General Description
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.
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 compat-
ible 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) sys-
tems. If required, the MDL module may be used in order to
provide synchronization.
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.
NOTICE: This manual shall be left with the owner/user of
this equipment.
Fire Alarm System Considerations
Approximate wire resistance:
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.
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.
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.
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.

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 hous-
ing fully engage with the mounting plate.

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).

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.
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

include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to replace units which are found to be
defective because of damage, unreasonable use, modifications, or alterations
occurring after the date of manufacture. In no case shall the Company be
liable 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

limitation or exclusion may not apply to you. This Warranty gives you specific
legal rights, and you may also have other rights which vary from state to state.
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,
and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference
in which case the user will be required to correct the interference at his own expense.
