General Description
The National Fire Protection Association (NFPA) has pub-
lished standards and recommended practices for the speak-
ers 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 ju-
risdiction.
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 installa-
tion, but can be changed, if necessary.
The speaker is also equipped with a capacitive input to al-
low for DC supervision.
An optional, attached 1.5 or 15 candela (cd) strobe is also
available from System Sensor for use with the speaker. Al-
though 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.

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
screws. Wires connecting the device to the control
panel must be broken at the device terminal con-
nection in order to maintain electrical supervision.
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 Aand B. Both electrical leads are fitted with a
barrel connector. These two sets of posts and leads en-
able the installer to select any one of six sound pressure
levels with either a 25 volt or 70.7 volt amplifier.

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 3and slide the yellow lead onto post B.
Similarly, to select a 4 Watt input with a 70.7 volt ampli-
fier, slide the blue and yellow leads onto posts 2and 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 dam-
age 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 combina-
tion being used.
NEVER connect the yellow jumper to the posts numbered 1
through 6 or the blue jumper to lettered posts Aor 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 fol-
lows:
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-
put of the SP10**24M is 15 cd minimum when it is viewed
from the front.
Under no circumstances can the strobe input voltage ex-
ceed 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 cur-
rent typically peaks at 7.0A, then drops to nominal in
800µS.

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.
The speaker may not be heard. The loudness of the speaker meets (or
exceeds) the current Underwriters Laboratories’ standards. However, the
speaker may not attract the attention of a sound sleeper or one who has
recently used drugs or has been drinking alcoholic beverages. The speaker
may not be heard if it is placed on a different floor from the person in haz-
ard or if placed too far away to be heard over the ambient noise. Traffic, air
conditioners, machinery, or music appliances may prevent even alert per-
sons from hearing the alarm. The speaker may not be heard by persons
who are hearing impaired.
The Signal Strobe may not be seen. The electronic visual warning signal
that flashes at least once every three seconds meets or exceeds current
Underwriters Laboratories’ standard 1638 and uses an extremely reliable
xenon flash tube. The visual warning signal is suitable for direct viewing
and must be installed within an area where it can be seen by building oc-
cupants. The strobe must not be installed in direct sunlight or areas of
high light intensity (over 60 foot candles) where the visual flash might be
disregarded or not seen. The strobe may not be seen by the visually im-
paired and is NOT intended to meet American Disabilities Act (ADA) re-
quirements.
The signal strobe may cause seizures. Individuals who have positive
photic response to visual stimuli with seizures, such as persons with epi-
lepsy, should avoid prolonged exposure to environments in which strobe
signals, including this strobe, are activated.
System Sensor recommends that the speaker and signal strobe always be
used in combination so that the risks from any of the above limitations are
minimized.

V400R (Red), V400B (Beige) Speakers for
Fire Protective Signaling Systems and
Strobes SS12LO, SS24LO, SS24LOC,
SS24M, and SS24MC for these Speakers
INSTALLATION AND MAINTENANCE INSTRUCTIONS
A Division of Pittway
3825 Ohio Avenue, St. Charles, Illinois 60174
1-800-SENSOR2, FAX: [phone]
General Description
The National Fire Protection Association has published
standards and recommended practices for the installation
and use of the appliances described in these instructions.
System Sensor recommends that the installer become fa-
miliar with these standards and practices, local codes, and
any special requirements of the authority having jurisdic-
tion.
The speaker can operate at any one of four input power lev-
els (1/4, 1/2, 1, or 2 watts) at either of two input voltages
(25Vrms or 70.7Vrms ). The rms voltage and power levels are
selected at the time of installation, but can be changed, if
necessary.
The speaker is equipped with a capacitive input to allow
for DC supervision.
Optional strobes are available for use with the speaker. Al-
though they are assembled into a unit at the time of instal-
lation, the strobe and speaker are electrically independent
and require separate power sources. Strobes must be pow-
ered by means of an uncoded full-wave rectified, filtered or
unfiltered supply. Model SS12LO is for use with 12 volt
panels and Models SS24LO and SS24M are for 24 volt pan-
els. The strobe CANNOT be supervised when it is attached
to the speaker and is considered a supplementary signaling
device.
Specifications
Voltage Input: 25 Vrms or 70.7 Vrms
Input Power Taps: 1/4 Watt, 1/2 Watt, 1 Watt, or 2 Watts
Frequency Range: 400 to 4000 Hz
Supervision: Capacitive input for supervisory DC voltage
Grille Size: 4" X 4"
Cone Material: Weather resistant
Mounting: Standard 4" X 4" electrical box
Surface mount directly to box
Semiflush mount, using model MP-SF or MP-SFB (red or beige)

