Title:
火災報知設備
Document Type and Number:
Japanese Patent JP7132714
Kind Code:
B2
Abstract:
To provide a fire alarm facility capable of performing safe and prompt evacuation guidance by detecting a diffusion state of smoke caused by a fire.SOLUTION: In an R-type fire alarm facility 10, a fire detection signal transmitted from an analog fire sensor 16 installed on a ceiling plane in an alert zone is received by an R-type fire receiver 10, and a fire alarm is outputted. In the analog fire sensor 16, a smoke layer detection part 18 is provided, and a height of a smoke layer generated by a fire is detected and transmitted to the R-type fire receiver 10. In the R-type fire receiver 10, an evacuation guidance control part 36 is provided, and evacuation guidance is generated and reported based on the height of the smoke layer detected by the smoke layer detection part 18. The smoke layer detection part 18 detects the height of the smoke layer in the alert zone in the case of fire due to a millimeter wave radar, a monitoring camera, a ceiling plane temperature and the like.SELECTED DRAWING: Figure 1
