OPTION SWITCHES
An internal 8-position DIP switch on the circuit board may be changed to select various options.
Accessing Option Switches - the DIP switch is located just behind the front panel of the ampli-
fier. Use a 7/64” allen wrench to remove the 4 corner screws then remove front panel.
Adjusting Option Switches - it is easiest to view the DIP
switch with the unit turned upside down. With the unit
upside down, the DIP Switch is located on the internal
PCB assembly board toward the left side of the unit.
Switch 1 is toward the front of the unit. Switch ‘ON’ posi-
tion is toward the left side of the unit.
The default setting is shown here. Switch 1 is on.
SW-1 (AUX_P) Auxiliary Input Polarity - The auxiliary input is normally activated with positive.
Turn switch off for negative activation.
SW-2 (INST_ON) Instant ON - The Enable input wiring is normally required to turn on the unit.
Turning this switch on allows the front panel switches to instantly turn on the unit.
(SC-1002 and SC-1012 only)
SW-3 (T-T) Two-Tone - Turn this switch on to replace Phaser with Two-Tone.
SW-4 (H_I) Horn Inhibit - Turn this switch on to disable Horn tone. Horn will be replaced with
Yelp.
SW-3 and 4 Tone Disable - All siren tones may be disabled except Manual, Wail and Yelp by
turning on both switches. Mechanical will be replaced with Wail. Phaser and Horn will be re-
placed with Yelp.
SW-5 (HRC) Horn Ring Cycler 2 (HRC2) - While the siren is in standby, the auxiliary input can
cycle through Mechanical, Wail, Yelp, and Phaser tones by repeatedly activating the auxiliary
input. Turn this switch on for HRC2 feature. See OPERATION section for further details.
