A manual call point is a crucial fire safety device that allows individuals to trigger a fire alarm system manually. These devices are typically break-glass or push-button units designed to initiate emergency responses swiftly, ensuring timely action during potential fire hazards. They are essential components in fire safety systems, providing a reliable means to alert others and activate safety protocols.
Definition and Purpose of Manual Call Points
A manual call point (MCP) is a device designed to manually activate a fire alarm system, enabling individuals to quickly alert others in emergency situations. These units, often installed in public or commercial spaces, are typically small, wall-mounted boxes with a button or lever. Their primary purpose is to provide a reliable means of initiating an alarm when a fire is detected, ensuring rapid response and evacuation. MCPs are essential components of fire safety systems, offering a straightforward method for human intervention to trigger alarms and coordinate emergency responses effectively.
Types of Manual Call Points
Manual call points are categorized into two primary types: break glass units and push-button models. Each design ensures rapid activation of fire alarms in emergencies.
Break Glass Units
Break glass units are a common type of manual call point designed for quick activation in emergencies. These devices feature a glass panel that must be broken to activate the alarm, ensuring intentional use and reducing false activations. Typically red in color, they are easily recognizable and accessible. The glass break mechanism is simple yet effective, providing a clear and immediate way to trigger a fire alarm. Once activated, the unit sends a signal to the fire alarm system, alerting others to potential danger. Break glass units are durable, tamper-evident, and designed to withstand accidental triggering, making them a reliable choice for fire safety systems.
Push-Button Models
Push-button models are an alternative to break glass units, offering a straightforward and intuitive method for manual activation. These devices feature a button or lever that must be pressed or pulled to trigger the fire alarm. They are designed for ease of use, providing a clear and deliberate action to initiate an emergency response. Push-button models are often preferred in environments where break glass units may pose a risk, such as schools or public spaces. They are durable, tamper-resistant, and provide immediate feedback, such as a clicking sound or LED indication, to confirm activation. Their simplicity and reliability make them a popular choice in fire safety systems, ensuring quick and effective alerts in emergency situations.
Components of a Manual Call Point
A manual call point consists of a button or lever for activation and internal wiring that connects to the fire alarm system, enabling signal transmission upon activation.
The Button or Lever
The button or lever in a manual call point is the primary interface for activation. Designed for easy use, it typically features a durable construction, often made of materials like plastic or metal. The button or lever is usually red to stand out and may include a protective cover to prevent accidental activation. Once pressed or pulled, it triggers the alarm by completing an electrical circuit. Some models require breaking glass to activate, ensuring intentional use. The design ensures accessibility, allowing anyone to initiate the alarm quickly in an emergency. This component is critical for reliable operation and rapid response to fire threats.
The Wiring and Connectivity
The wiring and connectivity of a manual call point are essential for its functionality.

How Manual Call Points Work
Manual call points activate fire alarms by breaking glass or pressing a button, sending a signal to the fire alarm system to trigger alerts and responses.
Initiating the Fire Alarm
Manual call points initiate fire alarms through physical activation, such as breaking glass or pressing a button, which sends an electrical signal to the fire alarm system. This action triggers the alarm to sound, alerting occupants of a potential fire hazard. The device is designed for quick and easy operation, ensuring rapid response during emergencies. Once activated, the system alerts everyone in the building, enabling timely evacuation and fire response. This straightforward mechanism is critical for fire safety, as it allows individuals to take immediate action when they detect a fire, enhancing overall safety and reducing potential risks.
Signal Transmission to the Fire Alarm System
When a manual call point is activated, it sends an electrical signal to the fire alarm system, indicating a fire emergency. This signal is transmitted through wired or wireless connections, depending on the system’s design; The fire alarm control panel receives the signal and processes it to trigger the alarm. The signal ensures that the alarm sounds throughout the building, notifying occupants of the potential danger. This reliable transmission mechanism is crucial for initiating a prompt response and ensuring safety. The signal’s integrity is maintained through proper installation and regular maintenance, guaranteeing that the fire alarm system operates effectively during emergencies.
Installation and Placement of Manual Call Points
Manual call points are strategically installed in accessible locations, such as corridors, exits, and near elevators, ensuring visibility and ease of use during emergencies.
