[. . . ] DS12580-001 GAI-TRONICS® CORPORATION A HUBBELL COMPANY Model 12580-001 Amplifier Distribution/Monitor Module General Information This data sheet applies to the GAI-Tronics Model 12580-001 Amplifier Distribution/Monitor Module (ADM). It is used to distribute audio to up to six central amplifiers, verify the integrity of the related speaker loops, and to monitor up to six amplifier failure contacts reporting their status to the MCU. [. . . ] The CPU PCBA monitors the status of the module's contact closure inputs and speaker loop inputs and reports them to the MCU via this communication link. The MCU identifies a particular module on this RS-485 link by its address. GAI-Tronics Corporation 400 E. Mohnton, PA 19540 USA 610-777-1374 800-492-1212 Fax: 610-796-5954 VISIT WWW. GAI-TRONICS.
