System Sensor 2151 Ssd Series 100,Photo Duct Head

For use in HVAC duct systems, the System Sensor 2151 Photo Duct Head (SSD Series 100) is a smoke detector. With dimensions of 1.66 inches in height and 6.1 inches in circumference, this low-profile sensor uses photoelectric sensing. A light beam inside the sensor gets blocked when smoke gets into the duct. This notifies residents of a possible fire situation by sounding an alarm signal at a suitable fire alarm control panel. With its broad operating temperature range of 32°F to 120°F and humidity levels of 10% to 93%, the System Sensor 2151 is appropriate for a variety of HVAC settings. Its low standby current (85 µA) further reduces energy usage. An essential function of the System Sensor 2151 Photo Duct Head is to continuously monitor the airflow within ducts.
