2. Anechoic dBA is measured on axis in a non-reflective (free field) test room using fast meter response. For peak dBA (measured
with peak meter response), add 5dBA to anechoic values as shown in Table 2. Reverberant dBA is a minimum UL rating based on
sound pressure measurements in a reverberant test room.

3. All models are UL Listed for indoor use with a temperature range of +32oF to +120oF (0oC to +49oC) and maximum humidity of
85% RH.
Check the minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the circuit
wiring resistance to determine the applied voltage to the signaling appliance.

WARNING: ALTHOUGH UL TESTING HAS VERIFIED THAT THESE PRODUCTS FUNCTION EVEN AT 80% OF
THEIR MINIMUM RATING AND 110% OF THEIR MAXIMUM RATING, DMP STRONGLY RECOMMENDS THAT
THE VOLTAGE APPLIED TO THESE PRODUCTS BE WITHIN THEIR RATED VOLTAGE RANGE. THE
APPLICATION OF IMPROPER VOLTAGE MAY RESULT IN DEGRADED OPERATION OR DAMAGE TO THESE
PRODUCTS, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.

* 15cd models are UL Listed at 15 candela and meet 75cd on axis. ** The time duration for the peak current is 100 microseconds.
*** The time duration for the inrush current is 4 milliseconds.
WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT, TOTAL PEAK CURRENT AND TOTAL
INRUSH CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY
AND SECONDARY POWER SOURCES, SIGNALING CIRCUITS, SYNC MODULE AND DUAL SYNC MODULE 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 average, peak and inrush currents: Use Table 3 to determine the highest value of “Rated Average Current”
for an individual strobe (across the expected operating voltage range of the strobe), and use Table 3 to determine the highest value of
“Rated Inrush Current” or “Rated Peak Current” (whichever is higher) of an individual strobe (across the expected 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 inrush current or peak current exceeds the power supplies’ inrush 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: Audible Horn Strobe are not designed to be used on coded systems in which the applied voltage is cycled on and off.
