CX-33 Advanced Logic Relay
Installation Instructions
Firmware Ver. 3.2
Section 1
General Description
The CX-33 is the latest generation multi-purpose logic control.
It is designed to be versatile yet user friendly with easy to
understand terminology and adjustments. The 15 different
operating modes ensure it will be useful in nearly every
automatic door or security application.
A total of 5 inputs (4 dry, and one wet or powered) allow for
more exibility in wiring to different types of activating devices.
The wet or powered input is useful when connecting to
3-terminal radio receivers, telephone entry systems panels, or
for connecting to motors when used as a Lock-out Relay.
The 3 buttons for mode selection, including separate UP and
DOWN buttons, offer fast and easy programming. The large
3-segment display is the easiest to view and understand in
the industry.
A total of 3 heavy-duty 3 amp relays allow for varied
sequencing applications. For example, in restroom use, the
third relay is ideal for “Occupied” or “In Use” signage.
(Note: ouputs are dry, not powered.)
Section 2
Installation
IMPORTANT: Do not apply power to the unit until you
have read the instructions fully and made the required
adjustments.
Mounting
The CX-33 should be mounted in a clean dry location out
of direct contact with the elements. Suitable locations
include inside a metal enclosure, operator header, or above
a false ceiling.
The Display & LED’s are visible through the clear plastic
case, which also has cutouts for the programming buttons
and terminal strips. Once the unit has been wired and
adjusted, it may be tucked up into the operator header or
afxed using the supplied Velcro or 2 sheet metal screws.
Wiring
Wiring of this unit is dependent on the mode desired,
however the following commonalities apply:
The unit will operate on 12 or 24 volts, AC or DC. Connect to
Terminals 1 & 2, which are non-polarity sensitive.
NOTE: We highly recommend the use of a regulated power
supply when powering equipment in certain modes such as
the barrier-free washroom application 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,
which will supply clean, ltered & regulated 12 or 24VDC
power for the strike and CX-33.

CX-33 Advanced Logic Relay Installation Instructions
Programmable Inputs
The Dry and Wet Inputs are programmable to accept either a
Normally Open contact or a Normally Closed contact. Table 1
shows the default settings for all modes.
Changes made to the inputs are saved and will remain even
through a power cycle. Once the Mode is selected, changes
to the inputs can be programmed. If the Mode is changed,
the inputs are set to their default values for that mode.
If the Mode is set back to the previous mode, all input
programming changes are lost, and the default values
are restored.
For example, the mode is set to Mode 7. Dry 4 is reprogrammed
to accept a NO contact. The mode is changed to Mode 8 and
then changed back to Mode 7. Dry 4 is now defaulted to
accept a NC contact.
Wet Input
The Wet Input activates at 4.5V AC/DC and will deactivate at
2.8V AC/DC. Some older telephone entry panels outputting
wet signals, do not typically reduce their output to 0V when
inactive. There is typically a stray voltage that can exceed
3v which does not deactivate the Wet Input. In these cases,
please use the provided 50Ω, 1Watt resistor in series with
the Wet Input.

3 Relay Switching network
(Mode 1)
This mode sequences all 3 relays (in one direction), using
what we call “mixed mode triggering”. Some popular
applications include basic strike and operator installations,
smoke evacuation, stairwell doors, or latching applications.
Refer to Diagram 1, (Page 11) for the following connections.

For momentary devices, wire to either DRY 1 or WET 1 input
terminals. Wire a maintained device to DRY 3 input if you
wish to hold relay 1 (a lock for example). Wire a maintained device
to DRY 2 input if you wish to hold relays 2 & 3 (ie -door operators).
Input number 4 is for latching applications. Each momentary
switch closure will toggle relays 2 & 3.
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.
If Hold time is = 0, the relay doesn’t turn on. If Delay time = 0,
then the relay comes on immediately. For example, if you wish
Relay 2 & 3 to both come on at the same time, set D2 time to
zero (0.0).
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.

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.
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

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.
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.
Page 4 of 28
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.

