5.3 Checklist of points for preventing false alarms
Alarm companies should pass the information given in Annex D and Annex E to clients to aid in the lrevention of operator-related false alarms.
6 Documentation and training
6.1 For each installation, the alarm company should provide the client representative(s) with sufficient written instructions, reinforced by adequate training, to ensure correct operation can be achieved.
6.2 The service department should ensure that each service call following notification of an alarm condition is recorded in an appropriate manner, for example by using a corrective maintenance form, identifying false alarms.
Annex F gives an example of a typical corrective maintenance report form. The completed document should be copied to the client.
It is important that the prime cause (see 6.4) of the false alarm is established and recorded in the corrective maintenance report, as the report forms a source document for the monitoring and categorization of false alarms. The company-wide standard categorization of alarm activations in accordance with Annex G should be used on the corrective maintenance report form.
6.3 Each office at which corrective maintenance call-out requests are received and recorded should have a system in place for monitoring all remotely notified alarm conditions and all other alarm conditions (e.g. local audible) reported to the alarm company.
The monitoring system may be manual or computerized but, as a minimum, it should:
a) form the source document for the identification of troublesome systems and the analysis of recurring defects;
b) in the case of remotely notified I&IIASs, require the ARC to report daily;
NOTE in the case of Saturdays, Sundays and public holidabs, the report may be delayed to the following office day.
c) provide a register of all remotely notified alarm conditions and of all other alarm conditions (e.g. local audible) that have been reported to the alarm company, and discriminate between genuine alarms, false alarms, unconfirmed alarms, and false alerts for monthly analysis.
6.4 In all documentation and reports, the prime cause of the false alarm should be reported, not its effect.
7 Statistics relating to remotely notified I&HAS
An alarm company should compile and collate a record of all remotely notified alarm conditions it receives as follows.
a) Details of all remotely notified alarm conditions should be recorded and categorized as either genuine alarms under several different parameters, unconfirmed alarms, false alarms, or false alerts.
b) Monthly alarm reports should be compiled on an overall company basis, and for each office (see 6.3), including categorization under appropriate categories (see Annex C), so that common problems can be identified.
c) Figures from the monthly reports should be included in a rolling 1 2-monthly log, so that a long-term analysis can be made of unconfirmed alarms, false alarms and false alerts.
d) Company-wide statistics should be compiled, as well as statistics relating to each office. Each office should retain copies of the statistics relating to its own area of responsibility which should be made available for inspection.
e) The SPM should oversee the production of the monthly and rolling 1 2-monthly analyses and ensure that the information is sent to senior executives and others within the alarm company, as appropriate.
