ELECTRONIC SCHOOL JANITOR EW-01
DESCRIPTION
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.
