Manual call points, also known as break glass call points or manual fire alarm call points, are crucial components of fire alarm systems. Understanding their function and maintenance is vital for building safety. This comprehensive guide explains everything you need to know about manual call points.

What is a Manual Call Point and How Does it Work?

A manual call point is a simple yet effective device designed to initiate a fire alarm. It's usually a small, red box mounted on walls in strategic locations throughout a building. When activated, it sends a signal to the fire alarm control panel, triggering the alarm.

This activation typically involves breaking a glass cover or pressing a button, depending on the model. The act of breaking the glass or pressing the button completes an electrical circuit, sending the alarm signal. This signal alerts building occupants and the fire service.

Types of Manual Call Points

Manual call points come in various types, each designed for specific needs and environments. Common variations include:

Break Glass Call Points: These traditional call points require breaking a glass cover to activate the alarm. The broken glass acts as a switch, completing the circuit. They are sturdy and reliable.
Push-button Call Points: These modern alternatives use a simple push-button mechanism instead of breaking glass. They are easier to use, less prone to accidental activation, and are often preferred in areas where glass breakage might be problematic.
Weatherproof Call Points: Designed for outdoor use or areas exposed to harsh weather conditions, these call points are sealed and protected against the elements. Their durability ensures consistent performance in various environments.

Where are Manual Call Points Located?

Manual call points are strategically placed throughout a building to ensure quick and easy access in case of fire. Key locations often include:

Corridors and hallways: These are common points of escape, allowing for immediate alarm activation if a fire is discovered.
Stairwells: This is crucial for alerting those evacuating via stairs.
Near exits: Placing them near exits ensures swift activation and facilitates quick evacuation.
Common areas: Places like lobbies, waiting rooms, and gathering spots require call points for swift response.
High-risk areas: Areas with potential fire hazards, like kitchens or workshops, benefit from the placement of additional call points.

The exact placement and number of manual call points depend on building regulations, size, and layout. A fire risk assessment guides the optimal placement strategy.

Maintaining Your Manual Call Points

Regular maintenance and inspection are crucial to ensuring that manual call points function correctly when needed. This includes:

Visual inspection: Check for any signs of damage, tampering, or obstruction. Make sure the call point is securely mounted.
Functionality test: Regularly test the call point to ensure that it sends a signal to the control panel correctly.
Replacement of broken glass: Replace broken glass covers immediately to maintain the system's readiness. Always use approved replacement parts.
Documentation: Keep detailed records of inspections and maintenance activities.

Neglecting maintenance can result in a malfunctioning fire alarm system, potentially endangering lives and property.

Choosing the Right Manual Call Point

The choice of manual call point depends on a number of factors:

Building type: Consider the specific needs and environmental conditions of the building.
Local regulations: Comply with all relevant fire safety regulations and codes.
Budget: Different call point types have varied costs.
Aesthetics: Choose a call point that blends seamlessly with the building's design.

Manual Call Point vs. Automatic Fire Detectors

While manual call points rely on human intervention, automatic fire detectors provide proactive fire detection. Automatic detectors use smoke, heat, or flame sensors to trigger the alarm automatically.

Both manual call points and automatic detectors are complementary parts of a robust fire safety system. They enhance safety by providing multiple avenues for early fire detection and response.

Conclusion

Manual call points are indispensable parts of fire safety systems. Understanding their function, placement, and maintenance is crucial for ensuring effective fire protection. Choosing the right type and implementing a regular maintenance schedule significantly contributes to the safety and security of a building. Don't underestimate the importance of these seemingly simple devices—they could save lives.