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 16) 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). 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

to zero (0.0)
Once the desired operation is achieved, proceed to Section 4,
Pg 9 for System Inspection Instructions.
Section 3F
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. Wire the inside momentary 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). DRY 4 Input is used if you wish to
connect a Fire Alarm Panel.
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

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.
Section 3G
Normally Unlocked Restroom
(Mode 7)
In this mode, control of a single occupant barrier-free
washroom is obtained. It allows the user to lock and secure
the door from the inside by depressing a Push-to-Lock button
(once door is in the closed position). The exterior wall switch
is removed electronically from the circuit.
To exit the washroom, simply exit manually via the store-room
function lever-handle set (the Door Contact Switch resets the
relay), or, press the interior wall switch to unlock and signal
the door operator. The door remains unlocked upon closure
(see Mode 8 for normally locked doors). The CX-33 also
provides a relay dedicated for “Occupied” & “Door Locked”
signage.
Refer to Diagram 7, (Page 18) for the following connections.
The outside wall switch, inside wall switch, and Push-to-Lock
switch are all N.O. momentary switches. Connect as shown.
The Door Contact Switch circuit must be closed when the
door is closed and open when the door opens.
A fail-safe electric strike is recommended and connects
to Relay 1 (although a fail-secure strike can also be used).
The automatic door operator connects to Relay 2, and the
signage connects to Relay 3. (As a reminder, no power is

Normally Locked Restroom
(Mode 8)
In this mode, control of a normally locked single occupant
barrier-free washroom is obtained. It allows the user to secure
the door from the inside by depressing a Push-to-Lock button.
The exterior means of ingress is removed electronically from
the circuit.
To exit the washroom, simply exit manually via the store-room
function lever-handle set (the Door Contact Switch resets the
relay), or, press the interior wall switch to unlock and signal
the door operator. Exiting the washroom resets the relay, and
the door is re-locked upon closure.
The CX-33 also provides a relay dedicated for “Occupied &
“Door Locked” signage (recommended).
Refer to Diagram 8, (Page 19) for the following connections.
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 3J
Lock-out Relay Plus
(Mode 9)
This mode combines, for the rst time, a lintel mount safety
sensor lock-out relay (LOR) with a switching network (aka
make/break relay). The voltage sensing circuit can be utilized
with motors/controls up to 120 volts AC/DC. The adjustable
hold timer (lock-out) is then matched to the door closing
time. “Cancellation” inputs are provided for connection to
rail-mounted door beams.
In addition, three inputs and two relays are provided for the
switching network function.
Refer to Diagram 9, (Page 20) for the following connections.
LOR Circuit:
A parallel connection is made to the two motor wires running
from the Operator (motor) to its control. If the motor is AC,
then polarity is not an issue. The CX-33 is triggered by the
AC voltage going from high to low.
If the motor is DC, then the wires are polarity sensitive. If
Relay 3 LED doesn’t illuminate when the door is closing, then
just reverse the two terminal connections at the CX-33.
The outside means of ingress – Keypad, Key switch, or
Prox-reader, plus the inside wall switch, and Push-to-Lock
switch are all N.O. momentary devices. Connect as shown.
The Door Contact circuit must be closed when the door is
closed and open when the door opens.
A fail-secure electric strike is typically used, although a
fail-safe strike can also be used. Connect to Relay 1. The
automatic door operator connects to Relay 2, and the signage
connects to Relay 3. (As a reminder, no power is provided on
the relay outputs – they are dry contacts).
As a safety feature, the door cannot be “secured” via the
“Push-to-Lock” button until the door is completely closed (to
prevent kids from pressing the lock button and running away).
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.
Page 6 of 28
Input 1 is for the N.O. relay contacts of the photo beam.
The beams are typically mounted at the end of guide rails
and designed to reset the LOR in the event anyone should
walk into the swing path when the door is in the closing cycle.
Relay 3 output is to be connected in SERIES with the safety
device and the Safety Circuit of the operator.
Optional Switching Network:
Wire the activating device(s) to DRY 1, DRY 2 or DRY 3
terminals. Wire the outputs as shown to Relays 1 & 2.
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”

