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 Agency Listings S2101 OB3AO.AY 7270-1653:104 The 5451 thermal detector meets the needs for applications where rapid response is vital and rapid temperature increases would only be caused by a fire 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 15°F per minute) and fixed heat (135°F). This enables the heat detector to communicate an alarm to the central control panel prior to reaching its fixed 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. 400 Series Plug-In Smoke Detector Specifications Physical/Operating Specifications Size Weight Operating Temperature Range Humidity Range Construction Alarm Point Smoke Detector Spacing Standby Current Operating Voltage/Alarm Current Mounting Base Selection Guide Base Model Number 3.2˝ (8.1 cm) H; 4.0˝ (10.2 cm) Dia., unflanged base; 6.2˝ (15.7 cm) Dia., flanged base 0.3 lb (136 g) 32°F to 100°F (0°C to 38°C) 10% to 93% RH non-condensing Flame retardant Noryl® plastic 135°F (57.2°C) or 15°F/min rate-of-rise On smooth ceilings (as defined in NFPA 72), spacing of 50 feet (2500 sq ft) may be used.
