Installing the Coded Battery Backup Siren (BBSC / MiniBBSC):
Red - 12V Siren Power:
Connect to permanent 12v power source – a spare GND wire is available from the main alarm loom to assist ease of wiring.
Black – Siren Ground:
Connect to an earth point on vehicle chassis – a spare GND wire is available from the main alarm loom to assist ease of wiring.
White – Siren Data Input:
Connect to wire 16 “-SIREN” on the main alarm loom. Multiple data sirens can be connected to a single alarm system with the
white data wires joined in parallel.
Green – Negative on Alarm Output:
Gives a constant 200mA negative output (-alarm) when the alarm is triggered. This can be used to run an additional
piezoelectric siren directly or activate a larger siren / vehicle horn through an external relay.
Brown & separated black – Bonnet Wires:
These two wires are looped together inside the siren and are used to assist in wiring the bonnet pin switch without needing to
extend the standard loom. Wire 20 from the main alarm loom should be wired to the brown wire, and the pin switch should be
wired to the separated black wire.
