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 installa-
tion 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 de-
vices 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. 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 can-
dela 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 ei-
ther 12V or 24V power supplies. The products are not listed for 12V operating
voltages when set to any other candela settings.
