resistance is measured and if over approx. 2 Mohm, it is indicated as a fault in the coil circuit. (0.6V < Co9 < 4.0V; normally approx 1.0V) Every 60 seconds, the relay is de-energized for a few microseconds. During this short activation time the relay will not operate but the control circuit and coil can be measured for breaks or short circuits.

Page 11 Monitoring in test state: The same measurements and temporary activation as in normal state are performed. As a result of the measurements two values are displayed. The first value is measured when the relay is in normal state and is normally 1.0, fault limit is 0.6. The second value is measured during the temporary activation (de-energization) and is normally 5, fault limit is 4. 2.7 BATTERY AND CHARGER AND MAINS MONITORING The battery is monitored with respect to: low voltage battery capacity fuse blown or circuit broken The battery charger is monitored with respect to: high voltage, regulator fault forced charge activation lack of current supply even if main supply is OK test discharge circuit faults charge current control circuit The main supply is monitored for absence. Each of these monitor functions has its own identificator, which is displayed at fault warning. Battery fault 1 Battery fault 2 Battery fault 3 Charger fault 4 Charger fault 5 Charger fault 6 Charger fault 7 Charger fault 8 Mains fault 9 If voltage level of battery is < 23.5 V. (For example during a long mains break). If the battery circuit is broken (eg. blown fuse or loose connectors). If capacity of battery is too low. If voltage level of battery is too high or the regulation in power unit or control circuit of forced charge is out-of-order If voltage level of battery doesn't increase during forced charge control. If mains is on and Control Panel doesn't get supply voltage from power unit. If the test discharge circuit is not in order. If charge current control circuit between power unit and battery is shorted. If mains is off. (The time interval between start of mains break and fault warning depends on country version: norwegian version: 0.5 h, danish version: 10 h, swedish version: 3 h, finnish version: this fault is not indicated). Monitorings in normal state: Voltage level of battery and charger are measured every 100 ms. Running average values are calculated and stored in system memory. Short (20 ms) discharge test of battery and evaluation of measured values are done every 10 s. Forced charge test and battery capacity test are activated 1 min. after start up of the system and then after every 24 h. (Duration of these tests is 20 s)

Page 12 Power unit Uc Control circuit Ub F4A F4A Load resistor located in power unit The power supply tests are done as follows (see Error! Unknown switch argument. ): Ubm = average battery voltage in memory (measured every 100 ms.) Ucm = average charger voltage in memory (measured every 100 ms.) Ub = battery voltage (measured during current test) Uc = charger voltage (measured during current test) Ufc = forced charge voltage (measured during forced charge test) Fc = forced charge state Test Indication if fault Possible reason a) Ubm < 23.5 V battery fault 1 b) Ubm > 28.0 V and not Fc charger fault 4 Charger is turned off and the short (20 ms) discharge test is activated. c) Ub < 21.0 V battery fault 2 break in battery fuses or loosened contacts d) Uc < Ub charger fault 6 system doesn't get supply from power unit altough mains is on e) Uc < (Ucm - 0.55 V) charger fault 8 circuit between power unit and battery is shorted If time to make forced charge test and long discharge test: - Forced charge is activated (duration is 20 sec.) f) Ub < (Ubm + 0.28 V) charger fault 5 voltage level of battery doesn't increase enough - Ufc is measured (in preparation for the next test) - The charger circuit is opened (but charger output is kept on the forced charge level) and 20 sec. load test is activated g) Ub < 21.0 V battery fault 3 the capacity of battery is too low h) Uc < (Ufc - 0.55 V) charger fault 8 circuit between power unit and battery is shorted i) Ub > (Ubm - 0.44 V) charger fault 7 discharge test circuit is out-of-order End of test Figure Error! Unknown switch argument. Charger and Battery circuits on Controller Board

