NuTone Nm100WH Connecting the Antenna, Door Release Options, Door or Gate Release Mechanism

model NM100WH

Connect the optional NC300 player RCA cables and control wire. See additional instructions packed with the NC300 CD changer.

Connecting the Antenna

Separate the intercom cables from the antenna leads, if grouped together the intercom cables can shield the antenna leads resulting in poor radio reception. Keep the antenna leads away from metal ductwork and aluminum backed insulation. These can also shield the antenna leads.

The number and style of antenna leads will vary based on the intercom system being replaced. The NM100 system is designed to use the existing antenna. See next figure.

Follow the steps below to attach a NuTone 300 Ohm twin lead antenna to the NM100.

If the antenna has a plug on the end, cut the plug off

1.Strip the 2 wire ends

2.Connect the wire ends to terminal S1 and S2 on the antenna board

3.Connect a bare jumper wire (a 22 gauge speaker wire works well) between the S3 and S4 terminals.

Follow the steps below to attach a separate AM/FM antenna system with 300 Ohm FM twin lead and orange AM antenna wire:

1.Connect the FM twin leads to terminal S1 and S2 on the board

2.Connect the AM antenna (orange wire) to terminal S4

3.Terminal S3 is not used in this configuration

Follow the steps below to connect a single orange wire antenna system:

1.Connect the orange wire to either S1 or S2. Note do not connect the wire to both S1 and S2 doing this will short out the FM antenna signal.

2.Connect a bare jumper wire (a 22 gauge speaker wire works well) between the S3 and S4 terminals.

Door Release Options

The door release option is a dry contact closure provided by the NM100 master. This dry contact is rated 24 Volt/2 Amps. The sample applications below represent some uses of this option. However, only one application can be used in any NM100 system at a time.

Door or Gate Release Mechanism

Run a single line of 18 gauge solid copper, twisted pair approved low voltage cable from the NWH300 or NWH300C rough-in to the door release mechanism. Connect the two wires from the 18 gauge solid copper cable to the two wire terminals of the door release mechanism.

Run another single line of 18 gauge solid copper, twisted pair approved low voltage cable from the NWH300 or NWH300C rough- in location to a gang box next to a 120VAC receptacle where the remote door/gate release power transformer will be plugged in. Label and secure cables at the rough-in.
