しめてなる火災監視装置の動作試験回路。Each fire detection line of a fire monitoring system consists of a large number of fire detection lines to which fire detectors are connected, and a fire detection circuit that detects a fire based on the resistance of each fire detection line and drives an alarm means. In an operation test circuit where a load can be freely connected to check fire detection operation, and a test indicator lamp is lit to indicate that an operation test is in progress, fire detection during operation check is performed based on the voltage across the pseudo load. An operation test circuit for a fire monitoring device, which includes a sub-fire detection circuit that detects the operation of a fire detector connected to the line, and turns off the test indicator lamp when a fire detection signal is obtained from the sub-fire detection circuit. .
