This High-quality 3-modcomp Edwards Modem / Communicator Device [51TtnBJQ] offers efficient communication and connectivity with a compact design that takes up minimal space. Equipped with tap protocol and a pager interface for easy integration, this modem is a reliable solution for seamless data transfer.

The Modem Communicator is a two-way local rail module that performs a variety of off-premise communications functions for the system. Using the latest in digital signal processing (DSP) techniques, the Modcom provides off premise communication features unavailable on any other system. The module has provisions for supervising two loop-start telephone lines. The module features a modular jack for telephone line connections. The Modcom’s configuration and firmware can also be updated from any network node. Modcom series modules occupy a single local rail space and can be mounted in any panel on the network. Most system Control/ Display modules can be mounted in front of the Modcom series module. Power for the Modcom is supplied by the system power supply. The Modcom provides an enhanced level of survivability in the event of a network CPU failure by notifying the Central Monitoring Station of the failure and entering a degraded mode of operation. In degraded mode, the Modcom can transmit a default fire alarm message during a fire alarm condition. With its advanced features and reliable performance, the Modcom series is the ideal solution for mission-critical communication systems, offering unparalleled flexibility and survivability for demanding applications.
