How Manual Call Points Work
Manual call points operate on a simple yet effective principle, designed to reliably trigger a fire alarm system when activated. The mechanism varies slightly depending on the type of call point, but the fundamental concept remains the same.
In break glass call points, breaking the protective glass cover disconnects an internal switch, completing an electrical circuit. This circuit activation sends a signal to the fire alarm control panel, initiating the alarm sequence. The panel then activates sirens, strobes, and other notification devices, alerting occupants and potentially triggering automatic fire suppression systems.
Push button call points utilize a simple push button mechanism. Pressing the button closes an electrical circuit, sending a signal to the fire alarm control panel. This signal triggers the same alarm sequence as in break glass call points, activating audible and visual alarms and potentially initiating other safety measures.
Dual action call points combine both mechanisms. They often feature a push button for routine testing, allowing for regular system checks, and a break glass element for emergency situations. This dual functionality provides flexibility and adaptability in various applications.
Regardless of the specific mechanism, manual call points play a vital role in fire safety by enabling individuals to quickly alert others to a fire and initiate a coordinated response.
