NOTICE: This manual shall be left with the owner/user of this equipment.
GENERAL DESCRIPTION
The SpectrAlert Advance low frequency series of notification appliances offers
a range of low frequency sounder and low frequency sounder/strobe products
for wall and ceiling applications. Studies have shown that low frequency audible devices that operate around 520Hz are more effective in waking individuals
in sleeping areas. The sounder only version is designed for use in 12 or 24 volt,
DC or FWR (full wave rectified) systems. Sounder/Strobe versions are only
to be used with 24 volt, DC or FWR systems. These products are electrically
backward compatible with the previous generation of SpectrAlert notification
appliances. The 2-wire products fit systems where a single NAC controls both
sounder and strobe. The System Sensor MDL3 module may be used to provide
synchronization.
Models are approved for wall and ceiling installations.
FIRE ALARM SYSTEM CONSIDERATIONS
The National Fire Alarm Code, NFPA 72, requires that all sounders, 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. The National Fire Alarm Code, NFPA 72, will require effective Jan. 1, 2014
that audible appliances installed in sleeping areas produce a low frequency
alarm signal that shall be a square wave or provide equivalent awakening ability. 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 (systemsensor.com/volt).
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.
The sounder 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.
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.

1. Attach mounting plate to junction box as shown in Figures 3 and 4. The
mounting plate is compatible with 4-inch square, double gang, and 4-inch octagon junction boxes (2-wire products may be used with a single gang box).
2. Connect field wiring to terminals, as shown in Figures 1 .
3. If the product is not to be installed at this point, use the paint cover to
prevent contamination of the mounting plate. (For indoor models only)
4. To attach product to mounting plate, remove the paint cover, then hook
tabs on the product housing into the grooves on mounting plate.
5. Then, swing product into position to engage the pins on the product with
the terminals on the mounting plate. Make sure that the tabs on the back
of the product housing fully engage with the mounting plate.
6. Secure product by tightening the single mounting screw in the front
of the product housing. For tamper resistance, the standard captivated
mounting screw may be replaced with the enclosed Torx screw.
SURFACE MOUNT BACK BOX MOUNTING
1. The surface mount back box may be secured directly to the wall or ceiling. Grounding bracket provided if needed.
2. The wall mount box must be mounted with the up arrow pointing up.
3. Threaded knockout holes are provided for the sides of the box for ¾ inch
and ½ inch conduit adapter. Knockout plugs in the back of the box can
be used for ¾ inch and ½ inch rear entry.
4. To remove the ½ inch knockout, we recommend you use a flat head
screwdriver and place the blade along the inner edge and work your way
around the knockout as you strike the screwdriver, as shown in Figure
7. To remove the ¾ inch knockout place the blade of the screwdriver
along the edge and work your way around the knockout as you strike the
screwdriver, as shown in Figure 8.
5. V500 and V700 wiremold raceways are also provided. Use V500 for low
profile applications and V700 for high profile applications.
6. To remove the wire mold knockout turn pliers up, as shown in Figure 9.
7. Attach the mounting plate to the surface mount back box using the four
unpainted screws, as shown in Figure 5 or 6.
8. Follow steps 2-6 of the mounting indoor wall or ceiling products to wire
and attach the product.

Please refer to insert for the Limitations of Fire Alarm Systems
THE LIMITATIONS OF LOW FREQUENCY HORN/STROBES
The sounder and/or strobe will not work without power. The sounder/strobe gets its
power from the fire/security panel monitoring the alarm system. If power is cut off for
any reason, the sounder/strobe will not provide the desired audio or visual warning.
The sounder may not be heard. The loudness of the sounder meets (or exceeds) current Underwriters Laboratories’ standards. Studies have shown that the low frequency
sounder (520Hz) is more effective at waking individuals in sleeping spaces, especially
individuals that may have recently used drugs or drinking alcoholic beverages. The
sounder 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 low frequency sounder may not be heard by persons who are hearing impaired.
NOTE: Strobes must be powered continuously for sounder operation.

representative, dealer, or employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s obligation of this Warranty
shall be limited to the replacement of any part of the product which is found to be defective in materials or workmanship under normal use and service during the three year
period commencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization number, send defective units postage prepaid to: System Sensor, Returns Department, RA #__________, 3825
FCC STATEMENT
SpectrAlert Strobes and Low Frequency Sounder/Strobes have been tested and found
to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment

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. 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.
The signal strobe may cause seizures. Individuals who have positive photoic 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 power in
order to operate correctly. System Sensor recommends that the sounder and signal strobe
always be used in combination so that the risks from any of the above limitations are
minimized.

for any consequential or incidental damages for breach of this or any other Warranty,
expressed or implied whatsoever, even if the loss or damage is caused by the Company’s
negligence or fault. Some states do not allow the exclusion or limitation of incidental or
consequential damages, so the above limitation or exclusion may not apply to you. This
