ABSTRACT:
A resettable fire detection device comprises in combination a rate of temperature rise sensor, an electronic fixed temperature sensor, and electronic circuitry connected to both circuits for producing an alarm signal if either sensor is activated and for maintaining the alarm signal once the device has been activated. This resettable fire detection device has many uses: specifically, it can be used as a replacement device for a smoke detector device commonly used on ships. In this case, the device draws a very low amperage for use on a parallel circuit common wih smoke detectors. In addition, a time delay circuit can be associated with each of the sensors to avoid false alarms and to accommodate certain environmental conditions. The resettable nature of both the fixed temperature and rate of rise temperatue sensor allows full testing of each device while allowing a remote reset signal to be used to reset the device. In a preferred form, the rate of temperature rise sensor is a mechanical arrangement.
