Managing false intruder alarms begin by having effective policies and procedures in place to reduce the amount of unwanted or false alarm activations.

Too many unnecessary alarm activations can seriously affect insurance premiums and emergency services’ response. It is essential to ensure your policies and procedures are well communicated and understood by all building occupants.

All intruder alarms that require an instant response upon activation must also request a Unique Reference Number (URN). The URN is how the emergency services determine that your system is suitable for a priority level of response.

Initially, you will receive a level 1 response from the police which makes you a priority response. However, if 3 false alarm activations occur with a 1 year period your property will be demoted to level 3.

Level 3 results in any kind of police response being revoked. If the company can demonstrated that they are trying to resolve the false alarm issues through maintenance or environmental changes the URN scheme will not be withdrawn.


What can activate a security system without there being an intruder?

  • Dust
  • Insects
  • Using incorrect key codes
  • Failure to train authorised users of the system
  • Objects hanging around or in sight of a detector
  • Failure to secure all doors and windows before the alarm has been set
  • Faulty equipment
  • Weak batteries
  • Acts of nature (e.g. strong winds or storms)
  • Human error
