BS-634, BS-636 4 and 6 zone Fire Detection Panels Description The family of fire detection panels consist of 2 types( 4 and 6 zone) with identical operation and indications. All of the panels have 2 independent siren outputs, Alarm relay, Programmable output for telephone operators and a relay pre zone . The required battery for the panels is the type Á-986 (12V/7Ah). All functions and indications are according to European Norms ÅÍ 54.

Starting from the top left indicators we can see 2 indicators marked 'Disable'. The 'General' LED lights to indicate a disabled zone, whereas the 'Zone' LED lights when a disabled zone is only one and blinks when we have more than one disabled zone. Going towards the right we can see two LED with the marking 'General'. The 'Fault' LED lights in every FAULT condition and blinks when we have a FAULT and the buzzer is silenced. The 'Alarm' LED lights when we have an ALARM condition and blinks when we have an ALARM and the buzzer is silenced. The next group of indicators is the 'Alarm' indications LEDs. These indicators light when a corresponding zone issues an ALARM condition. Below this group we have the 'Fault' indications for each zone. When the panel monitors an open or short circuit conditions in a zone then the corresponding LED will light. If the fault is caused by a short circuit then the corresponding LED will blink. If the fault is caused by an open circuit then the corresponding LED will light continuously. Below the `Disable` and the `General` indicator groups we can find another indication group called `Fault`. The LEDs marked 'Siren1' and 'Siren2' correspond to the siren outputs. If a siren out has a short circuit then the corresponding LED will blink whereas the LED will remain continuously lighted if the siren output is open circuited. The 'Batt' LED and 'Power' LED in combination, show us faults concerning the power supply. These combination are shown in the panel below. Lack of AC voltage Battery Overcharging Battery Discharged Battery Absent Charger Error Power Fault Lights Lights Lights Blinks Blinks Batt Fault ---- Lights Blinks Lights Blinks The 'CPU' LED lights to indicate a problem with the main processor unit. The green 'Power' LED lights to indicate valid internal voltages and blinks when the mains AC power supply is absent. Control keyboard description/operation The panel is controlled/ operated using the six numeric keys (1 to 6) found on the front panel. When a key is pressed a short tone is issued. The panel has three operation levels. Operation level 1 has all the functions that can be done directly from the user without using a code. These operations are: Buzzer silence / Buzzer reactivation . If an alarm of fault condition is issued then the internal buzzer will sound. Pressing the "1" key will silence the buzzer. ( The buzzer sounds periodically once every minute.) Pressing this key again will reactive the buzzer. Viewing disabled sirens-zones/Lamp test. Pressing the "2" key will have the following affect. If any sirens are disabled then the panel will issue 3 short tones, by lighting the ‘General Disable’ LED, and the disabled sirens will be shown by lighting the corresponding 'Alarm' LEDs Az1 and Az2 of the disabled sirens. Then the LEDs will stop lighting and the panel will issue again 3 short tone, by lighting the ‘Zone Disable’ LED, and the disable zones will be shown by the lighting the corresponding 'Alarm' LEDs of the disabled zones. After awhile these indications are switched off and a lamp test is conducted by lighting the LEDs. The panel then returns to normal operation. The above tests can be conducted only if the panel is in quiescent state (No fault or alarm conditions). Operation level 2 has all the functions that the user can do and an access code is required. The code is "345", it is the same for all panels and cannot be changed. The functions that can be implemented using this code are the following: Siren Silence. When an alarm is issued and we want to silence the sirens then we must enter the user code ( 345 ) and then the key number '5'. The sirens are silenced but the internal buzzer continues to sound. The panel remains in normal operation. A new alarm from another zone will resound the sirens. Page 2 from 7 921636000_09_012 Panel Reset. When an alarm or fault condition has occurred and we want to reset the panel we must enter the user code ( 345 ) and then the key number '6'. The panel lights all LEDs in sequence and then enters normal operation. Zone enable/disable. If we want to disable the operation of specific zones the we must enter the user code ( 345 ) and then the key number '4'. The LEDs marked 'Zone disable' and 'General disable' start to blink, and if a zone is disabled the