1 100 91 81
2 83 88 78
3 67 85 75
Power Input Voltage: 20-31VDC
Appliance Input Level: 500mV RMS
Appliance Input Impedance: 600 Ohms
Sound pressure level and current measurements were made with 500mV sinewave appliance.
Anechoic dBA is measured on axis in a non-reflective (free field) test room using fast meter response. Reverberant dBA is a
minimum UL rating based on sound measurements in a reverberant test room.

NOTE: THE MAXIMUM WIRE IMPEDANCE BETWEEN STROBES SHALL NOT EXCEED 35 OHMS. THE MAXIMUM NUMBER
OF STROBES ON A SINGLE NOTIFICATION APPLIANCE CIRCUIT SHALL NOT EXCEED 31.
WARNING: MAKE SURE THAT THE TOTAL CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO
THE SYSTEM'S PRIMARY AND SECONDARY POWER SOURCES AND SIGNALING CIRCUITS, SM AND DSM SYNC MODULES
DOES NOT EXCEED THEIR RATED CURRENT. OVERLOADING THESE SOURCES 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 current: use Table 2 to determine the highest value of "Rated Average Current" for an individual strobe
(across the expected operating voltage range of the strobe); then multiply this value by the total number of strobes; be sure to add the
current for any other appliances, including audible signaling appliances, powered by the same source and include any required safety
factors. Use Table 1 to calculate the total audible appliance current in the same manner.
WARNING: MAKE SURE THAT ALL FUSES USED ON SIGNALING CIRCUITS ARE RATED TO HANDLE THE MAXIMUM
INRUSH OR PEAK CURRENT FROM ALL APPLIANCES ON THOSE CIRCUITS. FAILURE TO DO THIS MAY RESULT IN LOSS
OF POWER TO THE SIGNALING CIRCUIT AND THE FAILURE OF ALL APPLIANCES ON THAT CIRCUIT TO OPERATE,
WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
When calculating the maximum inrush or peak current: use Table 2 to determine the highest value of "Rated Inrush Current" or
"Rated Peak Current" (whichever is higher) for an individual strobe (across the expected operating voltage range of the strobe); then
multiply that value by the total number of strobes on the circuit; be sure to add the inrush or peak currents from any other appliances
on that circuit and include any required safety factors. The time duration of the maximum strobe inrush or peak current is 2
milliseconds for LS/LSM/MS/SL/SLM models and 4 milliseconds for IS models. Calculate the maximum inrush current for all
audible appliances in the same manner. The audible appliances produce a brief inrush current that lasts for just 2 microseconds but
can reach a peak value of 8.0 Amps.
CAUTION
: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
