System Sensor SS-FIRE-CO — intelligent four-sensor detector giving fire and carbon monoxide detection on one SLC address.
Four sensing elements are read together by onboard algorithms, keeping it sensitive to a real fire while rejecting nuisance sources such as theatrical smoke. The CO cell also gives a separate life-safety CO signal, so CO and fire are reported as different events.
- Photoelectric, thermal with rate-of-rise and a 135°F fixed threshold, infrared and CO sensing
- Certified to UL 268 7th edition, UL 521 and UL 2075
- 15 to 32 VDC; 200 µA standby, 2 mA alarm, 4.5 mA maximum at 24 VDC
- CO response 70 ppm in 60 to 240 min, 150 ppm in 10 to 50 min, 400 ppm in 4 to 15 min
- Ten-year CO cell, not field replaceable, warns the panel near end of life; smoke sensing continues
- 32°F to 115°F, 15 to 90 percent RH, 0 to 4,000 ft per min
The base is supplied separately: B501 4 in., B300-6 6 in. flanged, B224BI isolator, B224RB relay, or a B200S sounder base, which gives separate audible signals for fire and CO. SS-PHOTO-CO is the photoelectric and CO version, without the thermal and infrared.

FAQ
Is a base included?
No, the base is supplied separately. System Sensor lists the B501 4 in. base, B300-6 6 in. flanged base, B224BI isolator base, B224RB relay base and the B200S series sounder bases.
Can it give different audible signals for fire and CO?
Yes, when it is installed in a B200S series sounder base, which sounds a Temp 3 pattern for fire and Temp 4 for a CO alarm.
Which panels can it be used with?
SS-Series detectors support SK, LiteSpeed and SS protocol systems. Check the Addressable Detector and Sounder Base Compatibility Chart for the specific panel.
How long does the CO sensor last?
It has a 10-year CO cell with an end-of-life warning and fault reported to the panel.
