How to stop a FireAngel smoke alarm from beeping (mains powered)

If your mains-powered FireAngel smoke or heat alarms have begun chirping or flashing amber, follow our advice to help understand what the cause could be.

If your mains-powered smoke or heat alarm has been chirping, false alarming or making a long occasional beep, follow this troubleshooting guide for assistance.

This guide applies to FireAngel ST-230, WST-230, WHT-230, FP1640W2-R and FP1740W2-R alarms.

Why is my FireAngel alarm beeping?

Why does my FireAngel mains smoke alarm keep going off?

If your alarm is frequently chirping it could be for a number of reasons.

1. Incorrectly attached to baseplate

If correctly attached to the baseplate, your alarm should show a green LED, with a red LED flash every 30-45 seconds. If this is not the case, your alarm may not be fitted correctly. We recommend detaching the alarm from the baseplate and reattaching to stop the beeping. If this does not help, try the following step.

2. Incorrect wireless connection

If your alarms are wirelessly connected, try ‘unlearning’ the alarms and refit. If the alarm is still chirping, remove the faulty alarm/s and seek a replacement, or contact FireAngel’s Customer Support team if your alarms are still in warranty.

If your mains-powered smoke or heat detector is false alarming, first we recommend you clean and dust each alarm to stop a build-up of debris or insect webs from preventing the sensor to work correctly. You can follow steps in this guide here.

Once cleaned and refitted, if your alarm continues to sound and is wirelessly connected to other alarms in your home, ‘unlearn’ each alarm and refit. Wait for the alarm to sound again.

If your alarms are not wirelessly connected or the alarm continues to false sound after unlearning and refitting, remove the alarm which has a red LED flashing rapidly. If your alarms are hardwired linked, remove the suspected chirping alarm and wait to see if false alarm stops.

Seek a replacement for the removed alarm or contact FireAngel’s Customer Support team if your alarms are still in warranty.

Why is my FireAngel alarm flashing amber?

Why does my FireAngel mains smoke alarm keep going off?

If your smoke or heat alarm is flashing an amber LED, sometimes with a chirp, it may be due to your alarm being incorrectly attached to the baseplate. If correctly attached to the baseplate, your alarm should show a green LED flashing regularly, with a red LED flash every 45 seconds. If this is not the case, your alarm is not fitted correctly.

We recommend detaching the alarm from the baseplate and reattaching to stop the beeping. Test your alarm twice. If you hear a set of three beeps, your alarm is now correctly attached to baseplate and should no longer be flashing amber.

If the alarm did not sound or is still flashing amber and/or chirping, seek a replacement for the alarm or contact FireAngel’s Customer Support team if your alarms are still in warranty.

Why are my newly installed FireAngel alarms going into full alarm or making occasional long beeps?

If you have a mix of FireAngel alarms installed and interlinked, this may be the cause of the false alarming, as all alarms will need to be interlinked with other Pro Connected products.

If all alarms are from the same FireAngel range and are all hardwired, we recommend checking the connections and wiring of all alarms. If there are no issues with connection or wiring, please get in touch with our Customer Support team for further support.
