Alarm repeatedly triggered by a pet moving around the property: what causes it and how it is fixed
Stop pets setting off the burglar alarm. This page covers the causes worth checking on magnetic lock systems, what you can safely check yourself, and what an engineer does on the visit.
- Fault: alarm repeatedly triggered by a pet moving around the property
- System in view: magnetic lock system
- Priority: not an emergency, but worth booking rather than ignoring
Symptom
Event log points to a detector in a room the pet has access to
Check first
Check the weight and size rating printed or documented for the fitted detector type
Likely cause
Pet larger than the detector's rated tolerance
Recognising it
What people are usually trying to solve here: stop pets setting off the burglar alarm.
- Event log points to a detector in a room the pet has access to
- Larger or more active pets trigger it more often
Two things worth trying
If either of these clears the fault, there is no reason to book a visit at all.
- 1Check the weight and size rating printed or documented for the fitted detector type
- 2Note which room and detector consistently show the trigger
Burglar alarm repairs
- Alarm fault finding
- Component replacement
- System health checks
What tends to be behind it
- Pet larger than the detector's rated tolerance
- Pet-immune detectors are usually rated up to a certain weight, and a larger or more energetic animal can exceed that threshold.
- Pet able to climb onto furniture within the detector's field of view
- Even a pet-tolerant detector can be triggered if the animal gets close enough to the sensor by climbing.
Magnetic lock systems: the components in play
Diagnosis on a magnetic lock system follows its own sequence, because the failure points sit elsewhere.
- Door position and lock status monitoring
- Confirms whether the door is actually closed and locked, not just that power is applied.
- Fire alarm interface
- Ensures the lock releases automatically on a fire signal for safe egress.
The repair, step by step
This fault is not an emergency, but worth booking rather than ignoring.
- 1Fit or reposition pet-tolerant detectors correctly for height and coverage angle
- 2Restrict pet access to specific rooms during arming where full detector coverage is not practical
Where a private rental property feels this fault
- Front door under the landlord's maintenance responsibility
- That is the access route that needs to be covered reliably, which is why alarm repeatedly triggered by a pet moving around the property there is worth fixing rather than living with.
- Landlord-approved wireless alarm as an addition, not an alteration
- Many wireless systems can be fitted without drilling or altering fixtures, making landlord approval more straightforward to obtain.
Locally, in Dover
Across the CT16 postcodes, port-area night-time freight traffic, visible deterrent CCTV at residential entrances and gate sensors on side accesses are the standard.
What no amount of spending will fix
They provide no mechanical lock if power is cut deliberately, so they are rarely used alone on a high-security perimeter door. Periodic force testing of the magnet, alignment checks, and confirmation that the fire alarm release interface still functions correctly.
Stopping it coming back
Discuss pet size and habits honestly with whoever configures the system, since detector choice and placement both depend on it.
