CHOOSING EXTERNAL ENTRAPMENT PROTECTION
UL 325 LISTING: The edge sensors and photoelectric eyes must be tested and labelled as “Recognized
Components” under UL 325 in order to be deemed acceptable for use in a gate system. Study the safety
instrucons and consider your specic installaon to determine where the greatest entrapment risks exist.
Locate edge sensors and/or photoelectric sensors accordingly.
Be certain that a sucient number of sensors are used so that pedestrians are protected from entrapment
in both direcons of the gate travel and all hazard areas are fully protected. Refer to the UL website at
hps://www.ul.com/ for the most up- to-date list of gate system safety standards (UL 325). Refer to
hps://www.astm.org/ for a complete list of ASTM F2200 Gate and Fence Standards.
Choosing External Entrapment Protecon
The site designer or installer must determine which external entrapment sensor devices will be installed,
in addion to the supplied photo eyes, with the SpeedGate operator to meet UL compliance. The type(s)
of entrapment sensor device systems are described below. For a complete lisng of the requirements, see
UL 325 Safety Standards.
Usage Class Inherent Type Device External Type Device
Class I, II, III A B1, B2, C, or D
Class IV A B1, B2, C, D, or E
To comply with UL 325, refer to the chart and take the following steps:
1. Select the Usage Class according to the gate’s locale and purpose.
2. The required UL 325 inherent Type A sensor is an integral part of the SpeedGate gate system. Based
on the gate’s usage class, choose External Type Devices: B1, B2, C, D, or E.
• To comply using B1 - install non-contact sensors (photoelectric sensor or the equivalent).
• To comply using B2 - install contact sensors (edge sensor device or the equivalent).
• To comply using a Type D device requires a CONSTANT HOLD push-buon staon. This CONSTANT
HOLD push-buon staon must be the only device that opens and closes the gate. It can only be
used where the gate and push-buon staon will be monitored by personnel 24 hours a day in
full view of the gate area. An automac closing device (such as a mer, loop sensor, or similar
SpeedGate is 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.
