System Sensor SS-PHOTO-CO Addressable Photoelectric Smoke and CO Detector, White, No Base

This intelligent multi-criteria detector combines photoelectric smoke detection with carbon monoxide (CO) detection in one device. Designed for installations such as hotels, schools, and high-rise residences, it provides both detection functions while using only one address on the SLC.

Features include automatic drift compensation for the smoke sensor and CO cell, RealTest CO testing capability, and a 10-year CO cell with end-of-life warning and fault indication. When used with a compatible B200S series base, it provides separate audible signals for fire and CO alarms. Listed to UL 268 7th Edition and UL 2075, it has a modern profile and is available in expanded color options.
