Connecting to a Remote Control-
Head: (Optional)
This unit may be connected to an existing
control head, such as the Whelen PCCS9NP
or equivalent. This is an optional connection
that enables the WAIL tone to be activated
through the use of a PCCS9NP button or
switch. If this connection is not chosen, cut
the VIOLET wire and cap it to prevent
accidental grounding of the wire.
OPERATING THE CONTROLS:
Power Switch
This switch has two positions: Down (Off) and Up (On). When
this switch is Off, the unit will not function. When the switch is
On, the siren is functional and may be activated at the
operator’s discretion. This switch also activates control head
backlighting. NOTE: If the unit is connected to the vehicle’s
horn ring circuit, the vehicle horn is disabled when the power
switch is in the ON position.
