Description
The ESL 521BXT is a 2-wire smoke and heat detector that works with the NetworX Alarm Control Panels. The 521BXT has a photoelectric smoke detector and a fixed temperature and rate-of-rise heat detector. It is a great hardwired life-safety and fire-protection sensor for residential use.
The photoelectric smoke detector uses an internal light to determine whether or not smoke is in the area. Smoke will cause the light to refract, and the sensor will respond to this change. The rate-of-rise sensor responds to temperature increases of 15 degrees Fahrenheit or higher in a single minute. The fixed temperature sensor actives at 135 degrees Fahrenheit or higher. The sensor measures 5 inches in diameter and has a thickness of 2 inches.
