Product Details:
The SR-700 Remote Control System is designed to control a transciever from a remote location of up to three miles with only 2 wires. The system also has an intercom capability allowing an operator at either location to ring a bell or light a lamp at the other location and talk with the operator at that location.

The SR-700 Remote Control System consists of two units. The local unit (SR-700L) is located at the transciever location. The remote unit (SR-700R) can be located anywhere within 3 miles of the transciever. Both units contain a magneto generator for signalling the other unit and a light and a bell for receiving the signal. Batteries (1 D cell per unit, not included) are contained in each unit to power the handsets for intercom use if external power (12 vdc) fails.

The local unit contains an audio amplifier for increasing the audio signal from the transciever to a nominal 0dBm at the remote location. The local unit also contains a constant current power supply to power the local and remote handsets. The keying relay and its drive circuit, which are located in the local unit, senses a handset closure in either the local or remote unit and keys the transciever.

In addition to the circuits used for intercom and remote voice operation of the transciever, the remote unit has provisions for the sending and receiving of TTY signals. Both the local and remote units are housed in splashproof metal cases. Handsets and manual included.
