Description
 
The F220-PTH Photoelectric Smoke Detector with Heat Sensor uses the light scatter technique using a pulsed infrared source operating with a gated high-speed photodiode infrared sensor and a symmetrical optical chamber that allows uniform 360 smoke entry while increasing immunity to external light. The heat sensor option enhances the operation of the smoke detector; as a temperature rise is detected, the photoelectric chamber becomes more sensitive. The heat sensor can also initiate an alarm if the ambient temperature exceeds +135F (+57C). Head only; needs base. The F220P Series Detectors are UL Listed, open-area Photoelectric Smoke Detectors designed for use with commercial fire protective signaling systems and household fire warning systems (refer to NFPA 72, The National Fire Alarm Code). These smoke detectors employ the light scatter technique using a pulsed infrared source operating with a gated high-speed photodiode infrared sensor. The symmetry of the optical chamber allows uniform 360 smoke entry while increasing immunity to external light. By utilizing low-current electronic circuitry, the detectors can be connected to a wide range of power source circuits.
