CX-12 Switching Network

& Bi-Directional Door Sequencer

Installation Instructions

Page 1 of 10

Section 1__________________

General Description

The CX-12 is the latest generation multi-purpose

timer. It is designed to be versatile yet user friendly

with easy to understand terminology and

adjustments. (It supersedes Model CX-11 Ultra)

Used as a make/break relay (or Switching Network) it

eliminates the binding of locked automatic doors, by

delaying the door operator until the strike or

electromagnet (de) activates first.

A new feature of this model is the ability to select one

of 4 Modes of operation – momentary; maintained

with Relay 1 held; maintained with Relay 2 held; and

bi-directional door sequencing (SEE DIAGRAM 04).

In the Momentary position, even a stuck switch input

will allow the door to time out and close, thereby

providing security to occupants. The CX-12 will

however, still operate normally if one of the other

inputs is activated. Essentially, it ignores the faulty

activation source, as all inputs are isolated.

The inputs to the CX-12 may be either dry or wet

(powered), meaning that 3-terminal radio receivers

may be connected directly to the CX-12 without fear

of malfunction. SEE DIAGRAM 01.

Additionally, we provide a direct connection from an

apartment interphone panel. Only Relay #1 (strike)

will operate when a voltage is applied to this input. A

vestibule courtesy switch will be energized for the

time set by Pot. 1. SEE DIAGRAM 03 a or b.

Select Relay 1 Maintained for an Access Control

application. When a maintained signal is applied to

WET 1 input, the lock will remain energized, while the

DRY 2 input allows a wall switch to open the door. An

input on DRY 1 will always unlock and open the door.

SEE DIAGRAM 02b.

Select Relay 2 Maintained if you are connecting the

CX-12 to a fire alarm panel, or to a presence sensor.

In this mode the lock will fire momentarily but the

operator relay will be held in as long as the input is

maintained. SEE DIAGRAM 02a.

For latching (ratchet or alternate action) functions, we

recommend our Model CX-1000/78 multi-purpose

timer, or Model SA-1 Switching Network.

IMPORTANT: Do not apply power to the unit until

you have read the instructions fully and made the

required adjustments.

Installation

Mounting

The LED’s are visible through the wrap-around

sleeve, which also has cutouts for adjusting the

potentiometers, and setting the dip-switch. Once the

unit has been adjusted, it may be tucked up into the

operator header or affixed using the supplied Velcro.

Wiring

Wiring of this unit is dependent on the mode desired,

however the following commonalities apply.

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.

CAUTION: 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.

APPLICATIONS

& SET-UP INSTRUCTIONS:

STANDARD TIMER MODE

Set dipswitches as shown >

Refer also to Diagram 01.

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 to send just a momentary pulse (1 or 2

seconds only).

Observe the door and adjust timers until desired

operation is observed.

The above dipswitch setting is also used for

applications such as apartment entries with an

interphone panel. Refer to Diagrams 03a & 03b.

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.

EXTENDED TRIGGER MODE – RELAY 1

Set dipswitches as shown >

Refer also to Diagram 02b.

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).

EXTENDED TRIGGER MODE – RELAY 2

Set dipswitches as shown >

Refer to Diagram 02a.

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).

Bi-Directional Sequencing MODE

Set dipswitches as shown >

Refer to Diagram 04.

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.

Section 4 _________________

System Inspection Instructions

After the Installation and operational check of the

system:

1. Place warning label on the door (as per ANSI

A156.10 or A156.19 guidelines). This will

advise the person entering the swing side

zone that the door will move.

2. Instruct the owner on door system operation

and how to test it. This should be checked

on a daily basis.

3. Instruct the owner on what to do if the door or

any of its components become damaged.

4. Strongly recommend to the owner that the

complete entry be inspected twice a year as

part of the service agreement.
