Alpha A-4800M Master Annunciator with Handset

The A-4800M from Alpha is a digital Emergency Communication System designed to provide fully supervised, two-way voice communication between each 4800V area of refuge call station and the Main Control Panel. An internal modem, operating at the Main Control Panel, connected to a dedicated telephone line, provides an automated-timed dial-out capability to a monitoring location. The system continuously polls all the 4800V Call Stations, area of rescue control panels, and Expansion Switches to identify line faults and defective equipment, ensuring reliability and safety in emergency situations. Activated Call Station locations and fault information are displayed on the 40 character LCD four line display at each Control Panel location. Each remote call station is also equipped with auxiliary momentary Form ‘C’ contacts for activating external devices like cameras or alarms.
