For detailed wirin instructions and setup, select your specific application from the followin available modes, and
continue to the pa e number indicated next to the section title.
Section V – 2, 3, or 4-Door Interlock “A” Setup - Go To Pages 5 & 6
All doors are normally closed and unlocked. Openin any door causes the other doors to lock until the opened door returns to its
normal state.
Section VI – 2, 3, or 4-Door Mantrap “B” Setup – Go To Pages 7 & 8
All doors are normally closed and locked. Each door may be individually unlocked usin the Access Control System or a remote
release. Unlockin any door causes the other doors to be incapable of bein unlocked until the unlocked door returns to its normal
state.
Section VII – 2, 3, or 4-Door Interlock “C” Setup – Go To Pages 9 & 10
All doors are normally closed. Up to three (3) doors may be normally locked, and the remainin door(s) will be normally unlocked.
The possible confi urations are:
2 Doors: Door 1 – Locked, Door 2 – Unlocked
3 Doors: Door 1 – Locked, Doors 2 & 3 – Unlocked
Doors 1 & 2 – Locked, Door 3 – Unlocked
4 Doors: Door 1 – Locked, Doors 2, 3, & 4 – Unlocked
Doors 1 & 2 – Locked, Doors 3 & 4 – Unlocked
Doors 1, 2, & 3 – Locked, Door 4 – Unlocked
Normally Locked doors may be unlocked usin the Access Control System. Unlockin or openin any door will lock the unlocked
doors, and make the locked doors incapable of bein unlocked, until the unlocked/opened door returns to its normal state.
Section VIII – Dual Relay Control Mode – Go To Pages 11 & 12
In Dual Relay Control Mode, the UR4-8 operates as four (4) individually controlled relay stations. Each station provides:
(1) Fused, SPDT lock output, wet or dry,
(1) Non-fused, SPDT auxiliary (monitorin ) output, wet or dry, and
(2) Dry tri er inputs
Activatin each station’s Input 1 OR Input 2 will tri er the correspondin lock output AND the monitorin output simultaneously.
Each Output Station may be confi ured as one of the followin (Input 1 = CR/Input 2 = CR, Input 1 = TD/ Input 2 = CR (TD reset),
Input 1 = CR (LR reset)/Input 2 = LR, or Input 1 = TD/Input 2 = LR)
As a conventional relay (CR), the lock output relay is only activated while the tri er input is activated. Once the tri er input is
released, the output relay returns to its restin state. The monitorin relay output follows the lock output relay.
As a time delayed relay (TD), the lock output relay is activated by the tri er input. Once the tri er input is released, the output
remains activated for a specified period of time, as confi ured by the dip switches. The monitorin relay output follows the lock output
relay.
As a latchin relay (LR), the lock output relay is activated by tri er Input 2. A sin le activation and release of tri er Input 2 latches
the lock output relay. The lock output relay remains latched until tri er Input 2 is reactivated or until the Input 1 is momentarily
activated. The monitorin relay output relay follows the lock output relay.

IV. Applications (Continued)
Section IX – Single Relay Control Mode – Go To Pages 13 & 14
In Sin le Relay Control Mode, the UR4-8 operates as ei ht (8) individually controlled relay stations.
Stations A1, B1, C1, & D1 each provide:
(1) Fused, SPDT lock output, wet or dry and
(1) Dry tri er input
Stations A2, B2, C2, & D2 each provide:
(1) Non-fused, SPDT lock output, wet or dry and
(1) Dry tri er input
Each input may be individually confi ured to operate as a conventional relay or a time delayed relay.
Alternatively, each input may be individually confi ured to operate as a latchin relay or a time delayed relay.
As a conventional relay (CR), the lock output relay is only activated while the tri er input is activated. Once the tri er input is
released, the output relay returns to its restin state.
As a time delayed relay (TD), the lock output relay is activated by the tri er input. Once the tri er input is released, the output
remains activated for a specified period of time, as confi ured by the dip switches.
As a latchin relay (LR), the lock output relay is activated by the tri er Input. A sin le activation and release of the latchin tri er
input latches the lock output relay. The lock output relay remains latched until the latchin tri er input is reactivated.

