Manual call points, also known as manual fire alarm pull stations or manual fire alarm boxes, are devices used to manually initiate a fire alarm in a building or facility. These devices are an essential part of fire detection and notification systems, allowing individuals to quickly alert others about a potential fire emergency. Here’s how they work and operate:
Physical Design: Manual call points are typically wall-mounted devices that consist of a breakable glass cover or a protective hinged lid. Behind the glass or lid is a pull lever or push button. In some cases, the device may also have a sounder or indicator to confirm that the alarm has been activated.
Activation: When a person identifies a fire emergency, they can activate the manual call point by breaking the glass or opening the protective lid and then pulling the lever or pressing the button. This action is designed to be simple and quick so that anyone can activate it without much effort.
Alarm Signal: Once the manual call point is activated, it triggers the fire alarm system. The alarm system typically includes audible and visual alarms, such as sirens, strobe lights, and voice evacuation messages, which alert building occupants about the fire emergency.
Alerting Authorities: In addition to notifying building occupants, the fire alarm system might also be connected to a monitoring center or fire department. When the manual call point is activated, it sends a signal to the monitoring center, allowing them to take appropriate actions and dispatch emergency responders if necessary.
Resetting: After the manual call point has been activated, it needs to be reset to its normal state. This involves replacing the broken glass or closing the protective lid, and in some cases, turning a key or using a special tool to reset the lever or button. The resetting process is typically carried out by authorized personnel or maintenance staff.
Training and Awareness: Proper training is crucial to ensure that individuals understand when and how to use manual call points correctly. People need to be educated about the significance of manual call points and the importance of only activating them in genuine emergency situations.
Maintenance: Manual call points require regular maintenance to ensure they are functional at all times. This involves checking for any damage, ensuring the protective glass or lid is intact, and testing the activation mechanism. Any faults or damage should be addressed promptly to maintain the effectiveness of the fire alarm system.
Manual call points play a vital role in quickly alerting occupants and emergency responders to potential fire emergencies, helping to minimize the risk to life and property. It’s important for building occupants to be familiar with the location of manual call points and to only use them in actual emergency situations.”
