MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE TO THE SYSTEM PRIMARY AND SECONDARY POWER SOURCES DO NOT EXCEED THE POWER RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE ARE WIRED OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY WHICH COULD RESULT IN DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND OR OTHERS calculating the total currents Use Table 1 to determine the highest value of Current for an individual horn across expected operating voltage range of the horn then multiply these values by the total number of horns be sure to add the for any other appliances including audible signaling appliances powered by the same source and include any required

4 conduit fittings are used check that installed product has sufficient and wiring room prior to installing backboxes and conduit weather resistant installation use outdoor mounting option see Mounting Option B Outdoor backbox must be vertically with TOP as marked to allow any moisture or condensation to drain properly through drain holes on of backbox Operate only within specified voltage range for rated performance and endurance All horns will operate on coded systems up to 3 on off cycles per second Anechoic dB ratings are for free field anechoic conditions Such conditions are approximated in outdoor installations installations provide greater dB because of reflected sound energy terminals with wire clamps 2 leads 12 22 American Wire Guage AWG wire per position are allowed Strip approximately 3 8 for connection to terminals Break wire run to provide electrical supervision largest backbox shown in Mounting Options where possible to provide additional wiring room for easy installation Conduit entrance to backboxes should be selected to insure sufficient wiring clearance for installed equipment When rings are required conduit should enter through backbox not extension ring Use Steel City 53151 1 1 2 deep 53171 2 1 8 deep extension rings or equal with same area cut out in back Backboxes for all horns should be securely mounted Looseness may degrade sound output If these appliances are operated within 15 inches of a person ear they can produce a sound pressure level that the maximum 120dBA permitted by ADA and OSHA rules Exposure to such sound levels can result in damage to a hearing Check the installation instructions of the manufacturers of other equipment used in the system for any or restrictions on wiring and or locating Notification Appliance Circuits
