General Description
The SpectrAlert Advance series of notification appliances
offers a comprehensive range of red and white wall, ceiling,
and outdoor products including horns, strobes, and horn/
strobes. These products are electrically backward compatible with the previous generation of notification appliances.
While there are products specifically designed for use on
the ceiling or the wall, the products are listed to be used
in either application, i.e., wall products could be used on
the ceiling. SpectrAlert products are designed to be used
in either 12 or 24 volt DC or full wave rectified (FWR) systems. If required, the MDL module may be used in order to
provide synchronization.
NOTICE: This manual shall be left with the owner/user of
this equipment.
Fire Alarm System Considerations
The National Fire Alarm Code, NFPA 72, requires that all
horns, used for building evacuation installed after July 1,
1996, produce temporal coded signals. Signals other than
those used for evacuation purposes do not have to produce
the temporal coded signal.
Power Supply Considerations
Panels typically supply DC filtered voltage or FWR (full
wave rectified) voltage. The system design engineer must
calculate the number of units used on a loop based on the
type of panel supply. Be certain the sum of all the device
currents does not exceed the current capability of the panel.
D690-03-00 1 I56-2769-003R
Calculations are based on using the device current found
in the subsequent charts and must be compatible with the
current specified for the panel or power supply 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 voltage drop due to
the resistance of the wire. The thicker the wire, the smaller
the voltage drop. Generally, for purposes of determining the
wire size necessary for the system, it is best to consider all
of the devices as “lumped” on the end of the supply circuit
to simulate worst case. For the most accurate voltage drop
calculations use the System Sensor voltage drop calculator
available on the web or CD-ROM.
Approximate wire resistance:
18 AWG solid: 8 ohms/1000 ft.
16 AWG solid: 5 ohms/1000 ft.
14 AWG solid: 3 ohms/1000 ft.
12 AWG solid: 2 ohms/1000 ft.
NOTE: If Class A wiring is installed, the wire length may be
up to twice as long as on non-fault tolerant circuits.
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.
Candela Selection for P, S, PC, & SC series models
For strobe candela selection, adjust the slide switch located
on the rear of the product while watching the viewing window under the reflector on the front of the unit. Use Table
1 to determine current draw at various candela settings.
Table 2 can be used to derate the candela rating for low
temperature operation. Tables 3 & 4 can be used to determine strobe light output at various viewing angles.
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.

NOTE: The 15, 15/75, and 30 cd settings are not intended

Horn Selection for P, PC, & H series models
Horn setting selection is accomplished by using the rotary
switch on the back of the product (see Table 5). The current
draw for various horn settings for horn and 4-wire horn/
strobe products is listed in Table 6. The current draw for
various horn and candela settings for 2-wire horn/strobe
products (P2 series) is shown in Table 7 & 8. The sound
measurements for various horn settings are shown in Table
9 for horn and horn/strobe products.

the horn output will remain constantly on. Positions 7, 8,

2. Connect field wiring according to terminal definitions.
3. If the product is not to be installed at this point, use the
dust cover to prevent contamination of the wiring terminals of the mounting plate.
4. To attach product to mounting plate, hook tabs on the
product housing into the grooves on mounting plate.
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.
5. Secure product by tightening the single mounting screw
in the front of the product housing.

double gang, and 4˝ octagon junction boxes (2-wire
products may be used with a single gang box). If using
a back box skirt, attach the mounting plate to the skirt
and then attach the entire assembly to the junction box
(see Figure 7).

Please refer to insert for the Limitations of Fire Alarm Systems
The Limitations of Horn/Strobes
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 bever
ages. 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.

FCC Statement
SpectrAlert Strobes and Horn/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 generates, uses,

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 in
stalled 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 horn and signal strobe always
be used in combination so that the risks from any of the above limitations are minimized.
