General Description
The SpectrAlert series notification appliances are designed to meet the
requirements of most agencies governing these devices, including: NFPA,
ADA, The National Fire Alarm Code, UL, FM, CSFM, MEA. Also, check
with your local Authority Having Jurisdiction for other codes or standards
that may apply.
The SpectrAlert series can be installed in systems using 12- or 24-volt pan-
els having DC or full-wave rectified (FWR) power supplies. The series can
also be installed in systems requiring synchronization (module MDL
required) or systems that do not require synchronization (no module
required).
NOTICE: This manual shall be left with the owner/user of this equipment.
Fire Alarm System Considerations
Temporal and Non-Temporal Coded Signals:
The American National Standards Institute and the National Fire Alarm
Code require that all horns used for building evacuation installed after July
1, 1996, must produce Temporal Coded Signals.
Signals other than those used for evacuation purposes do not have to pro-
duce the Temporal Coded Signal. Temporal coding is accomplished by inter-
rupting a steady sound in the following manner:
Power Supply Considerations
Panels typically supply DC filtered voltage or FWR (full-wave rectified)
Specifications
Voltage Range: DC or Full-Wave Rectified
Horn: 10.5 to 30 Volts
Strobes & Horn/Strobes: 12-volt models –10.5 to 17 volts; 24-volt models –20 to 30 volts
(with MDL module): 12-volt models –11 to 17 volts; 24-volt models –21 to 30 volts
NOTE: Horn and combo units will operate on walk tests with on-time durations of 1 sec. or greater.
Flash Rate: 1 Flash Per Second
Operating Temperature: 32°F to 120°F (0°C to 49°C)
K Series: Horn and horn/strobe models are indoor listed, having a temperature range of 32°F to 150°F (0°C to 66°C) and are
Rainproof per UL50 (NEMA 3R).
Strobe only models have a temperature range of –40°F to 158°F (–40°C to 70°C), and are indoor/outdoor listed per
UL1638 and indoor listed per UL1971. The S24110K is rated 60 candela @ –40°C. S2475K and S241575K are rated 41
candela @ –40°C.
Light Output: Models with 15 only in the model number are listed at 15 candela
Models with 1575 are listed at 15 candela per UL 1971 but will provide 75 candela on axis (straight ahead)
Models with 30, 75 or 110 are rated for that candela.
Models with a red, amber, green or blue lens are listed at 75 candela per UL 1638.
Sound Output: Sound output levels are established at Underwriters Laboratories in their reverberant room. Always use the sound out-
put specified as UL Reverberant Room when comparing products.
Listings: UL, FM, CSFM, MEA. K Series models are UL, CSFM, MEA listed only.
Note: For clear lens models only, as tested by UL (reference revised 1971 STD, sections/paragraphs 27A.1-27A.5 and 48.4), the maximum number of
synchronous strobe lights that can be connected to the MDL synch module is 70. The maximum impedance between the adjacent units is 250 ohms.
voltage. The system design engineer must calculate the number of units
used in a zone based on the type of panel supply. Be certain the sum of all
the device currents do not exceed the current capability of the panel.
Calculations are based on using the device current found in the subsequent
charts and must be the current specified for the type of panel power sup-
ply used.
Wire Sizes
The designer must be sure that the last device on the circuit has sufficient
voltage to operate the device within its rated voltage. When calculating
the voltage available to the last device, it is necessary to consider the volt-
age drop due to the resistance of the wire. The thicker the wire, the less
the voltage drop. Generally, for purposes of determining the wire size nec-
essary for the system, it is best to consider all of the devices as “lumped”
on the end of the supply circuit (simulates “worst case”).
Typical wire size resistance:
18 AWG solid: Approximately 8 ohms/1,000 ft.
16 AWG solid: Approximately 5 ohms/1,000 ft.
14 AWG solid: Approximately 3 ohms/1,000 ft.
12 AWG solid: Approximately 2 ohms/1,000 ft.
Example: Assume you have 10 devices on a zone and each requires 50 mA
average and 2000 Ft. of 14 AWG wiring (total length=outgoing +return).
The voltage at the end of the loop is 0.050 amps per device x 10 devices
x 3 ohms/1,000 ft. x 2000 ft =3 volts drop.
Note: If class “A”wiring is installed, the wire length may be up to 4 times
the single wire length in this calculation.

The same number of devices using 12 AWG wire will produce only 2 volts
drop. The same devices using 18 AWG wire will produce 8 volts
drop.Consult your panel manufacturer’s specifications, as well as
SpectrAlert’s operating voltage range to determine acceptable voltage
drop.
Horn Selections
Horns are factory set for high volume, temporal code, and electromechan-
ical tone.
Tones:
Two tones may be selected using the jumper plugs located on
the printed circuit board. With the jumper offset, the tone is the
Electromechanical sound. With the jumper in place, the tone is
a 3 kHz sound.
NOTE: When powered from FWR supply, tones will be modulated (turned
on and off) by 120Hz causing the tones to sound different from DC power.
Temp/Non-Temp:
Temporal coding or Non-Temporal coding can be selected using
the jumper plugs located on the printed circuit board. With the
jumper offset, the tone pattern is the Temporal Coded Signal.
With the jumper in place, the Non-Temporal code (continuous)
tone is active.
High/Low Volume:
High or low volume may be selected using the jumper plugs locat-
ed on the printed circuit board. With the jumper in place, the
sound output level is the high level. With the jumper offset, the
sound output level is the low level. The low volume setting must
NOT be used when the device is powered from a 12-volt panel.
NOTE: Always power down devices before setting jumpers.

The horn and/or strobe will not work without power. The horn/strobe
gets its power from the fire/security panel monitoring the alarm system.
If power is cut off for any reason, the horn/strobe will not provide the
desired audio or visual warning.
The horn may not be heard. The loudness of the horn meets (or exceeds)
current Underwriters Laboratories’standards. However, the horn may not
alert a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. The horn 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 horn may not be heard by persons who are hearing impaired.
NOTE: Strobes must be powered continuously for horn operation.
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 dis-
regarded or not seen. The strobe may not be seen by the visually impaired.
The signal strobe may cause seizures. Individuals who have positive
photic 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 unin-
terrupted source of power in order to operate correctly. System Sensor rec-
ommends that the horn and signal strobe always be used in combination
so that the risks from any of the above limitations are minimized.