V. 2, 3, or 4-Door Interlock “A” Setup
Follow the installation steps below before applyin power to the UR4-8.
Refer to the INTERLOCK “A” MODE wirin dia ram on Page 6.
NOTE: It is assumed that the UR4-8 and lockin hardware share the
same power supply.
Interlock “A” Standard Operation:
All doors are normally closed and unlocked. Openin any door causes
the other doors to lock until the opened door returns to its normal state.
Step 1 – Set Dip Switches
The dip switch settin s below are an example of the typical Interlock A
setup shown on Pa e 6. Adjust dip switches SW2-5 & SW2-7 as needed.
All other dip switches should remain as shown below.
Step 2 – Configure the Relay Outputs to be Wet
(Voltage) or Dry.
Use the red WET/DRY Selection Jumpers to confi ure each output.
Refer to Pa e 2 of this instruction for selection procedure.
On the typical Interlock A wirin dia ram, the Lock Relays (Outputs 1, 3,
5, & 7) are confi ured to be wet outputs.
The Monitorin Relays (Outputs 2, 4, 6, & 8) are dry.
NOTE: It is recommended that any unused relays be confi ured as dry
outputs.
Step 3 – Ter inate the Lock Power Wiring
Follow the typical Interlock A wirin dia ram for fail-safe or fail-secure
locks. Be careful to observe lock volta e polarity.
* WARNING!: The UR board Relay Outputs must be protected a ainst
inductive kickback enerated when power is removed from an inductive
load (e. ., electric strikes). Refer to the lock manufacturer's installation
manual or contact the manufacturer for kickback protection
recommendations.
NOTE: All low volta e wirin shall be 18- au e minimum. The minimum
lock power wire au e shall be determined by the SDC wire au e chart.
Si nal wire shall be 22- ua e minimum.
Step 4. Ter inate the Door Monitoring Inputs
Connect the Door Monitorin Switches to Input terminals A1, B1, C1, &
D1. This is a required connection for all door stations bein used.
Door Monitorin inputs (typically Door Position Switches), should be dry,
Normally Open or Normally Closed switches, dependin on the
confi uration of Dip Switch 2-5 (Step 1).
NOTE: Dip Switch 2-5 confi ures the normal state of the Door Monitorin
input when the door is in a CLOSED position. If Normally Closed inputs
are selected, all unused inputs will need to be shorted.
Step 5. Ter inate Auxiliary Inputs and Outputs
(Optional)
Auxiliary Inputs – These inputs must be wired as dry, Normally Open
switches. The input will only be active when closed (shorted). Refer to
Pa e 2 for input descriptions.
Monitorin Relay Outputs – Each door station provides a non-fused,
SPDT monitorin relay. This output may be used to si nal a Security
Panel or to activate a Remote Annunciator. The relay is confi urable as a
Wet or Dry output (Step 2). The relay activation will follow the Lock Relay
or follow the Door Monitorin Input, dependin on the confi uration of Dip
Switch 2-7 (Step 1).
Step 6. Connect a 12 or 24VDC Power Source to the
UR4-8 Controller.
Before applyin power, verify that all the connections are securely
terminated by gently pulling on each wire.
Terminate the volta e wirin to the Controller Power Input, as shown on
Pa e 6. 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 Door Monitorin Inputs by observin the Status
Li hts located on the lower ri ht of the UR4-8 controller.
Status Li hts A1, B1, C1, & D1 will be OFF if Dip Switch 2-5 = OFF, or
will be ON if Dip Switch 2-5 = ON.
Test the standard operation of the interlock by openin any door. All
other doors will lock until the unlocked door returns to its normal state
(closed).

VI. 2, 3, or 4-Door Mantrap “B” Setup
Follow the installation steps below before applyin power to the UR4-8.
Refer to the MANTRA “B” MODE wirin dia ram on Page 8.
NOTE: It is assumed that the UR4-8 and lockin hardware share the
same power supply.
Mantrap “B” Standard Operation:
All doors are normally closed and locked. Each door may be individually
unlocked usin the Access Control System or a remote release.
Unlockin any door causes the other doors to be incapable of bein
unlocked until the unlocked door returns to its normal state.
The door unlock time will be determined by the Access Control System
and by Dip Switches 2-1 throu h 2-4 (See Step 1).
Step 1 – Set Dip Switches
The dip switch settin s below are an example of the typical Mantrap B
setup shown on Pa e 8. Adjust dip switches SW2-1 thru SW2-7 as

