Measuring Instruments & Devices

On a typical day in the school a students school activity starts with the first bell followed by a series of bell ringing to notify the beginning and the end of various activities including teaching periods.

For this purpose generally the ringing of the bell is done manually. This results many a time in human error in ringing the bell at the right time.Instead a microprocessor based electronic instrument can be programmed to activate and ring the bell at preset time for the entire day.

The instrument can also be programmed to cater to different zones in the school. Such an instrument is totally independent of any human intervention and works automatically once programmed.

Electronic Bell is such an instrument designed and developed to cater to the needs of a big school having different zones (wings) with different time table for each day. The program for the whole week can be stored in the instrument.It is a portable instrument with the facility to connect bells in the three different zones.

The instrument has provision to ring the bells up to a maximum of twenty times in a day following a predetermined program.All the parameters like the duration for which the bell rings at a time, the time duration between ringing of two bells etc are user settable and password protected.In the case of an emergency or if desired there is provision to ring the bell manually overriding the preset program.
