  • Interlogix 541NCSXT 4w photo/heat temp sounder

    Designed for connection to an alarm panel that accepts 4-wire fire inputs, the Interlogix ESL 4-Wire Smoke and Heat Detector (with Sounder) integrates reliable, self-diagnostic smoke and heat detection into your security system. As part of the 541 Series, the photoelectric detector features drift compensation and more to enhance performance and reduce false alarms. This model also offers a built-in 85dB audio alarm (sounder). The combination smoke/heat detector offers superior protection compared to standard detectors, because it detects fire in three different ways: smoke detection, fixed heat detection, and rate-of-rise heat detection. Fixed temperature detectors trigger a fire alarm when the ambient temperature reaches a specific temperature. Rate-of-rise detectors trigger an alarm when the ambient temperature quickly rises. Combination detectors, like this unit, use both technologies. The detector uses drift compensation to increase the amount of time between cleanings. Drift compensation automatically adjusts the detector's sensitivity as it gets dirty with time. When the detector finally needs cleaning, you can easily replace its optical chamber and continue relying on the unit without worry. 500 Series smoke detectors work on the photoelectric light-scattering principle.