Page 13 Tests a) and b) are done every 10 sec.. Tests c)... e) are done every 10 sec. if mains is on. Tests f)... i) are done every 24 h and 1 min. after system start up, provided that Ubm > 26.5V and forced charge is off. In addition these tests are also performed after a reset of faults 3, 5, 8 and 7. Only test a) is done if charger monitoring is disabled or charger is in fault state. Only test b) is done if battery monitoring is disabled or battery circuit is in fault state. Forced charge is activated if Ubm < 23.5 V or voltage level of discharged battery < 21.0 V. Forced charge is deactivated when voltage level of battery has been over 28.0 V for 5 h. Maximum time for continuous forced charge is 72 h (in case the battery voltage doesn't increase over 28.0 V). The long discharge test is always performed after deactivation of forced charge Battery monitoring in test state: Measured battery voltage is indicated on the display. If the Control Panel is not in service state the actual battery/charger circuit voltage is displayed. However, before the voltage is displayed, a short (20 ms) discharge test is performed (with the charger disconnected) and if the test givs a result < 23.5V, that voltage is displayed instead of the 'charger connected' voltage. If the Control Panel is in service state (see section Service state) the discharge test is activated and the measured battery voltage is displayed. The discharge test continues until the test is terminated manually, or by a time limit of 5 min. Charger monitoring in test state: Measured value of charger is indicated on the display. If the Control Panel is not in service state the charger circuit is opened and the measured charger voltage is displayed. If the Control Panel is in service state (see section Service state) the forced charge control is activated and the measured charger voltage is displayed. 2.8 PROGRAM MONITORING The internal system is supervised by the processor. System faults are indicated on the display with steady "GENERAL FAULT" and "SYSTEM FAULT" indicators and with an audible signal. If a system fault is detected during start up, only fault routing equipment control is activated, otherwise also other configured fault controls are activated. Fault origin is specified by means of a fault code, displayed on the alphanumeric display: 1 = program memory corrupted 2 = data memory access fault 3 = Alphanumeric display response fault (or no information at display) 4 = AD-converter response fault 5 = data structure of timeout queue fault 6 = data structure of communication queue fault 9x = unexpected interrupt x=interrupt number WARNING! Normal operation of the fire control panel is stopped when a system fault is detected. The execution of the running program is monitored by a HW-watch-dog, located on the Controller Board. The watch-dog will reset the system, if not updated by the program every 200 ms.

Page 14 3 SERVICE STATE The Control Panel is set into service state by shorting (for a moment) the "service jumper" on the Controller Board (see Error! Unknown switch argument.). Control Panel returns to normal state when the front door is closed. Functions in service state: In normal state (except the Norwegian version) the Control Panel gives an acoustic fault warning and activates the fault alarm device relay for 3 s every 5th min if the front door is open. In service state this warning is disabled. In normal state a selection is cancelled and the display returns to the state before the selection, after 15 seconds of no keypresses. In service state the time limit is 5 minutes. During battery monitor test the battery is discharged. During charger test the forced charge is activated. During system test the zone interface test result is displayed 0.3 seconds per zone. (Normally the time is 2 sec./zone). 4 SYSTEM SETTINGS Outputs are configured with DIL switch S and jumper field J on the controller board (see Error! Unknown switch argument.). Selections are shown in Error! Unknown switch argument. and Error! Unknown switch argument.. Zone outputs and characteristics are configured with jumpers J1..

Page 20 8 POWER SUPPLY REPLACEMENT The system has to be de-energized before replacing the power supply by disconnecting the battery cable and the mains plug. The power supply is removed by first loosening (two turns) four screws through four holes in each corner of the power supply by screw driver (type: pozidrive nr. 1, minimum lenght 80 mm, maximum diameter 4.5 mm) and then moving the power supply up 1 cm and then pulling it out from cabinet. See Error! Reference source not found.. The new power supply is installed in opposite order as removing. Charger voltage adjustment NTC RESISTOR 27.2V J1 J2 X4 X4 GND

Page 21 REPLACING THE CPU-BOARD IN MINI-2000 WHICH HAS THE OLD POWER UNIT: - Cut the "short circuit"-wires on the right side of the CPU-board (see figure). - Check that the resistor R64 (47 k) has been installed to the board. REPLACING AN OLD POWER UNIT WITH THE NEW ONE: - Add the "short circuit"-wires over the resistor R64 and diode D24 on the right side of the CPU-board ( see figure). - Check the new power unit, J2 (short circuit piece) has to be installed and J1 has to be removed (cutted wire). - Replace the NTC resistor with 10 kiloohms resistor. (in old power unit there is not temperature compensation and the program cannot monitor the new power unit with compensation). - Check the voltage level of power unit (before connecting the cabel between CPU and power unit.) The level should be 27.2 +/- 0.1 V measured between two pins of connector X4 (see figure) in power unit. Adjust that level if needed. - Attach the cable (ESMI code 24713800, to be ordered separately) to the connector X4 on the new power unit and to the connector CO3 on the CPU-board.
