TOA INTERCOM SYSTEMS
SURFACE-MOUNTED MASTER
STATION AND HANDSET UNIT
HF-670M/HS-670
DESCRIPTION
The TOA HF-670M heavy-duty industrial-use master
station is designed to operate with maximum reliability in
extreme environments, such as high-noise or dust-filled
areas where an ordinary intercom station cannot be used.
It provides hands-free intercom communications, as well
as handset operation when used with the HS-670 handset
unit. The HF-670M station can communicate with all other
master stations in the system. The HF-670M is equipped
with 13 dialing keys, an in-use lamp for eavesdropping
protection, and pre-adjustable microphone sensitivity and
output level volume controls. When it is used with a
separate (PAM-05) booster amplifier and (DS-100) DC
power supply unit, the HF-670M can perform high-level
paging.
*The HF-670M does not have a built-in speaker. A separate speaker such as the
TC-101 A is required.
