2. The NM100 must be installed by a qualified dealer or installer, and must conform to all local building and electrical codes. 3. For continued protection against risk of fire replace the fuse in the power switch module only with the same type 3 Amp, 250 Volt fuse. 4. Adhere to all warnings on the NM100 and in these instructions. Follow all operating and installation instructions. warning ! These installation instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. • Do not attempt to service the NM100 yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. • Locate the system away from heat sources such as radiators, heat registers, stoves, or other heat producing products. • Do not locate the NM100 master or remote stations in an outside wall. • Do not expose the NM100 to moisture. Doing so can create fire or shock hazards and void the warranty. • Do not place the NM100 master or remote stations in any wall cavity with any other electrical wiring in the cavity. • Install the NM100 system after application of the wall covering material. • Do not expose the outdoor remote station speakers to significant water contact. The outdoor remote speakers are weatherproof but not waterproof. Continuous direct water exposure will cause system problems. • Do not connect a remote or door station wire if you are unsure of its terminating point. Connecting a door station to a remote station may result in system damage. • Do ensure that all rough-in instructions have been followed before power is applied to the NM100 system. • Do not splice cables. Splices are unreliable and defeat the signal isolation properties of the cable. • Do not attach devices unauthorized for use with this system. Authorized devices include: Audio components connected via a line level input NC300 6-disc player • If extra cables have been run for future speaker additions, care must be taken to ensure these cables are not connected to the NM100 master unit. Un-terminated cables (no station) connected to the NM100 master may cause electrical feedback that will damage the master station. • Do not over-tighten the screws for the remote stations or master as the plastic face panels may crack or strip out. • Use only NuTone certified replacement parts and have them installed by a NuTone dealer or installer. Unauthorized substitutions can result in fire, electric shock, or other hazards. • Upon completion of any service or product repair, have the dealer or installer conduct a safety check to ensure the system is in proper operating condition. • Use only a damp cloth to clean the NM100 master and remote stations. Do not use liquid cleaners or aerosol cleaners. Caution: Wiring • A qualified electrician must run a 120V AC line to the NM100 retrofit transformers. • Individual wire runs should not exceed more than 350 FEET of wire from any single remote station to the NM100 master or 1000 total feet for the entire system. • Label all wiring runs. Connecting the wires to the NM100 master, remote station or door stations incorrectly may result in system damage. • Run a single cable from the master unit location to each remote station and door station in a “home run” fashion. Do not loop cable from one remote station to another. • Do not staple cables. Staples cause shorts. • Do not splice cables. Splices are unreliable and defeat the signal isolation properties of the cables. • Do not run electrical wires through the rough-ins. If you encounter 120VAC wires running through a rough-in during a retrofit you must have a qualified electrician rerun those wires around the rough-in. • Keep cables at least 18 inches from fluorescent light fixtures, dimmer controls, and all other wiring. This includes AC wiring, security cable, cordless phone units, and other control wires. These can cause a “hum” or “buzzing” sound. • Keep cables away from objects such as heating and air conditioning ducts, metal construction plates, and anything else with sharp edges that can damage the cables. Caution: Remote Station Rough-In Careful consideration should be used when determining the location of the remote stations and master. Since this is a retrofit system you will not be able to control the location of the existing system. But please follow the guidelines below if you install any ...
