MOUNTING PANEL
The ORION BCM housing is designed for either surface or semi-recessed mounting. Cable entry points are provided at the
top and back of the housing. Do not drill additional holes as cables could then interfere with the PCB or standby battery
position. Maintain separation between the incoming AC mains cable and the low voltage detector and sounder cabling.
The panel should be fixed to the wall using the 4 mounting holes provided and No 8-10 countersunk screws. Any dust
created during the fixing process must be kept out of the control panel and care must be taken not to damage any wiring or
components.
CABLE TYPES
System wiring should be installed in accordance with National Standards and wiring regulations.
To protect against electrical interference we recommend the use of screened cables throughout the system. Separate cables
should be used for sounder circuits, the use of multi-core cables to carry sounder circuits is not recommended. The cable
screens should be terminated and connected to Earth at the panel only.
Maximum cross section of cables to use is 2.5mm² to avoid damaging the terminals in the control panel.
Mains wiring should be 3 core 1mm² to 2.5mm² fed from an isolating circuit breaker of 6A. This should be secure from
unauthorized operation and be marked “Fire Alarm Do Not Switch Off”. The mains supply must be exclusive to the fire panel.
SOUNDER CIRCUIT WIRING
There is one conventional sounder circuit available on the ORION BCM (S1). The maximum current available for sounder
circuit is 900mA.
All sounders must be polarized; non-polarized sounders will indicate a fault on the sounder circuit.
The sounder circuit can be activated from the Addressable Panel, by direct activation from ORION BCM Panel button
(access level 2) or by remote input (EV).
NOTE:  The Fire output Relay will also be activated with Sounder Circuit ON.
An end of line resistor (10k Ohm) supplied with the panel, must be inserted in the last sounder for cable monitoring. If a
sounder circuit is not used, the EOL resistor should be fitted in the control panel sounder output.
The sounder circuits are protected against short circuits, the electronic fuse will reset when the short circuit is removed and
the control panel is reset. The wiring for each sounder circuit should be terminated in their respective terminals and the cable
screens connected to earth.

Typical sounder circuit wiring diagram:
Polarized Sounders
Non-Polarized Sounders (with 1N400x diodes)
OUTPUTS
Auxiliary Power
28V DC max 900mA, short circuit protected, supervised. The output is protected against short circuit by an electronic fuse
which resets when the fault is cleared and the panel is reset.
Auxiliary Relay Contact Fire
Provides “Fire/Sounder Active” signal to external devices. This is activated through direct panel sounder button activation.
Relay contact changeover 2A @ 30V DC resistive / 0.25A @ 230V AC resistive. Active until Reset or Sounder OFF.
Auxiliary Relay Contact Fault
Provides Fault signal to external devices. Relay NC contact 2A @ 30V DC resistive / 0.25A @ 230V AC resistive. Also
Active for microprocessor fault. Active until Reset and all faults are cleared. Relay contact will open when any fault is present
on the system. The wiring for each output should be terminated in their respective terminals and the cable screens
connected to earth.
INPUTS
To activate the inputs, a shunt must be made between the Common “C” and the input to be activated by the means of a dry
contact switch (no voltage).
INPUT “DE” - Fire Relay
The “DE” input will activate the Fire Relay. Connect it to “C” input for activation.
INPUT “EV” - Sounder Circuit
The “EV” input will activate the Sounder Circuit. Connect it to “C” input for activation.
NOTE:  “EV” will always activate S1 even if disabled sounders.
CONNECTING THE PANEL
The mains supply should be routed away from the other cables and enter the control panel adjacent to the mains terminal
block. Wiring to the Mains supply should only be undertaken by a suitably qualified and competent person.
Depending on ORION BCM load and standby requirements, to 12 Volt valve regulated lead acid batteries with the capacity
up to 7Ah may be fitted in the housing. The batteries should be wired in series (24V) using the supplied link. Take care not to
short circuit the battery terminals.

