CRYSTAL INFRARED PRESENCE CURTAIN
The Crystal active infrared presence curtain is ideal for threshold safety as well as an activation device when cross
traffic is a concern. It is universally compatible with any door control and easily installed on new doors as well as on
existing doors for retrofit purposes. The Crystal's technology utilizes the process of multiplexing, which assures that
it is constantly scanning the background looking for any changes. Finally if the change in background remains
constant for a set time (adjustable 1 minute or 10 minutes) the sensor learns it and allows your door to return to
normal operation.
For openings narrower than 8' and lower than 13'
