The TM-30 D photoelectric beam is designed for residential, commercial and industrial use.
The beam includes automatic gain control (AGC) to help compensate for loss of signal caused by fog or heavy rain. This circuitry ensures that, even with 99% of signal lost, the beams will continue to function.
To make installations even easier, you can align the beams by using the built-in laser or by using the buzzer which emits a loud audible signal at correct alignment.
When the beam’s reception level is severely dropped in heavy fog, snow or rain, they often cause unwanted alarm activations. The high quality optical lens reinforces the beam’s strength as well as provide excellent immujnity against these environmental conditions.
Adjustable beam interruption time (ABIT) allows you to adjust the time of a beam breakage to signal an alarm. This is useful if you have small animals constantly passing through, therefore prevening a false alarm.
The external light compensation (ELC) circuit provides excellent tolerance against sunlight, automobile headlights, fluorescent light or mercury light.
Furthermore, it has a choice of 4 difference frequencies to avoid cross-talk between multiple units installed nearby or stacked on each other.
For that extra piece of mind, there is an anti-tamper circuit which triggers if the power is cut or the cap is removed.
