ESL 449CT Smoke & Heat Detector – 4-Wire, ROR & Fixed Temp, Self-Diagnostic

Description

The ESL 449CT is a state-of-the-art four-wire photoelectric smoke detector that combines reliable smoke detection with integrated fixed temperature and rate-of-rise heat sensing in one compact unit. Designed for both performance and ease of maintenance, it’s ideal for residential, commercial, and light industrial environments.

With advanced self-diagnostics, the ESL 449CT continuously monitors its own sensitivity and operational status, alerting you via a visual indicator if it drifts out of range or fails internal checks.
