APPENDIX B — AVOIDING FALSE ALARMS
False alarms are inconvenient and may give rise to Police response being withdrawn from your
site which may affect your insurance cover.
Here are twelve points to help you avoid false alarms:
1. Ensure that you understand how to operate the alarm system. In your absence the system
should be operated by someone thoroughly instructed in its use.
2. Ensure that:
you know your User Code
your Password is readily available if you need to quote it to the Alarm Receiving
3. Before leaving the premises ensure that all doors and windows are securely closed.
4. Ensure that detection devises such as Infra-red beams or movement detectors are not
obstructed by stock or building partitions.
5. Where Passive Infra-red (PIR) or movement detectors are installed make sure that the area
is kept free from animals and birds. Particular attention should be paid to swinging signs,
fluorescent lights and Christmas decorations. Electric fans, heating or ventilation systems
should, where possible, be switched off before the system is Set.
6. Always follow the setting and unsetting procedure and keep to the entry and exit routes
agreed with the installation engineer.
7. Treat the alarm system with care and ensure that it is not accidentally damaged.
8. Consult your installer about alterations to your building and its contents if you think they
may affect your system or its performance.
9. Always report any obvious reasons for unwanted or false alarms to your installer. If
necessary an engineer will be sent to check the system where it is established that a
technical fault exists.
10. If opening or closing times are monitored by the Alarm Receiving Centre be sure you
notify them of any changes from the agreed times using your password where necessary.
11. While the system should be provided with a stand-by battery for use in the event of an a.c.
mains failure every effort should be made to restore the a.c. mains supply as soon as
12. Make sure that regular maintenance checks are carried on the system to minimise the risk
of technically related false alarms.
