GENERAL DESCRIPTION
The SpectrAlert Advance Dual Strobe and Dual Strobe with Speaker Expander
Plates for emergency communications uses a single device plate to perform the
functions of two to three devices on a back box. This combination of multiple
devices on a single plate and back box lowers the overall cost of the installation and improves aesthetics by requiring fewer devices on the wall.
The expander plate provides fast and easy installation – first, mount the plate
to a junction box and connect the field wiring to the terminals. Then, hinge
and attach the strobe or speaker strobe device with a captured mounting screw
to complete the installation. This product is comparable to existing SpectrAlert
Advance mounting plate installations.
Dual Strobe and Dual Strobe with Speaker Expander Plates are designed to
be used in 12 or 24 volt, DC or FWR (full wave rectified) systems. Amber
lens strobes are UL1638 Listed (Visual Signaling Appliances) for Private Mode
General Utility Signaling. All SpectrAlert Advance products are suitable for use
in synchronized systems. The System Sensor MDL3 module may be used to
provide synchronization.
The Dual Strobe and Dual Strobe with Speaker Expander Plates are
designed for use on wall and ceiling applications.
NOTE: For ceiling mount applications the amber lens strobe meets UL 1638
light requirements, however the device will not meet all of UL1971 polar plot
light requirements.
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 CDROM. See Figures 1-4 for wiring diagrams and shorting spring information.
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.
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. All products meet
the light output profiles specified in the appropriate UL Standards. For amber
lensed strobes used for full profile measurement, listed candela ratings must
be reduced in accordance with Table 2. Use Table 1 to determine the current
draw for each candela setting.
NOTE: SpectrAlert Advance products set at 15 and 15/75 candela 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 total number of strobes on a single NAC must not exceed 40 for
24 volt applications or 12 for 12 volt applications. Loop resistance on a single
NAC should not exceed 120 ohms for 24 volt and 30 ohms for 12 volt systems.

MOUNTING THE SEP-SPSW SPEAKER STROBE EXPANDER PLATE
1. Attach the speaker strobe expander plate to the junction box as shown in
Figure 5. The speaker strobe expander plate is compatible with a 4˝ x 4˝
x 21/8˝ junction box. If using a back box skirt, attach the speaker strobe
expander plate to the back box skirt and then attach the entire assembly
to the junction box (see figure 6).
2. Connect the field wiring to the terminals, as shown in Figure 1.
3. If the speaker strobe device is not to be installed at this point, use the
paint cover to prevent contamination of the speaker strobe expander
plate.
4. To attach the speaker strobe device to the speaker strobe expander plate,
remove the paint cover, then hook the tabs on the product housing into
the grooves on the strobe plate.
5. Swing the speaker strobe device into position to engage the pins on the
device with the terminals on the speaker strobe expander plate. Make
sure that the tabs on the back of the device housing fully engage with the
expander plate.
6. Secure the speaker strobe device by tightening the single mounting
screw in the front of the speaker strobe housing. For tamper resistance,
the standard captive mounting screw may be replaced with the enclosed
Torx screw.

wiring terminals.
4. To attach strobe device to the strobe expander plate, remove the paint
cover, then hook tabs on the product housing into the grooves on strobe
expander plate.
5. Swing the strobe device into position to engage the pins on the device
with the terminals on the strobe expander plate. Make sure that the tabs
on the back of the product housing fully engage with the strobe expander
plate.
6. Secure the device by tightening the single mounting screw in the front of
the device housing. For tamper resistance, the standard captive mounting
screw may be replaced with the enclosed Torx screw.

WARNING
THE LIMITATIONS OF STROBE AND SPEAKER STROBE EXPANDER PLATE
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 beverages. 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.
THREE-YEAR LIMITED WARRANTY
System Sensor warrants its enclosed product to be free from defects in materials and
workmanship under normal use and service for a period of three years from date of
manufacture. System Sensor makes no other express warranty for this product. No agent,
representative, dealer, or employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s obligation of this Warranty
shall be limited to the replacement of any part of the product which is found to be defective in materials or workmanship under normal use and service during the three year
period commencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization number, send defective units postage prepaid to: System Sensor, Returns Department, RA #__________, 3825
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

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