Compatibility
The UL 325 standard requires that a gate edge
sensor be laboratory tested and "recognized"
under UL 325. In order to be compatible with all
HySecurity operators, a gate edge sensor must be
rated to function from 24 VDC source power. For
a list of compatible sensors, refer to page 19.
Installation
HySecurity gates monitor normally closed (NC)
sensors. Wire the NC sensors to SENSOR input
terminals (SENSOR 1, SENSOR 2, or SENSOR 3)
on the Smart DC Controller and set the Installer
Menu item S1, S2, or S3 to the appropriate setting
for the area being monitored.
When using wired edge sensors, the wired edge
must be connected to an interface module with
an NC output. These edge sensors have a 10k Ω
resistor that connects to an interface module. The
interface module (Hy2NC) provides the NC output
for monitoring purposes. Refer to Figure 75 and
Figure 76. For wireless edge sensors, no interface
module is required. Wireless edge sensors need
the wireless gate links which include a transmitter
and receiver. HySecurity has created kits for all-
inclusive shipment.
Gate Edge Function
If the gate is stationary, a tripped gate edge sensor
will prevent the gate from starting programmed
direction. If tripped while in motion, the standard
function is to stop the gate movement and, if
tripped while closing, automatically re-open fully.
An optional setting in the Installer Menu (GR,
Gate Edge Logic) will cause a 2 second reversal if
triggered while closing. Refer to"Table 12. Smart
DC Controller - Installer Menu Functions" on page
68 for more information.

INSTALLING GATE SENSORS ON SWING
GATES
Three-sided sensors are ideal for swing gates. If
gate clearance is 4 inches (10 cm) or more above
the pavement, then an edge sensor must be
mounted on the bottom edge. Drill holes through
the edge sensor's mounting channel and through
the gate surface where each edge sensor is to be
mounted. Securely fasten each edge sensor.
Edge sensors may be used with an edge transmitter
and a receiver in order to transmit to the gate
operator. The use of retractable cord reels or
curl cords is not recommended because of
durability problems with these devices in outdoor
environments.
EDGE SENSOR INSTALLATION TIPS
Refer to page 21 to help plan the most
appropriate placement of the edge sensors being
installed.
z If edge sensors are used sliding gates, one or
SWINGSMART DC PROGRAMMING AND OPERATIONS MANUAL
more contact sensors (edge sensors) must be
located at the leading edge, trailing edge and
post-mounted both inside and outside of the
sliding gate.
• Three-sided detectors are ideal for slide
gates.
• If the clearance of the gate is 6" (15cm) or
more above the road, then an edge sensor
must be mounted on the bottom edge.
• If gate is sliding open to a wall with less than
16" (41cm) of clearance, mount an edge sensor
to wall that aligns with gate in open position.
• Always route leads from edge sensors to
gate operator so that they are protected from
physical damage.
• Underwriters Laboratories requires that any
contact sensor used as an external entrapment
protection device, must be laboratory tested
to, and recognized to the UL 325 Standard.
