Addressable Photoelectric Smoke Detector with Fixed Temperature Heat Sensor, 2-Wire Protocol

The Honeywell 5193SDT model is an addressable photoelectric smoke detector that also integrates a restorable fixed-temperature (57°C/135°F) heat detector using electronic thermistors. It is designed for open-area protection in addressable fire detection systems and installs onto a mounting base that can be pre-wired to facilitate placement or removal. Its drift compensation algorithm automatically adjusts sensitivity to compensate for contaminant buildup in the optical chamber and sends a maintenance signal to the panel when its compensation limit is reached. It is used in conjunction with compatible UL-listed Honeywell control panels.

Key features

• Integrated fixed heat sensor that activates at 57°C (135°F) using electronic thermistors
