Honeywell ATD-L3R Intelligent Addressable Thermal Heat Detector

The Honeywell ATD-L3R is an addressable thermal detector designed to provide dependable heat detection in commercial fire alarm systems. It combines a 135 degree Fahrenheit fixed temperature threshold with rate of rise detection, allowing the device to respond to both a predetermined high temperature and rapidly increasing temperature conditions.

The ATD-L3R is part of the Velociti Series 3 detector family and features a bright white, low profile housing. Its addressable design allows individual point identification and continuous communication with the fire alarm control panel for reliable system monitoring.
