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 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.

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.

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 Horn Selection for P, PC, & H 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.
