V4R241575ADA is 75 cd (See Figure 1).
Installation - For Strobe Placement See NFPA 72,
Chapter 6
NOTE:
Installation procedure must comply with all appli-
cable local codes and any special requirements of
the authority having jurisdiction.
Electrical
All wiring must be installed in compliance with the Na-
tional Electrical Code and all applicable local codes as well
as any special requirements of the authority having juris-
diction, using the proper wire size. This also includes all
applicable NFPA Standards, ANSI/UL 1480, and NEC 760.
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 inde-
pendent - the strobe must be connected to a DC supply
and the speaker to a 25V
rms
or 70.7 V
rms
amplifier.
Even though V4R24ADA series speakers can be used
with 25 V
rms
or 70.7 V
rms
amplifiers, permanent damage
can result if the speaker is improperly connected. There-
fore, be sure to use the COM and 25 terminals when a 25
V
rms
amplifier is being used. Similarly, use the COM and
70.7 terminals if a 70.7 V
rms
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 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 la-
beled 2W, 1/4W, 1/2W, and 1W, respectively.
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.
CAUTION
If the power option plug is not plugged into one of the op-
tion 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.
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 elec-
trical box. Use the phillips head screws for attaching ac-
cessories to the speaker.
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 4-
inch 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.
