A retro-reective sensor has the convenience of not requiring the installation and electrical wiring of the remote
emitter required in a thru beam system, but is generally less reliable in poor weather.
NOTE: In an outdoor environment because of reduced performance, avoid using a retro-reective device to span
a distance greater than 24 feet (7.3 meters).
Compatibility
The UL 325 standard requires that a photoelectric sensor be laboratory tested and “recognized” under UL 325.
In order to be compatible with all HySecurity operators, a photo eye must be rated to function from 24 VDC
source power.
Installation
Install additional photo eyes according to the following steps.
1. Locate the photo eye approximately 15 to 30 inches (38 to 76 cm) above the ground and as close to the
gate as possible. Refer to site layout below.
2. Mount the receivers on the left or right side of the gate operator.
3. Mount the emitters just beyond the travel of the gate in the fully-closed position.
NOTE: The installation locations are intended for pedestrian detection. If photo eyes are also to be used for
vehicular detection, consider (in addition to the low elevation photo eye for cars) installing another photo eye
at a height of about 55 inches (140 cm) to detect semi (tractor- trailer) trucks.
