3-MODCOMP – Modem Communicator with Paging
The 3-MODCOMP is identical to the 3-MODCOM except for
the inclusion of the TAP paging protocol. The end user must
subscribe to a TAP-compatible alphanumeric paging service.
Depending on the paging service provider, the TAP message can
be broadcast via radio to a pager, converted to an e-mail, or
faxed to an end user.
The module is supplied with two seven-foot cables (P/N 360137)
for connecting the 3-MODCOMP to an RJ-31 jack. You must
obtain the RJ-31X jack locally, and wire it to the telephone lines
as indicated on the 3-MODCOM installation sheet.
RJ-31X jack – telephone company jack
An RJ-31X jack must be used to connect each line of the
3-MODCOM to the switched telephone network. One jack is
required for each telephone line.
The jack is an eight-position jack with a special jumper between
terminals 1 and 4 and 5 and 8. This jumper is in effect when the
plug is removed from the jack.
Removing the plug re-establishes connection to the premises
telephones. Inserting the plug opens the jumper and connects the
3-MODCOM, which provides a series connection to the
telephones.
Refer to the 3-MODCOM installation sheet for a diagram of the
jack wiring.
Note: Failure to use an RJ-31X jack violates FCC and NFPA
regulations. A telephone connected directly to the incoming
telephone line without the proper use of the RJ-31X jack will
cause a telephone company trouble when used and possibly
prevent the dialer from getting through to the CMS receiver in an
emergency.
Configuration options
3-MODCOM and 3-MODCOMP can be configured as:
• One-line dialer
• Two-line dialer
• Modem
• Modem and one-line dialer
• Modem and two-line dialer
For UL listed or FM approved installations, you must configure
the 3-MODCOM as a two-line dialer, and both lines must have
supervision (line-cut detection) selected.
The 3-MODCOM operates in accordance with programmed
instructions. Details of items such as telephone numbers, dialing
