The indoor SP and SPV Series are suitable for dry and damp environments. The “K” Series models are suitable for use in both indoor and outdoor applications.
NOTICE: This manual shall be left with the owner/user of this equipment.
The “K” models are suitable for outdoor use in wet environments with outdoor back box supplied with the product.
GENERAL DESCRIPTION
The SpectrAlert Advance series of notification appliances offers a wide range
of speaker/strobe products for wall and ceiling applications, indoors and outdoors. The strobe portion is designed to be used in 12 or 24 volt, DC or FWR
(full wave rectified) systems. The speaker portion can be operated with distribution amplifiers having an output voltage of either 25 or 70.7 volts.
With its low total harmonic distortion, the SpectrAlert Advance SP series offers high fidelity sound output. The SpectrAlert Advance SPV series offers
greater sound output at every tap setting for applications with high ambient
noise levels. The speakers operate at any one of four input power levels. These
products are electrically backward compatible with the previous generation of
SpectrAlert notification appliances. All SpectrAlert Advance products are suitable for use in synchronized systems. The System Sensor MDL3 module may
be used to provide synchronization for the strobes. Wall and ceiling products
may be used interchangeably (wall products may be used on the ceiling and
ceiling products may be used on the wall.) K Series products are designed to
be used over a wider range of temperatures and are suitable for use in wet
SS-140-001 1 I56-3109-011R
locations.
FIRE ALARM SYSTEM CONSIDERATIONS
All wiring must be installed in compliance with the National Electrical Code
(NEC) and applicable local codes. System Sensor recommends installing fire
alarm speakers in compliance with NFPA 72, ANSI/UL1480 and NEC 760.
LOOP DESIGN AND WIRING
The system designer must make sure that the total current drawn by the devices on the loop does not exceed the current capability of the panel supply,
and that the last device on the circuit is operated within its rated voltage. The
current draw information for making these calculations can be found in the
tables within this manual. For convenience and accuracy, use the voltage drop
calculator on the System Sensor website (www.systemsensor.com) or CD-ROM.
When calculating the voltage available to the last device, it is necessary to
consider the voltage drop due to the resistance of the wire. The thicker the
wire, the smaller the voltage drop. Wire resistance tables can be obtained from
electrical handbooks. Note that if Class A wiring is installed, the wire length
may be up to twice as long as it would be for circuits that are not fault tolerant.
NOTE: For 24 volt applications, the total number of strobes on a single NAC
must not exceed 40, with a maximum loop resistance of 120 ohms. For 12 volt
applications, the total number of strobes must not exceed 12, with a maximum loop resistance of 30 ohms.
CAUTION
NOTE: Supply power for strobe must be continuous for proper operation.

ELECTRICAL WIRING
1. Connect the speaker as shown in Figure 1.
NOTE: Do not loop electrical wiring under terminal screws. Wires con-
necting the device to the control panel must be broken at the device
terminal connection in order to maintain electrical supervision.
2. There are two rotary switches on the back of the product The first switch
is used to select either 25 or 70.7 volts input for the speaker portion. The
second switch is used to select the input power of 1/4, 1/2, 1 or 2 watts.
See diagram.
SHORTING SPRING
NOTE: Shorting springs are provided between terminals 2 and 3 and between
terminals 5 and 6 of the mounting plate to enable wiring checks after the
system has been wired, but prior to installation of the final product. These
springs will automatically disengage when the product is installed, to enable
supervision of the final system.

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.

CANDELA SELECTION
Adjust the slide switch on the rear of the product to position the desired candela setting in the small window on the front of the unit. All products meet
the light output profiles specified in the appropriate UL Standards. Use Table 2
to determine the current draw for each candela setting. For K series products
used outdoors at low temperatures, listed candela ratings must be reduced in
accordance with Table 3.
NOTE: SpectrAlert products set at 15 and 15/75 candela automatically work
on either 12V or 24V power supplies. The products are not listed for 12V operating voltages when set to any other candela settings.
