KEEP CLEAR! Gate may move at any me without
prior warning.
Do not let children operate the gate or play in
the gate area.

NOTICE: HySecurity swing gates are equipped with a Type A inherent entrapment sensor (IES) that complies with
UL 325. Any impediment to gate travel causes the gate to stop and reverse.
Monitored external entrapment protection sensors, which can be used in this site scenario and are compatible with
HySecurity swing gates, appear in the following chart. *For a full list, refer to page 6.

A minimum of one monitored external entrapment protection sensor, in addition to the swing gate operator’s inherent
sensor, is required before enabling momentary control activation. Installers may decide both the type and location of the
one required entrapment protection sensor to protect either the open direction, the close direction or both directions of
swing gate travel. However, if there is a risk of entrapment in both directions of gate travel, then both directions of travel
must be protected by an external sensor.
NOTE: If a photo eye open is the only external entrapment protection sensor connected to a swing gate, it's application will require
a constant push button hold close for the swing gate to operate. HySecurity gate operators detect NC output sensors and monitor
them to comply with UL 325 Standard of Safety. Understand that UL 325 conveys the minimum standard of safety. Installers must
assess each specic gate design and site and install external entrapment protection sensors to guard all potential entrapment zones.
* If gate does not accommodate 2" wraparound edge
sensor, two standard channel mount edge sensors may
need to be used.
NOTE: If the bottom edge of a swing gate is greater than 6 inches (152 mm) above the ground at
any point in its arc of travel, one or more contact sensors shall be located on the bottom edge.
