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
