To control the school bell, a microprocessor was used, which guarantees that the length of all lessons and breaks between them will be in line with the expectations of teachers and students. The system uses a battery backup time and non-volatile memory, so that no accidental power supply failure will cause the need to re-programming the switch-on times.
The controller works in one-day mode. It allows programming the length and number of lessons, length of breaks and the duration of the bell operation. After specifying the start time of the first lesson, all other parameters (for the daily timetable) are automatically calculated.
The system is easy to assemble, reliable in operation and seems indispensable in every school.

The device is especially recommended for lovers of punctually beginning and ending lessons, teachers and all students

Selected parameters of the controller:

• work in 24-hour mode
• setting the lesson / break time in 5 min steps
• setting any number of lessons
• Possibility to program breaks of different duration
• displaying the current time
• presentation of the operating mode - 2x16 alphanumeric LCD display
• executive system - relay
• battery backup operation in the event of network failure
• power supply - 230 V
• a programmed layout in the set
