instructions INCORRECT SETTINGS WILL RESULT IN IMPROPER PERFORMANCE F 2 of 5 Always operate audio amplifiers and speakers within their specified ratings Excessive input may distort sound and may damage audio equipment Improper input voltage can damage speaker If distortion is heard check for clipping of audio appliance with an oscilloscope and reduce the amplifier input level or gain level to eliminate any clipping OPTIONS The following figures show the maximum number of field wires conductors that can enter the backbox used with mounting option If these limits are exceeded there may be insufficient space in the backbox to accommodate the field wires stresses from the wires could damage the product the limits shown for each mounting option comply with the National Electrical Code NEC Cooper Wheelock use of the largest backbox option shown and the use of approved stranded field wires whenever possible to provide wiring room for easy installation and minimum stress on the product from wiring FLUSH MOUNTING NON STROBE SPEAKER BOX 8 32X1 2 PLATE MAXIMUM NUMBER OF CONDUCTORS 18 AWG 16 AWG 14 AWG 12 4 4 4 4 Surface backbox E50SB in Figure B is compatible with wiremold and conduit Mounting holes are for single gang and 10 wood screws for stud mounting If metal conduit is installed onto top and bottom conduit entrances then an grounding wire 18 AWG supplied must be connected between the top and bottom plate by using thread cutting screws to provide electrical continuity per UL 50 See Figure 5 Figure 5 F 3 of 5 PROCEDURES Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and especially if sheathed multiconductor cable or 3 4 conduit fittings are used E50 models have an integrated Speaker Mounting Plate The Speaker Mounting Plate must be oriented correctly when it is mounted to the backbox Refer to mounting options for mount the Speaker Mounting Plate to the backbox Next slide the grille over the Speaker Mounting Plate until both snaps engaged When terminating field wires do not use more lead length than required Excess lead length could result in insufficient wiring for the signaling appliance Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product Do not pass additional wires used for other than the signaling appliance through the backbox Such additional wires could in insufficient wiring space for the signaling appliance Mounting hardware for each mounting option is supplied Use 2 wood screws to mount surface backbox on wall surface All models can be flush mounted to a 4 square by 2 1 8 deep backbox in the wall Figure A Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum on the product This is especially important for stiff heavy gauge wires and wires with thick insulation or sheathing Use care to prevent speaker cone damage when driving screws for speaker product mounting this appliance is required to produce a distinctive three pulse Temporal Pattern Fire Alarm Evacuation Signal for total evacuation accordance with NFPA 72 the appliance must be used with a fire alarm control unit that can generate the temporal pattern signal to manufacturer installation manual for details NFPA 72 ANSI 117.1 conforms to ADAAG Equivalent
