Heat Detector

2-wire conventional fixed temperature heat detector designed to provide open area protection UL certificated

General Desciption

The 335 series is 2-wire conventional low profile plug-in detectors designed to meet the performance criteria designated by UL. It is a low cost and high reliability series. A LED will be latched on to locally indicate alarm. The in (-) and out (-) terminals are short-circuited inside the detectors. When the detector is mounted, it will continue the wire to the next device or EOL resistor. When it is removed, the wire will be open for wiring supervision.
