Burglar Alarm Installation in Bromley

About burglar alarm installation in Bromley

A professionally installed burglar alarm system protects your property with door and window sensors, motion detectors, and a sounder. Systems range from bell-only (audible deterrent) to fully monitored alarms with a 24/7 Alarm Receiving Centre (ARC) and police response. Installation covers system design, sensor placement, panel programming, and connection to monitoring services if required. A professional installer ensures correct sensor positioning, minimises false alarms, and can provide the URN (Unique Reference Number) needed for police response.

A burglar alarm involves wiring sensors to a central control panel, programming entry/exit routes, and configuring zones and alert behaviour. Wired systems require cable runs through walls and lofts. Even wireless systems need correct sensor placement and signal testing to avoid dead zones. If you want police response, the system must be installed by an NSI or SSAIB-approved company and conform to PD 6662 and BS EN 50131. Many home insurance policies require a professionally installed alarm and will not accept DIY installations. An approved installer ensures your system meets the required standards and is eligible for monitoring and police response.

Regulations & standards

• BS EN 50131 (Alarm Systems — Intrusion and Hold-Up Systems): The European standard for intruder alarm systems, specifying grades 1-4 based on the level of security required. Most residential systems are Grade 2 (low to medium risk). The standard covers detection, signalling, power supply, and false alarm management.
• PD 6662:2017 (Scheme for the Application of European Standards for Intruder and Hold-Up Alarm Systems): The UK companion document to BS EN 50131, specifying how the European standard is applied in the UK. Compliance with PD 6662 is required for systems that will have police response. It mandates the use of sequential confirmation (two separate detectors triggered) before a police response is dispatched.
• NSI and SSAIB Codes of Practice: NSI (National Security Inspectorate) and SSAIB (Security Systems and Alarms Inspection Board) are the two UKAS-accredited inspection bodies for security systems. Installation by an NSI or SSAIB-approved company is required for police response and is often stipulated by insurance companies.
• Police Response — URN Requirements: To receive a police response to alarm activations, the system must be installed to PD 6662 by an NSI or SSAIB-approved company, and a Unique Reference Number (URN) must be obtained from the local police force. Systems without a URN will not receive police attendance.
