Planning an intruder alarm system

  • Grade: decide the security grade first. Every panel, detector and contact should meet it.
  • One ecosystem: wireless devices only work with their own radio system, so keep panel and detectors compatible.
  • Layered detection: combine contacts on doors and windows, internal movement detectors and, where needed, external detectors or beams.
  • Signalling: add an external sounder and a communicator for app control or monitoring.

Intruder alarm FAQs

What is the difference between a burglar alarm and an intruder alarm?

In practice there is none. "Intruder alarm" is the term used in standards and by the trade; "burglar alarm" is the everyday name for the same system.

What does an intruder alarm system consist of?

A control panel with keypad or fob control, detection devices such as PIRs and door contacts, a warning device such as an external sounder, and usually a communicator for notifications or monitoring.

Which standard covers intruder alarms in the UK?

Intruder alarm systems are designed to the BS EN 50131 series, applied in the UK through PD 6662, which defines security grades 1 to 4.

What is the difference between a panic button and a hold-up device?

A hold-up device (HUD) is a panic button designed for hold-up alarms, normally with a latching double-push action and a key or code reset. A simple panic button may not meet a hold-up specification, so check what is required.

Does an external siren have to match the alarm panel?

Yes. An external siren must be compatible with the panel, and wireless sirens must use the same radio system. It should also meet the security grade of the installation.
