Raytheon Service Co. Brochure Describes A u t o - A l a rm RCVR/KYR

Raytheon Service Company recently published a brochure describing their new Auto-Alarm Receiver / Keyer. The Raytheon Auto-Alarm, Model RAY-1AAR/ K is a solid-state rackmountable unit designed to monitor the 500- kHz international radiotelegraph distress frequency band and actuate a continuous audible alarm upon detection of a distress signal.

The RAY-1AAR/K contains several unique design features, including automatic gain control (AGC) system for optimum receiver sensitivity, precise recognition of valid distress signals, and type approval in conformance with FCC 1981 timing regulations, Part 83.554.

The signal keyer automatically "keys" radiotelegraph transmitters with the International Radiotelegraph Alarm signal. The 12-volt d-c power source required to operate the Signal Keyer is normally supplied by the radioroom emergency battery supply.

The Auto-Alarm is presently installed in Solas Communication Consoles onboard a number of ships.

For complete details and a free copy of the four-page brochure on the A u t o - A l a rm Receiver/ Keyer, write Charles Chartier, MR-1, Raytheon Service Company, 2 Wayside Road, Burlington, Mass. 01803.
