- The below are the most common questions we get asked about Domestic Fire Alarms.
Why is my fire alarm beeping?
Fire alarms can beep for several reasons. The most common ones are:
- Low battery: This is typically indicated by an intermittent beep every few minutes.
- Fault in the system: A constant beep may indicate a fault in the alarm system itself, such as a malfunctioning sensor or electrical issue.
- Test mode: Some alarms beep periodically when they're in a testing mode.
- Smoke or fire detection: Continuous loud beeping usually means the alarm has detected smoke or fire.
- End of life: Some alarms have an end-of-life warning to tell you when the alarm itself needs replacing, often after 10 years.
What does a continuous fire alarm mean?
A continuous fire alarm typically means that the device has detected smoke or fire. This is a safety feature to alert the occupants of the building to evacuate. However, if there is no apparent danger, it could also indicate a malfunction in the device.

How to stop a fire alarm from beeping?
Here's what you can do to stop a fire alarm from beeping:
- If it's a low battery warning, you should replace the battery.
- If the device is malfunctioning, try resetting it. This often involves removing the battery, pressing and holding the test button for around 15 seconds, reinserting the battery and then pressing the test button again.
- If the alarm is hardwired into your electrical system, you may need to try flipping the circuit breaker associated with the alarm.
- If none of these work, you may need to replace the entire device.
How to turn off a fire alarm?
Turning off a fire alarm differs depending on the model and type (battery operated or hardwired). Here's a general approach:
- For battery-operated models, simply remove the battery. Remember to replace it promptly; a fire alarm without a battery is useless in an emergency.
- For hardwired models, you'll usually need to disconnect it from the mains. This often involves turning off the circuit breaker associated with the alarm. However, be aware that doing so will disable the alarm, leaving you unprotected.

How to change a fire alarm battery?
To change a fire alarm battery, follow these steps:
- Firstly, ensure your safety. Use a sturdy step ladder to reach the alarm.
- Remove the alarm from its mounting on the ceiling or wall. There's typically a twist-off mechanism, but it may vary between models.
- Once it's off, you should see a compartment for the battery. Open this, remove the old battery, and replace it with a new one, ensuring the positive/negative terminals align correctly.
- After replacing the battery, put the fire alarm back in its place and test the alarm to ensure it's working.
Please note that the above instructions might vary depending on the make and model of your fire alarm. It's best to consult the user manual or manufacturer's website for specific instructions.
