Skip to content Keep your intruder alarm system operating at its best with our expert alarm servicing, one-off call-outs and annual maintenance plans.
If you own a burglar or intruder alarm system — whether recently installed or from another provider — it’s essential to keep it well-maintained to ensure reliable protection for your home or business. At FHA Security, we specialise in alarm servicing and maintenance across all major brands, offering single-visit repairs, full system health-checks and flexible annual service plans. Regular servicing of your alarm system is more than just ticking a box — it’s about safeguarding your property, your insurance cover and your peace of mind. Over time, batteries fail, sensors drift, firmware becomes outdated, and user codes are lost. Left unchecked, these issues can leave even the best alarm system vulnerable.
Whether you have a wired or wireless intruder alarm, home or business system, our alarm service covers:
Full system inspection and health-check
Battery test and replacement of low/expired batteries
Sensor and detector verification (door/window contacts, motion detectors, shock sensors)
Siren, external sounder and control panel testing
User code review, system lockdown/walk-test
