NOTE

: 1. Anechoic dBA is measured in anechoic chamber with fast meter response.  2. Reverberant dBA is rated per  UL 464, Standard  for Audible Signal 

Appliances.  3. As per ULC requirement, the -3dB off-axis is 15

°

 and the -6dB off-axis is 30

°

 

WARNING:  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 STROBES. 

 

WARNING:  MAKE SURE THAT THE CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY 

AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM, DSM SYNC MODULES OR WHEELOCK’S 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 current:  use Table 1 to determine the highest value of “Rated Average Current” for an individual horn (across the expected operating voltage 
range of the device); then multiply this value by the total number of devices; be sure to add the current for any other devices powered by the same source and include 
any required safety factors. 

 

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.

1. 

Appliances have in-out wiring terminals that accept two #12 to #18 American Wire Gauge (AWG) wires at each screw terminal.  Strip leads 3/8 inches and 
connect to screw terminals. 

 
2. 

Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision shown in Figure 1.  The polarity shown in the wiring diagrams is for the 
operation of the appliances.  The polarity is reversed by the FACP during supervision.
