Description of the school bell controller.
Technical specifications:
Application: The SDM-10 school bell controller is designed to control the acoustic signaling used in schools with school bells (e.g., DNT-212, DNS-212, DNT-212M, DNS-212M). The control is automatic according to the set schedule. The program is created by specifying the lesson time, the duration of the subsequent breaks, and the start time. The device is ready to activate special functions (alarm bells, shortened lessons) via programmable inputs.
The bell controller can be prepared in an installation-ready version as Electronic Janitor (EW-01). The design of the system ensures the backup battery of all settings in the absence of power supply voltage.
