Photo Eye Installation
A monitored connection tests for the presence and correct operation of the photo eyes (and other monitored
sensors) prior to each gate activation. The monitored connection prevents gate operation if an entrapment
protection sensor is missing or any fault is present.
Sensors, such as gate edges and photoelectric beams, must be installed to protect against entrapment. These
external entrapment protection sensors are required for the gate installation to be in compliance with the
2016, UL 325 Standard of Safety (6th Edition).
NOTICE:
UL 325 Standard of Safety provides the MINIMUM safety standards. Site, gate hardware usage,
and other conditions may dictate the use of additional safety designs/components. It is up to the gate system
designer and installer to assess appropriate safety design and components above and beyond minimum UL 325
and ASTM F2200 Standard of Safety. Always check your local area codes and comply with all regulations.
