This is meant to be connected at Way Side Stations working on DTMF Signaling on 2 wire basis. It consists of a DTMF Receiver, Code Setting and Group Call DIP switches and associated logic circuitry. The equipment is housed in a metal cabinet. Whenever a way station is called the piezo buzzer is activated and a ring back tone is sent to controller. Each way station is assigned a 2 digit code. It is possible to assign station codes from 01 to 99. The equipment works on 12 V DC Power supply. A suitable Maintenance free battery along with charger can be provided on request (optional).
