Abstract

The invention discloses a fire alarm system which comprises an alarm device and an acoustical generator and is used for sending out the preset alarm bell in the surveillance area to notify abnormal occurrence. The fire alarm system comprises a mounting base fixed on a preset mounting surface, an alarm device for sensing abnormal occurrences in a surveillance area and an acoustical generator for sending out the preset alarm bell in the surveillance area to notify the abnormal occurrences; wherein the alarm device can be directly fixed on the mounting base, the acoustical generator can be directly fixed on the mounting base too and either the alarm device or acoustical generator can be directly fixed to another alarm device or the acoustical generator fixed on the mounting base.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the filing date of May 10, 2005, the title of the invention being "sounder", and the patent application number being 200580049711.7. technical field [0002] The invention relates to a sounder installed on an alarm device, in particular to a fire alarm system. When the alarm device detects an abnormal phenomenon (such as a fire) and outputs a warning signal, the sounder will The warning signal emits an alarm sound to notify the occurrence of abnormal phenomena. Background technique [0003] In order to protect buildings and people's lives from the threat of fire, an effective method is to install fire detectors to sense the initial generation of fire and issue an alarm. To achieve this purpose, when the fire detector detects a fire in the installed monitoring area, the fire detector will output a warning signal to trigger the alarm bell or the alarm speaker to sound the alarm...