Ensure that all EOL Resistor are fitted to the last sounder of each circuit
2. Connect sounder lines to panel
3. Remove the mains fuse
4. Connect mains supply according to local mains voltage ensure good earth connection
5. Fit batteries (do not connect)
6. Insert mains fuse
7. Connect batteries - Observe correct polarity.
Commissioning
1. If all is normal only the Green “supply”LED should be illuminated.
2. If any Faults are indicated they should be corrected before proceeding.
3. Initiate lamp test and confirm LEDs and internal buzzer operation.
4. Test each key for correct functioning.
5. Test all sounders, relays etc. for proper operation.
TESTING FIELD EQUIPMENT
Testing Sounders
1. Introduce the Level 2 Access code (2244) with the Buzzer OFF
2. Initiate sounder pressing Sounders Activate/ Silence
3. Press again to Stop.
Testing Relay Outputs
With the Addressable system in normal operating mode, activate a Fire Alarm and confirm operation of Fire relays. Test if
manual button Sounder activation, also activates the Fire relay.
On the Fault Relay test, generate a fault (example: remove the sounder circuit EOL or remove Mains Power) and verify the
Fault relay operation.
STANDBY BATTERY CALCULATION
Battery capacity should be between 2 x 2.4 Ah 12V DC and 2 x 7 Ah 12V DC.
The battery Ah required for a given installation is calculated from the following formula:
(
38mA
X
Standby time
required in hours
divided by 1000
)
+
(
Alarm & Aux. Supply
Outputs in Amps
(sounder & aux. supply load)
X
Alarm time in
hours
)
+
20%
Round the result to the next available battery size. Quiescent current of the panel with everything is found by adding the
standby current of all connected devices to the standby current of the panel (38mA). Consult the manual for the individual
devices to confirm the standby current.
Troubleshooting - Fault Indications
Troubleshooting work of any fault on the panel should only be carried out by qualified technicians.

General Fault
The General fault LED is illuminated whenever there is a fault on the system. It is always lit along with at least one other fault
indicator which gives more detail relating to the fault.
Power Supply Faults - Supply Fault
Associated with a low voltage (below 20V) present at the input of the power supply or the removal of the main power supply.
Measure voltage levels and verify electrical mains fuse.
Battery Fault
This fault is present when there is a voltage below 20V DC at the battery terminals or if there is a battery charger problem.
Charger problems can be caused by panel's hardware failure or batteries that have not been connected in the specified
manner as indicated in this manual, in the installation section. Verify if batteries are properly connected. Measure the voltage
at the battery terminals and replace if it is below 21V DC. Remember to verify also the main electrical fuse.
DON'T SHORT CIRCUIT BATTERY TERMINALS IN ORDER TO VERIFY BATTERY CHARGE ONLY USE
BATTERIES THAT ARE LEAD ACID VRLA TYPE 12V DC.
Aux Supply Fault
This fault will show when the voltage at the auxiliary supply output is below 20V DC. This can be caused by the current limit
for this output being exceeded. This output is limited to 900mA. Other causes for faults at this point are short circuits in the
wiring or faulty hardware attached to this supply output. Verify voltage, if below the required acceptable level remove wiring
connected to this output. If voltage now returns to normal this confirms that connected equipment or cable is damaged.
Earth Fault
This FAULT will indicate that there is some level of current leakage between any of the wire conductors and the EARTH
connections. VERIFY WIRING.
System Fault
This FAULT indicates that there is a fault at the main processor level. In this particular fault, the panel's main board needs to
be replaced or repaired.
Example of application (External switch Sounder Activation)
This implementation has the ability to, by using two external independent switches on the inputs, overlap (the addressable
order) the Sounder Output or the Fire Alarm Relay state.
NOTE:  Alternatively both “DE” and “EV” could be connected in parallel, so that the Fire Relay and S1
actuate simultaneously using only one “dry contact switch”

Example of application (Door Holder)
This implementation has the ability to, by pressing the ORION BCM sounder activation key, manually release all door
holders connected to the AUX PSU in addition to the Programmed Sounder activation.
NOTE:  It will “release” the Door Holders in case of FIRE or Direct Button Activation
(by activation of Fire Relay).
Example of application (Door Holder Supply/External Control)
This implementation, working as a standalone PSU, has the ability to, by pressing the ORION BCM sounder activation key,
activate Sounder circuit and manually release all door holder connected to the AUX PSU (in addition to the Addressable
System activation using an IO module).
NOTE:  It will “release” connected Door Holders in case of local ORION-BCM Sounder Activation (by
activation of Fire Relay)
