GENERAL DESCRIPTION

The SpectrAlert Advance amber lens strobe products offer an amber colored
strobe with the word “ALERT” printed on the white housing to comply with
the latest standard for mass notification systems. They are designed to be used
in 12 or 24 volt, DC or FWR (full wave rectified) systems. Amber lens strobes
are UL Listed under 1638 (Visual Signaling Appliances) for Private Mode Gen­eral Utility Signaling. Device may be mounted to either wall or ceiling. All
SpectrAlert Advance products are suitable for use in synchronized systems.
The System Sensor MDL module may be used to provide synchronization. The
speaker portion can be operated with distribution amplifiers having an output
voltage of either 25 or 70.7 volts. With its low total harmonic distortion, the
SpectrAlert Advance SP series offers high fidelity sound output. The speakers
operate at any one of four input power levels. These products are electrically
backward compatible with the previous generation of SpectrAlert notification
appliances.

FIRE ALARM SYSTEM CONSIDERATIONS

All wiring must be installed in compliance with the National Electrical Code
(NEC) and applicable local codes. System Sensor recommends installing fire
alarm speakers in compliance with NFPA 72, ANSI/UL1480 and NEC 760.

/4, 1/2, 1, 2 watts

LOOP DESIGN AND WIRING

The system designer must make sure that the total current drawn by the de­vices on the loop does not exceed the current capability of the panel supply,
and that the last device on the circuit is operated within its rated voltage.
The current draw information for making these calculations can be found in
the tables within this manual. For convenience and accuracy, use the voltage
drop calculator on the System Sensor website (www.systemsensor.com) or
CD-ROM.

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. Wire resistance tables can be obtained
from electrical handbooks. Note that if Class A wiring is installed, the wire
length may be up to twice as long as it would be for circuits that are not fault
tolerant.

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.

NOTE: Supply power for strobe must be continuous for proper operation.

ELECTRICAL WIRING

1. Connect the speaker as shown in Figure 1.

NOTE: Do not loop electrical wiring under terminal screws. Wires con-

necting the device to the control panel must be broken at the device
terminal connection in order to maintain electrical supervision.

2. There are two rotary switches on the back of the product The first switch
is used to select either 25 or 70.7 volts input for the speaker portion. The
second switch is used to select the input power of 1/4, 1/2, 1 or 2 watts.
See diagram.

SHORTING SPRING

NOTE: Shorting springs are provided between terminals 2 and 3 and between
terminals 5 and 6 of the mounting plate to enable wiring checks after the
system has been wired, but prior to installation of the final product. These
springs will automatically disengage when the product is installed, to enable
supervision of the final system.

Signal levels exceeding 130% rated signal voltage can damage the speaker.
Consequently, an incorrect tap connection may cause speaker damage. This
means that if a 25V tap is selected when a 70.7V amplifier is being used,
speaker damage may result. Therefore, be sure to select the proper taps for the
amplifier voltage/input power level combination being used.

CANDELA SELECTION

Adjust the slide switch on the rear of the product to position the desired can­dela setting in the small window on the front of the unit. For amber lensed
strobes used for full profile measurement, listed candela ratings must be re­duced in accordance with Table 3. Use Table 2 to determine the current draw
for each candela setting.

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.

MOUNTING

1. Attach mounting plate to junction box as shown in Figure 4. The mounting
plate is compatible 4˝ x 4˝ x 21/8˝ junction boxes. If using a back box skirt or
trim ring, attach the mounting plate to the skirt or trim ring and then attach
the entire assembly to the junction box (see Figures 4 and 5).

2. Connect field wiring to terminals, as shown in Figure 1.

3. If the product is not to be installed at this point, use the paint cover to
prevent contamination of the mounting plate.

4. To attach product to mounting plate, remove the paint cover, then hook

5. 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.

6. Secure product by tightening the single mounting screw in the front
of the product housing. For tamper resistance, the standard captivated
mounting screw may be replaced with the enclosed Torx screw.

WARNING

Please refer to insert for the Limitations of Fire Alarm Systems

THE LIMITATIONS OF SPEAKER/STROBES

The speaker and/or strobe will not work without power. The speaker/strobe gets
its power from the fire/security panel monitoring the alarm system. If power is cut off
for any reason, the speaker/strobe will not provide the desired audio or visual warning.
Always make sure that the individual speakers are tested after installation per NFPA
regulations.
The speaker may not be heard. The loudness of the speaker meets (or exceeds) the
current Underwriters Laboratories’ standards. However, the speaker may not attract the
attention of a sound sleeper or one who has recently used drugs or has been drinking
alcoholic beverages. The speaker 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. Traffic,
air conditioners, machinery, or music appliances may prevent even alert persons from
hearing the alarm. The speaker may not be heard by persons who are hearing impaired.

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