General
The National Fire Protection Association has published
standards and recommended practices for the installation
and use of the appliances described in these instructions. It
is recommended that the installer become familiar with
these standards and practices, local codes, and any special
requirements of the authority having jurisdiction.
The speaker is also equipped with a capacitive input to allow for DC supervision.
An attached 24 VDC strobe at 110, 75, 15, or 15/75 candela
(cd) is also included with the speaker. Although they are
assembled into a unit, the strobe and speaker are electrically independent and require separate power sources.
The speakers can operate at any one of four input power
levels at either of two input voltages. The system voltage
and sound power levels are selected at the time of installation, but can be changed, if necessary.

Strobes can be powered by means of a full-wave rectified
unfiltered supply.

2. See Figure 2. The speaker is equipped with five posts
and an associated plug with red and black wires. The
center post is COM (common) while the others are labeled 2W, 1/4W, 1/2W, and 1W, respectively.
The light output rating of the Model V4R241575ADA is 15
cd (See Figure 1).
The installer selects any one of four input power levels
by installing the plug onto COM and the appropriate
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. Otherwise, permanent
speaker damage could result.
NOTE: The light output at 0° viewing angle for
V4R241575ADA is 75 cd (See Figure 1).
Installation - For Strobe Placement See NFPA 72,
Chapter 6
NOTE: Installation procedure must comply with all applicable local codes and any special requirements of
the authority having jurisdiction.
CAUTION
If the power option plug is not plugged into one of the 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.
Electrical
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.
Mounting
A. General
Both slotted head and Phillips head screws are supplied
with the speaker/strobe. Use the slotted head screw to
mount the device or combination of devices on the electrical box. Use the phillips head screws for attaching accessories to the speaker.
1. Connect the speaker and strobe as shown in Figure 2.
Keep in mind that even though the speaker and strobe
are a single mechanical unit, they are electrically independent - the strobe must be connected to a DC supply
and the speaker to a 25Vrms or 70.7 Vrms amplifier.
Even though V4R24ADA series speakers can be used
with 25 Vrms or 70.7 V rms 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
70.7 terminals if a 70.7 Vrms amplifier is in the system.
The speaker/strobe must be wall mounted so that the
top of the lens is 24 inches below the ceiling.
B. Surface Wall Mount
See Figure 3. Attach the speaker/strobe to a standard 4inch electrical box, using the two 8-32 X 1-7/16" slotted
screws provided. Fill the remaining screws with the
short #8 sheet metal screws, provided.
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 to ensure electrical supervision.

WARNING
The Limitations of Speakers and Speaker/Strobes
and must be installed within an area where it can be seen by building occupants. 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 impaired.
If the power option plug is not plugged into one of the 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 hazard or if placed too far away to be heard over the ambient noise, such as
traffic, air conditioners, machinery, or music appliances that may prevent
alert persons from hearing the alarm. The speaker may not be heard by
persons who are hearing impaired.
The signal strobe may cause seizures. Individuals who have positive
photic response to visual stimuli with seizures, such as persons with epilepsy, should avoid prolonged exposure to environments in which strobe
signals, including this strobe, are activated.
The signal strobe cannot operate from coded power supplies. Coded
power supplies produce interrupted power. The strobe must have an uninterrupted source of DC power in order to operate correctly.
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.
The signal strobe may not be seen. The electronic visual warning signal
uses an extremely reliable xenon flash tube. It flashes at least once every
second and meets the 1971 Underwriters Laboratories standard for the
hearing impaired. The visual warning signal is suitable for direct viewing
