The design of these detectors emphasizes of installation and field maintenance. 12 or 24 VDC operation Unique optical sensing chamber: Superior signal-to-noise ratio. Built-in signal processing. 3.0% nominal sensitivity. Removable cover for field cleaning. Visible LED (cid:147)blinks(cid:148) in standby, latches on in alarm. Sealed against dirt, insects, and back pressure. Optional built-in 135(cid:176)F (57(cid:176)C) thermal. Three-year limited warranty. Field metering of detector sensitivity. Built-in test capability. Low standby current. Twist-on mounting bracket with tamper option. Designed for direct surface or electrical box mounting. Models available with built-in 85 dBA piezoelectric horn. Insect-resistant screening with 0.020″ (0.508 mm) open- Isolated or integrated operation of thermal available (cer- models). SEMS screws for easy wiring. Meets performance criteria designated by UL 268. Built to withstand air velocities up to 3,000 feet (914.4 per minute without triggering a false alarm. to contribute to life safety, fire protection, and property Photoelectric detectors are recommended areas where smoldering fires are likely to ignite. In ar- where small combustion particles are usually present forklift trucks, cooking stoves, etc., they are less likely ionization detectors to produce false alarms. further information, see System Sensor manual I56- (cid:147)Applications Manual for System Smoke Detectors,(cid:148) provides detailed information on detector spacing, zoning, wiring, and special applications.
