LINE
Lighting Control: The WPA TM series control head offers a BLACK/WHITE
low-current control line that wire provides 12VDC / 250ma. This wire is activated
when the “Siren/Lights Siren” toggle switch on the control head is moved to the
“Lights Siren” position. In the “Siren” position this wire is disabled (Fig. 8).
Wiring for the BETA2 TM Control Head: The BETA2 Series Control
Head is not provided with the waterproof AMPSEAL plug connector. It is an
automotive application and has been designed for an automotive amplifier
(BETA112R). A 9-position female connector is provided with the BETA2. After
routing the contact wires to the amplifier, take the 9-position female connector
and insert it into the 9-position male connector located on the BETA
amplifier
(see Fig. 9 below for 9-position wire details).

The installation of your control head will be complete after the fuse block wire of the remote amplifier is connected to the POSITIVE
(+) terminal of the battery. After this connection has been made, inspect the fuses of the amplifier and at the battery. If either of these
fuses is blown, carefully inspect all of the circuit wires and make sure they are wired correctly. Replace the blown fuses with ones of
an identical amp rating. If these fuses blow after installation or activation, contact Whelen Engineering Technical Support.

Before the wires can be inserted into their sockets, you must first release the
Internal Wedge Lock. To do this you must bend both ears out slightly, while at
the same time, sliding the center piece (shown in white) out no more than 1/4”.
This will release the internal wedge lock. After inserting the wires, slide the
center piece back in to close the internal wedge lock. NOTE: Be careful not to
bend the ears too far out as they might break off.
