Analogue Heater Base
– B524HTR

The System Sensor B524HTR is a specialist base in addition to the traditional low profile or deep bases, designed for use with all System Sensor 200 analogue addressable detectors.

The B524HTR Heater Base is a two wire heated base. Designed to be used when environmental conditions mean frost or condensation may build in the detector’s chamber and cause false alarms, it has been designed to raise the temperature of the sensor by a few degrees, thereby preventing problems associated with condensation in the sensing chamber or electronics. The heat delivered through the PCB heats the detector using convection air flows.
