This unit is capable of delivering two kinds of audible message to a potential intruder.  Messages can be recorded directly into the unit’s built-in microphone or an external sound source can be connected to the detector.  The system can discriminate between large and small animals to avoid false alarms.

The area protected can be altered by a simple adjustment and the detector will automatically change from a day-time to a night-time message if required.

When set to sequential message mode the system can automatically change the message on the third occasion that it has been activated within a 30 second period.  For example “Move away from this building” “Move away from this building” “Security staff have been called”.
