Sound Powered Phones

DOE-STD-1031-92

Prior to assigning a portable radio to a work station, it should be tested from all

areas within the work station. This test will ensure that communications can be

established, especially during emergency situations. Because of structural

interference (e.g., concrete walls, large equipment, I-beams), power output of the

radio may be insufficient to communicate. In this situation, consideration may be

given to raising the output power of the radio. If a portable radio cannot be used

from specific areas within a work station, alternate communication equipment must

be supplied.

Since portable radios are a large contributor to control area noise levels and radio

frequency interference, their use must be controlled. A list of all electronic cabinets

that are susceptible to radio frequency interference should be established and

posted with signs prohibiting use. It is advisable not to key portable radios within

approximately 10 feet of posted electronic cabinets.

Facilities may dedicate specific channel frequencies for different organizations. For

example:

Channel 3 (three) for Operations Department personnel and for other

personnel when reporting abnormal operational conditions to the control

area (In this case the control area should continuously monitor channel

three.)

Channel 4 (four) for dedicated support groups, such as maintenance and

facility services

Channel 5 (five) for Security Force personnel.

Sound Powered Phones

Sound powered phones allow communications between two or more specific

stations without the need for external power. Sound powered phones may be used

with party-line or point-to-point communication systems. Since sound-powered

phones require no external power, they can be used during power outages. When

available, this is the preferred communication equipment for routine testing, post-

maintenance testing, or special operational situations that require coordination

through communication.

Personal Pagers

Personal pagers may be provided to operating personnel working in areas where

the facility paging system cannot be heard. Personnel pagers that vibrate and can

be felt may also be used in work areas with high noise levels.