SS24MC Strobes (optional) for ceiling-mounted installations.
Input Terminals: 14 to 18 AWG
Operating Temperature Range: 32°to 120°F
Installation
Electrical
Install the electrical wiring in compliance with all appli-
cable local codes as well as any special requirements of the
authority having jurisdiction, using the proper wire size.
1. Connect the speaker and strobe as shown in Figure 1.
Keep in mind that if an optional strobe has been at-
tached to the speaker, the speaker and strobe are electri-
cally independent. The speaker must be connected to a
25Vrms or 70.7 Vrms amplifier and the strobe to an
uncoded DC power supply.
Even though V400 series speakers can be used with 25
Vrms or 70.7 Vrms amplifiers, permanent damage can result
if the speaker is improperly connected. Therefore, be
sure to use the COM and 25 terminals when a 25 Vrms
amplifier is being used. Similarly, use the COM and 70
terminals if a 70.7 Vrms amplifier is in the system.
NOTE: Do NOT loop electrical wiring under terminal
screws. Wires connecting the device to the control
panel must be broken at the device terminal con-
nection to ensure electrical supervision.
2. See Figure 1. The speaker is equipped with five posts
and an associated plug with red and black wires. The
center post is labeled COM (common) while the others
are labeled 2W, 1/4W, 1/2W, and 1W, respectively.
These posts enable the installer to select any one of four
power levels by installing the plug onto COM and the ap-

propriate power post. When connecting this plug, make
sure the black wire is connected to the COM post and
the red wire to the numbered post.
NOTE: The plug MUST be installed for the speaker to oper-
ate. The speaker cannot sound or produce a trouble
indication at the panel if the plug is not installed.
Mounting
NOTE: The descriptions in this section assume that all prepa-
rations necessary for the installation of the speakers
have been completed. This includes the installation
of all conduit, electrical boxes, and wiring.
A. General
Both slotted head and phillips head screws are supplied
with the speaker/strobe. Use the slotted head screws to
mount the device or combination of devices on the electri-
cal box. Use the phillips head screws in the two remaining
holes when only a speaker is being installed.
B. Surface Mount
1. Speaker Only (Figure 2)
(a) Wire the speaker as described in Electrical.
(b) Attach the speaker to a standard 4-inch electrical
box, using the two 8-32 X 1-7/16 slotted screws pro-
vided. Fill the remaining holes with the short #8
sheet metal screws.
2. Speaker with Strobe ( Figure 3)
(a) Use a small bladed screwdriver to remove the plastic
flash from the two strobe lug slots on the speaker.
(b) Identify the two diagonally opposite speaker holes
that will be needed for mounting the speaker on the
electrical box. The other two holes will be used to
attach the strobe and flush mount plate to the
speaker.
(c) Position the strobe over the speaker and guide its
two power lugs into the slots formed when the flash
was removed in step 2(a). Attach the strobe and
flush mount plate to the speaker using #8 phillips
head sheet metal screws through the pair of strobe
mounting holes that was selected in step 2(b).
(e) Slide the right angle connector on the red wire onto
the strobe power lug nearest the “F” in “FIRE”. Simi-
larly, connect the right angle connector on the black
wire to the remaining lug on the opposite side of the
speaker.
(f) Connect the free end of the red wire to the STROBE
+ terminal (1) and black wire to STROBE – (5).
Then, connect a source of uncoded (continuous) 12
VDC or 24 VDC, as appropriate for the strobe model,
