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.
SP100 series speakers 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.
An optional, attached 1.5 or 15 candela (cd) strobe is also available from System Sensor for use with the speaker. 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 full-wave rectified unfiltered supply.
Installation
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.
Electrical
1. Connect the speaker and strobe (if used) as shown in Figure 1. Keep in mind that even though the speaker and optional strobe are a single mechanical unit, they are electrically independent and require separate power sources.
NOTE: Do NOT loop electrical wiring under terminal
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.

screws. Wires connecting the device to the control panel must be broken at the device terminal con­nection in order to maintain electrical supervision.

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 SP100 and SP101 speakers.
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 to the back box. C. Insert the decorative filler plugs (supplied) into the re-
maining two speaker mounting holes.

Strobe Light Ratings
The signaling strobe is rated for 0° to 49°C and is not suit-
able for outdoor use.
See Figure 3. The light output of the SP10**24LO is 1.5 cd
minimum when it is viewed from the front. The light out-
from the front.
Under no circumstances can the strobe input voltage ex­ceed 33 VDC or be less than 18 VDC.
To calculate battery requirements, use the current values shown in Table 2. However, note that there is an in-rush current associated with strobe power-up. This information may be used in consideration of fuse selection.
For the 24V strobe, as shown in Figure 4, the in-rush cur­rent typically peaks at 7.0A, then drops to nominal in 800µS.

WARNING
The Limitations of Speaker/Strobes
If either of the power option jumper wires is not plugged into one of the appropriate option positions, the speaker will not sound and there will be no trouble indication at the panel. Always make sure that the individual speakers are tested after installation per NFPA regulations.
Underwriters Laboratories’ standard 1638 and uses an extremely reliable xenon flash tube.
