Connecting the e-Q2B to the Rumbler 2 Low Frequency Amplifier
The e-Q2B has a Rumbler audio output that enables it to interface to a Federal Signal Rumbler 2
siren amplifier. The Rumbler 2 intersection-clearing system uses the output of the e-Q2B siren
amplifier to synthesize a low frequency signal. It then amplifies the signal to drive a Federal Signal
low-frequency siren speaker. Low frequency tones have the distinct advantage of penetrating solid
materials, enabling vehicle operators and nearby pedestrians to feel the sound waves.
Figure 3.9 on page 25 shows the connections between the Rumbler 2 and the e-Q2B siren amplifier.

Amplifier,” document number 2562420, Rev. B or later.
Enabling the Horn-Ring Transfer of Siren Tones
The e-Q2B horn-ring transfer function uses the vehicle horn switch to toggle between siren tones.
For more information on how this function operates, see “Horn Ring” on page 46 for the standard
e-Q2B Siren System. For the e-Q2B-CAL Siren system, see “Horn Ring” on page 50.
NOTE:
The 12-position tension-clamp connector accepts 18 AWG to 22 AWG wire. The
recommended length of insulation to strip from the wires for insertion into the connector is
0.275 in (0.7 mm).
To enable the horn-ring control of siren tones:
1.
Locate the vehicle horn relay.
2.
Route wire from the
RING
and
HORN
connectors on the front of the siren amplifier to the
relay (Figure 3.10 on page 27). If possible, follow the factory wire harness to the relay.
3.
Locate and cut the wire that connects the vehicle horn to the horn relay.
4.
Terminate the lead from the horn relay in the
RING
connector on the siren amplifier.
5.
Terminate the lead from the vehicle horn in the
HORN
connector on the siren amplifier.
6.
Insulate the spliced leads with twist-on wire connectors. Fold and seal unused leads.
7.
To prevent fretting or disconnection, tighten the two screws on the 12-position connector.