corresponding 'Alarm' LED lights to indicate this. Using the keys 1, 2, 3, 4, 5 and 6 we can enable or disable the respective zones. The disabled zones have an 'Alarm' LED lighted. The panel exits this mode if no key is pressed for more than 30 seconds. The panel then conducts an automatic RESET and enters normal operation mode. All disabled zones are supplied with the proper voltage but cannot issue an alarm or fault condition. If we have disabled zones then this is indicated with the indicators 'General disable' and 'Zone disable' and the buzzer sounds once every minute. Siren enable/disable: If we want to disable the operation of specific sirens the we must enter the code ( 364 ) and then the key number '6'. The LEDs marked 'Zone disable' and 'General disable' start to blink, and if a siren is disabled Az1 LED lights for siren 1 and Az2 LED lights for the siren 2. Using the keys 1 and 2 we can enable or disable the respective sirens. The disabled sirens have an 'Alarm' LED lighted. The panel exits this mode if no key is pressed for more than 30 seconds. The panel then conducts an automatic RESET and enters normal operation mode. All disabled sirens are supplied with the proper voltage but the panel cannot enable them or read their condition. If we have disabled sirens then this is indicated with the indicator 'General disable' and the buzzer sounds once every minute. Operation level 3 functions are functions that are implemented during the installation and need the technical code to be accessed. The technical code is "364", it is the same for all panels and cannot be changed. The functions that can be implemented using the technical code are activation methods used for the relays and can be done only if the panel has not issued an alarm or fault condition. These methods of programming are: AUX RELAY programming. If we want to program the operation behaviour of the AUX RELAY we must enter the technical code ( 364 ) and then press the number key '5'. The 'General fault' and 'General alarm' LEDs start to blink . The Alarm LED of zone 1 and zone 2 show the way the AUX RELAY is programmed according to the table below. General Alarm Direct activation General Alarm Delay 45 sec General Alarm Delay 2 min General Fault Direct activation LED Alarm zone 1 LED Off LED On LED Off LED On LED Alarm zone 2 LED Off LED Off LED On LED On The default setting of this relay is set to activate from a general alarm and immediately with no delay. In this programming mode if the keys '1' and '2' are pressed , we can toggle the LEDs ON or OFF until we reach the desired activation behavior according to the table above. In order to exit this programming mode and to store the settings in memory press the key '6' or do not press any key for more than 30 seconds. This system will conduct an automatic RESET and will enter normal operation mode. ZONE RELAY programming. If we want to program the operation behavior of the zone relays then we must enter the technical code ( 364 ) and then press the number key '5'. The 'General fault' and 'General alarm' LEDs start to blink. The Fault LED of zone 1 and zone 2 show the programmed activation method of the zone relays according to the table below. Permanent activation Activated for 10 sec Activated for 30 sec Activated for 60 sec Fault zone 1 LED Off LED On LED Off LED On Fault zone 2 LED Off LED Off LED On LED On The default operation method for the zone relay is set to permanent activation. Using the keys '3' and '4' we can toggle the ON or OFF state of the LEDs until the desired activation programming has been reached. In order to exit this programming mode and to store the settings in memory press the key '6' or do not press any key for more than 30 seconds. This system will conduct an automatic RESET and will enter normal operation mode. We can also program the RELAY so that it can cooperate with BS-680 or BS-684 type electrovalves by shorting the adjustment jumper. In this case the RELAYS are activated for 10sec. during the alarm. After 10sec. they are deactivated. Page 3 from 7 921636000_09_012 Connections The three panels in the family have the same connections. The main differences in these panels is the number of zone available and the number of zone relays. The common outputs, the maximum consumption and the operation procedures are identical for all the panels. Connecting detectors and break-glass call points to zones. By default each zone terminal block has a pre-installed terminal resistor (5Ê6). This resistor is removed and installed on the last device of the zone or is left connected on the zone terminals if the zone is not used. The connections to all the zone are identical. What is shown in figures 1, 2 and 3 for zone 1 is valid for all the zones.

