Description
The Intelligent CO / Low Frequency Sounder Base (45681- 805ADV) is an analog/addressable combination carbon monoxide (CO) detector and low frequency 520Hz sounder base for use with Advanced fire alarm control panels. In addition to carbon monoxide monitoring, the CO / low frequency sounder base can accommodate any Advanced intelligent smoke, heat or multi-sensor detector. For stand-alone CO detection applications a blank low profile cover is available (45681-292).
The built in low frequency 520Hz sounder of the Intelligent CO / Low Frequency Sounder Base can provide both a 520Hz temporal 3 (fire alarm event [via installed detector]) and 520Hz temporal 4 (CO event) signal, with the temporal 3 having the highest priority. The low frequency sounder base portion of the Intelligent CO / Low Frequency Sounder Base requires a separate regulated 24VDC supply. The separate 24VDC supply, can be from an Axis AX Notification Appliance Circuit (NAC) or from a Listed, supervised, power supply.
