FIRE/CO ADDRESSABLE DET

World-class fire and carbon monoxide (CO) detection combined in a single addressable device provides a practical solution for today's market.

The SD355CO Advanced Multi-Criteria Fire/CO Detector is a plugin, addressable device that provides both fire and carbon monoxide (CO) detection. For fire, the detector combines four separate sensing elements in one unit (smoke, CO, light/flame, and heat) to sense multiple components of a fire. This approach enables enhanced sensitivity to real fire with heightened immunity to nuisance particulate. For CO, the detector's electrochemical sensing cell creates a separate signal for life safety CO detection.

CO is a colorless, odorless, and deadly gas that is virtually impossible to detect with the human senses. It is released whenever carbon- based fuels (from fossil fuels to firewood) burn without enough oxygen to form CO2. Because the potential exists for dangerous levels of CO to accumulate in almost any building, legislation mandating
the use of CO detection in commercial spaces continues to increase across the U.S.The SD355CO is listed to the UL 268 standard for smoke detectors and the UL 2075 standard for system-connected life safety carbon monoxide monitoring.

The SD355CO should be used in conjunction with the B200S intelligent sounder base, which can generate either a Temporal 3 pattern for fire or a Temporal 4 pattern for CO alarm indication. The SD355CO can also be used with the B210LP 6" standard base, the B501 4" standard base, the B224BI base, or the B224RB relay base.

NOTE: The SD355CO is compatible with the ES-50X(C) and ES-200X(C) fire alarm control panels.
