CX-12 PLUS DOOR INTERFACE RELAY
INSTALLATION INSTRUCTIONS
Momentary Operation
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 PLUS 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 PLUS may be either dry or wet (powered),
meaning that 3-terminal radio receivers may be connected directly
to the CX-12 PLUS without fear of malfunction. See Diagram 1.
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 2b or 2c.
Maintained Operation
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 2a.
Select Relay 2 Maintained if you are connecting the CX-12 PLUS
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 3.
Latching/Ratchet Operation
In this mode the CX-12 PLUS will latch Relay2 with a momentary
activation on Dry/Wet1. Relay2 is released when Dry/Wet1 are
activated a second time. If Dry/Wet2 are activated, Relay1 and
Relay2 are latched until Dry/Wet2 are activated again.
Washroom Door Controller
In this mode, complete control of a single occupant barrier-free
washroom is obtained. It allows the user lock and secure the
door from the inside by depressing a Push-to-Lock button. The
exterior wall switch is removed electronically from the circuit.
To exit the washroom, simply exit manually via the lever-handle
set (the Door Contact Switch resets the relay), or, press the
interior wall switch to unlock and activate the door operator.
The door remains unlocked upon closure.
Another feature is the ability to use the CX-12 PLUS on
“Normally Secure” washrooms. In this mode, the door is usually
locked. To gain access, the user must first swipe a card, or enter
a code into the Access System (ie. Keypad), which then signals
the CX-12 PLUS to unlock and open the door. Once inside, the
occupant presses the Push-to-Lock button, which removes the
exterior wall switch from the circuit.
Exiting may be accomplished manually via the lever-handle set
(the Door Contact Switch resets the relay), or, by pressing the
interior switch to unlock and activate the door operator.
The door will re-lock upon closure.
Note: We highly recommend the use of a regulated power
supply when powering strikes for barrier-free washroom
applications where the strike power may be maintained
from a few minutes to many hours.
We offer a low-cost board-only regulated power supply
- CX-PS13 V3, which can be powered from a small 24VAC
transformer, (or the auxiliary power on the door control)
and will supply clean, filtered & regulated 24VDC power for
the strike.
Bi-Directional Door Sequencer
In this mode, the relay will sequence two Automatic doors, in
both directions. Upon a switch closure from one side, a signal is
sent to the first door (relay 1), then after an adjustable delay, the
second door (relay 2) receives a signal. When a switch closure is
made from the opposite side, the sequence is reversed – Relay
2 is activated, then after the adjustable delay, relay 1 activates.
When used as a door sequencer the user can select either
momentary position for the inputs, or maintained position.
In the momentary position, even a stuck switch input will allow
the door to time out and close, thereby providing security to
the occupants.
The CX-12 PLUS will however, still operated normally if one
of the other inputs is activated. Essentially, it ignores the
faulty activation source, as all the inputs are isolated. In the
maintained position, a switch that is held on will cause its
respective relay (operator) to be held on. So switch #1 would
hold in relay #1, and switch #2 would hold in relay #2.
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.
IMPORTANT: Do not apply power until you have read the
instructions fully and made the required adjustments.
4. 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.
