The rate-of-rise function responds to fast, flaming fires and the fixed-temperature function responds when the air near the detector exceeds the alarm point. It is compatible only with the Signature Loop Controller and plugs into a separately ordered Signature Series detector base.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDetection method\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFixed temperature and rate-of-rise (thermistor)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFixed temperature rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e135°F (57.2°C); actual alarm point 129°F to 141°F (53.9°C to 60.6°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRate-of-rise rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15°F per minute\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum spacing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 ft (15.2 m) centers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15.20 to 19.95 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNormal operating current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e51 µA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e68 µA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating environment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e32°F to 100°F (0°C to 38°C), 0-93% RH noncondensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStorage temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-4°F to 140°F (-20°C to 60°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVibration level\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10 to 35 Hz, amplitude 0.01 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh-impact engineering polymer, white\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStatus LED\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBicolor (green\/red)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible detector testers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTestifire 1000, Testifire 2000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAgency listings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUL 521; CAN\/ULC-S530\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eCompatibility and installation notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible only with the Edwards Signature Loop Controller; feature support depends on the control panel.\u003c\/li\u003e\n\u003cli\u003eCompatible bases: SIGA-SB, SIGA-SB4, SIGA-RB, SIGA-RB4, SIGA-IB, SIGA-IB4, SIGA-AB4G, SIGA-AB4GT and SIGA-AB4G-LF.
