OPTION SWITCHES
An internal 8-position DIP switch on the circuit
board may be changed to select various op-
tions. The cover for the unit must be removed
to access the DIP switch.
Accessing Option Switches
- The cover is
held in place by a snap-fastener on the back of
the unit. While holding the cover on the sides
press hard with your fingers on the back of the
unit. The chassis will slide out the front.
Adjusting Option Switches
- the DIP Switch is located on
the internal PCB assembly board toward the right side of
the unit. Switch 1 is toward the back of the unit. Switch
‘ON’ position is toward the inside side of the unit.
SW-1 Not Used… Leave Off.
SW-2 Not Used… Leave Off.
SW-3 Horn Disable
- Turn this switch ON to disable Horn tone.
SW-4 Not Used… Leave Off.
SW-5 Not Used… Leave Off.
NOTE:
Earlier models with S/N lower than 04190000 have a 5 position DIP switch and only offer
the traditional auxiliary input.
Traditional Auxiliary Input
- On earlier models of the SA-400, the auxiliary input is activated with
positive (+VDC)
AND
negative (-VDC). A normally open horn ring circuit or switch is required for
proper operation. Possibly use this setting if the auxiliary input is wired for an earlier SA-400.
