WARNING THIS WIRING ARRANGEMENT IS FOR

PROPERTY DAMAGE AND SERIOUS INJURY OR
DEATH TO YOU AND/OR OTHERS.
APPLICATION NOTES:
CAUTION:
If sheated multiconductor cable or 3/4" conduit fittings are used, check that installed product has sufficient clearance
and wiring room prior to installing backboxes and conduit.
1. For weather resistant installation, use outdoor mounting option. Outdoor backbox must be mounted vertically with “TOP” as
marked to allow any moisture or condensation to drain properly through drain holes on bottom of backbox.
2. The MT4-115-WH can be surface mounted to a standard 4 inch square by 2-1/8 inch deep electrical box (Figure A), weather
resistant backbox (WBB) (Figure B) or a 4 inch square by 1-1/2 inch extension ring and a 4 inch square by 2-1/8 inch deep
electrical box (Figure C).
3. Select largest backbox shown in Mounting Options where possible, to provide additional wiring room for easy installation.
4. Conduit entrance to backboxes should be selected to insure sufficient wiring clearance for installed equipment. When extension
rings are required, conduit should enter through backbox, not extension ring. Use Steel City #53151/1-1/2" deep or #53171/2-1/8"
deep extension rings or equal with same area cut out in back.
5. Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum
stress on the product. This is especially important for stiff, heavy gauge wires with thick insulation or sheathing.
6. Do not pass additional wires (used for other than signaling devices) through the backbox. Such additional wires could result in
insufficient wiring space for the signaling device.
7. The Code-3 Horn and Code-3 Tone incorporate the temporal pattern specified by ANSI/NFPA/ISO for standard emergency
evacuation signaling. They should be used only for fire evacuation signaling and not for any other purpose.
8. The Horn and Bell Tones can be used on coded systems with a minimum On-Time of 1/4 second. All other tones are
recommended for use only on continuous (non-coded) systems.
