School Bell Controller 24-250V AC / 30-300V DC SDM-10/U

The SDM-10 school bell controller is designed to control the acoustic signaling used in schools with school bells. The control is automatic according to the set schedule. The schedule is created by specifying:

• the lesson time
• the duration of the subsequent breaks
• the start time

The device is ready to activate special functions through programmable inputs. The bell controller can be prepared in a version ready for installation as an Electronic Janitor (EW-01). The system design guarantees the backup battery of all settings in the absence of supply voltage.
