Fire alarms are essential safety devices that can save lives in the event of a fire. However, there may be times when you need to disable a fire alarm, such as when you are testing the alarm or when there is a false alarm. If you need to disable a fire alarm, it is important to do so safely and correctly. In this article, we will provide you with step-by-step instructions on how to disable a fire alarm.
Before you begin, it is important to note that disabling a fire alarm should only be done as a last resort. If there is a fire, you should always evacuate the building immediately. Additionally, you should never disable a fire alarm if you are not sure how to do so safely. If you are unsure, it is best to contact a qualified electrician or fire safety professional.
Once you have determined that it is safe to disable the fire alarm, you can follow these steps:
*
- Identify the fire alarm control panel. This is usually a large, metal box that is mounted on a wall in a central location.
- Open the control panel. There will usually be a key or a combination lock that you will need to use to open the panel.
- Locate the circuit breaker for the fire alarm. This will usually be a small, black switch that is located near the top of the control panel.
- Turn off the circuit breaker. This will disable the power to the fire alarm.
- Close the control panel and lock it.
Disabling the Control Panel
To disable a fire alarm control panel, follow these steps:
- Locate the control panel. It is usually a large, metal box mounted on a wall in a central location.
- Open the control panel door. You may need a key or code to do this.
- Locate the disable switch. It is usually a large, red button or switch.
- Press and hold the disable switch for 10 seconds. The alarm will sound during this time.
- Release the disable switch. The alarm will stop sounding.
- Close the control panel door.
You should only disable a fire alarm control panel if you are authorized to do so and if there is a genuine emergency, such as a fire.
If you are not authorized to disable the control panel, or if there is no emergency, you should contact the fire department or building management.
It is important to note that disabling a fire alarm control panel will only silence the alarm. It will not prevent a fire from occurring or spreading.
| Disable Switch Location | Disable Switch Description |
|---|---|
| Inside the control panel door | Large, red button or switch |
| On the outside of the control panel | Small, red button or switch |
| On a remote control panel | Small, red button or switch |
Cutting the Power Supply
Disabling a fire alarm by cutting the power supply is a simple and quick method, but it should only be performed in situations like false alarms or maintenance activities. To successfully cut the power, follow these steps carefully.
1. Locate the Fire Alarm Control Panel
Locate the fire alarm control panel, which is typically mounted on a wall or in a designated fire safety room. The panel has various controls, including a power switch, buttons, and lights.
2. Identify the Power Switch
Look for the power switch on the control panel. It is usually a red or black switch labeled “Power” or “Main Power.” Ensure that you have positive identification before proceeding.
3. Turn Off the Power
Flip the power switch to the “Off” position. This will cut off the electrical supply to the fire alarm system, including all detectors, strobes, and bells.
4. Wait for Backup Batteries to Deplete
After cutting the power, the fire alarm system’s backup batteries will continue to power the system for a limited period. Wait for the batteries to deplete completely, which usually takes about 15 to 30 minutes. This will ensure that the alarm system is fully disabled and will not reactivate when the power is restored.
| Type of Fire Alarm System | Approximate Battery Depletion Time |
|---|---|
| Addressable Fire Alarm System | 15-20 minutes |
| Conventional Fire Alarm System | 25-30 minutes |
Disconnecting the Wiring
1. Power Off the Circuit Breaker
Locate the circuit breaker that powers the fire alarm system. Flip the breaker to the “Off” position to cut off electricity to the system.
2. Remove the Cover of the Alarm Panel
Unscrew or unclip the cover of the alarm panel to expose the wiring inside.
3. Identify the Wiring Terminals
Look for two terminals labeled “Zone 1” or “Zone 2” (or similar). These terminals connect the alarm panel to the smoke or heat detectors.
4. Disconnect the Wiring
Use a screwdriver to loosen the screws holding the wires in place. Gently pull the wires out of the terminals.
5. Detailed Steps for Disconnecting Wiring:
| Step | Description |
|---|---|
| a. | Wear safety gloves and use insulated tools to prevent electrical shock. |
| b. | Double-check that the circuit breaker is off before touching the wiring. |
| c. | Use a non-conductive tool, such as a plastic screwdriver or lineman’s pliers, to handle the wires. |
| d. | Pull the wires straight out of the terminals to avoid damaging the connections. |
| e. | Label the wires or take photos for future reference when reconnecting. |
Using a Smoke or Heat Detector Cover
In situations where temporarily disabling a fire alarm is necessary, like during cooking or home renovations, using a smoke or heat detector cover can be an effective solution. These covers are designed to fit over the detector head, temporarily blocking it from detecting smoke or heat.
Here’s how to use a smoke or heat detector cover:
1. Locate the fire alarm
Identify the location of the fire alarm that needs to be disabled.
2. Select the appropriate cover
Choose a smoke or heat detector cover that is compatible with the type of detector you have. Covers are typically designed for specific types of detectors, so it’s important to select the right one.
3. Clean the detector head
Before placing the cover, wipe down the detector head with a clean cloth to remove any dust or debris that could interfere with the cover’s effectiveness.
4. Place the cover
Carefully place the cover over the detector head, ensuring it fits snugly and securely. Some covers have magnetic or adhesive attachments, while others simply slide into place.
5. Test the cover
Once the cover is in place, press the “test” button on the alarm to verify that it is no longer detecting smoke or heat. The alarm should not sound when the cover is properly installed.
6. Monitor the situation
While the cover is in place, it’s important to monitor the situation closely. Keep an eye on any potential sources of smoke or heat, such as cooking appliances or burning candles. If smoke or heat is detected, remove the cover immediately and allow the alarm to sound.
