It combines optical (photoelectric) smoke sensing with rate-of-rise heat sensing in one device. As a result, the SIGA-OSHD efficiently detects smoldering fires as well as fast-flaming fires.\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003ch3\u003eEdwards SIGA-OSHD — dual-sensor optical detection\u003c\/h3\u003e\n\u003ch3\u003eFirst, the optical smoke sensor uses dual optical wavelengths combined with multiple detection angles. Then particle data is fed through digital filters with ratio algorithms that reject signal patterns typical of cooking nuisance sources. In addition, the on-board rate-of-rise heat sensor adds a 15°F\/min (9°C\/min) function plus a 135°F (57.2°C) fixed-temperature threshold. Furthermore, both sensors feed the detector microprocessor, which compares readings to preprogrammed settings before initiating an alarm.\u003c\/h3\u003e\n\u003ch3\u003eUL 268 7th Edition listing\u003c\/h3\u003e\n\u003ch3\u003eThe SIGA-OSHD is listed to UL 268 7th edition, the latest smoke detector standard with enhanced cooking-nuisance immunity. Integrated nuisance rejection helps reduce unwanted alarms from general cooking particulates.\u003c\/h3\u003e\n\u003ch3\u003eIntelligent sensing features\u003c\/h3\u003e\n\u003ch3\u003eSmoke sensitivity range: 0.5 to 4.36 %\/ft (1.6 to 13.6 %\/m) obscuration. Five sensitivity settings with automatic day\/night sensitivity adjustment. Also, twenty pre-alarm settings, two levels of environmental compensation, and two levels of dirty-detector warning. Furthermore, the detector supports automatic device mapping and self-diagnostics with history log in non-volatile memory.\u003c\/h3\u003e\n\u003ch3\u003eElectrical and environmental\u003c\/h3\u003e\n\u003ch3\u003eOperating voltage: 15.20 to 19.95 VDC from the Signature loop.
