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.
