Manual

Installation

1. The intercom requires one pair of wires for each elevator

from the lobby panel to the elevator unit. The intercom

system requires 110 volts to trickle charge the battery.

The wiring from the AC wall plug can be extended as

needed to get to the nearest outlet or to go to the

Machine Room. Connectors are provided.

2. Install the elevator unit on the ceiling using the mounting

holes provided in the galvanized box. The elevator unit

can be mounted behind a speaker grill in the car return.

(3.5-inch minimum speaker pattern required). The

galvanized box will need to be removed from the elevator

intercom.

3. Install the lobby unit using the bracket if needed.

4. Connect the AC power to the Lobby unit.

5. On Simplex installations, connect one pair of wires

between the TELCO connector of the Lobby unit and the

TELCO connector of the elevator unit. This connection is

polarity sensitive so be sure to connect No. 1 connections

together and No. 2 connections together.

Note: On Duplex, Triplex, Quadruplex, there will be a

European connector at the Lobby panel with a pair of

connections for each elevator. When you connect the wiring

at the TELCO connector on the elevator unit, be sure that

the positive voltage is connected to the No. 2 side of the

connector. Positive and negative are marked on the board.
