Claims

[Scope of utility model registration request]

Heat detector 1, smoke detector 2, repeater 3, receiver 4
, a fire alarm with a built-in element that records synthesized sounds with a lot of low frequency sound components from musical instruments such as Japanese drums and tempany through a relay to the receiver output terminal of an automatic fire alarm system consisting of wiring 7 on a voice synchronization board. The sound generator 5 and the speaker 6 are connected by wiring 7,
A fire alarm system for hearing-impaired persons having a structure capable of generating a sound with a frequency of 63 hertz to 1 kilohertz that can be heard by hearing-impaired persons at a sound pressure of 106 decibels or more upon detection of a fire.
