Wiring the Rumbler 2 in the Vehicle
Connecting the Activation Input
Use 22 AWG wire to connect the white activation lead to the vehicle’s horn ring circuit or user sup-
plied momentary switch.
NOTE:
The R
umbleR
2 only activates by placing the white activation lead to ground. If activation is
required from a 12-volt signal, an installer-supplied relay or a Federal Signal UPKM-3 Module must
be used. The 12-volt signal will energize the relay, and the relay contact will place the white activation
lead to ground.
Connecting Power
The R
umbleR
2 operates only from 12-volt NEGATIVE-grounded vehicle electrical system. There-
fore, before making any electrical connections, determine the polarity of the vehicle’s electrical sys-
tem ground.
BATTERY DRAIN
The Rumbler 2 system does not have an on-off switch. If power for the Rumbler 2 is obtained
directly from the vehicle battery, it draws approximately 0.20 Ah per day in standby mode. If you
are connecting the Rumbler 2 to the switched side of the ignition circuit, make sure the circuit has
enough current capacity to handle the additional 10 A (approx.) load.
FUSE AMPLIFIER AT 12 V SOURCE
Damage to the R
umbleR
2 will occur if it is not properly fused. Ensure that the supplied in-line fuse
holder and 15 A fuse are installed in the red power lead. The R
umbleR
2 should also be fused with
a user supplied 15 A fuse at the 12-volt source.
1. Use a 14 AWG or heavier wire to connect the amplifier’s black ground lead to the vehicle bat-
tery’s negative terminal (–NEG) or ground lug (Figure 2).
2. Use a 14 AWG or heavier wire to connect the amplifier’s red lead to the selected 12-volt source.
