Add strobe current from Table 3 to audible appliance current from Table 2 to obtain total current for each unit, if the strobe and audible are wired to
operate in unison on a single circuit.
WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO
THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM, DSM SYNC MODULES OR WHEELOCKS
POWER SUPPLIES DO NOT EXCEED THE POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES
ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED. OVERLOADING POWER SOURCES OR EXCEEDING FUSE
RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY, WHICH
COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
When calculating the total currents: Use Table 3 to determine the highest value of “RMS Current” for an individual strobe (across the expected
operating voltage range of the strobe), then multiply these values by the total number of strobes; be sure to add the currents for any other appliances,
including audible signaling appliances, powered by the same source and include any required safety factors.
If the peak current exceeds the power supplies’ peak capacity, the output voltage provided by the power supplies may drop below the listed voltage
range of the appliances connected to the supply and the voltage may not recover in some types of power supplies. For example, an auxiliary power
supply that lacks filtering at its output stage (either via lack of capacitance and/or lack of battery backup across the output) may exhibit this
characteristic.
CAUTION:
Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
MT MULTITONE SETTINGS:
The Switch (SW1) of the Multitone Appliance, shown in Figure 1, is used to set the dBA sound output level and alarm tone. The factory settings are
shown below.
Read these instructions carefully before changing any of these factory settings
.

USE A SMALL SCREWDRIVER TO
CHANGE THE SWITCH POSITION.
STEP 1:
Set desired dBA sound output level as follows (Refer to Figure 1 and Table 4):
Multitone Strobe Appliances cannot be field set for input voltage. Multitone Strobe Appliances are field set for dBA sound output level by adjusting a
four position Switch (SW1) as shown in Table 4 and Figure 1. Use SW1 Position 1 to select the dBA sound output level.
