CAMDEN CX-33 Installation Instructions Manual page 3

Section 3C_______________
2 Door Latching Airlock (Mode 3)
Utilizing door position switches, (Camden CX-MDC,
or equivalent) this mode ensures that only one door
in an airlock will be open at a time.
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 11) 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
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, Pg 7 for System Inspection Instructions.
Section 3D____________________
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 12). A
more complex sequencer utilizing 4 switch inputs,
and allowing for one door with an electric lock is
shown in Diagram 4b (Page 13).

CX-33 Advanced Logic Relay Installation Instructions
Providing the
to the General
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
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, Pg 7 for System Inspection Instructions.
Section 3E____________________
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 14) for the following
connections.
The CX-33 allows for dry and/or powered momentary
connections to the Interphone panel (DRY 1 and
WET inputs respectively).
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).
Output #1 is for the electric lock, and Output #2 is for
the door operator. (Optional - Output #3 is controlled
solely by DRY 4 Input).