Step 2 – Configure the Relay Outputs to be Wet
(Voltage) or Dry.
Use the red WET/DRY Selection Jumpers to confi ure each output.
Refer to Pa e 2 of this instruction for selection procedure.
On the typical Mantrap B wirin dia ram, the Lock Relays (Outputs 1, 3,
5, & 7) are confi ured to be wet outputs.
The Monitorin Relays (Outputs 2, 4, 6, & 8) are dry.
NOTE: It is recommended that any unused relays be confi ured as dry
outputs.
Step 3. Ter inate the Lock Power Wiring
Follow the typical Mantrap B wirin dia ram for fail-safe or fail-secure
locks. Be careful to observe lock volta e polarity.
* WARNING!: The UR board Relay Outputs must be protected a ainst
inductive kickback enerated when power is removed from an inductive
load (e. ., electric strikes). Refer to the lock manufacturer's installation
manual or contact the manufacturer for kickback protection
recommendations.
NOTE: All low volta e wirin shall be 18- au e minimum. The minimum

Door Monitorin and Access Control inputs should be dry, Normally Open
or Normally Closed switches, dependin on the confi uration of Dip
Switches 2-5 and 2-6, respectively.
NOTE: Dip Switch 2-5 confi ures the normal state of the Door Monitorin
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. Ter inate 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
Pa e 2 for input descriptions.
Monitorin Relay Outputs – Each door station provides a non-fused,
SPDT monitorin relay. This output may be used to si nal a Security
Panel or to activate a Remote Annunciator. The relay is confi urable as a
Wet or Dry output (Step 2). The relay activation will follow the Lock Relay
or follow the Door Monitorin Input, dependin on the confi uration of Dip
Switch 2-7 (Step 1).
Step 6. Connect a 12 or 24VDC Power Source to the
UR4-8 Controller.
Before applyin power, verify that all the connections are securely
terminated by gently pulling on each wire.
Terminate the volta e wirin 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.

VII. 2, 3, or 4-Door Interlock “C” Setup
Follow the installation steps below before applyin power to the UR4-8.
Refer to the INTERLOCK “C” MODE wirin dia ram on Page 10.
NOTE: It is assumed that the UR4-8 and lockin hardware share the
same power supply.
Interlock “C” Standard Operation:
Refer to Page 3 – Section VII for method of operation.
Step 1 – Set Dip Switches
The dip switch settin s below are an example of a typical Interlock “C”
setup as shown on Pa e 10.
A) Use dip switches SW1-1 thru SW1-4 to select the Interlock “C” mode
B) Adjust dip switches SW2-1 thru SW2-7 as needed. All other dip
switches should remain as shown below.
Step 2 – Configure the Relay Outputs to be Wet
(Voltage) or Dry.
Use the red WET/DRY Selection Jumpers to confi ure each output.
Refer to Pa e 2 of this instruction for selection procedure.
On the typical Interlock C wirin dia ram, the Lock Relays (Outputs 1, 3,
5, & 7) are confi ured to be wet outputs. The Monitorin Relays (Outputs
2, 4, 6, & 8) are dry.
NOTE: It is recommended that any unused relays be confi ured as dry
outputs.
Step 3. Ter inate the Lock Power Wiring
Follow the typical Interlock “C” wirin dia ram for fail-safe or fail-secure
locks. Be careful to observe lock volta e polarity.
* WARNING!: The UR board Relay Outputs must be protected a ainst
inductive kickback enerated when power is removed from an inductive
load (e. ., electric strikes). Refer to the lock manufacturer's installation
manual or contact the manufacturer for kickback protection
recommendations.
NOTE: All low volta e wirin shall be 18- au e minimum. The minimum
lock power wire au e shall be determined by the SDC wire au e chart.
Si nal wire shall be 22- ua e minimum.
Step 4. Ter inate the Access Control and Door
Monitoring Inputs
NOTE: The Interlock “C” wirin dia ram is shown confi ured for a 4-door
system (3 normally locked doors, and 1 normally unlocked door).
Connect the Door Monitorin Switches to input terminals A1, B1, C1, &
D1. This is a required connection for all door stations bein used.
Connect Access Control or remote releases to input terminals A2, B2, C2,
& D2. This connection is ONLY required for normally locked doors.
Door Monitorin and Access Control inputs should be dry, Normally Open
or Normally Closed switches, dependin on the confi uration of Dip
Switches 2-5 and 2-6, respectively.
NOTE: Dip Switch 2-5 confi ures the normal state of the Door Monitorin
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. Ter inate 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
Pa e 2 for input descriptions.
Monitorin Relay Outputs – Each door station provides a non-fused,
SPDT monitorin relay. This output may be used to si nal a Security
Panel or to activate a Remote Annunciator. The relay is confi urable as a
Wet or Dry output (Step 2). The relay activation will follow the Lock Relay
or follow the Door Monitorin Input, dependin on the confi uration of Dip
Switch 2-7 (Step 1).
Step 6. Connect a 12 or 24VDC Power Source to the
UR4-8 Controller.
Before applyin power, verify that all the connections are securely
terminated by gently pulling on each wire.
Terminate the volta e wirin 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 Monitorin Inputs by
observin the Status Li hts located on the lower ri ht of the UR4-8
controller.
Status Li hts A1, B1, C1, & D1 will be OFF if Dip Switch 2-5 = OFF, or
will be ON if Dip Switch 2-5 = ON.
Status Li hts 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 unlockin any door or by
openin the unlocked door(s). All other doors will be incapable of bein
opened/unlocked until the opened door returns to its normal state.

