system sensors 400 series plug-in smoke detectors are designed to meet the performance criteria designated by ul/ulc. the ion units have a sensing chamber sealed from back pressure air fow, dirt, and insects. this chamber is protected by a fne mesh screen which can be cleaned or replaced. additional key features include a recessed mounting option, interchangeable ion, thermal detectors, a vari - ety of mounting bases, and a full line of optional accessories. ionization. all 400 series ionization smoke detectors include a specially designed dual source, dual unipolar detector chamber design which will sense the presence of smoke particles produced by fast combustion as well as slow smoldering fres. this chamber exhibits increased stability, signifcantly reduces nuisance alarms, and provides better performance at higher air velocities. thermal. the 400 series thermal rate-of-rise with fxed heat detector contains a unique dual thermistor heat sensing circuit to provide maximum performance and solid state reliability. the model 5451 is designed to initiate an alarm at 135f and to respond to a temperature increase in excess of 15 per minute. this enables the heat detector to communicate an alarm to the central control panel prior to reaching the static set point for these high rates of rise, providing a timely response to both rapid and slow temperature increases. this model should be used in applications where rapid response is desired and where rapid temperature increases would only be caused by a fre emergency. models available 1451 ionization detector 1451A ionization detector, ulc listed 5451 thermal rate-of-rise product overview ssv120-6 low standby current two visible leds blink in standby and provide a 360 feld 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 removable cover and insect screen for feld cleaning 400 series plug-in smoke detector c o n v e n t i o n a l d e t e c t i o n
