OPTION SWITCHES			SIDE VIEW
An internal 8-position DIP switch on the circuit	COVER REMOVED
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	OPTION SWITCHES
unit. The chassis will slide out the front.
Adjusting Option Switches - the DIP Switch is located on
		8 7 6 5 4 3 2 1
the internal PCB assembly board toward the right side of
the unit. Switch 1 is toward the back of the unit. Switch	ON
‘ON’ position is toward the inside side of the unit.
				Default Setting Shown
				SW-7 and SW-8 ON

SW-1Two-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-3	SW-4	Siren push-button and Auxiliary Input Function
		with Rotary Selector Switch in Standby
OFF	OFF	(Default) Produces Horn tone while pressed.
ON	OFF	Manual control of Mechanical tone.
		Also Mechanical tone continues to fall when Rotary Selector
		Switch is changed from Mechanical Position.
OFF	ON	Manual control of Wail tone.
ON	ON	Activates Horn Ring Cycler 2 (HRC2) function.

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.

SW-6	SW-7	SW-8	Auxiliary Input Activation Polarity
ON	OFF	OFF	Positive and Negative Activation (Traditional Auxiliary)
OFF	ON	ON	Positive Only Activation (Factory Default)
OFF	ON	OFF	Negative Only Activation

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.
