INSTA L L AT I O N I NST RU CTI ONS
Section 3 C
2 Door Latching Airlock (Mode 3)
Utilizing door position switches, (CX-MDC, or equivalent) this
mode ensures that only one door in an airlock will be open
at a time. Providing the opposite door is closed, one switch
activation will latch open (unlock) the door, and the second
activation on the same input will allow the door to close (lock).
3 outputs allow for one of the doors to have an electric lock
and a door operator. (Alternatively, the doors could have
locks only and no operators.)
The CX-33 is unique in the industry because it also provides
the ability to add an adjustable "Walk-away" time. If the door
input has been activated but the door has not been opened,
the relay will reset (re-lock). Both doors have their own
respective adjustable timers. (If the time is set to zero, then
this feature is disabled). Refer to Diagram 3, (Page 13) for the
following connections.
Wire the activating device(s) for Door #1 to DRY 1 terminals.
Wire the activating device(s) for Door #2 to DRY 2 terminals.
Wire the respective door contact switches to Inputs 3 & 4.
(The contact circuit must be closed when the door is closed).
Wire the outputs as shown. If a lock is not used, set H1 & D1
timers to zero (0.0), and Relay 1 will be ignored.
Once input and output connections are made, program the
unit according to the General Programming Instructions on
page 1, and walk-test the installation. Timing adjustments
may need to be made.
It is NOT recommended to add the "Delay-on-activate" (or
nuisance delay) feature in this mode!
Once the desired operation is achieved, proceed to Section 4,
(Page 9) for System Inspection Instructions.
Section 3 D
Bi-Directional Door Sequencer (Mode 4)
This mode sequences all 3 relays in both directions, also
known as bi-directional door sequencing.
A basic 2-door sequencer with just two inputs and two
outputs is shown in Diagram 4a (Page 14). A more complex
sequencer utilizing 4 switch inputs, and allowing for one door
with an electric lock is shown in Diagram 4b (Page 15).
DRY 1 or WET 1 inputs sequence Relay 1 to Relay 2 to Relay 3.
DRY 2 input sequences Relay 3 to Relay 1 to Relay 2.
Input 3 only sequences Relay 1 to Relay 2, and Input 4 only
activates Relay 3.
If a relay (Relay 1 for example) operation is not desired it
can be turned off by setting the time delays to zero (in this
example H1 & D1).
Once input and output connections are made, program the
unit according to the General Programming Instructions on
page 1, and walk-test the installation. Timing adjustments
may need to be made.

In addition, you can add a "Delay-on-activate" (or nuisance
delay) to this mode by setting time via Step 8 of the Program
Mode. If this feature is used, any input will have to be held for
at least the time indicated on the display before the CX-33 will
activate. If this feature is not wanted, set the time to zero (0.0)
Once the desired operation is achieved, proceed to Section 4,
(Page 9) for System Inspection Instructions.
Section 3 E
Apartment/Condo Application (Mode 5)
This application is for a switching network (or make/break
relay) that controls an apartment or condo front door. When
a visitor arrives and calls a tenant on the phone entry system,
the tenant can "buzz down" and unlock the door for the visitor.
During this operation, a courtesy switch is put into the circuit
enabling the user to press the switch and open the door.
Once the lock releases, the courtesy switch is removed from
the circuit. The inside switch will always unlock and open
the door.
Refer to Diagram 5, (Page 16) for the following connections.
CX-33 allows for dry and/or powered momentary connections
to the Interphone panel (DRY 1 and WET inputs respectively).
Wire the "Courtesy Switch" to DRY 2 input. Wire the inside
switch to DRY 3 input. An optional Key switch can be added
for use by tenants - wire to either DRY 1 (to unlock only), or
DRY 3 (to unlock and open door). An optional Fire Panel Input
can be connected to DRY 4. Output #1 is for the electric lock,
and Output #2 is for the door operator.
Once input and output connections are made, program the
unit according to the General Programming Instructions on
page 1, and walk-test the installation. Timing adjustments
may need to be made.
In addition, you can add a "Delay-on-activate" (or nuisance
delay) to this mode by setting time via Step 8 of the Program
Mode. If this feature is used, any input will have to be held for
at least the time indicated on the display before the CX-33 will
activate. If this feature is not wanted, set the time to zero (0.0)
Once the desired operation is achieved, proceed to Section 4,
Page 9 for System Inspection Instructions.
Section 3 F
Access Control Application (Mode 6)
This application is for a control relay that takes a maintained
signal and unlocks a door for an extended time. During this
time, an exterior momentary switch is put into the circuit
to allow the door to activate automatically. After the access
system or time-clock has released the signal, the door relocks,
and the exterior switch is removed from the circuit.
At any time, the inside switch will unlock and open the door.
Refer to Diagram 6, (Page 17) for the following connections.
The CX-33 allows for dry and/or powered maintained
connections to the Access System / time clock (DRY 1 and/ or
WET inputs respectively). Wire the Exterior momentary Switch"
to DRY 2 input.
