ABSTRACT:
Two devices for preventing internal combustion of equipment from spreading outwards includes a sampling circuit, a detecting and monitoring circuit, and a low-voltage datum power supply. The sampling circuit includes two thermal detectors. The detecting and monitoring circuit includes a first monitoring output end and a second monitoring output end. When two thermal detectors are both normal, the first monitoring output is inactive and the second monitoring output is inactive. When one of the thermal detectors is abnormal, the first monitoring output is inactive and the second monitoring output is active. When the two thermal detectors are both abnormal, the first monitoring output is active and the second monitoring output is active. The first monitoring output is configured to turn off the power supply of a fan and the second monitoring output is configured to drive an alarm unit.
