Monitored External Entrapment Sensors - HySecurity SwingSmart DC Series Programming And Operations Manual

MONITORED EXTERNAL ENTRAPMENT
SENSORS
As of January 2016, UL325 standard requires gate
operators to monitor the presence of all external
entrapment sensors, including non-contact (Photo
Eyes) and contact (Edge) sensors. For operators
built between January 1st, 2016 and July 31st,
2018 only one external entrapment sensor is
needed to allow automatic operation, but all
potential entrapment zones must be protected
or eliminated. After July 31st, 2018, all Slide gate
operators will need a minimum of 2 external
entrapment sensors (1 open direction and 1 close
direction) installed before automatic operation is
allowed, but all potential entrapment zones must
be protected or eliminated.
HySecurity monitors all external entrapment
sensors connections by looking for NC contacts
connected to input terminals. Smart touch
software cycles power to device and looks for
a time delay from when device powers on to
when the contact closes (sensor input pulled low,
meaning the sensor is not blocked/tripped).
Three programmable sensor inputs are available
for use and must be programmed to a non-zero
number when initial configuration is performed.
The three inputs are labeled Sensor 1, Sensor 2,
and Sensor 3 and are configurable in the installer
menu (S1, S2, or S3) for the following options:
z 1 − Not Used
z 2 − Eye Close
z 3 − Edge Close
z 4 − Eye Open
z 5 − Edge Open
z 6 − Edge Both (Swing Only)
z 7 − Eye Both (Solo Slide Only)

It is the installers responsibility to determine the
number of potential entrapment zones that exist
and program the Sensor inputs according to which
type of external entrapment sensor will be used
to protect each zone. If more than three potential
entrapment zones exist, then site design may be
adjusted to eliminate risks or a Miller Edge MIM-
62 may be used to connect additional sensors.
Potential entrapment zones on a slide gate are
shown in Figure 74 Included in the drawing are
examples of potential external entrapment sensor
mounting/installation locations.
