Keypad w/ 2-Way Audio

In no time, this DSC alarm system's keypad will become your home's central command center. Instead of bulky hardwired control panels and external speakers- this keypad contains it all. The soft-touch buttons on the keypad allow you to activate/deactivate this system and fast-action emergency keys are instantly accessible should a frightening situation arise.

In emergency situations, you'll be glad you have the 2-Way Audio feature. Built-in to the keypad is a loud speaker and microphone, allowing you to quickly and clearly communicate distress to a central monitoring station. Most home alarm systems simply aren't capable of this kind of protection.


Installation and Expansion

Installation for this wireless alarm system is a breeze for any do-it-yourselfer. Only 1 wire is needed (AC power for the keypad) and the rest of the wireless accessories help to keep your home looking great with no wired disruptions. Enrolling the devices is a user-friendly experience as well with simple keypad programming- and the benefits don't end there. With 64 wireless zones, add more accessories at will. Especially useful if you move to a larger home and want to up your alarm system. With the DSC Impassa, begin enjoying today's technology with a plan for tomorrow's capabilities
