3. 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.
