Security systems form part of everyday life and are often taken for granted and assumed to be working until something goes wrong, hence the reason why it is important to make sure which ever type of security system installed at your property is maintained properly. Many insurance policies stipulate that electronic security systems are maintained by an NSI accredited company.

Our experienced engineers are trained to check all aspects of the system including power supplies, standby batteries, warning sounders and detection devices to ensure every part of the installation is working correctly and meets the correct standards.

Any system maintained by an accredited National Security Inspectorate company means that a thorough checklist is followed to ensure all aspects of the installed system are checked. Not only this but a regular check by a qualified technician means that any new system requirements or building alterations that may have an effect on the systems areas of coverage can be advised to ensure your system still complies with the latest standards.

Maintenance schedules

One annual visit for audible only systems and two service checks per year for monitored systems in line with PD6662 and BS8243 requirements are carried out.

Although 1 visit a year can be a remote visit, our preference for monitored systems is to visit site on both occasions as we believe this provides a better customer service and minimises time between visits to spot potential problems and provide ongoing advice.

A Tec Fire and Security intruder alarm systems maintenance contract also provides a 4-hour response time, ongoing advice and false alarm management.
