*High-powered surplus capacity, reliable quad active infrared photoelectric detectors, work normally even 99% beam energy is cut.
*Voice indicating the alignment, you can judge the alignment through the voice from buzzer, this is very useful under the high light outdoor environment.
*Traditional alignment debugging from mirror and voltage tests.
*Multi-level LED indicating the alignment, four LED lights, it is visual to understand the alignment, make precise alignment.
*Anti-crawling design, man crawling on the ground and block the lower two beams for 4 seconds, the system will alarm.
*Reliable four beam detecting mode.
*Digital FM pulse infrared source, the capability of anti-jamming is ten times better than common detectors.
*Nami material for cover, prevent moldy, corrosion resistant. Surface not left with water or water marks, not patients. Long-term use in outdoor environments or in cold storage will not led to the decline in performance, even the weather is rainy, humid, frost, ice. Thus it can reduce the need of maintenance.
*EDC circuit has the function of anti-interference from poor environment. EDC circuit can identify the declining of signal, which is caused by changes of environment, such as rain, frog, snow or artificial interference from other infrared sources, under these cases, EDC circuit will output warning (not alarm) signal, remind users of checking detectors or care about environment. The other reason for EDC outputting warning signal is that one group (two beams) is blocked.
*Alarm mode: Only two groups (four beams) are blocked simultaneously, it will alarm. This function is to avoid false alarm caused by pets or leaves.
*Alignment range: Horizontal180.,vertical 20.
*Tamper protection: Activate tamper protection when enclosure removed.
*Black hi-intensity PC for cover avoiding intender destroy and hide detect
