Burglars dislike noise: it attracts attention. Audible alarms are recommended
over silent alarms and reliable alarms should include:
A battery-powered fail-safe back-up
A rearming capability and siren timer shut-off
Read-out ability to check that the system works
A siren sounding device that can be installed on the exterior of the
home to alert neighbours of possible intrusion.
Some modern alarms will alert a dispatcher at a central office of a
potential threat to your property. The dispatcher can then, in turn,
alert police once he has established that it is not a false alarm. This
type of alarm is usually offered on a monthly or annually subscription
Decals (included with most alarm systems) that advise would-be burglars
of an alarm system on the premises should be placed in highly visible
spots on windows and doors.
