CHOOSING EXTERNAL ENTRAPMENT PROTECTION
Choosing External Entrapment Protecon
The site designer or installer must determine which external entrapment sensor devices will be installed
with the Kinec operator to meet UL compliance. The type(s) of entrapment sensor device systems are
described below. For a complete lisng 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
The Kinec system 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.
Compliance issues exist with a Type E
device (audible warn before operate
alarm). A Type E device is permied
as a means of external entrapment
protecon by UL 325 in Class IV
applicaons, but it is not recommended
by Wallace Perimeter Security because
a buzzer warns, but cannot protect
against possible entrapment. Wallace
Perimeter Security highly recommends,
even for Class IV use, that external
entrapment protecon (edge or photo-
eye sensor) devices be installed to
detect possible entrapment.
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 Kinec system.
3. 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).
• Refer to the following Secon for the
operator manufacturer’s list of (non-
contact and contact) tested sensors
compliant with the UL 325 Standard of
Safety.
• Mounted beyond 6 feet (183cm) of the
gate, to prevent users from touching or
accessing the gate.
• To comply using a Type D device requires
a CONSTANT HOLD push-buon staon.
This CONSTANT HOLD push-buon
staon must be the only device that
opens and closes the gate. It can only
be used where the gate and push-buon
staon will be monitored by personnel
24 hours a day in full view of the gate
area. An automac closing device (such
as a mer, loop sensor, or similar device)
must not be employed. A Warning
placard stang, “WARNING - Moving
Gate has the Potenal of Inicng
Injury or Death - Do Not Start the Gate
Unless the Path is Clear” must be placed
adjacent to the gate operator control.
