WIRING & INSTALLATION:

JUMPERS:

In multi-master system, remove E/- jumper at master and sub stations. When add-on selector is included, remove X2/X3 jumper.

INTERNAL CONTROLS:

CALL TONE VOL.: SW4, located inside unit under select switch panel, controls call tone volume. Level is set at max. from factory. Change position to lower call tone volume. VOX. SENSITIVITY: Potentiometer is located inside unit behind handset. Adjust for sensitivity of VOX circuit. SW5 SWITCH: In "A" position from factory, which mutes call tone from sub while system is occupied. "B" position allows call tone to be heard while system is occupied.

TRANSMIT RECEIVE

Before Installation:

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

· All Call and/or background music are optional features which require 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. See diagram on page 3.

Wire:

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

· Wiring between masters must be a multi-conductor cable. If more than one cable is used to connect masters, the "E", "C", and number terminal wires must be in the same jacketed cable. If necessary, run multiple "E" wires, one in each cable.

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 nearest master station, or daisy-chained. If daisy-chained, include 2 common wires plus one individual wire per station on the run.

· In a SINGLE MASTER SYSTEM ONLY: Subs can be wired with 2 conductors homerun. Jumpers between "E" and "-" must be attached on all subs and at the 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.

All Call and Background Music:

· The BG-10C adaptor and PS-1225UL power supply are required for each group of 11 stations to receive All Call and music. This equipment should be installed in an equipment room or in a cabinet. Capacitors (NP-25V) are required for each sub station on the system. See wiring diagram on page 5 for installation information.

NOTES: Two wiring method can be used:

1. 2 conductor homerun to each sub station from the master. (Single master system only.)

2. Run multi-conductor wire in a daisy-chained fashion with 2 common wires (E & -) plus one individual wire per station on the run. Remove jumpers between E & - when daisy-chained method is used.

3. To protect system from power surge, install SA-1 arrestors at master station. One SA-1 is required for every two wires connected to master.
