The Electronic School Janitor is 

a schoolbell control unit, ready to 

work, using the SDM-10 device. The 

set is designed for modernization or 

preparing a new bell system. The 

EW-01 includes a switch disconnec-

tor, bellcontroller, relays connected in 

parallel, special purpose buttons for 

switching into the short lessons mode 

and an alarm button with an acoustic 

signalling. The SDM-10 controller is 

the main control part of the system. 

The controller is designed for school 

acoustic signalling control by means 

of bells (e.g.: DNT-212, DNS-212, 

DNT-212M, DNS-212M of ZAMEL).

The system control runs in an auto-

matic mode according to the preset 

algorithm. The program preparing is 

being held by means of entering les-

son and break times, and beginning 

time. The system is ready to imple-

ment some specials functions (alarm 

bells, short lessons) by means of 

programmable control inputs.

NOTE:

The system controls 230 V AC 

bells.It is possible to use 8 and  

24 V AC bells with the TRM-8 or 

TRM-24 doorbell transformers of 

exta series.
