External Detection Sensors will detect the activity of intruders. In the event of an alarm device being activated a number of events take place:-

The tungsten halogen floodlighting is automatically switched on.

A verbal warning system is activated to drive away the intruders. If they persist in entering further onto the premises a full alarm condition is generated with the siren creating 110 decibels of sound and the strobe light flashing.

When the system has reached "full alarm status" an alarm signal is sent via the signalling device to the Alarm Receiving Centre (ARC).

Upon receipt of the alarm signal the Central Station operator will follow an agreed response plan and contact Keyholders accordingly.
