STEP 4: SET THE TRANSMITTER BUTTON RESPONSE(S) 

There are three DIP switches used to set the 
transmitter button response(s). See Figure 4 
or Figure 5. 
 
To disallow receiver response to transmitter 
buttons, move the DIP switch(es) to the LEFT.  
All button switches are factory set to ON. 

 

Switch S1, 1 controls Button #1 and 
Button #4

*

 

 

Switch S1, 2 controls Button #2 

 

Switch S1, 3 controls Button #3

 

* If using a CPT4 transmitter, Button #4 reacts 

to Button #1 settings, but uses a unique 
identification number and facility code.

SETTING A FIXED FACILITY CODE (FFC) 

The FFC switch must be in the ON 
position (switch set to right). 

Set the receiver’s facility code switches 
(labeled 0-5) to match the facility code of 
the access control system. 

Refer to the switch settings chart in the 
Appendix on page 6 for assistance.

 

 

NOTE: 

For installations that require the 

facility code of the transmitters to be 
passed to the access control system, 
set the FFC switch to the OFF position 
(set switch to left).

  Facility codes are 

set in the transmitter at the factory to 
avoid code duplication.
