Rotary Switch Operations:
RAD (Radio Repeat) - When the rotary knob is in the RAD posi-
tion, any signal that is received by the vehicle's two-way radio will
be simultaneously broadcast over the vehicle's loudspeaker (the
295HFSA6 must be connected to the two-way radio as outlined in
this manual).
With the Rotary Switch in this Position:
• Pressing the MAN switch will result in SiTest
(See SiTest section)
• Pressing the HORN switch will result in the AIRHORN tone until
the HORN switch is released.
• Activating the HORN RING input results in the AIRHORN tone
until the HORN RING input is released.
• Activating the SIREN SHUTDOWN input has no effect.
• Activating the AUX ENABLE input has no effect.
PA (Public Address) - 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. This position is often the best choice when public
address is required.
With the Rotary Switch in this Position:
.
• Pressing the MAN switch will result in a WAIL tone ramping up
to the peak frequency and ramping down to a stop at the
lowest frequency when the MAN switch is released.
• Pressing the HORN switch will result in the AIRHORN tone
until the HORN switch is released.
• Activating the HORN RING input will result in the AIRHORN
tone until the HORN RING input is released.
• Activating the SIREN SHUTDOWN input has no effect.
• Activating the AUX ENABLE (Or slide switch position 3, if
selected) input will result in a repeating WAIL tone.
