ACCESSORIES

4-WIRE OPTION MODULE

The EB-4 W4-wire option module

plugs into pins on the KB-211, KB-

211GM, and KB-212 speaker stations. It

consists of the necessary circuitry and con-

nectors to convert any of these stations to

4-wire operation, and can accept two 4-

wire connections. This option allows the

speaker station to be used at much longer

distances than are possible with a standard

two-wire intercom line, and also permits

the station to operate via fiber optic cable

and other devices with 4-wire connections.

The module provides a transformer-isolat-

ed audio connection, and does not transfer

the call signal. A station using this option

module must be locally powered.

TW OPTION MODULE

The EB-TW option module plugs into

pins on the KB-211, KB-211GM, and

KB-212 speaker stations. This option

allows the station to send and receive two

channels of audio on a single 3-pin micro-

phone cable. With the TW module in

place, the station can become a part of a

Clear-Com TW system, and is compatible

with TW beltpacks and other components.

V-BOX DESKTOP/WALL-MOUNT

ENCLOSURE

The V-Box converts any of the KB

speaker stations into a desktop, portable, or

wall-mount unit. The station panel may be

secured with four screws in one of the two

mounting spaces, for either an angled or a

vertical panel orientation. A blank plate

with mounting keyholes is provided to

cover the second mounting space. 3-pin

XLR male and female connectors are

mounted on the side panel, wired to a con-

nector block for easy connection to the

speaker station. The rugged metal and

stained-wood enclosure is both durable and

attractive for long-term professional use.
