Abstract
A composite fire detector (12) which senses a heat temperature, smoke concentration, and gas concentration due to fire is connected to a transmission path (16) drawn from a fire receiver (10). When a fire test operation is sensed by the fire receiver, a test mode is set to the fire detector. The fire detector performs display control over alarm indicating lights in a mutually varied manner corresponding to each alarm test when a test jig is used to conduct an alarm test by sensing of a heat temperature, an alarm test by sensing of a smoke concentration, and an alarm test by sensing of a gas concentration in a state where the test mode is set. For example, the fire detector repeats one-time blinking of the alarm indicating lights for heat sensing, two-time blinking for smoke sensing, and three-time blinking for gas sensing at intervals of a predetermined nonoperating period.
