Door Timed Airlock; 2 Door Latching Airlock; Bi-Directional Door Sequencer - CAMDEN CX-33 Installation Instructions Manual

Section 3B

2 Door Timed Airlock

(Mode 2)
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. Each output hold time is
adjustable from 1 – 50 seconds. 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.)
Refer to Diagram 2, (Page 12) 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, Pg 9 for System Inspection Instructions.
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. 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.

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 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,
Pg 9 for System Inspection Instructions.
