The Sigma CP Sounder Board is compatible with all Sigma CP control panels which have operating software version V3.0 or above.

The board provides 8 additional sounder outputs which can be configured as zoned, 2-stage or common alarm.

All sounder outputs are open and short circuit monitored and any faults on the sounder outputs will be announced at the main fire alarm panel as a sounder fault.

A class change input is provided which, when activated by a volt free contact closing, will switch all sounder outputs on.

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. Sounder boards may be connected to the Sigma CP serial bus in addition to Sigma CP ancillary boards and Sigma CP-R repeater panels.

The total length of the data cable from the main panel to the last repeater must not exceed 1200 metres.
