The 5601P is the plain-housing member of the family, carrying no exterior alphanumeric marking, which is why System Sensor positions it for residential installations where the lettered models would be visually intrusive. Its rate-of-rise element is restorable so the detector can be field-tested and returned to service, and an external collector drops from the unit on activation to identify which detector is in alarm. A reversible mounting bracket permits both flush and surface mount back box installations.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMechanical heat detector, single circuit, normally open\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eActivation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFixed temperature \/ rate-of-rise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e135°F (57°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRate-of-rise threshold\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15°F (8.3°C) rise per minute\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUL protected spacing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 feet x 50 feet (15.24 m x 15.2 m) on a 10-foot ceiling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExterior identification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNone (plain housing; lettered models are marked FX or FX\/ROR with the rating)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum installation temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100°F (38°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating humidity range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 to 95% RH non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eContact ratings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6–125 VAC \/ 3 A; 6–28 VDC \/ 1 A; 125 VDC \/ 0.3 A; 250 VDC \/ 0.1 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput terminals\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e14–22 AWG, SEMS screws\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions with mounting bracket\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.57 inches (11.6 cm) diameter x 1.69 inches (4.3 cm) height\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6 oz (170 grams)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3½-inch octagonal, 4-inch octagonal, single-gang, or 4-inch square back box with a square-to-round plaster ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eListing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUL 521, Heat Detectors for Fire Protective Signaling Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eInstallation notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProperty protection, not life safety:\u003c\/strong\u003e System Sensor positions the 5600 Series for property protection and non-life-safety installations where smoke detectors are inappropriate.
