SDC UR2-4 - Manual (Page 30)

IX. Single Relay Control Mode Setup
Follow the installation steps below before applying power to the UR4-8.
Refer to the SINGLE RELAY CONTROL MODE wiring diagram on Page
14.
NOTE: It is assumed that the UR4-8 and locks will share the same power
supply.
Standard Operation:
In Single Relay Control Mode, the UR4-8 operates as eight (8) individually
controlled relay stations. Each trigger input controls a single output.
Each input may be individually configured to operate as a conventional
relay (CR) or a time delayed relay (TD).
Alternatively, each input may be individually configured to operate as a
latching relay (LR) or a time delayed relay.
Refer to Page 4 of this instruction for relay operation descriptions.
Step 1 – Set Dip Switches
The dip switch settings below are an example of a typical Single Relay
Control Mode Setup as shown on Page 14. Adjust the dip switch settings
as required.
Use dip switches SW1-1 through SW1-8 to select the operation of each
trigger input: CR, TD, or LR.
If dip switch SW2-6 = OFF, each input is selectable as a CR or TD only.
If dip switch SW2-6 = ON, each input is selectable as a LR or TD only.
Step 2 – Configure the Relay Outputs to be Wet
(Voltage) or Dry.
Use the red WET/DRY Selection Jumpers to configure each output.
Refer to Page 2 of this instruction for selection procedure.
On the typical Single Relay Control Mode wiring diagram, all relay outputs
are configured as wet outputs.
The relay output voltage will be the same as the UR4-8 input voltage (12
or 24 VDC).
NOTE: It is recommended that any unused relays be configured as dry
outputs.
Step 3. Terminate the Lock Power Wiring
Follow the Single Relay Control Mode wiring diagram for fail-safe or fail-
secure locks. Be careful to observe lock voltage polarity.
NOTE: All low voltage wiring shall be 18-gauge minimum. The minimum
lock power wire gauge shall be determined by the SDC wire gauge chart.
Signal wire shall be 22-guage minimum.
Step 4. Terminate the Station Trigger Inputs
Connect each station’s trigger input as required.
All the trigger inputs should be dry, momentary, Normally Open or
Normally Closed switches, depending on the configuration of Dip Switch
2-5 (Step 1).
NOTE: Dip Switch 2-5 configures the normal (resting) state of the trigger
input. If Normally Closed inputs are used, all unused trigger inputs will
need to be shorted.
Step 5. Terminate Optional Inputs and Outputs
Auxiliary Inputs – These inputs must be wired as dry, Normally Open
switches. The input will only be active when closed (shorted). Refer to
Page 2 for input descriptions.
Step 6. Connect a 12 or 24VDC Power Source to the
UR4-8 Controller.
Before applying power, verify that all the connections are securely
terminated by gently pulling on each wire.
Terminate the voltage wiring to the Controller Power Input. Be careful to
observe polarity.
Verify that all the trigger inputs are in their normal (resting) state & apply
power to the controller.
Step 7. UR4-8 Controller Startup and Operation
Verification.
Verify the polarity of each Station trigger input by observing the Status
Lights located on the lower right of the controller.
Status Lights A1, A2, B1, B2, C1, C2, D1 & D2 will be OFF if Dip Switch
2-5 = OFF, or will be ON if Dip Switch 2-5 = ON.
Test the standard operation of each station control relay by momentarily
pressing the trigger input.
In CR mode, the respective door will unlock while the trigger input is
activated, and relock when the trigger is released.
In TD mode, the respective door will unlock when the trigger input is
activated. Releasing the trigger input will start the unlock timer and the
door will remain unlocked. The door will relock after the set unlock time
has expired.
In LR mode, the respective door will unlock when the trigger input is
momentarily activated and released. The door will remained unlocked
indefinitely until the trigger input is reactivated.

SW2-2 ON = 1 0 sec., OFF = 0 sec.;
SW2-3 ON = 20 sec., OFF = 0 sec.;
SW2-4 ON = 30 sec., OFF = 0 sec.;
Switch times are additive. {A ll OFF = 1 sec.; A ll ON = 65
sec.}
