Description:
Your DataPage Mark 2 is supplied in one of six configurations:
1) NDPUSA, the basic model, provides keyboard entry of data for message transmission. Additionally, two volt-
free (dry) contacts are provided for sending pre-programmed messages. These contacts can be programmed for
normally open, normally closed or change of state operation (see page 3, Dry Contacts).
2) NDPMFUSA: as above, with the addition of an interface suitable for connection to an internal telephone
system that is driven by DTMF tones i.e. all internal telephones on the internal exchange must be capable of
sending dual tone multi frequency signals (DTMF) from their own keypads to the extension socket selected to
operate the paging system. The vast majority of PBX telephone exchanges operate in this way.
3) NDPLPUSA: as above, but for connection to hybrid systems that use four wire telephones and their own
proprietary digital signaling protocol. In most cases, these systems will not be able to send DTMF tones from all
internal telephones to the selected internal two-wire extension socket. The NDPLP model is therefore configured
for connection to a spare
external line port by way of the AB wire. The telephone exchange must then be
programmed such that this line port is not automatically selected when requesting an external line, but
