Shutter sensor, near-infrared reflective type, indoor shutter, PR-S3

Infrared shutter sensor equipped with alarm memory function.

■Alarm Memory Function When the sensor is triggered, the memory indicator will blink for 3 minutes and then remain lit for 47 minutes due to the built-in timer, allowing you to easily identify which sensor has been activated even if multiple sensors are connected to the same line. ■Highly Reliable Double Beam System Our unique double beam system significantly reduces the effects of shutter rattling, small animals like insects, and reflected light from the shutter surface. It reliably detects forced entry and destruction of the shutter. ■Operation Indicator Output Point With the operation indicator output point, you can confirm the sensor's operation from outside when the sensor is installed inside the shutter roll-up case. ■Cuts Out Radio and Electrical Noise Thanks to our unique circuit and mechanical design, we provide high-level noise resistance. ■Flexible Installation According to the Site The built-in arm allows for easy adjustment of the distance and height between the sensor and the reflective sheet. ■Sensitivity Indicator Light If the sensitivity decreases to a certain level due to dirt on the sensor front or reflective sheet, the sensitivity indicator light will turn on to alert you for maintenance.
