agency listings 400 series plug-in thermal detectors system sensor 400 series plug-in thermal detectors meet the performance criteria designated by underwriters laboratories. features ? low standby current ? two visible leds blink in standby and provide a 360 field viewing angle ? wide variety of mounting bases with built-in shorting spring ? detector head plugs easily into base ? built-in test switch ? field sensitivity metering of detector to meet the requirements of nfpa 72 ? built-in tamper-resistant feature ? sems screws for easy wiring ? optional recessed mounting the 5451 thermal detector meets the needs for applications where rapid response is vital and rapid temperature increases would only be caused by a fre emergency. this detector contains a unique dual thermistor heat sensing circuit that provides maximum performance and solid-state reliability. it initiates an alarm in response to both rapid rate-of-rise conditions (increases in excess of 15f per minute) and fxed heat (135f). this enables the heat detector to communicate an alarm to the central control panel prior to reaching its fxed set point for high rates of rise, providing a timely response to both rapid and slow temperature increases. additional key features include a recessed mounting option, a variety of mounting bases, and a full line of optional accessories. s2101 ob3ao.ay 7270-1653:104
