This compact movement sensor has a strong 130 decibel siren and and dry contact alarm output that allows it to be linked to the Deluxe FreezeAlarm when an intruder is detected.

This dry contact alarm output can be used to trigger another type of alarm system or building management system that has the capability to monitor a normally open contact input. https://bitbucket.org/occupancysensor/occupancy-sensor/src/master/ makes use of an Infrared Beam to detect movement as much as 20 feet away.
