HySecurity UL 325 - Slide Gate Site Assessment Diagram; Approved Sensors for Slide Gate Scenarios

NOTICE: HySecurity slide 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 slide 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 slide gate operator’s inherent
sensor, is required before enabling momentary control activation. 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: At minimum, external entrapment protection sensors must be installed wherever potential for entrapment exists during gate
movement. Note that every site is different. All potential entrapment zones should be protected with contact or non-contact
sensors. HySecurity gate operators detect NC output sensors and monitor them to comply with UL 325 Standard of Safety.
NOTE: This scenario shows a possible conguration with the minimum recommended external entrapment protection sensors.
Other sensor congurations are valid. Each gate site is different. It is the installer's responsibility to assess and protect all
entrapment zones.
