 Product 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 disconnector, 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 automatic mode according to the preset algorithm. The program preparing is being held by means of entering lesson and break times, and beginning time.

The system is ready to implement some specials functions (alarm bells, short lessons) by means of programmable control inputs.
