Replacement is the ESL 541NCRXT Smoke Detector – Call for information 

At Life Safety Consultants, we offer a variety of fire alarm replacement parts like the ESL 449CRT Smoke Detector.  The 449CRT is a UL listed 4-wire 12/24VDC Photoelectric Heat and Smoke Detector with dual fixed temperature and rate-of-rise heat sensor conditions as well as an auxiliary relay.
The 449 series self-diagnostic, 4-wire smoke detectors continually monitor their own sensitivity and operational status, and provide a visual trouble indication if they drift out of sensitivity range or fail internal diagnostics. The detector is easily cleaned by replacing the proprietary field replaceable optical chamber and are designed to reduce false alarms from dust, insects, RFI and external light. An integral combination rate-of-rise and fixed 135 degreesF (57 degreesC), 50-foot rated, heat sensor is available with all “T” model detectors.

This detector is a direct replacement for the 445CR, and 445CRT detectors.

This high-quality detector will ensure your system is always in proper working order, so place your order today and we’ll ship it to you immediately.
