Part of DSC's family of self-contained wireless controls, the DSC Impassa features a LED screen with programmable function keys for easy operation. This DSC Impassa kit includes a built-in dual path alarm communicator that utilizes the primary internet/ethernet network, and if down, the backup AT&T cellular network to transmit Telular HomeControl compatible interactive alarm signals. With only one wire needed for AC power, installers need to drill fewer holes and pull fewer wires, reducing the on-site installation time. Using the Impassa 2-way control panel also reduces the time spent enrolling compatible wireless devices. Installers confirm electronic serial numbers (ESN), zone numbers and zone types through a series of user-friendly screens. In addition, the Impassa template programming feature allows installers to quickly program basic functions by just entering a 4-digit code. Codes exist for pre-defined zone definitions, reporting code formats, communication call directions and DLS setup. Lastly, the installer needs to activate the Telular HomeControl dual-path communicator, DLS access code, entry/exit delays and installer code.
