Niche telecommunication devices, audio products and door phones
The DS3 is an indoor control module that can be used with any of the Natcomm door phone range, DP2, DP3 or DP5. The DS3 provides an analog (PSTN) connection (line in port) and has a phone extension port (line out port) for connection of a handset that can be used to take calls from the door phone. In the absence of a door phone call the handset connects to the line in port.
The unit includes an internal 5REN ring generator to ring connected analog phones when a visitor presses the door phone call button. After answering the call, the phone keypad can be used to allow entry by operating one or two relay contacts within the DS3. The DS3 also includes DTMF dialling of a programmed number (land line, mobile or SIP) on a call button press.
