GE Security 449AT, Self-Diagnostic Photoelectric 4-Wire Smoke Detector w/ Heat Sensor

The 449AT is a 4- wire self-diagnostic photoelectric smoke detector with heat sensor from GE Security that is designed to promote high sensitivity to heat and smoke to allow for it to easily signal when a fire outbreak has occurred. The 449AT smoke detector comes with a low profile design, an optical field-replaceable chamber, intelligent self diagnostics, as well as a plug-in terminal block, advanced false alarm immunity, and a test and hush feature. The 449AT smoke detector also features an on-site maintenance alert, a white colored appearance, a 6.1” detector head diameter, plus a 1.85” detector head depth, and a 135.0 °F fixed heat detection rate. This smoke detector provides a reliable means to helping keep an environment safe, and provides a reliable signal and warning when the fire has been detected.
