CAMDEN CX-33 Installation Instructions Manual page 6

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 19) for the following
connections.
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
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 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 specifically
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 20) for the following
connections:

CX-33 Advanced Logic Relay Installation Instructions
to the General
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.
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 3M_______________
Mag Lock with N.C. Fire Alarm (Mode 12)
This mode is identical to Mode 11 (Section 3L)
except the Fire Alarm input is a N.C. circuit (rather
than N.O.). See previous section for wiring and
adjustments, & refer to Diagram 12, (Page 21).
Section 3N_______________
Special purpose sequencer (Mode 13)
In this unique mode, Input 1 sequences Relays 1 & 2,
and Input 2 sequences Relays 2 & 3.
Refer to Diagram 13 (Page 22) for connections.
Once input and output connections are made,
program the unit according
Programming Instructions on page 1, and walk-test
the installation. Perform any timing adjustments.
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, for System Inspection Instructions.
