To use this feature, connect a user-supplied, 18-gauge wire to position 7 of the eleven-
position connector. Connect the other end of the wire to a vehicle circuit that is,
depending on the vehicle, grounded or connected to battery positive (+) when the
vehicle is shifted into Park. See Figure 1 on page 13.
Aux Out
NOTE:
This output is activated any time the siren is operating in Wail, Yelp, or Priority
mode.
This feature can be used to activate an external relay (200 mA maximum) for
controlling warning lights.
To use this feature, connect a user-supplied, 18-gauge wire to position 8 of the
eleven-position connector as shown in Figure 1 on page 13.
Ground
Connect a user-supplied, 18-gauge black wire to position 9 of the eleven-position
connector. Connect the other end of the wire to the negative battery terminal.
Ignition
Connect a user-supplied, 18-gauge wire to position 11 of the eleven-position
connector. Connect the other end of the wire to a vehicle circuit that is powered when
the ignition switch is “on.”
Horn Ring Cable
The horn ring cable assembly, located in the accessory kit, is a four-wire cable
terminating in an orange edge connector. This connector should be installed on the
mating four-pin connector (J2) located on the Control Head PC board, and should
be oriented so that the white wire is closest to the RJ45 phone jack. The following
paragraphs describe the installation of the leads at the other end of the horn ring
cable.
Horn Ring
The horn ring transfer circuit of the siren is capable of switching a maximum
of 10 amperes.
NOTE:
An external relay is not required for horn ring operation.
If the horn ring will not be used to control siren operation, fold back and insulate the
white and white/yellow wires in the power cable and disregard the procedure in this
paragraph. However, in order to utilize the Tap II and horn ring controlled Air Horn
features of the siren, the following procedure must be performed.
1.
Locate the wire that connects the vehicle horn ring switch to the horn or horn
relay. Cut this wire.