Besides the connections to the zone terminals these detectors must also be connected to the terminals 24V_M in order to be supplied with power. Page 4 from 7 921636000_09_012 Siren - Sounder Connections Each panel offers 2 independent circuits for connecting sirens, bells or other devices that need 24Vdc in order to operate. Each circuit can supply a maximum of 300mA. Each terminal block by default has a preinstalled terminal resistor (5Ê6). This terminal resistor is either removed and installed on the last siren of the line or is left on the terminal block if the circuit is not used. The connections of both the circuits are identical. 24V 12V GND 5Ê6 Terminal Resistor ALARM1 ALARM2 Terminal Resistor BS-531 Siren with Beacon 5Ê6 24V 12V GND BS-531 Siren with Beacon Figure 4. Connecting 2 BS-531 sirens to the ALARM 2 output. This connection requires polarity. Besides the terminals that were described up to now the panel also has the following outputs : 24V_M: A 24Vdc output that is interrupted in the event of a panel reset. It is mainly used for powering gas detectors or other devices that need an interrupted power supply when the panel is resetting. If this output is short-circuited then the LED marked 'General fault' is lighted. 24V_P: A 24Vdc power output that is not interrupted in the event of a reset. It can be used to power electromagnetic door latches. Relay AUX : Voltage free relay contacts that by default are programmed to operate when the panel issues an alarm condition. F_OUT : This output is by default programmed to operate in every fault condition issued by the panel. If it is required that this output be activated by an alarm condition then we must set the MODE switch 2 to the ON position. This output is an open-collector output suitable for controlling the BS-487 telephone operator. Zone Relays : Voltage free relay contacts that are activated in the event of an ALARM on the corresponding zone. All panels offer a relay per zone. We can use these contacts to activate devices or operations that must be done when a specific zone issues an alarm ( e.i. Activating electromagnetic door latches, activating electro-valves ). Figure 5 shows such an installation. BS-510/24 24V DC 24V DC 24V_P BS-510/24 NO C NC NO C NC ZONE 1 ZONE 2 Figure 5. Connecting 2 electromagnetic door latches BS-510/24 to the panel. One is activated by zone 1 and the other by zone 2. The panel also has 2 battery connection cables. The red connector goes to the positive (+) terminal whereas the black connector goes to the negative (-) terminal of the battery.

Connecting the mains power (220-240Vac) The mains connection terminal block is located over the battery compartment and beside the transformer. The connection is done using the two outer terminals as shown in figure 6 with double insulated cable and does not require a ground. Initial Installation N 220-240V L Figure 6. Connecting the panel to 220-240Vac. When the connections to zones, sirens and other required outputs are finished then we must connect the mains power supply. Before connecting the mains power supply be sure to isolate it to avoid electrical shock. In order to aid the installer during the initial installation, the panel offers a special configuration. This configuration is entered by setting MODE switch 1 to the ON position. After entering this mode the panel conducts a auto reset and the 'Power', 'Zone disable' and 'General disable' LEDs blink. The special functions that aid in working out various problems that might arise are : Warnings. 1. During the installation the connections to the mains power supply and the battery must be done after all other connections are finished. 2. The panel connection with the mains supply must be done via a 16A external fuse or an automatic circuit breaker rated at 16A. 3. Always use cables with double insulation. 4. The diameter of the cable must be at least 1mm. 5. The inner insulation of each cable must not be cut more than 1cm 6. The outer insulation must not be cut more than 1cm away from the internal insulation. 7. The panel's internal fuse is Ô630mA with 5x20 dimension. Page 6 from 7 1 cm Fuse: T630mA/5x20 1 cm L N 921636000_09_012 When a zone has an open circuit then the internal buzzer sounds and the corresponding LED lights. If the problem is corrected then the buzzer is deactivated and the LED is extinguished. When a zone has a short circuit then the internal buzzer sounds and the corresponding LED blinks. If the problem is corrected then the buzzer is deactivated and the LED is extinguished. When a siren output has an open circuit then the internal buzzer is activated and the corresponding fault LED lights. If the problem is corrected then the buzzer is deactivated and the LED is extinguished. When a siren output has a short circuit then the internal buzzer sounds and the corresponding LED blinks. If the problem is corrected then the buzzer is deactivated and the LED goes Off. When a battery fault exists then the 'Batt fault' LED lights and the 'Power fault' LED blinks. If the problem is corrected then the LEDs are deactivated. If all the problems are corrected and the installation is operating normally then the MODE switch 1 must be placed in the OFF position. The panel conducts a auto-reset and is ready for operation. Walk - Testing By using a special operation mode we can conduct a walk test of the system. To enter walk-test mode set the MODE switch 1 to the ON position. The 'Power', 'Zone disable' and 'General disable' LEDs blink. If an alarm is manually given by either activating a BS-536 call point or by activating a smoke detector with smoke or simulated smoke particles the corresponding Alarm LED of the zone will light and the siren will sound for 2 seconds. Using this method we can test the operation of the zones. In this state if we press the number keys 1, 2, 3, 4, 5 and 6 then the corresponding zone relay will be activated. All devices that are connected to these relays will also be activated indicating that they are operating properly. After finishing the walk test set the MODE switch 1 to the OFF position. The panel conducts an automatic reset and enters normal operation mode.
