- 4 beams are "and-gated", which helps prevent false alarms from falling leaves and small animals.
- 4 separate choices of frequency avoids cross-talk in stacked or long linear installations.
- 2 levels of beam transmission strength which can be set to suit the protection distance.
- Audible signal for alignment. An alignment tone aids in quick set-up to beams. The tone becomes maximum at peak of beam level.
