Common Alarm Problems We Fix
A faulty alarm is worse than no alarm at all, because you stop trusting it. We repair burglar alarm systems across Medway, Kent and South East London, whatever the make and whoever fitted it. For Pyronix panels, you can also speak to a Pyronix engineer. These are the faults we are called to most often.
Tamper faults
Tamper warnings on the keypad or app, often after decorating, a knocked sensor or a disturbed cable. We trace the tamper circuit and repair the device or wiring at fault.
False alarms
The alarm activates with nobody there. We check detectors, door contacts and panel settings to find the real cause instead of just resetting the system.
Panel and keypad faults
Dead keypads, panels that will not respond, error codes and systems stuck in an unset state. We diagnose the board, keypad and power supply.
Sensor faults
Movement detectors, door contacts and shock sensors that miss genuine movement or trigger when they should not. We test, reposition or replace them.
Alarm will not set
The system refuses to arm, usually flagging an open zone or a faulty device. We identify the zone, test it and put the fault right.
How a Repair Visit Works
1
Tell us the symptoms
Call 01634 944161 or send a message describing what the system is doing: the fault shown on the keypad, when it started and the make of the panel if you know it. You speak directly to an engineer, not a call centre, and some faults can be talked through on the phone at no charge.
2
We diagnose the fault
On site, the engineer reads the panel's fault log, tests the reported zone or device and traces the wiring where needed. You get a plain explanation of what has failed and what the repair involves before any work starts.
3
Repair and full test
The faulty part is repaired or replaced, then the whole system is tested: every detector walked, every contact checked and the panel confirmed clear of faults. If the repair unearthed anything else worth knowing about, we tell you.
4
Honest advice afterwards
If the system is worth keeping, we say so. If a panel is obsolete and a repair would be money spent on borrowed time, we explain the options and leave the decision with you. No hard sell either way.
For planned upkeep rather than a breakdown, see our alarm servicing and maintenance page. For CCTV faults, see CCTV repairs and maintenance.

Repair or Replace AdviceAlarm Repairs Across Kent & South East London
We provide alarm repairs across the six areas below, generally within around an hour of our Chatham base.
An alarm engineer for breakdowns and existing-system takeovers
A burglar alarm repair should address why protection has stopped working, rather than only remove a message. A keypad warning can originate at a detector, cable, panel or communication path. Tell the alarm engineer what happens when you try to set the system and whether the fault follows a power cut, building work or a change of broadband. That gives the visit a clear starting point without assuming a particular component needs replacing.
We repair systems installed by others and can discuss taking over their maintenance after the breakdown is resolved. Where several faults have accumulated, the useful decision is whether the existing installation can be kept reliable or needs a wider upgrade. We explain the condition and repair options before you agree work. Alarm servicing covers planned upkeep once the system is working, and burglar alarm installation covers a complete replacement where appropriate.
For house alarm repairs near you, provide the location, panel make and exact display message if available. Brand-specific routes include a Texecom alarm engineer, a Pyronix engineer and Visonic alarm repairs. If you have a Yale or another alarm, describe the model so its options can be discussed rather than assuming a particular part is supported. Repairs cover Medway, Kent and South East London from Chatham, generally within around an hour of the base.
