The LK-25HD/LK-40HD(40m)/LK-60HD(60m)/LK-80HD(80m) are photoelectric intrusion detection systems designed to provide an alarm relay activation upon detection of an intruder through a pair of invisible pulsed infrared beams. The units detect intruders only when both upper and lower beams are simultaneously broken, preventing nuisance alarms due to pets or fallen leaves etc.
Features
- Indoor/outdoor use (wall mount or pole mount)
- Powerful twin beams of pulsed infrared energy to reduce false alarms
- Immunity to infrared interference from sunlight and other light sources
- Blocking time adjustment provided for specific target movement rate detection (50-500msec)
- Tamper protected
