INSTALLER-SELECTABLE OPTIONS
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 amplifier. 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 front center of the unit. Switch ‘ON’ position is toward the inside of the unit.
SW-1 (AUX_P) Auxiliary Input Polarity - The auxiliary input is normally activated with positive. Turn this switch OFF for negative activation.
SW-2 (INST_ON) Instant ON - The Enable input wiring is normally required to turn on the unit. Turn this switch ON to allow 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.
Siren Tone Disable - All siren tones may be disabled (except Manual, Wail, and Yelp) by turning ON both switches SW-3 and SW-4. Mechanical will be replaced with Wail. Phaser and Horn will be replaced with Yelp.
SW-5 (HRC) Horn Ring Cycler 2 (HRC2) - Turn this switch ON 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-4 (P_I) Phaser Inhibit - Turn this switch on to disable Phaser and Two-Tone.
SW-6 (SM) Short Manual - The Manual siren tone will normally fall and die out when released. Turn this switch ON to have Manual stop immediately.
SW-7 (MECH2) Mechanical Tone 2 - Turn this switch ON for a different mechanical tone sound. (less raspy)
SW-8 (FALL) Mechanical Fall - Turn this switch ON for a quicker mechanical tone fall time.
