General Description
The National Fire Protection Association (NFPA) has published standards and recommended practices for the speakers described in this manual. As a result, the installer must
be familiar with these requirements as well as all local
codes and special requirements of the authority having jurisdiction.
Electrical
1. Connect the speaker/strobe as shown in Figure 1. Keep
in mind that even though the speaker and strobe are a
single mechanical unit, they are electrically independent
and require separate power sources.
NOTE: Do NOT loop electrical wiring under terminal

screws. Wires connecting the device to the control
panel must be broken at the device terminal connection in order to maintain electrical supervision.
SP100ADA series speaker/strobes can be operated with distribution amplifiers having an output voltage of either 25
volts or 70.7 volts.
The speakers operate at any one of six input power levels.
The output sound level is selected at the time of installation, but can be changed, if necessary.
The speaker is also equipped with a capacitive input to allow for DC supervision.
The SP100ADA Series Speaker/Strobe is equipped with an
attached 15, 15/75, 75, or 110 candela (cd), UL 1971 listed
strobe. Although they are shipped as a unit, the strobe and
speaker are electrically independent and require separate
power sources. Strobes can be powered by means of a 24V
regulated or full-wave rectified unfiltered supply.
Installation - For Strobe Replacement See NFPA 72,
Chapter 6
All wiring must be installed in compliance with the National Electrical Code and all applicable local codes as well
as any special requirements of the authority having jurisdiction, using the proper wire size. This also includes all
applicable NFPA Standards, ANSI/UL 1480, and NEC 760.
2. Notice that the speaker circuit board is equipped with
two sets of posts and associated electrical jumper wires.
One set of posts is numbered 1 through 6 while the other
is labeled A and B. Both electrical leads are fitted with a
barrel connector. These two sets of posts and leads enable the installer to select any one of six sound pressure
levels with either a 25 volt or 70.7 volt amplifier.
Figure 1. Electrical connections:
D400-55-00 1 I56-691-03
For example, Table 1 shows that to select a 1/4 Watt in-
put when a 25 volt amplifier is being used, slide the blue
lead onto post 3 and slide the yellow lead onto post B.
Similarly, to select a 4 Watt input with a 70.7 volt amplifier, slide the blue and yellow leads onto posts 2 and A,
respectively.
Table 1 also lists the UL reverberant and anechoic output
sound levels for each transformer power tap on the
SP100ADA Series Speaker/Strobes.
CAUTION
Signal levels exceeding 130% rated signal voltage can damage the speaker. Consequently, an incorrect tap connection
may cause speaker damage. This means that if a 25V tap is
selected when a 70.7V amplifier is being used, speaker
damage may result. Therefore, be sure to select the proper
taps for the amplifier voltage/input power level combination being used.
NEVER connect the yellow jumper to the posts numbered 1
through 6 or the blue jumper to lettered posts A or B.
Mechanical
Slotted head screws are included for attaching the speaker
to the electrical junction box. Insert the decorative filler
plugs supplied into the remaining two holes in the grille.

Mounting
See Figure 2. The speaker can be flush mounted on a 4" X
4" X 2-1/8" back box with a 1-1/2" extension ring, as follows:
A. Select the appropriate pair of diagonally opposite
mounting holes in the speaker grille.
B. Use the two 8-32 X 1-3/4" slotted pan head screws, pro-
vided, to attach the speaker/strobe to the back box.
C. Insert the decorative filler plugs (supplied) into the re-
maining two speaker mounting holes.
