VII. 2, 3, or 4-Door Interlock “C” Setup
Follow the installation steps below before applying power to the UR4-8.
Refer to the INTERLOCK “C” MODE wiring diagram on Page 10.
NOTE: It is assumed that the UR4-8 and locking hardware share the
same power supply.
Interlock “C” Standard Operation:
All doors are normally closed. Up to three (3) doors may be normally
locked, and the remaining door(s) will be normally unlocked. Unlocking or
opening any door will lock the unlocked doors, and make the locked doors
incapable of being unlocked, until the unlocked/opened door returns to its
normal state.
Locked doors are accessed by activating the Access Control System or a
remote release. The door unlock time will be determined by the Access
Control System and by Dip Switches 2-1 through 2-4 (See Step 1).
Step 1 – Set Dip Switches
The dip switch settings below are an example of a typical Interlock “C”
setup as shown on Page 10. Adjust the dip switch settings as needed.
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 Interlock C wiring diagram, the Lock Relays (Outputs 1, 3,
5, & 7) are configured to be wet outputs. The Monitoring Relays (Outputs
2, 4, 6, & 8) are dry.
NOTE: It is recommended that any unused relays be configured as dry
outputs.
Step 3. Terminate the Lock Power Wiring
Follow the typical Interlock “C” 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 Access Control and Door
Monitoring Inputs
NOTE: The Interlock “C” wiring diagram is shown configured for a 4-door
system (3 normally locked doors, and 1 normally unlocked door).
Connect the Door Monitoring Switches to input terminals A1, B1, C1, &
D1. This is a required connection for all door stations being used.
Connect Access Control or remote releases to input terminals A2, B2, C2,
& D2. This connection is ONLY required for normally locked doors.
Door Monitoring and Access Control inputs should be dry, Normally Open
or Normally Closed switches, depending on the configuration of Dip
Switches 2-5 and 2-6, respectively.
NOTE: Dip Switch 2-5 configures the normal state of the Door Monitoring
input when the door is in a CLOSED and/or LOCKED position. If
Normally Closed inputs are used, all unused 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.
Monitoring Relay Outputs – Each door station provides a non-fused,
SPDT monitoring relay. This output may be used to signal a Security
Panel or to activate a Remote Annunciator. The relay is configurable as a
Wet or Dry output (Step 2). The relay activation will follow the Lock Relay
or follow the Door Monitoring Input, depending on the configuration of Dip
Switch 2-7 (Step 1).
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 doors are closed & apply power to the controller.
Step 7. UR4-8 Controller Startup and Operation
Verification.
Verify the polarity of the Access Control & Door Monitoring Inputs by
observing the Status Lights located on the lower right of the UR4-8
controller.
Status Lights A1, B1, C1, & D1 will be OFF if Dip Switch 2-5 = OFF, or
will be ON if Dip Switch 2-5 = ON.
Status Lights A2, B2, & C2 will be OFF if Dip Switch 2-6 = OFF, or will be
ON if Dip Switch 2-6 = ON.
Test the standard operation of the interlock by unlocking any door or by
opening the unlocked door(s). All other doors will be incapable of being
opened/unlocked until the opened door returns to its normal state.
