Double Interlock Preaction, Single Zone Detection
Potter Program #9

1.  Apply power to the panel. 
2.  Slide program switch down. 
3.  Press the FUNCTION button until display reads “PASS-

WORD=000.”

4.  To enter a password, press the SELECT button until the prop-

er number is displayed above the “^” symbol; then press the 
SET button to move to the next digit. After entering the third 
number, the display will change. (All panels are shipped with a 
“000” password). 

5.  Press the FUNCTION button until the display reads “PRO-

GRAM ##.” (the second “#” character refers to the current 
program number between “0” and “24”). 

6.  Press the SELECT button until the display reads “PROGRAM 

#9.” 

7.  Press the SET button. 
8.  The panel is completely programmed except for the custom 

banner and zone messages.  Slide the program switch back 
up.

INPUTS:              1 supervisory zone, 1 conventional detection zone, 1 low air supervisory zone, 1 waterflow zone, 1 low air 

alarm zone.

OUTPUTS:  

1 general alarm, 1 supervisory, 1 waterflow, 1 solenoid release circuit.

OPERATION:    Activation of the conventional detection zone and the low air alarm zone at the same time (or operation of 

the manual pull station within the PrePak cabinet) will operate the solenoid release circuit and the general 
alarm bell.

 

Activation of the conventional zone only will operate the general alarm output.

 

Activation of the low air supervisory zone will operate the supervisory bell output.

 

Activation of the waterflow zone will operate the waterflow bell output.

               

Activation of the low air alarm  zone will operate the supervisory bell output. It will not operate the alarm 
relay.

 

When Zone #1 is in alarm, Output #1 will operate.

 

When Zone #2 is activated, Output #3 will operate.

 

When Zone #3 is in alarm, Output #2 will operate.

 

When Zone #4 is activated, Output #3 will operate. This will create a supervisory condition not an alarm 
condition. The alarm relay will not operate, the supervisory relay will.

 

When both Zones #1 and #4 are activated at the same time, the solenoid circuit will operate.

Note:

(1) 

The Butterfly valve in the PrePaK assembly is connected to Supervisory 2 input of the Potter PFC-4410RC Releasing/

Control panel

(2)

 

The emergency manual release within the PrePak cabinet is wired into the conventional detection zones 1 and 2, and is 

designed to release the solenoid for setup and testing purposes.

For additional Information, please refer to the “Installation, Operation, and Instruction Manual” for the Potter 
PFC4410-RC Releasing Control Panel (provided with the unit).
