The XT Series panel from Digital Monitoring Products of Springfield, Missouri, provides a complete set of communications options in an all-in-one, onboard design that offers increased capabilities with easier installation. Two models are available. The XT30 supports 10 onboard and 20 additional zones and includes a dialer. The XT50 is available with or without a dialer, and it supports 10 onboard zones, 20 wired zones, and 40 wireless zones for up to 50 total zones. Installers can order the panel configured with two-way wireless, network, cellular, and dialup communications. Cellular capabilities can be added later with the digital cellular communicator plug-in expansion card. Dealers can also add any DMP Wireless 1100D Series Two-Way Receiver on an existing XT30 Series installation.
