Setting Performance Description Wire
Connection
21 Inside Obstruction Vehicle Detector
output
Active whenever Inside Obstruction Vehicle Detector is
tripped.
Relay 1, 2 or 3
22 Center Loop Detector output Active whenever Center (Shadow) loop detector is tripped. Relay 1, 2 or 3
23 External Latching gate Lock Output
(Prison Lock)
Activates when the Lock Interlock Input (Terminal No. 22)
is active at the start of an Open cycle and remains on until
the Lock Interlock releases or 10 seconds elapse, whichever
happens sooner. Also, activates a Close cycle and releases 1
second after reaching the Close limit.
Relay 1, 2 or 3
24 Gate at Partial Open Position Active when partial open position is reached or exceeded. Relay 1, 2 or 3
25 DC Power OK Alert
(Battery OK Alert)
Active when on AC power or the battery voltage is above
21V. When used with User Relay 2, this option can shed
electrical loads to conserve battery energy.
Relay 3
26 Free Exit Vehicle Detector Pulse Activates when the Exit Loop Detector is tripped and causes
a 250mS pulse output to occur.
Relay 1, 2 or 3
27 Not Open (requires AC power) Activated when gate is not on open limit and AC power is
present. Deactivated when AC power fails or gate is on open
limit.
Relay 1, 2 or 3
28 Flasher (requires AC power) Output identical to relay #19 and pulses relay 500 ms/sec
when gate not on open limit and AC power is present.
Deactivated when AC power fails or gate is on open limit.
Relay 1, 2 or 3
29 Set aside for Factory Use HySecurity Testing Only Do not use
30 Arm Break Does not appear. Displayed only used on StrongArm and
StrongArmPark DC and activates if the breakaway arm switch
is tripped.
31 Warn Operate Run Relay is active while warn before and motor running. Relay 1 or 2
32 Partial Open Pulse Relay pulses when partial open activated and when partial
open limit reached. Often used at a sequential gate site.
Relay 1 or 2
33 Outside Obstruction/ Arming Loop
Detector
Activated when OOLD/OALD detector input tripped and
gate closed. Used for testing purposes.
Relay 1 or 2
Hy8Relay Module Option
The Hy8Relay (extended relay module) provides 8
numbered mechanical relays. R 4, RELAY 4 LOGIC
through RB, RELAY 11 LOGIC can be accessed through
the Installer Menu. Set the number for the relay based
on the information found in Table 7: Programmable
User Relays on page 75.
Wire communication cable connections between
the DUAL GATE ports, at the base of the STC, and
the extended mechanical relay module. Refer to
instructions that accompany the Hy8Relay Module.
