CX-12 PLUS DOOR INTERFACE RELAY
I NSTA LLAT I O N I N S T RU C T I O N S
Note: Do not wire Safety devices to the CX-12. If installed,
wire your safety device directly to the operator control box
as per usual.
IMPORTANT: Do not apply power to the unit until all
secondary wiring is complete, and dip switches have been set.
Both relay outputs are Form C and are rated at 3 amps maximum.
Use relay # 1 for the strike or electromagnet. Generally, the N.O. &
COM. Terminals (#3 & 4) are used for a strike, and COM & N.C. (#4 &
5) are used with an electromagnet. The door operator will be wired
to relay #2 N.O. & COM terminals (#6 & 7). In a door sequencing
application, door 1 is relay #1, and door 2 is relay #2. The unit will
operate on 12 or 24 volts, AC or DC. Connect to Terminals 1 & 2,
which are non-polarity sensitive.
4. APPLICATIONS & SET-UP INSTRUCTIONS

Standard Timer Mode

Set dip switches as shown. Also refer to Diagram 1.
Connect a dry contact such as a wall switch to DRY1 (Terminals
11 & 12). A Wet (powered) output connects to WET 2 (Terminals
13 & 14).Upon a switch activation the strike relay will fire for the
time set by potentiometer 1 (DOR RL1). After a delay, adjustable
by potentiometer 2 (DOO RL2), the operator relay will fire. The
hold time for relay #2 is set with potentiometer 2 (DOR RL2).
Most modern door operators have built-in time delays, and
if so, it is usually desirable to use them to add sufficient hold-
open time. In this case adjust the CX-12 PLUS to send just a
momentary pulse (1 or 2 seconds only). Observe the door and
adjust timers until desired operation is observed.
The above dip switch setting is also used for applications
such as apartment entries with an interphone panel. Refer to
Diagrams 2b & 2c. In each case the interphone input (WET 1)
will activate the strike relay only. If a courtesy switch is located in
the vestibule, it is connected to DRY 2 (Terminals 15 & 16).
This input is only active when the strike relay is energized.
Another application using this mode is door sequencing in
one direction only. Connect Door 1 operator to relay 1, and
door 2 operator to relay 2. The delay between the two doors
is adjusted via the DOO RL2 potentiometer. For bi-directional
sequencing refer to specific set-up instructions below.

Access Control Mode

Set dip switches as shown. Also refer to Diagram 2a.
Typically the access panel (or time clock) will be wet (powered)
therefore connect to WET 1 (Terminals 9 & 10).
The exterior activating switch is wired to DRY 2 (Terminals 15 &
16). This input signals the door operator (Relay 2), and is only
active when the strike relay is energized.

An interior switch may be connected to DRY 1 (Terminals 11
& 12). This input will always unlock and open the door when
activated. (Regardless of the status of input connected to WET
1). If the interior switch is Wet (powered) connect to WET 2
(Terminals 13 & 14).

Smoke Evac. Mode

(Mode 3)
Set dip switches as shown. Also refer to Diagram 3.
Suitable for connection to a Fire Alarm Panel, this mode will fire
the electric lock momentarily, then hold in the operator relay
until the input is released.
Connect the Wet (powered) output of the Fire panel to WET
2 (Terminals 13 & 14) A device with a dry output such as a
Presence sensor will connect to DRY 1 (Terminals 13 & 14).
Latching/Rachet Mode
Set dip switches as shown.
Also refer to Diagram 4a & 4b.
Latching – Upon receipt of a signal (or contact closure)
on WET1 or DRY1, RELAY1 will activate for an adjustable
time. Then after an adjustable time, RELAY2 will activate.
RELAY2 will stay held until a second contact closure contact
closure on DRY/WET1.
Ratchet - Upon receipt of a signal (or contact closure) on WET2
or DRY2, RELAY1 will activate and stay latched. Then after an
adjustable time, RELAY2 will activate and stay latched. A second
activation of WET/DRY2 will release both relays.
Bi-Directional Sequencing Mode
Mode 5: Momentary
Mode 6: Maintained
Set dip switches as shown. Also refer to Diagram 4.
Turn on power and activate the Interior input (switch). Observe
LED1, which should light immediately. The length of hold time is
determined by adjusting the pot marked DOR/RL1, clockwise for
more time, counter clockwise for less time. The delay between
the two doors is adjusted via the DOO RL2 potentiometer. After
the above-mentioned delay, LED2 should light. The length of
hold time is adjusted by the pot marked DOR/RL2.
The ideal time delay between the two doors is best set by actual
walk-testing. It should be set so that a person can walk in either
direction without having to pause before the second door
activates. Test in both directions.
If an emergency (or anti-entrapment) switch is desired in the
vestibule, then wire that switch directly to one of the operator
inputs. Usually the exterior door is used in this case. Once the
desired operation is achieved, proceed to Section 4, for
System Inspection Instructions.
