The fire alarm bell is an alarm device that can give alarm sounds, reminding people to escape when there is a fire. Once the fire alarm bell can’t sound, people might lose the initial chance to evacuate. Therefore, fire alarm bell needs to be checked and tested regularly to see if they can work properly. If damaged, the fire alarm bell needs to be replaced immediately.

What are the reasons for the fire alarm bell not sounding?

First, we need to figure out how the fire alarm bell works. Take the 24V fire alarm bell as an example. The fire alarm control panel controls the fire control module, providing 24V voltage to the fire alarm bell, and the fire alarm bell gives alarming sounds through the 24V voltage.

Due to the working principle of the fire alarm bell, there are many issues needed to be considered when finding out the reasons why it doesn’t sound. The possible reasons for the fire alarm bell not sounding include:

The fire alarm bell is damaged.
The fire alarm control module is damaged.
The linkage program of the fire alarm control panel is faulty.
The circuit is faulty.

How to find out the reason why the fire alarm bell doesn’t sound?

First, check whether the fire alarm bell is damaged. You can short-circuit the 24V output terminal through the input and output module to see if the fire alarm bell can be triggered.
If the circuit has a 24V voltage output, it is very likely that the fire alarm bell is damaged.
If the fire alarm bell isn’t damaged, but it still can’t be activated when the manual call point is pressed, it is necessary to check whether the input and output modules are still normal and whether the linkage program of the fire alarm control panel is correct.

What is Fire Hose?

Oct .13.2023

A fire hose is a highly pressurized hose that is used to bring water to the fire. It may also transport flame retardants. Fire hoses can be attached to either a fire engine or a fire hydrant, and the pressure is between 800 and 2000 kPa. For reasons of fire safety, it's quite important to have a fire hose inspection as well as all fire protection equipment tested. If, during a fire emergency, the fire hose fails it could have disastrous results.

What is Water-proof Fire Alarm System?

Waterproof Heat Detector
Fixed Temperature Waterproof Heat Detector, the detector uses a bi-metallic strip to sense temperature change, therefore consuming minimal standby current and providing high reliability.
The Detector is particularly suited to environments, which are exposed to high levels of condensation or are hosed down. The detector has a wide operating margin allowing it to respond to both slow and fast increases in temperature; it can also sense temperature reliably in a horizontal or vertical position.
