Installation

WARNING

Always remove power to this station and any associated equipment before

beginning any installation.

Install equipment without modification and according to all applicable local and national electrical codes.

Consult the National Electrical Code (NFPA 70), Canadian Standards Association (CSA 22.1), and local

codes for specific requirements regarding your installation. Class 2 circuit wiring must be performed in

accordance with NEC 725.55.

CAUTION

The factory-sealed section of this station is only to be opened for maintenance or repair by factory

authorized personnel. Refer to the "Maintenance" section for more details.

WARNING

After installing station and before applying power, verify that the bolts on the factory-sealed section

of the station are set at 30 ft-lbs.

This station has a highly sensitive microphone that allows the user to communicate at a distance from the

station. This station also contains a high gain amplifier that enables operation in high noise

environments.

To prevent feedback problems in the system, the ambient noise levels, volume settings, and station

placement must be taken into consideration. In most cases, stations can be mounted perpendicular to the

same surface and be placed 150 feet apart. This minimum spacing requirement between stations can be

reduced under the following conditions:

•

the stations are installed in a high noise environment;

•

they are configured for simplex mode (depressing T button);

•

they contain speaker L-pads;

•

they are placed in separate rooms.
