A manual call point is a fire alarm device initiated by humans. Its activation needs human intervention, which is different from automatic fire alarm activation such as the ones triggered by heat detectors and smoke detectors. However, it is possible for manual call points to be used together with the automatic detection devices as part of the whole fire alarm control system.

After triggering the manual call point during a fire, how to reset it so that it can be used again? The manual call points of most fire alarm control systems mainly have the following three reset types:

 

The pressing area of the break-glass manual call point adopts the special glass. When a fire occurs, people who discover it will trigger the manual call point by breaking the glass and the manual call point will send a fire signal to the fire alarm control panel. After the fire, the break-glass manual call point will have to be reset by changing its glass.

The second type of manual call point is reset by a reset key. There is usually a small keyhole at the bottom of this type of manual call point. after the fire, people will have to reset the manual call point by putting the reset key into the keyhole and turning it.

The third type of manual call point is reset by a sucker. After triggering it during a fire, this type of manual call point needs a special sucker, normally made of plastic, to reset and therefore get ready for use next time. This reset type of manual call point is a rather old type.

The manual call point should be installed in different locations at regular intervals so that anyone can find one easily when a fire occurs. They can also be installed in different types of infrastructure.
