4 SYNCHRONISED HIGH POWER INFRARED
- 4 beams are "and-gated", which helps to prevent false alarms from falling leaves and small animals.
- The active infrared transmission is exceptionally strong with a maximum arrival distance ten times greater than the specified protection distance.
- External light compensation circuit provides excellent tolerance against sunlight, automobile headlights, fluorescent light or mercury light.
FOUR FREQUENCIES SELECTIONS
- 4 separate frequency choices avoid cross-talk in stacked or long linear installations.
BEAM TRANSMISSION STRENGTH SELECTION
- 2 levels of beam transmission strength can be set to suit the protection distance.
AUTO-GAIN LOCK
- Optimal sensitivity gain is automatically set at any coverage distance up to the maximum protection distance. Auto-Gain lock is easily confirmed by sound check.

EASY BEAM ALIGNMENT
- Audible signal for alignment (Utility model). An alignment tone enables quick set-up of the beams. The tone becomes maximum at peak of beam level.
- Sensitivity attenuation LED lights when beam level is attenuated, which shows low sensitivity.
- Monitor jack output.
PROGRAMMED AGC
- Sensitivity is automatically increased in bad weather to contend with fog, heavy rain, frost or snow.
ALARM MEMORY
- Alarm memory LED located on receiver can be automatically reset (5 mins after alarm, if flickers for 55 mins, then automatically resets) or can be manually controlled.
ENVIRONMENTAL MODULE BUILT-IN
- Environmental trouble signal is sent when beam reception level is reduced below an acceptable level.
- Wide adjustment (horizontally ±90°, vertically ±10°).
- Tamper output.
- Polycarbonate cover excellent at anti-shock.
