Microwave Sensors D15 Approach Sensor Model: D15WL Freq. B One Way Motion Sensor Wide Pattern The model D15 is a motion sensor designed to trigger the operation of automatic doors. The main diffrence between the D15 and other motion sensors is that the D15 will respond to motion moving in only one direction. This type of sensor when used on doorways with two-way traffic will allow the door to close sooner since it only senses the approaching traffic. This prevents heated and/or air-conditioned air from escaping through doorways which would otherwise remain open longer than neccessary. This model is for doorways that have a double width opening of 72". ********************************************************************************** (We do not proofread any ads submitted by members) |
