A brief explaination for the table below follows:
The 'Intruder Threshold' column is the number of false alarms different Police Forces will attend before Police response will be withdrawn.
NB: Some Police Forces state '3un 5conf', this means that Police response will be withdrawn after 3 false alarms for unconfirmed systems (systems installed pre-2002; when the DD243 Standard was introduced) or Police response is withdrawn after 5 false alarms for systems that can give confirmation.
The 'Level 2 - Yes/No' column indicates whether systems unable to give confirmation (& fitted post-DD243) will get a Police response if Police resources are available (Level 1 always takes presedence).
The 'PA Threshold' column indicates how many personal attack false alarms are permitted before Police response is withdrawn.
The 'Combine Intruder/PA - Yes/No' column indicates whether a particular Police Force issues 1 or 2 URNs for Police calling systems that incorporate both personal attack and an intruder alarm.
The 'Warning Letter - 1st/2nd call / 0' column indicates ...
The 'Zeroing/Reduction of false calls' column is for industry use.

LOOK AT INDIVIDUALLY |
* Lancashire is deferring any changes until circa 18 months time when they plan to bring in a new Command and Control.
** Northumbria and PSNI are adopting changes but due to IT demands will be implemented in June 2006.
