Input/output Description
Related DIP switches, jumpers, and
programming tasks
Backup battery input Input for the 4.8 volt nicad battery pack. In the event of a
power failure, the battery pack temporarily powers the micro-
processor until it can properly shut down.
Before you install the controller, we recom-
mend you charge the backup battery pack in
the controller for at least 48 hours.
Note: When changing batteries, dispose of old batteries in accordance with all federal, state, and local regulations.
Caution: After a power interruption, the backup battery pack may require 48 hours to recharge. If
another power interruption occurs within 48 hours, the controller might lose its programming.
Power input
two (2) terminals
(Polarity does not matter.)
Input for a 12 to 24 volts AC or DC at 0.75 amp power supply.
Caution: To prevent damage and injury, connect the
power supply after all other connections have been
made.
None
Alarm output
NC terminal
NO terminal
COM terminal
Relay output that can be used to signal a security system or
activate an alarm input for an alerting device such as a siren,
bell, or strobe light. This output can switch up to 1 amp at
24 volts AC or DC. This output is triggered by door open too
long (DOTL), tamper, or door forced conditions.
Program the alarm output duration. For
instructions, see the V Series Intelligent Pro-
grammer Software User Manual.
Locking device output
NC terminal
NO terminal
COM terminal
Relay output used to unlock or lock an external locking device.
This output can switch up to 5 amps at 24 volts AC or DC.
To determine which terminals to use, consider how the locking
device should operate when power fails at the controller. Refer
to the appropriate table below based on whether the control-
ler and locking device share one power supply or have two sep-
arate power supplies.
Set the locking device jumper (J1). To deter-
mine which jumper setting to use, consider
how the locking device should operate when
power fails at the controller. Refer to the
appropriate table below based on whether the
controller and locking device share one power
supply or have two separate power supplies.
Reader output
RLED terminal
GLED terminal
SOUND terminal
Output that supplies 10 mA at 5 volts, and provides signals cor-
responding to the V Series Electronic Lock’s green LED, red LED,
and sounder. This output can be connected to the reader and
used to provide visual and/or audio user feedback similar to
the feedback provided by the electronic lock. For a description,
see the V Series Service Manual.
The table below shows the recommended color wiring connec-
tions for the standard readers—the Mercury Security, MR–5
(magnetic stripe card reader), the Essex KTP–71212XX (keypad
reader), and the Motorola ASR603, and the HID MB–5398
(proximity readers).

Set controller DIP switch 1.
Note: For readers with a single two-color
LED, set DIP switch 1 ON. For readers with two
separate LEDs, set DIP switch 1 OFF.
The table below shows the recommended con-
troller DIP switch settings for the standard
readers—the Mercury Security, MR–5, the
Essex KTP–71212XX, the Motorola ASR603, and
the HID MB–5398.

For the Mercury Security, MR–5 (magnetic
stripe card reader), set DIP switch 2 on the
reader itself to OFF.
