GENERAL DESCRIPTION

The SpectrAlert Advance series of notification appliances offers a wide range
of horns, strobes, and horn/strobes, for wall and ceiling applications, indoors
and outdoors. They are designed to be used in 12 or 24 volt, DC or FWR
(full wave rectified) systems. These products are electrically backward compat­ible with the previous generation of SpectrAlert notification appliances. Horn/
strobe products are available in two versions. The 2-wire products fit systems
where a single NAC controls both horn and strobe. The 4-wire products are in­tended for systems which have separate wiring circuits for the horn and strobe.
All SpectrAlert Advance products are suitable for use in synchronized systems.
The System Sensor MDL module may be used to provide synchronization.

K Series products are designed to be used over a wider range of temperatures
and are suitable for use in wet locations.

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.)

FIRE ALARM SYSTEM CONSIDERATIONS

The National Fire Alarm Code, NFPA 72, requires that all horns, used for
building evacuation produce temporal coded signals. Signals other than those
used for evacuation purposes do not have to produce the temporal coded sig­nal. System Sensor recommends spacing notification appliances in compli­ance with NFPA 72.

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: The total number of strobes on a single NAC must not exceed 40 for
24 volt applications or 12 for 12 volt applications. Loop resistance on a single
NAC should not exceed 120 ohms for 24 volt and 30 ohms for 12 volt systems.

For 4-Wire installations, terminals 1, 2, and 3 connect to the strobe; terminals
4 and 5 connect to the horn. The horn and strobe circuits must be wired in­dependently, and each circuit must be terminated with the appropriate EOL
device. Removal of a notification device will result in an open circuit indica­tion on the strobe loop.

SHORTING SPRING

A0368-00

NOTE: A shorting spring is provided between terminals 2 and 3 of the mount­ing plate to enable wiring checks after the system has been wired, but prior
to installation of the final product. This spring will automatically disengage
when the product is installed, to enable supervision of the final system.

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. For K series
products used outdoors at low temperatures, listed candela ratings must be re­duced in accordance with Table 2. Use Table 1 to determine the current draw
for each candela setting. WIRING DIAGRAMS

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. For 4-Wire products,
total current draw may be determined by adding current draw for the specific
candela selection in Table 1 with the current draw for the specific horn selec­tion in Table 3.

HORN SELECTION

Turn the rotary switch on the back of the product to the desired setting. For
horn and 4-wire horn/strobe products, the current draw for each setting is
listed in Table 3. For 2-wire horn/strobe products (P2 series), current draws
are listed in Tables 4 and 5. The sound output measurement for each horn
setting is shown in Table 6.

NOTE: In positions 7, 8, and 9, temporal coding must be provided by the NAC.
If the NAC voltage is held constant, the horn output will remain constantly on.
Positions 7, 8, and 9 are not available on 2-wire horn/strobe products.
