Manual call point fire alarm system request
Fire alarm push button or MCP, also known as fire alarm push button, manual fire push button or manual contact point fire alarm, is a device that is used to manually activate the fire alarm system in case of fire emergency and usually in the public area. or located near the exit points inside the building. In fact, a manual call point fire alarm is a device for manually initiating an alarm.
Manual activation of the fire alarm is usually achieved using a pull station (term used in the US and Canada) or a contact point (term used in Europe, Australia and Asia). It then sounds the evacuation alarm for the building or area concerned.
Manual fire alarm activation requires human intervention. However, contact points or pull stations can be used with automatic detection as part of a general fire detection and alarm system.

In Europe, Australia, New Zealand and Asia, traction stations are not usually used. Instead, a manual contact point fire alarm is used, commonly referred to as MCP, contact point or fire point in the fire protection industry.
A manual call point fire alarm allows building occupants to signal a fire or other emergency in the building. They are usually connected to a central fire alarm panel which is connected to an alarm system in the building.
A manual contact point fire alarm is used to trigger an alarm signal and is activated by a simple push of a button or when the glass is broken and reveals a button. These systems can form part of a manual warning system or an automatic warning system. There will be a marker on the monitoring unit for visual indication so you can easily find the contact point.

- When the fragile element is replaced, the contact point returns to its normal state.
- The glass should be well secured with sealing rings.
- Manual contact point fire alarms shall be equipped with current limiting resistors permanently installed within the unit and not wired to terminals provided for field wiring.
- Contact point operation shall detect a change in loop current at the fire and gas control panel.

How the manual contact point fire alarm works
Manual call point fire alarm operation is simple and easy. In case of fire or emergency, the user can break the glass or press the dedicated button to activate the alarm. This creates a signal that is transmitted to the fire alarm control panel that initiates evacuation protocols and alerts building occupants.
After the situation is resolved, the manual contact point fire alarm must be reset to its normal state, either manually or automatically, to restore functionality. It is important to note that the exact construction and operation of the manual call point may vary by manufacturer and model. However, the basic functionality remains the same in all devices, allowing manual activation of the fire alarm system if required.
