RELAY OUTPUTS – The UR4-8 provides eight (8) individual
SPDT relay outputs.
Outputs 1, 3, 5, & 7 are fused. These outputs are typically
used to power the door locking hardware.
Outputs 2, 4, 6, & 8 are non-fused. These outputs are
typically used as auxiliary (monitoring) relays. They may
be used to power a remote status annunciator, or send a
signal to a security panel.
WET/DRY SELECTION JUMPER – Each relay output may be
configured as a wet (voltage) or dry output. Use the supplied
jumpers to configure each relay individually.
Jumper over top 2 pins = WET
Jumper over bottom 2 pins = DRY
The relay output voltage will be the same as the UR4-8 input
voltage (12 or 24 VDC).
MAIN INPUTS – The UR4-8 provides eight (8) individual
optically isolated inputs. The inputs must be connected to a dry
switch.
These inputs may be collectively configured as Normally Open
or Normally Closed inputs.
NOTE: If Normally Closed inputs are selected, all unused
inputs will need to be shorted.

AUXILIARY INPUTS – The UR4-8 provides four (4) individual
dry, optically isolated auxiliary inputs.
NOTE: These input connections are optional and must be wired
as Normally Open connections. The input will only be active when
closed (shorted).
Input E1 – LOCK ALL – When activated, this input will lock
all the doors, until the input is deactivated. Door Monitoring
Inputs will be ignored.
Input E2 – UNLOCK ALL – When activated, this input will
unlock all the doors, until the input is deactivated. Door
Monitoring Inputs will be ignored.
Input E3– LOCKOUT – When activated, this input will cause
all the lock outputs to remain in their current state, and
ignore changes to the Door Monitoring Inputs. Lock/Unlock
All inputs will also ignored.
Input E4 – EMERGENCY RELEASE (FIRE ALARM) –
When activated, this input will simultaneously release all fail-
safe locks. Door Monitoring Inputs, Lock/Unlock All inputs,
and the Lockout input will be ignored.
INPUT POWER CONNECTION – The UR4-8 must be powered by
a filtered and regulated 12 or 24VDC Power Supply. SDC 600
Series Power Supplies are designed to accommodate and
interface with up to two (2) UR4-8 controllers.
MODE CONFIGURATION DIP SWITCHES – The UR4-8 utilizes
two (2) 8-position dip switch modules for configuring the system
operational modes. They are SW1 and SW2.
STATUS LIGHTS – The UR4-8 provides diagnostic lights to show
the status of each individual input and output on the board.
If an input is closed, its corresponding light
will be ON.
If an output is active, its corresponding light
will be ON.
