MANUAL / HORN MOMENTARY ROCKER SWITCH
The front panel of the ST160 contains a
momentary rocker switch that operates the
Manual function when the left side is
depressed and the Air Horn when the right
side is depressed.
Manual – Pressing the left side of this momentary rocker switch provides a
generally quicker changing tone when the selector switch is in the Wail, Yelp or
Thunder positions. (See table below). These quicker tones are used at
intersections and very highly congested areas. Pressing the button once changes
to the next faster tone and pressing again changes the tone back to original tone.
With the selector switch in the Manual, PA or Hands Free position this switch
provides a manually activated Wail siren tone while the button is being held.
This is used to momentarily alert motorists or in low noise areas.
Optional operation includes replacement of the Thunder tone with Two-Tone or
disabling the Thunder tone entirely. These options are selected during installation
and may be governed by State or Local laws.

(NOTE: THUNDER and TWO-TONE may be optionally swapped or disabled via
program jumpers. See INSTALLER-SELECTABLE OPTIONS on pages 2-3.)
Air Horn – Pressing the right side of this momentary rocker switch provides a
simulated air-horn tone while pressed. This can be used to either replace, or to
supplement the normal vehicle horn and is useful at intersections or in low noise
areas. This tone will override all other siren tones.
