Unique Reference Numbers

Police response to an alarm system can only be given in England and Wales, and possibly soon in Scotland, if a Unique Reference Number (URN) is obtained from the local police force Alarms Administration Department.

To obtain a URN from the local police force, the Alarm Company applying for the URN number must be on the appropriate police force approved list of Intruder Alarm Companies. One stipulation for inclusion on the list is membership of NSI /NACOSS/ICON or SSAIB. (see SEE INSPECTORATE BODIES)

PLEASE NOTE: URN Numbers are not issued to individuals-only listed Security System Installers

An alarm possessing a URN number is referred to as a type ‘A’ alarm system. Alarm companies must conform to certain standards to be considered for inclusion on the police list, including registration with the appropriate certification body e.g. NSI (NACOSS) or the SSAIB, The ACPO 2007 policy must also be adhered to. Any alarm not issued with a URN is very unlikely to receive police response. This type of alarm is described as a type B alarm. Many police forces will not respond to Type B or audible only alarms ringing, unless further on- the- spot confirmation of an offence taking place can be given. This could be a neighbour reporting an intruder entering the premises etc.

The URN is entered on a database in the police communications room, and when an alarm operates, the ARC passes the number to the police communications department, usually via a dedicated telephone line.

This number is entered on a computer and the file for the alarm system is displayed. The file includes names addresses site hazards, site location information etc. needed for a police response. The use of a URN number also enables a record of all alarm calls to be held, to assist in enforcing the ACPO 2007 Security Systems Policy, In respect of false alarms per system. Most police forces charge a fee of about £50-00 including V.A.T for allocating a U.R.N. This is usually a once only fee.
