Fire alarms.

Fire alarm is used to detect a large amount of smoke, heat, etc., which can produce an alarm when causing a fire, generally set up in the walkway, staircase and other places that are often haunted, when a fire occurs, it can send out a sound alarm, and there is a flashing light to remind the attention of the people present.

Chinese name. Fire alarms.

Body. Fire alarms are generally installed in the walkway.

Peculiarity. Fire alarms are used for fires.

Feature 2: Can be applied to all DC24V electrical.

Fast. Navigation.

Peculiarity. Type.

Fire alarm for fire protection system alarms have two types of coded and non-coded type, coding type that is, an alarm corresponds to an address code, when the host linkage can be a single action or a single action, you can find the corresponding alarm at will; The non-coded type can be sounded when there is electricity, and the fire alarm controller can be accessed through the fire input and output module, and the same area can be controlled by a module.

Fire alarms.

Peculiarity. 1.Fire sirens are used for sound alarm and flash alarm at the fire scene, especially for places where visibility is low or there is smoke at the scene of the accident.

2.It can be applied to all DC24V voltage work fire alarm control system, security monitoring alarm system and other alarm systems, only need to turn on DC24V power supply to work, send out a dazzling flash signal and more than 85dB sound alarm signal.

3.Through the control module, it can be connected to the encoded analog fire alarm control system.

4.Through the intelligent control module, it can be connected to the distributed intelligent fire automatic alarm control system.

5.As an acoustic and visual alarm device in the gas fire extinguishing alarm control system.

6.It has the characteristics of low power consumption, long life, selectable sound and alarm tone, flexible and convenient installation.

If it is a large space, infrared through-beam detectors should be used.
