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.
