CAMDEN CX-33, Installation Instructions Manual

Page 8 of 28

1 - 2 - 3, and Input 4 sequences Relays 1 - 3 - 2.

Refer to 

Diagram 13 

(Page 24) for connections. Once input 

and output connections are made, program the unit according 
to the General 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, 
Pg 9 for 

System Inspection Instructions

.

Section 3P

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 fire 

immediately, but not allow Relays 2 & 3 to fire 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 

the length of time switch 1 must be pressed. H2 time is the 

minimum ON time for Relay 2 (lock).

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 office 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 

switches. The RESET switch is normally closed. Connect 
as shown. A fail-safe electric strike, or mag lock should be 
used. Input 2 allows for an optional secure entry keypad (or 
similar), or connection to a fire 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. 

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
