Installing the Universal Relay
Installing the Universal Relay
Follow these steps to install the ADP Universal Relay:
1. Remove the Universal Relay's top cover as shown in the following figure.
a. Using an Allen wrench, remove the two 8-32 security-head screws that
secure the Universal Relay's top cover to its chassis.
b. Lift the top cover off of the Universal Relay's chassis and place it aside.
AC Barrier
Caution
A barrier (shown in the figure above) is installed in the Universal Relay's chassis at
the factory. It is designed to separate the high-voltage, AC portion of the Universal
Relay's circuit board from the low-voltage, DC portion of the board. You must
ensure that this barrier is in place after installing the Universal Relay.
2. The Universal Relay's chassis has four conduit knockouts cut in its case. Using a
pair of needle-nose pliers, remove the necessary number of knockouts.
Generally, you will need to remove only two of these knockouts—one for the
input cable from the ADP timeclock and one for the cable from the AC/DC
device.

3. Two metal cable clamps are supplied with the Universal Relay to provide strain
relief for the cables connected to it. Install these cable clamps in the Universal
Relay's chassis in the locations where you have removed the conduit knockouts.
4. A cable is shipped with each Universal Relay to connect it to a particular model
ADP timeclock. This cable connects to the five-position terminal block
connector (P2) shown in the figure below.

Note
A 9 ft. (2.74 m) cable is shipped with the Universal Relay to connect it to the ADP
timeclock. You should cut this cable to the length required for your particular installation
site. When cutting this cable to length, cut the cable from the end with the flying leads. Do
not cut the cable from the end equipped with the terminal connector.
5. Referring to the following table, connect the supplied timeclock cable to
connector P2 on the Universal Relay. Make only the connections specified for
the particular model ADP timeclock to which you will be connecting the
Universal Relay.

6. Mount the ADP Universal Relay to a wall as follows:
a. Place the Universal Relay level against the mounting surface. Ensure that the
Universal Relay's timeclock’s cable can reach its mating connector on the
ADP timeclock.
b. Using a pen, mark the location of the four mounting holes cut in the Bell
Relay's chassis. The following figure shows the location of these four
mounting holes:

c. Using a power drill and 1/8-inch bit, drill out the marked locations of the
mounting holes. Drill the mounting holes to a depth of approximately 1 inch
(2.54 cm).
d. If you are mounting the Universal Relay to a drywall (sheet rock) surface,
insert a 1-inch plastic screw anchor into each hole.
e.
Place the Universal Relay against the mounting surface and align its
mounting holes over the holes you have drilled.
f. Secure the Universal Relay to the mounting surface using four 1-inch
pan-head #10 wood screws.
7. Connect the other end of the Universal Relay's timeclock cable to the ADP
timeclock as follows:
! When connecting to a 400 Series timeclock, connect to the timeclock’s
Input/Output port labeled TB1. TB1 outputs +5 VDC. Optionally, if the 400
Series timeclock is equipped with an Input/Output Daughter Board
(6600168-001), you can connect the Universal Relay's timeclock cable to
connector TB4. TB4 also outputs +5 VDC.
8. You must tie the Universal Relay's chassis to earth ground (for example;
conduit). The Universal Relay includes a 1.5 ft. (45.72 cm) grounding strap
(3600426-001) and two 3/8-inch hex nuts to tie the chassis to earth ground.
Follow these steps to install the 1.5 ft. (45.72 cm) grounding strap:

Installing the Universal Relay
a. Place one of the provided 3/8-inch hex nuts over the Universal Relay's
ground stud and screw it down until it contacts the chassis. The previous
figure shows the location of this ground stud.
b. Fit the grounding strap's lug over the ground stud and push it down until it
contacts the installed 3/8-inch hex nut.
c. Place the second 3/8-inch hex nut over the ground lug and screw it down
until it contacts the installed grounding strap lug.
d. Connect the other end of the grounding strap to an available earth ground.
Use a short length of 18 AWG (or larger diameter) wire when grounding the
device.
9. Reinstall the Universal Relay's top cover, and secure it using the two provided
8-32 security-head screws.
10. When using the ADP timeclock to control a bell, configure the timeclock as
summarized in the following table.

11. Additionally, when using the ADP 400 Series timeclock to control a bell,
operate the timeclock in Program Mode and configure these operating
parameters:
! Procedure 5, Step 3 - Enable the ADP timeclock to control a bell by
configuring a value of 1 for this parameter. The default value is 0. This
parameter must be set to 1 before command 65 is configurable.
Procedure 20, Step 1 - Specify the number of minutes before each scheduled
bell time that a warning bell is to ring. Valid entries for this parameter are 1
to 30 minutes. The default value is 1.
! Procedure 20, Step 2 - Specify the number seconds that the warning bell is to
ring. Valid entries are 1 to 9 seconds. The default value is 1.
12. When using 400 Series Timeclock to control a door strike, operate the
timeclock in Program Mode and configure these operating parameters:
! Procedure 5, Step 2 - Override repunch restrictions for employees whose
badge numbers are included on the gate list for the ADP timeclock. (No
FIFO record is generated for the second punch.)
! Procedure 5, Step 3 - Configure the ADP timeclock’s output port to support
a Gate.
! Procedure 42, Step 1 - Specify the maximum number of employees to be
downloaded from ADP eTIME software (or other host software) for Gate
List 1.

Connecting an AC/DC Device to the Universal Relay
Connecting an AC/DC Device to the Universal Relay
Note
It is the customer's responsibility to connect the AC or DC device that is to be controlled by
the ADP Universal Relay. This connection should be made only by a licensed electrician
acting in compliance with the National Electrical Code and all local codes.
The Universal Relay is equipped with a four-position screw terminal connector (P1)
that connects the cable from the bell, door strike, or other AC/DC device that is to be
controlled by the ADP timeclock. The following figure shows the location of the
Relay Contact Connector (P1).
Connect cable leads from
AC/DC device here
AC Barrier
One of the Relay Contact Connector's screw terminals is labeled "N." If required,
this terminal may be used as a junction point to which connecting wires from
different cable assemblies are connected. If a high-voltage (115/230 V) AC load is
being controlled, the "N" terminal is provided as a junction point for the load's
unswitched neutral wire.
The Relay Contact Connector's other three screw terminals ("NORMALLY
CLOSED," "COMMON," and "NORMALLY OPEN") connect to the switch
contacts of the Universal Relay's mechanical relay as labeled. Only load voltages
that are within the specifications listed for the mechanical relay's contacts can be
controlled by the Universal Relay (see the section entitled "Specifications"). Only
14 AWG (or smaller diameter) wire must be used to connect to the mechanical
relay's switch contacts.
The figure that follows provides a wiring diagram for the Universal Relay.

Note
If the Universal Relay is used to control a device requiring power to be normally on (and
switched off temporarily by the Universal Relay), then the "SWITCHED HOT" wire shown
above should be connected to the Normally Closed (N.C.) terminal of connector P1.
Caution
It is the customer's responsibility to ensure that any AC device that is connected to
the Universal Relay be equipped with an appropriate disconnect device (i.e., an
appropriate fuse or circuit breaker).
Any device (for example, a bell or door strike) that is connected to the ADP
Universal Relay must be connected to third-wire (earth) ground. The device should
be connected to earth ground from a nearby AC junction box or wall outlet, or the
ADP timeclock’s internal AC outlet (if present). Use a short length of 18 AWG (or
larger diameter) wire when grounding the device.
