Fixed Temperature Heat Detector EDA-S300 

The detector incorporates a temperature sensitive semiconductor which senses a rise in the ambient temperature and operates at a preset value. Available at 65~C and 75C conforming to the response grades 2 and 3 of BS5445 respectively. For buildings with higher ambient temperatures e.g. boiler houses, detectors are available at l00 C but the radio transmitter should be sited outside the high temperature area. 

In excess of 7 years battery life is achievable from this detector (5 years with combined sounder)
