What Is Manual Call Point In Fire Alarm System

Introduction to Fire Alarm Systems

In the realm of building safety, nothing is more fundamental than the fire alarm system. These systems are an essential part of any building design, as they are designed to detect smoke, heat, and fire, promptly informing building occupants and the local fire department. Despite most people's understanding of the need for a fire alarm system, not many understand the intricacies that go into designing and operating these life-saving systems. Among the various components integral to a fire alarm system is the manual call point, a small but critical device that can help mitigate a fire's damaging effects.

Understanding the Manual Call Point

The manual call point, also known as manual pull station, is a device that initiates an alarm when a user manually activates it. Located strategically across the structure's premises, it is typically a red box marked ‘fire’ that is secured to a wall. It comprises a glass panel, which when broken or pulled in a fire emergency, triggers the fire alarm system to go off.

How does a Manual Call Point Work?

The operation of a manual call point is relatively straightforward. Once the enclosed glass of the manual call point is broken or pulled down, it introduces a switch into the circuits of the fire alarm system. This switch, in turn, signals the fire alarm control panel about the activation, indicating a potential fire hazard. The control panel then triggers an alarm throughout the building via interconnected alarm devices like horn speakers and strobe lights, alerting the building's occupants to evacuate immediately. Simultaneously, the system can notify the local fire department or a monitoring center to allow immediate action to be taken.

Types of Manual Call Points

Manual call points are available in two main types: break glass and push button. A break glass call point requires you to break a thin glass panel to activate the alarm. This type of call point usually includes a small hammer attached to it with the main intention of breaking the glass. It is preferred because, unlike the push button type, it provides physical evidence, leaving no room for accidental activation.

The push button call point, on the other hand, is simply designed with a button that you push to activate the alarm. Some versions need you to lift a transparent protective cover before pressing the button, a feature designed to prevent accidental activation.

The Crucial Role of Manual Call Points in Fire Alarm Systems

The reason manual call points are a fundamental component in a fire alarm system is primarily due to their role in the early recognition of a fire. The time it takes to detect a fire can have a significant impact on reducing damage and loss of life. With manual call points, fire detection does not rely solely on automated systems like smoke detectors. Thus, in the event of a small fire or early stages of a fire where smoke detectors may not have gone off yet, a person can manually trigger the alarm, allowing for early evacuation and fire control measures.

Placement of Manual Call Points

The positioning of manual call points in a building is crucial for maximizing their efficiency. They should be easily visible and accessible to people in the case of emergencies. Regulations generally recommend placing them in areas of high traffic, near exits, at every floor landing in staircases, and at entrances to escape routes. The placement height should typically be about 1.4 meters from the floor for ease of reach.

Maintenance of Manual Call Points

Maintenance of manual call points is essential to ensure they are operational when needed. This process involves checking the call point's visibility and accessibility, ensuring the glass or button is intact, and verifying that it triggers the alarm when activated. These tests should ideally be carried out by certified professionals during the recommended routine fire alarm system checks.

Conclusion

In summation, a manual call point is a vital part of a comprehensive fire alarm system, offering a manual means to alert people to a fire event in a building. It helps facilitate quick detection, timely evacuation, and response to a fire threat, potentially saving lives and property. Like all components of a fire safety system, it requires proper positioning, maintenance, and regular checks to ensure it functions as intended. With greater understanding and appreciation of this device, building owners can better equip their structures for fire emergencies, ultimately bolstering the safety and protection of those within.
