VEHICLE DETECTOR
HY8RELAY MODULE OPTION
The Hy8Relay (extended relay module) provides 8
numbered mechanical relays. R3, RELAY 3 LOGIC
through R10, RELAY 10 LOGIC can be accessed
through the Installer Menu. Set the number for the
relay based on the information found in Table 15
.
Wire communication cable connections between
the DUAL GATE ports, at the base of the Smart
DC, and the extended-mechanical relay module.
Refer to illustration "Overview of the Smart DC
.
NOTICE
Several user relays are available for revenue
control. These types of relays start at number 29
and go through 38. Refer to the StrongArmPark
DC Programming and Operations Manual for
more information.

No.
Name
Description
1
Close limit output
Creates an interlock signal to another operator's interlock input, or
simply to indicate that gate is secure or not. Relay is released when
fully-closed limit switch is tripped. Relay is energized when fully-closed
limit is released. (Any open command energizes relay.)
2
Close limit pulse
output
Used in a sequenced system to command a second machine to close.
Generates a brief pulsed output that occurs when close limit is triggered.
3
Open limit output
Indicates gate is at full-open position. Output becomes active when an
open-limit is triggered and deactivates when open-limit is released or
a close command is received. Use this output for a traffic light.
4
Open limit pulse
output
Triggers a sequenced barrier arm gate operator to open. Generates a
brief pulsed-output when open-limit is triggered. An additional pulse is
also generated with any new open command even when gate is already
fully-opened.
5
Warn before/during
operate output
Controls an external warning device. This output is active whenever
internal warn before operate buzzer is sounding but the relay output is
constant on. Activation timing of this relay is controlled by setting User
Menu for Warn Before Operate [bF].
6
Gate Lock output
Controls external solenoid locks or magnetic locks. In both directions of
travel, this output is activated about 7/10ths of a second before operator
starts moving the gate.
7
Gate forced open
output
Activated if gate is forced off closed limit switch and operator is not able
to restore gate to full closed position within four seconds. The buzzer
resets itself in 30 seconds but relay stays active until gate receives a
run command.
8
Gate open too long
output
Activates when gate is open longer than the user-selected period of
time. Adjustable from a 0 second to 135 seconds delay in 15-second
increments.
NOTE:
TL - OPEN TIME ALERT adjustments can be made in Installer
Menu.
