EXTERNAL ENTRAPMENT PROTECTION SENSORS
External Entrapment Protecon Sensors
Kinec is equipped with a Type A inherent entrapment sensor (IES). UL 325 Safety Standard compliance
requires installaon of external entrapment protecon sensors, the number of which, depends on the
entrapment hazards that exist at each parcular installaon.
To comply with UL 325, the following external sensors may be used:
• Contact sensors, such as edge sensors
• Non-contact sensors, such as photoelectric eyes
The site designer or installer can choose either photoelectric eyes or edge sensors or use these devices in
combinaon. Whatever devices are used, protecon in both the opening and closing direcons of gate
travel must be provided.
The UL 325 Safety Standard for automac sliding gates specically requires that edge sensors or
photoelectric eyes or a combinaon of both devices be installed to protect against pedestrian entrapment
in BOTH direcons of the gate travel and where an entrapment hazard exists.
PHOTOELECTRIC EYES: One or more photoelectric eyes shall be located where the risk of entrapment or
obstrucon exists, such as the perimeter reachable by a moving gate.
A photoelectric eye or contact
sensor is also required to protect
against possible entrapment if the
gate opens to a posion less than
16 inches (40.6cm) from any object,
such as a post or wall.
EDGE SENSORS: One or more edge sensors shall be located on the leading and trailing edges of a slide
gate where the risk of entrapment or obstrucon exists. One or more contact sensors (edge sensors) shall
be located at the leading edge, trailing edge, and post-mounted, both inside and outside of a sliding gate.
SENSOR SECURITY: A hard -wired sensor shall be located and its wiring arranged so that communicaon
between the sensor and gate is not subjected to mechanical damage.
SENSOR FUNCTION and COMMUNICATION: A sensor that transmits its signal to the gate operator must
be located so its signal is not impeded by building structures or other obstrucons. All sensors must be
installed so that they funcon as intended for the end-use condions.