Set as shown on
Pa e 13, Step 1

X. 2-Door Co unicating Bath Syste
Setup (Single or Dual)
Follow the installation steps below before applyin power to the UR4-8.
Standard Operation:
Refer to Page 4 – Section IX for method of operation.
Refer to the 2-Door Communicating Bath System wirin dia ram on
Page 16.
It is assumed that the UR4-8 and locks will share the same power supply.
Step 1 – Set Dip Switches
The dip switch settin s for a 2-Door Communicatin Bath System must be
set as shown below. Adjust SW1-7 as required.
Step 2 – Configure the Relay Outputs to be Wet
(Voltage) or Dry.
Use the red WET/DRY Selection Jumpers to confi ure each output.
Refer to Pa e 2 of this instruction for selection procedure.
For a Single Comm nicating Bath System:
Outputs 1, 2, 3, & 4 are confi ured to be wet outputs.
Outputs 5, 6, 7, & 8 are confi ured as dry outputs.
For D al Comm nicating Bath Systems:
All outputs are confi ured to be wet outputs.
The relay output volta e will be the same as the UR4-8 input volta e (12
or 24 VDC).
Step 3. Ter inate the Activation and E ergency
Unlock Buttons
For each system, connect the (2) Emer ency Unlock buttons and (1)
Activation button as shown on the Communicatin Bath system wirin
dia ram.
All button switches are wired Normally Open.
Lamp volta e is not polarity sensitive.
NOTE: All low volta e wirin shall be 18- au e minimum. The minimum
lock power wire au e shall be determined by the SDC wire au e chart.
Si nal wire shall be 22- ua e minimum.
Step 4. Ter inate the Lock Power and Lock
Monitoring Options
Select your specific lock type below. Follow the typical Communicatin
Bath system wirin dia ram. Be careful to observe lock volta e polarity.
* WARNING!: The UR board Relay Outputs must be protected a ainst
inductive kickback enerated when power is removed from an inductive
load (e. ., electric strikes). Refer to the lock manufacturer's installation
manual or contact the manufacturer for kickback protection
recommendations.
NOTE: All lock monitorin options below (LBM, DPS, and/or REX) shown
wired so that the circuit is OPEN when the doors are CLOSED and
LATCHED.
Using EMLocks®:
Using Fail-safe Uni-FLEX™ Electric Strikes:
Using Fail-safe Selectric® Pro Locks:
Step 6. Connect a 12 or 24VDC Power Source to the
UR4-8 Controller.
Before applyin power, verify that all the connections are securely
terminated by gently pulling on each wire.
Terminate the volta e wirin to the Controller Power Input. Be careful to
observe polarity.
Verify that both doors are closed & apply power to the controller.
Step 7. UR4-8 Controller Startup and Operation
Verification.
Verify the polarity of the inputs by observin the Status Li hts located on
the lower ri ht of the controller.
With the system at rest, Status Li hts A1, A2, B1, B2, & C1 should all be
turned off.
Test the standard operation of the Communicatin Bath System as
described on Pa e 4.
