CAMDEN CX-33 Installation Instructions Manual page 5

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 17) for the following
connections.
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.
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
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 3J_______________
Lock-out Relay Plus (Mode 9)
This mode combines, for the first 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.

CX-33 Advanced Logic Relay Installation Instructions

to the General
Refer to Diagram 9, (Page 18) 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.
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
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

Low Energy SAM Plus (Mode 10)
This mode combines a Low-Energy Secondary
Activation Module (SAM) with a switching network
(aka make/break relay).
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.
