The Firelite SD355T addressable, low-profile plug-in photoelectric detectors use a state-of-the art photoelectric sensing chamber with communications to provide open area protection and are used exclusively with Fire-Lite’s Addressable Fire Alarm Control Panels.
Photoelectric detectors in life-safety applications to provide a broad range of fire-sensing capability, especially where smoldering fires are anticipated. Ionization detectors are often better than photoelectric detectors at sensing fast, flaming fires. Also, Firelite SD355T series plug-in, low-profile smoke detectors designed to commercial standards and offer an attractive appearance.
The addressable photoelectric sensor in the Firelite SD355T series has a unique unipolar chamber that responds quickly as well as uniformly to a broad range of smoke conditions. Additionally, it can withstand wind gusts up to 4,000 feet-per-minute (20 m/sec.) without sending an alarm level signal.
Each Firelite SD355T series detector uses one of 99 possible addresses on the MS-9200UD(LS) and up to 318 (159 on each loop) on the MS-9600UD(LS) Signaling Line Circuit (SLC). Furthermore, it responds to regular polls from the system and reports its type and status.