CX-33 Advanced Logic Relay Installation Instructions
Section 3K
Low Energy SAM Plus
(Mode 10)
This mode combines a Low-Energy Secondary Activation
Module (SAM) with a switching network (aka make/break
relay). Utilizing a door position switch input, this mode
enables or disables a door mounted presence sensor. The
sensor is put into the circuit when a wall switch is pressed
(a Knowing Act). This allows an object or person in the path
of the door to be detected. The door will not close until the
object or person leaves the door swing path. The sensor
remains in the circuit until the door is closed.
When the door is opened manually, the safety sensor is not
in the circuit and the door operator functions as a manual
door closer.
A unique feature of the CX-33 is the automatic reset feature.
If a switch has been pressed, but the door has not opened
within 60 seconds (because it is locked, for instance), the unit
will reset. This will save wear and tear on the lock and operator.
In addition, one input and two relays are provided for the
switching network function.
Refer to Diagram 10, (Page 21) for the following connections.
Section 3L
Mag Lock with N.O. Fire Alarm
(Mode 11)
Commonly seen in hospital corridors, this version of a
switching network (make/break relay) is specically designed
for doors with mag locks.
A wall switch signals the relay, which unlocks, and opens the
door for an adjustable time. Utilizing the door position switch,
the CX-33 will not re-apply power to the magnetic lock until
the door is fully closed. The relay also provides for a normally
open Fire Alarm input, which when activated, unlocks the
door and disables the wall switch inputs.
Refer to Diagram 11, (Page 22) for the following
connections:
Momentary switches connect to DRY 1 and/or WET terminals.
Maintained devices connect to DRY 2 input (optional). The N.O.
Fire Alarm signal is wired to DRY 3 input, and the Door Position
Switch connects to DRY 4 input. The circuit must be closed
when the door is closed, and open when the door opens.
The magnetic lock connects to the Common and N.C terminals
of Relay 1. The door operator connects to the Common and
N.O. terminals of Relay 2. Relay 3 output is optional.
SAM Circuit:
Connect the momentary activating switch(es) to DRY 3 input.
The door mounted sensor connects to DRY 2 input, and the
magnetic contact switch connects to DRY 4 input. The contact
switch circuit must be closed when the door is closed, and
open when the door opens.
Relay 3 output is to be connected to the Activate circuit of the
door operator.
Optional Switching Network:
Wire the activating device(s) to DRY 1 terminals. Wire the
outputs as shown to Relays 1 & 2.
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.

Delayed Relay Activation (Mode 14)
Refer to Diagram 14 (Page 25) for connections. In this unique
mode, a Switch connected to Input 1 will cause Relay 1 to re
immediately, but not allow Relays 2 & 3 to re until a pre-set
elapsed time has expired. The user must push and hold the
switch for this length of time. A Fire alarm input is provided –
DRY 2 or WET 1. A Bypass or Shunt Keyswitch is connected to
DRY 3, and a N/C door position switch is connected to DRY 4.
Output 1 is for a local siren, Output 2 is for the electric lock,
and Output 3 is for status monitoring.
Once connections are made, power up and adjust H1 time for

used. Input 2 allows for an optional secure entry keypad (or
similar), or connection to a re alarm.
Once connections are made, power up and program the unit
according to the General Programming Instructions on page
1, and walk-test the installation. Adjust H1 time for the lock
time, D1 for the time between the lock and operator , and H2
for the time delay for the auto door operator. D2 and H3 are
not used in this mode.
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 3R
Bi-Directional Door Sequencer with
Access Control Input (Mode 15)
This mode sequences all 3 relays in both directions, also
known as bi-directional door sequencing. Refer to Diagrams
15a & 15b on pages 27 and 28.
Access control systems can be connected to the WET input to
unlock the door before sequencing the operators. The door
remains unlocked while there is a maintained signal on the
WET input.
DRY1 input is only active while there is signal on the WET input.
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.
Note: Not for use as UL compliant delayed egress.
Section 3Q
Lock Down Mode (Mode 7)
In this mode, during normal operation the all-active switches
(both connected to Input 1) trigger the auto door operator.
When desired, a “Lock-Down” switch located remotely (in
a school ofce for instance) will activate the door lock, and
disable the door switch input. A separate output can drive a
status LED / light. When the “Reset” button (connected to
Input 4) is momentarily depressed the door unlocks, and the
system resets.
Refer to Diagram 7a (page 26) for connections. The all-
active switches and Lock-down Switch are all normally open
Page 8 of 28
DRY 1 input sequences Relay 1 to Relay 2 to Relay 3. DRY 2
input sequences Relay 3 to Relay 1 to Relay 2. DRY 2 input
will always unlock the door before sequencing
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.
CX-33 Advanced Logic Relay Installation Instructions
Section 4
System Inspection Instructions
After the Installation and operational check of the system:
1. Place any applicable labels on the door (as per ANSI
A156.10 or A156.19 guidelines).
2. Instruct the owner on door system operation and how to
walk-test it. This should be checked on a daily basis.
3. Instruct the owner on what to do if the door or any of
its components become damaged.
4. Strongly recommend to the owner that the complete
entry be inspected twice a year as part of the service
agreement, or at least once per year as per AAADM
guidelines.
