2.
Make an earth ground connection to the cabinet of the controller.
Note:
Follow the requirements of your local electrical code.
3.
Wire the E-GND terminal on the controller printed circuit board directly to the earth ground
connection point.
Connecting door locking devices
WARNING:
Controlled door locks may be governed by regulatory bodies and must always
be installed according to local regulations. In most instances, there are strict limitations to
installing fail-secure devices and fail-safe locking devices such as magnetic locks or other
similar locking devices on doors used as emergency exits.
Note:
The door locking device outputs can operate DC-powered locking devices such as
electromechanical strikes and can be configured to operate in fail-safe or fail-secure mode
(normal or reverse action).
Note:
If required, you can program any of the controller relays to provide galvanically-
isolated outputs.
1.
Connect the negative wire from the door strike to the LK1- output.
2.
Optional:
Connect the door magnetic lock to the LK2- output.
3.
Connect the positive wire to the +12 VDC output.
4.
Program the schedules and access levels for door locking devices.

Callout
Description
A
Door locking device: 12 VDC, 750 mA maximum.
B
Connect a 1000 ohm resistor between LK- and +12 V if you do not use a locking
device.
