About Product

4 SYNCHRONIZED HIGH POWER INFRARED [PATENTED]
*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 sun light, automobile head lights,
fluorescent light or mercury light.
FOUR FREQUENCIES SELECTIONS
4 separate choices of frequency avoids cross-talk in stacked or
long linear installations.
BEAM TRANSMISSION STRENGTH SELECTION
2 levels of beam transmission strength which can be set to suit
the protection distance.
EASY BEAM ALIGNMENT
*Audible signal for alignment [Utillty model]
An alignment tone aids in quick set-up to 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
AUTO-GAIN LOCK
Optimal sensitivity gain is automatically set at any coverage
distance up to the maximum protection distance. Aut-Gain lock
is easily confirmed by sound check.
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 (flickering 5 min. after an alarm and auto-reset 55 min.
after that) or manually controlled.
PROTECTION AGAINST FROST/DEW
As a special hood is attached on sensor
cover, beam protection continues without
interruption even when the cover is screened
by frost or dew.
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 antishock
*Optional accessories
