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 Gen-
eral 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 MDL3 module may be used to provide synchronization.
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.
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. For amber lensed
strobes used for full profile measurement, listed candela ratings must be re-
duced in accordance with Table 2. Use Table 1 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 op-
erating voltages when set to any other candela settings.
MOUNTINg
1. Attach mounting plate to junction box as shown in Figures 3 and 4. The
mounting plate is compatible with 4” square, double gang, and 4” octa-
gon junction boxes. If using a back box skirt, attach the mounting plate
to the skirt and then attach the entire assembly to the junction box (see
Figures 3 and 4).
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
tabs on the product housing into the grooves on mounting plate.
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.

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 maxi-
mum loop resistance of 30 ohms.Figure 2. Shorting Spring:
