Security Systems

A well designed security system offers an effective solution in protecting against a number of scenarios. Many of these systems serve a single purpose but often interface with combined elements such as CCTV, access control, intruder alarms, holdup alarm, social alarms and other building services which are monitored and maintained to offer the most comprehensive protection against the identified risks.


This section gives advice on applying the right technical standards, latest news and updates to ensure you’re fully equipped to understand the complexities when installing these systems.

Applying the right standards

Standards set the benchmarks for good practice, professionalism and help provide assurance to clients and ensure their expectations are met. They also promote a culture that encourages the delivery of high quality services.

Applying the right standards is crucial when carrying out different areas of work; importantly they fulfil obligations under contract but ultimately obligations under Health and Safety and the Electricity at Work Regulations.

When designing, installing, commissioning, testing, inspecting or maintaining security systems, depending on the scope of work, a combination of the most recent edition of the following standards would apply:
