Connections For The 12 Terminal Input Connections

NOTE:

The push-button and slide switch control terminals are designed to activate components with a load 

rating no higher than 10 amps each. Terminal outputs 3, 4 & 5 can be ganged (grouped) to handle a 30 
amp component.

Connecting Components For Slide-Switch Control...

1.

Route and connect the desired component wire to Terminal #1.

2.

Route and connect the desired component wire to Terminal #2.

3.

Route and connect the desired component wire(s) to Terminal’s #3, 4 & 5 (30 amps).

NOTE:

Terminals #3, 4 & 5 can have a component connected to each of these terminals. It is 

important to understand that these three terminals can not be turned on individually! 
However a high-amperage component (no greater than 30 amps) can be controlled by the 295HFS6 if 
these three terminals are spliced together and connected to the component.

Configuring The Slide-Switch Control Functions...

In the default configuration (as shipped from the factory), the slide switch is configured as follows:

Slide Position #0

 . . . . .No Terminal active

Slide Position #1

 . . . . .Terminal #1= ACTIVE, Terminal #2= inactive, Terminals #3, 4 & 5= inactive

Slide Position #2

 . . . . .Terminal #1= inactive, Terminal #2= ACTIVE, Terminals #3, 4 & 5= inactive

Slide Position #3

 . . . . .Terminal #1= inactive, Terminal #2= inactive, Terminals #3, 4 & 5= ACTIVE

The slide switch configuration can be 

altered so that any combination of these 
terminals may be active or inactive in any of 
the three functioning slide positions. The 
slide switch configurations are controlled by 
two Dip Switch banks which are located on 
the top circuit board of the 295HFS6.
Before proceeding, disconnect all the input 
harness connectors from the rear of the 
295HFS6. Access to the Dip Switch banks is 
gained by removing four small phillips-head
screws located at the four corners of the 295HFS6 face plate. With these screws removed, slide the 
chassis housing cover towards the rear of the 295HFS6. It is not necessary to slide this cover more than a 
few inches, as the Dip Switch banks are located just behind the control panel. 

The Dip Switch Chart illustrates how the dip switches are configured. As shown, the configuration for 

slide switch position #1 is controlled by dip switch #’s 2, 3 & 4 on bank 1. Dip switch #2 (which controls 
Terminal #1) is in the ON position, while #3 (Terminal #2) & #4 (Terminals #3, 4 & 5) are in the off position. 
This means that when the slide switch is moved to position #1, Terminal #1 alone becomes active. 

Slide switch position #2 is controlled by dip switch #5 on bank 1, and by dip switch #1 and #2 on bank 

2. In the default configuration, dip switch #5 (Terminal #1) is off, dip switch #1 (Terminal #2) is ON and dip 
switch #2 (Terminals #3, 4 & 5) is off. This means that when the slide switch is moved to position #2, 
Terminal #2 alone is active, while Terminal #1 and Terminals 3, 4 & 5 are inactive.

Slide switch position #3 is controlled by dip switch ‘s 3, 4 & 5 on bank 2. In the default configuration, 

dip switch #3 (Terminal #1) is off, dip switch #4 (Terminal #2) is off and dip switch #5 (Terminals #3, 4 & 5) 
is ON. This means that when the slide switch is moved to position #3, Terminals #3, 4 & 5 are active, while 
Terminals #1 & #2 are inactive.

Enabling Siren Tones through Slide Switch Position #3...

Slide switch position #3 is configured to automatically activate siren tones (in it’s default configuration). 

If this is not desired, make sure that dip switch #1 on bank 1 is in the off position. Please note that siren
