    About this service

    A fault light is not a fire, but it is not nothing

    A fire alarm in fault may not work in part of the building, a system that keeps false alarming gets ignored, and a panel that beeps all night gets switched off. All three leave people less safe than they think.

    Our engineers find the cause, not just the symptom. We read the panel's event log, test the circuits and devices, and tell you plainly what has gone wrong and what it costs to put right. Small faults are often fixed on the first visit; anything larger is quoted at a fixed price first. We repair systems installed by any company.

    Why choose us

    What you get from working with us

    Cause, Not Symptom

    We read the event log and test the circuit, so the fault is fixed rather than silenced until next week.

    Any Make

    Conventional, addressable and wireless systems from the common manufacturers, whoever installed them.

    Fixed Price First

    You know the cost before we do anything beyond finding the fault. No open-ended bills.

    Then Kept in Date

    Once it is working, we can service it every six months so faults are found before they cause a problem.

    Before you call

    Read the panel display and write down the exact message, including any zone or device number. Silence the buzzer at user level, check the logbook and whether anyone has been working near a detector, and make sure the fire alarm isolator has not been switched off. That information helps us bring the right parts. Our guide to fire alarm panel fault messages explains the common ones.

    Do not disable zones or devices to make a fault go away: a disabled zone is part of the building with no fire detection.

    False alarms

    Most false alarms come from a few devices: smoke detectors near kitchens, showers and dusty work areas, and call points that get knocked. We find them from the panel history and fix the cause, usually by changing the detector type or position, and record the change for your fire risk assessment.

    Frequently Asked Questions

    My fire alarm panel is beeping and showing a fault. Is it safe?

    The building is not on fire, but part of the system may not work. Silence the buzzer, note the message, record it in the logbook and get it looked at promptly. If a zone is out of action, the fire risk assessment may require extra measures until it is fixed.

    Do you repair fire alarms installed by other companies?

    Yes. We repair conventional, addressable and wireless systems from the common manufacturers, whoever installed them.

    How much does a fire alarm repair cost?

    It depends on the fault. We find the cause first and give you a fixed price before any repair work. Customers on a servicing contract have faults dealt with as part of their schedule.

    Can you stop our false alarms?

    Usually. Most come from a few devices in the wrong place or of the wrong type. We find them from the panel history, change or move them and record the change.

    Our panel is very old. Can it still be repaired?

    Often, if compatible parts exist. If they do not, we explain the options, from a replacement panel that reuses the wiring to a staged upgrade, with a fixed price for each.
