All of our intruder alarms are industry-graded installed systems. Our systems will conform to all regulations for most good insurers and meet standards set out by NSI and SSAIB.

Before installation one of our specialist security consultants will complete a site survey and a risk assessment. With this information, we’ll then design a solution to suit your needs and budget. Once you’re happy with our solution we’ll then install it with minimal disruption to your workplace. 

Depending on the system installed servicing is required either annually or every six months. Interested? Contact our Derby and Nottingham sales team today.
