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 Two-Tone - Turn this switch on to replace Phaser with Two-Tone.
.
SW-2 Mechanical Override - Pressing the Siren push-button normally produces Horn tone while
the rotary selector switch is in Mechanical. Turn this switch on to manually override Mechanical
tone instead.
SW-5 Not Used… Leave Off.
HORN RING CYCLER 2 (HRC2) - Turn on DIP SW-3 and SW-4 to enable this feature. Also
connect the auxiliary input to the horn ring or other switch. While the siren is in standby, tap the
horn ring to bring the unit out of standby into Mechanical tone. Repeatedly tapping the horn ring
will cycle through Mechanical, Wail, Yelp, and Phaser tones. Tapping the horn ring twice quickly
will stop the siren tones and return the unit to standby. Pressing and holding the horn ring will
produce Horn tone until released. Then the siren will return to its previous siren tone or standby.
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.
