(3 diggs) Smoke Detector
Context Plus XP95 temperature (heat) detectors have a common profile with ionization and optical smoke detectors but have a low air flow resistance case made of self-extinguishing white polycarbonate. They monitor temperature by using a single thermostat network which provides a voltage output proportional to the external air temperature.
