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:

• 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
