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” always activate S1 even if sounders are disabled.
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, two 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.
Check sounder wiring for continuity. Short or open circuit indications must be rectified before connecting to the control panel.
All cable testing must be carried out with a Multimeter.
WARNING: Do not use a Megger when devices are connected.
Induced voltage higher than 1 Volt indicates possible cable problems or bad earth connection and must be rectified before
connection.
