Application <br />Strobes <br />Genesis G4 Series strobes are UT 1971-listed for use indoors as <br />wall -mounted public -mode notification appliances for the hearing <br />impaired. Prevailing codes require strobes to be used where <br />ambient noise conditions exceed 105 dBA (87 dBA in Canada), <br />where occupants use hearing protection, and in areas of public <br />accommodation as defined in the Americans with Disabilities Act. <br />Synchronization is important in order to avoid triggering seizures <br />in people with photosensitive epilepsy. Al Genesis strobes exceed <br />UT synchronization requirements (within 10 milliseconds over a <br />two-hour period) when used with a synchronization source. See <br />the specifications table for a list of compatible sources. <br />Horns <br />Genesis horn output reaches as high as 92 dBA and features an <br />improved audio frequency range compared with other Genesis <br />horns. This results in excellent sound penetration through walls and <br />a clear warning of danger. Horn only models may be configured for <br />either coded or non -coded notification appliance circuits. They can <br />also be set for high or low dBA output. This setting reduces horn <br />output by about 6 dBA. Horn -only models may be ceiling -mounted <br />or wall -mounted. <br />The suggested sound pressure level for each signaling zone used <br />with alarm signals is at least 15 dBA above the average ambient <br />sound level, or 5 dBA above the maximum sound level having a <br />duration of at least 60 seconds, whichever is greater. These values <br />are measured at five feet (1.5 m) above the floor. The average <br />ambient sound level is A -weighted, fast response sound pressure <br />measured over a 24-hour period. <br />Doubling the distance from the signal to the ear will theoretically <br />result in a 6 dBA reduction of the received sound pressure level. <br />The actual effect depends on the acoustic environment in the space. <br />A 3 dBA difference represents a barely noticeable change in volume. <br />Installation <br />Genesis G4 horns and strobes mount to the required GP10 room <br />side wiring plate. The GP10 mounting plate is ordered separately <br />from the G4 device in packs of 10 for convenient pre -installing and <br />pre -wiring. The device can be removed easily from the room side <br />wiring plate by pushing up with a screwdriver. The cover can also <br />be removed from the device easily with a screwdriver to access <br />the light and sound output settings and a diagnostics test port <br />for voltage testing. <br />Removing Cover Removing Device <br />Genesis LED G4 Series horns, strobes, and horn -strobes mount to <br />any standard one -gang, two -gang, 3.5-inch octagon, and 4-inch <br />square electrical box. Matching optional G4T trim rings are available <br />to cover oversized openings. Optional color matched double -gang <br />surface boxes are also available. <br />Double Gang Electrical Box <br />\ Trim Plate (optional) <br />Two -gang Electrical Box <br />Wiring <br />Horn/strobe + <br />circuit in <br />_ <br />(signal polarity <br />it • <br />shown In the <br />®® ;, <br />active condition) <br />\ <br />\ \ Mounting Plate <br />Machine Screw <br />1' �". <br />mot' Sho n <br />Optional Trim Plate <br />Using a trim plate is optional. <br />One -gang Electrical Box <br />} Horn/strobe <br />- circuit out <br />Shorting Clip <br />Page 2 of 6 <br />DATA SHEET E85001-0668 <br />Not to be used for installation purposes.
