III. How Manual Call Points Work

How Manual Call Points Work

Manual call points (MCPs) are essential components in fire alarm systems, allowing individuals to manually trigger an alarm in emergency situations, such as fires. Their primary function is to provide a quick, accessible way for building occupants to raise the alarm if they notice danger before automatic systems activate. Here’s how manual call points work in detail:

1. Activation Mechanism

  • User Activation: The user initiates the alarm by either pressing a button, pushing a lever, or breaking a glass panel on the call point. This action completes the internal circuit, sending a signal to the fire alarm control panel.
    • Break Glass MCPs: The glass is physically broken to reach and press the button behind it.
    • Resettable MCPs: A push or pull action is used, and no glass is broken, making it easily resettable for future use.

2. Signal Transmission

  • Once the manual call point is activated, it sends an electrical signal to the fire alarm control panel. The panel is the heart of the fire detection system, processing inputs from manual call points and other devices like smoke detectors and heat sensors.
  • The signal triggers the control panel to activate the building’s fire alarm system, including visual and audible alarms (such as sirens and flashing lights), alerting everyone in the vicinity to evacuate.

3. Immediate Response

  • Alarm Activation: Upon receiving the signal from the manual call point, the fire alarm control panel immediately sounds the alarm throughout the building. This early warning allows building occupants to begin evacuation while awaiting further emergency instructions.
  • Notification of Emergency Services: In many modern fire alarm systems, the control panel is connected to a central monitoring station or directly to the local fire department. Once the manual call point is triggered, it can automatically send a signal to notify emergency services, prompting a swift response.

4. System Feedback and Monitoring

  • Control Panel Monitoring: The fire alarm control panel monitors the status of all manual call points continuously. If a call point is activated or experiences a fault, the control panel can indicate the specific location of the call point, helping emergency responders locate the problem or fire quickly.
  • Resetting the System: After an emergency or false alarm, the manual call point and fire alarm system must be reset. For resettable call points, this is done by using a key or tool to restore the button or lever to its default position. For break-glass models, the glass needs to be replaced before the call point can be operational again.

5. Role in Fire Safety

  • Manual Override: While smoke detectors and other automatic systems are critical, manual call points provide a manual override, allowing occupants to report a fire even if automatic systems have not yet detected it. This feature is crucial for detecting smaller, early-stage fires or fires in areas not covered by automatic sensors.
  • Simplicity and Accessibility: Manual call points are designed to be easily operated by anyone in an emergency, making them highly reliable. They are installed in visible, accessible locations to ensure that occupants can reach them quickly during a fire.

Manual call points play an indispensable role in fire safety by giving building occupants the ability to manually trigger an alarm in emergencies.
