General Description
The SpectrAlert series notification appliances are designed to meet the
requirements of most agencies governing these devices, including: NFPA,
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.
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 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 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.
Specifications
Voltage Range: DC or Full-Wave Rectified
Chime: 8–33 Volts
Operating Temperature: 32˚F to 120˚F (0˚C to 49˚C)
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 464; Private Mode
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.

SpectrAlert Electronic Chime Sound Output Guide
Chime Selection
Chimes are factory set for high volume, 1000Hz, 1 second chime. Tones
may be selected by making the appropriate settings on the Dip Switch
located on the printed circuit board. The settings required for the available
tone options are as follows:
SpectrAlert Chime Switch Settings
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.
SpectrAlert Electronic Chime Current Draw*
12VDC: 18–31mA
24VDC: 31–61mA
*Average current draw varies with tones selected. Current ratings per

Mounting
1. The chime is intended for mounting to a standard 21/2″deep single-
gang box which allows sufficient clearance for conduit entrance.
2. The chime is compatible with DC line supervision, is polarized, and
has terminals marked with polarity. Apply positive supply voltage to
the (+) terminal and negative supply voltage to the (–) terminal. (See
Figure 1.)
3. Mount the chime to the electrical outlet box using the two mounting
screws supplied.
4. Field repair of the chime should not be attempted. Return to factory
for repair or replacement.
*NOTE: Shown with control panel in alarm. Panel polarity reversed in
supervisory condition.

The chime will not work without power. The chime gets its power from
the fire/security panel monitoring the alarm system. If power is cut off
for any reason, the chime will not provide the desired audio or visual
warning.
The chime may not be heard. The loudness of the chime meets (or
exceeds) current Underwriters Laboratories’ standards. However, the

chime may not alert a sound sleeper or one who has recently used drugs
or has been drinking alcoholic beverages. The chime may not be heard if
it is placed on a different floor from the person in hazard or if placed too
