Connecting Speakers to the e-Q2B
SOUND HAZARD—All effective sirens and horns produce loud sounds
produce loud sounds (120 dB) that may cause permanent hearing loss.
Always minimize your exposure to siren and horn sounds and wear hearing
protection. Do not sound the siren or horn indoors or in enclosed areas where
you and others will be exposed to the sound.
SPEAKER CONNECTIONS—For proper operation and performance, always
connect the speakers in parallel and in phase.
The Model e-Q2B-200 operates one 200-watt speaker or two 100-watt speakers with an impedance
of 11 ohms. The Model e-Q2B-100 operates one 100-watt speaker with an impedance of 11 ohms.
The e-Q2B-200 siren amplifier is designed to operate optimally with a Federal Signal BP200-Q
or BP200-EF 200-watt speaker system, which is not included as part of the electronic siren. This
speaker system incorporates two 11-ohm, 100-watt neodymium drivers to produce a full 200 watts
of output. If you are using a speaker system comprising two 11-ohm, 100 W speakers, connect the
speakers as shown in Figure 3.6 on page 22.
Federal Signal speakers are weatherproof and may be installed in any unobstructed convenient
location: on the fender, behind the grill, etc. Any special mounting instructions applicable to the type
of speaker you have chosen will be found in the speaker carton.
A 20-foot speaker cable is included with Federal Signal BP200 Series speakers. The cable has a
waterproof connector on one end that connects to the speaker. The other end of the cable is supplied
un-terminated.
Connecting the BP200 Speaker to the e-Q2B-200
To connect the 200-watt speaker system to the Model e-Q2B-200 siren amplifier:
1.
Mount the e-Q2B Siren System components according to the instructions included with
each product.
2.
Connect the waterproof connector to the speaker and route the speaker cable through the
vehicle compartment to the amplifier.
3.
Carefully strip back the outer jacket on the speaker cable to expose the four colored
conductors.
4.
Use 18 AWG or thicker wire to extend and connect the speaker leads.
5.
Terminate the conductors in the supplied four-position connector that mates with the
SPEAKER OUTPUT
terminal block of the amplifier as shown in Figure 3.6.
6.
To prevent fretting or disconnection, tighten the two screws on the four-position speaker
connector.
