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 familiar with these standards and practices, local codes, and
any special requirements of the authority having jurisdiction.
The speaker can operate at any one of four input power levels (1/4, 1/2, 1, or 2 watts) at either of two input voltages
(25V
or 70.7V
rms
). The rms voltage and power levels are
rms
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. Although they are assembled into a unit at the time of installation, the strobe and speaker are electrically independent
and require separate power sources. Strobes must be powered 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 panels. The strobe CANNOT be supervised when it is attached
to the speaker and is considered a supplementary signaling
device.

Installation
Electrical
Install the electrical wiring in compliance with all applicable 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 attached to the speaker, the speaker and strobe are electrically independent. The speaker must be connected to a
25V
or 70.7V
rms
DC power supply.
Even though V400 series speakers can be used with
25V
or 70.7V
rms
sult if the speaker is improperly connected. Therefore,
be sure to use the COM and 25 terminals when a 25V
amplifier is being used. Similarly, use the COM and 70
terminals if a 70.7V
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.
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/ 2 W, and 1W, respectively.
These posts enable the installer to select any one of four
power levels by installing the plug onto COM and the

Limitations Of Speakers And Speaker/Strobes
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 conditions, 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 not be seen. The electronic visual warning signal
uses an extremely reliable xenon flash tube. It flashes at least once every
three seconds and exceeds current Underwriters Laboratories standards
for private mode viewing. The visual warning signal is suitable for direct
