Beeping or Sirens?
If your home alarm keeps beeping it may indicate a fault is present in the system – this will generally cause the alarm code pad to emit a beeping sound. This can happen for a number of reasons such as a power fail or low panel battery. The information in this article will help you determine the cause of the beeping.

Is it Really the Alarm Beeping?
Many other electronic items emit warning beeps. Before blaming the alarm check these two things:
- Check the alarm code pad for any unusual lights or icons
Most alarm will show a fault or service light/icon if there is a problem. Consult the user manual for the meaning of unusual lights/icons
- Press a button on the alarm code pad to test if the tone (sound) emitted is the same as the beeping
Most alarm code pads can only emit one type of tone
If there is no fault light or icon present and the tone emitted by the code pad is different from the beeping, the fault is most likely not coming from the alarm
The most common cause of the beeping if not the alarm is a low battery in a smoke detector. Stand under the smoke detector and check for a flash at the same time as the beeping to determine if this is the cause. If in doubt, change the smoke detector battery anyway.
Other causes of beeping could also be a fridge door not shut properly, cordless phone off hook or not charging, low batteries is toys and gadgets.
It IS the Alarm! What Next?
The alarm system is a complex device with many self-checks and measures. If the home alarm keeps beeping, it is warning of a fault that may damage the device or lessen its effectiveness. Listed below are common reasons for the alarm to beep:
Most modern alarms will display the exact fault after pressing a button sequence on the code pad. Consult the alarm system user manual for this button sequence. This will assist identify the most likely causes if your home alarm keeps beeping.
This will happen if the mains power is switched off in the case of a building wide power fail or accidentally disconnecting the alarm panel power supply
- Do the neighbours have power
- Ensure all circut breakers set to ‘ON’ in the fuse board
- Check the alarm power supply (plug pack) securely fitted and switched on
- Does the power supply feel warm to the touch – if it is cold or excessively hot this could indicate a fault with the power supply. Contact a security technician for further assistance
Low Panel Battery
The backup panel battery over time will cease to hold charge and require replacement. Consult the user manual for the type of battery required.
Low Battery on a Wireless Device
Wireless detectors and devices should have the batteries replaced regularly. Consult the manual for battery types and typical life spans.
If signs of corrosion (green discolouration) or battery leakage are present in the panel or a device remove the battery and dispose of safely. DO NOT return the item to service. Contact an alarm technician.
If the lid of the alarm panel (housing the alarm circuitry) is opened this may trip a box tamper.
- Ensure the panel lid/cover is closed properly and securely
- Enter the code at the code pad to silence the beeps
The external siren has either developed a fault or become disconnected from the alarm panel in some way. Consult an alarm technician for further assistance.
