2.2 Electronic Alarm and Surveillance Systems

2.2.1 Intruder Alarm Systems

There are many good quality alarm systems available on the market – but make sure you purchase one that complies with Australian Standards (AS-2201).

Commercial alarm systems typically use motion or infrared detectors – or a combination of both.

The detectors need to be placed carefully to ensure they pick up intruders at all possible entry points - including from public spaces via suspended ceilings. And it’s best to place the detectors in prominent positions visible through windows and doors as their very presence will deter intruders. (Make sure that desks and partitions will not shield intruders from the detectors.)

By law, alarm systems must stop sounding after a period of time, so it’s a good idea to select a system that incorporates an external flashing light to warn early starters or mobile guards and police that the alarm has been triggered and intruders may still be on the premises.

Back-to-base or monitored alarm systems provide the best level of protection, as there is no guarantee anyone will respond to a sounding alarm only.

Also, make sure your system has adequate battery back-up in case thieves cut the power or there is a black-out, and it can be worthwhile having a GSM cellular back-up unit installed for monitored systems in case the telephone lines are compromised.

Make sure you change the PINs (Personal Identification Numbers) regularly, especially when staff turnover is frequent.
