SOUNDER CIRCUIT WIRING
There is only one conventional sounder circuit available on the ORION BCM LSC (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 LSC Panel button
(access level 2) or by remote input (EV).
NOTE:
The Fire output Relay will also be activated in case of Sounder Circuit ON.
An end of line resistor (10k Ohm) which is 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:
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.
