Deactivating the Alarm at the Panel
When the fire alarm sounds, it’s crucial to take action to prevent unnecessary panic and potential hazards. If the alarm is a false alarm or you need to silence it temporarily, you can deactivate it at the panel.
Locate the fire alarm control panel, usually found in a central or accessible location in the building. It may be inside a locked cabinet or behind a protective cover. Once you have access to the panel, follow these steps:
- Identify the emergency stop or silence button. It’s typically a large, red button that requires a firm press.
- Press and hold the emergency stop button for several seconds. The alarm should stop sounding, and the panel may display a message indicating that the alarm has been silenced.
- If the alarm continues to sound after pressing the emergency stop button, check the panel for any additional instructions or contact your local fire department for assistance.
Note: Silencing the alarm at the panel will not reset the system. The alarm will still need to be reset by authorized personnel or after the cause of the alarm has been addressed.
Troubleshooting a Non-Functional Control Switch
If the control switch is not functioning properly, there may be several issues causing the problem. Here are some troubleshooting steps to identify and fix the issue:
