2 COMPONENTS & WIRING (Cont.)

WIRING & INSTALLATION:

Before Installation:

·Make sure you have the proper power supply(ies) and all necessary and compatible equipment for the system.

·Background music is optional and requires additional equipment. See notes below.

·Lay out your system in advance, assigning station numbers for all sub station locations.

·Surge protection for the intercom equipment is strongly recommended. Add SA-1 surge arrestors for the power supply, plus one per two wires connected to the master station.

Wire:

· Shielded wire is strongly recommended. Use the proper gauge for the distance being run.

Wiring Method:

·Run intercom cables at least 20" away from all AC wiring, fluorescent lights, dimmer switches, and other electrical or electronic devices. Wiring can cross AC wires at 90 degrees.

·Sub stations may be homerun to the master station, or daisy-chained. If daisy-chained, include one common wires plus one individual wire per station on the run.

·If more than one master is used, homerun sub to the NEW-5 Dual Master Adaptors, then wire NEW-5's to each master.

Intercom Locations:

·Do not install intercoms near dimmer or light switches, or other electrical wall devices.

·To prevent feedback, do not place sub stations back-to-back on a common wall.

Mounting the Master & Add-On Units:

·Each master and add-on requires three rack console spaces.

·Secure the masters and add-on stations using the included screws. See information provided with your rack console for more detailed information.

Mounting the terminal board:

·Make sure that the appropriate terminal board assembly is used for the master and add-on selector(s). Master and add-on mother terminal boards mounted on terminal board assembly are different and are NOT interchangeable.

·Secure the terminal board inside the rack console using the supplied screws

·Terminal board must be mounted within 5' of the master and add-on units, connected with ribbon cables.
