System Sensor SS-CO — intelligent addressable carbon monoxide detector, certified to UL 2075 for system connected life safety CO detection.
CO is colorless and odorless, and commercial codes increasingly require it to be watched by the fire alarm panel rather than by stand-alone alarms. The SS-CO reports an analog representation of CO density over the signaling line circuit and carries its own point ID, so no monitor module is needed.
- Carbon monoxide only; it senses neither smoke nor heat
- Supports SS, LiteSpeed and SK protocols; point addressable to 159 addresses
- Address set on two rotary switches, tens and ones
- 15 to 32 VDC, 200 µA operating and 2 mA maximum alarm current at 24 VDC
- Alarm thresholds per UL 2034: 70 ppm in 60 to 240 min, 150 ppm in 10 to 50 min, 400 ppm in 4 to 15 min
- CO cell life about ten years, signals its own end of life and is not field replaceable
Do not substitute the SS-PHOTO-CO, which adds photoelectric smoke detection on the same address, or the conventional CO1224 and CO1224T, which are not addressable. Local sounding needs a B200S sounder base.

FAQ
Is a base included?
No. The sensor base is supplied separately. System Sensor recommends the B200S series intelligent sounder bases, which sound a Temporal 4 pattern for CO alarm.
Does the SS-CO detect smoke?
No. It is a carbon monoxide detector only. The SS-PHOTO-CO and SS-FIRE-CO are the multi-criteria versions.
Which protocols does it support?
SK, LiteSpeed and SS protocol systems. Check the addressable detector and sounder base compatibility chart for your panel.
How long does the CO cell last?
The CO cell is rated for 10 years and the detector gives an end-of-life warning and fault.
