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.

MOUNTING
CONNECTIONS
1. The device connected to the other bells in parallel.
2. The device connected to the existing bell system.
1. Disconnect the electric network by
means of an appropriate cut-off,
current-limiting circuit-breaker or
separator.
2. Check if there is no any voltage-
between power leads by means
of an appropriate gauge.
3. Connect wires according to the
electrical diagram.
4. Connect power supply circuit.
ELECTRIC DIAGRAM
FUNCTIONING
The EW-01 device functioning is based
on the SDM-10 bell controller working
algorithm. In order to adjust any setting
(programming) it is necessary to read the
SDM-10 instruction manual.
The Electronic School Bell is tted with
three external wires:
1. Power supply - for 230 V AC power
supply connecting;
2. Output: bell - for 230 V AC bell di-
rect connecting (connecting diagram
no. 1);
3. Output: bell system control button -
for connecting the device instead of a
bell button mounted previously (con-
necting diagram no. 2).
The switch disconnector (1) is designed
for the device switching ON/ OFF.
The control button (5) is designed for
normal / short lessons changeover.
The control button (6) is designed for
generating alarm signal manually.
BELLS
The EW-01 is capable of cooperating with
the following ZAMEL bells:
1. School / Alarm Bell, large
DNS–212D (230 V)
DNT–212D (24 V)
2. School / Alarm Bell, small
DNS–212M (230 V)
DNT–212M (24 V)
