INTRUDER ALARMS Intruder alarms have developed from a very limited specialist element

of electrical installation work in high security buildings to the much

wider market of schools, shops, offices, housing, etc.

This is largely a result of the economics of sophisticated technology

surpassing the efficiency of manual security.

Popular applications include:

Micro-switch, Magnetic reed, Radio sensor, Pressure mat, Taut

wiring, Window strip, Acoustic detector, Vibration, impact or inertia

detector.

Circuit wiring may be `open' or `closed' as shown in principle for fire

alarms

The disadvantage of an open circuit is that if an intruder knows the

whereabouts of cables, the detector circuit can be cut to render the

system inoperative. Cutting a closed circuit will effect the alarm.
