Why is Security System Maintenance Important?

Many people believe that security system maintenance is just another business overhead they can ill afford – but what is the potential cost of an intrusion or fire within your business? When installing a system for the sole purpose of protecting your livelihood and staff, it makes sense to ensure it is operational 24/7.

Inclusions / Benefits of a Contract

  • Increased system life span
  • Annual service visit included
  • Engineers availability 24/7
  • Maximum 4 hour response time
  • Reduced engineer call out charges in the event of a system fault
  • Automatic detection of problems (often before the customer even knows!)
  • Support of all equipment, regardless of the manufacturer or original installer
  • Engineer activity report
  • Help desk support
  • Compliance with insurance requirements
  • Keeping staff and property safe
  • Ensuring compliance with legislation & NSI Gold Standards

In the rare event of a problem developing with your system we aim to be on your premises within 4 hours whatever time of day it is and normally a lot faster.

Why Opt For A Security Maintenance Contract?

All police forces stipulate monitored intruder alarms are professionally maintained in order to get police response. This is often required to keep your insurance valid. Security systems under maintenance contracts allow you access to 24/7 engineers and continues to validate your NSI certificate.

On top of this, you have the peace of mind that your business is fully secured 365 days a year and have preferential rates on callouts and replacement equipment.

Have a Non-SDS
Security System?

We are happy to take over or repair systems installed by another company. We will normally send a surveyor to assess the system prior to sending a quotation for the necessary work.

Emergency callouts to non SDS security systems are also provided, however these are dependant on the availability of resources and subject to our higher non-maintained callout rate.
