Trust and Reputation

Designed specifically for the do-it-yourself home or business owner, the DSC Impassa Self-Contained 2-Way Wireless Security System has a near perfect design and is backed by the long and trusted reputation of DSC. This wireless security system was built with simple installation in mind, without cutting back on anything you'd need for a solid alarm system. Showcased in this full-proof kit are a user-friendly keypad, 5 impressive alarm accessories and the wireless flexibility of keeping your home tidy and protected at the same time.

Keypad With 2-Way Audio

This DSC alarm system's keypad will feel like it was worth the investment in no time. 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 the 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 can't compete with this well thought-out keypad design.

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.

Included Accessories

(1) Wireless Passive Infrared Motion Detector: The detector is usually stationed in the family room for wide coverage and is pet-immune. Pets up to 60lbs. can roam freely without triggering the sophisticated Infrared tracking system.

(3) Wireless Door/Window Contacts: Protect 3 entry points on your property in style. These transmitters are thin, flush with most home decor and have a 3 year battery life with favorable operating temperatures for different room conditions.

(1) Wireless Keyfob: Arm and Disarm your system after you exit and before you enter your home. The keyfob attaches to a key ring, has a panic button for emergency situations and will no doubt make remembering to activate your home alarm system much easier.

Maybe there's been some strange activity in your neighborhood recently. Maybe someone you know has been a burglary victim. Whatever the itch, this full-proof home alarm system will put your nerves at ease. Comprehensive and reliable, the DSC Impassa is your ticket to a new sense of security and protection.
