The Sigma CP Sounder board can to provide up to 8 additional sounder outputs from Sigma CP conventional fire panels via a 2 core data bus and an additional power supply.
Sounder outputs are configurable as common, zonal or two stage alarm.
The Sounder board is compatible with all Sigma CP control panels with software versions Sigma242.hex onwards.
Up to 7 Sounder boards can be connected to a control panel and each is allocated an address from 1 to 7 using a binary coded DIL switch.
All sounder outputs are voltage reversing and monitored for open and short circuit faults using a 10K end of line monitoring resistor.
The Sigma CP control panel power supply is not suitable for powering these sounder boards.
