outlined in this manual).
With the Rotary Switch in this Position:
• Pressing the MAN button will produce the AIRHORN
tone until the MAN switch is released.
• Activating the HORN RING input will produce the
AIRHORN tone until the MAN switch is released.
• Activating the AUX ENABLE input has no effect.
MAN 1 (Manual Siren #1) - When the rotary switch is in this
position the siren is in a standby state where no tones have been
activated, but is waiting for another action to be taken by the
operator.
With the Rotary Switch in this Position:
• Pressing the MAN button will produce the AIRHORN
tone until the MAN switch is released.
• Activating the HORN RING input will produce the
AIRHORN tone until the HORN RING input is released.

Wire Gauge (AWG)
To use this chart...
1. Determine the amount of current being drawn through the wire. Locate this number in the vertical left-hand
column. If the current value is between adjacent values, use the higher number.
2. Follow this row until the length of the installed wire is shown. If the exact length is between adjacent values, use
the higher number. Follow this column upwards to find the recommended size (gage) for this wire.
In the example shown below, the size for a wire with an installed length of 36 feet, through which 22 amps of current
will be drawn, must be determined.
A row for 22 amps is not shown, so the row for 25 amps will be used. Follow this row to the right. A column for 36 feet
is not shown, so the column for 49.5 feet will be used. Following this column to the top will show that the size of this
wire must be at least 6 gage.
