DSC SCW457J IMPASSA Stand Alone Unit, Includes 64-Zone Self-Contained Wireless Alarm with Built-in Two-Way Voice, JP1000 Telephone Jack and Cord, PTD1640U Transformer, and SCW-BATTERYHC Battery

Protect facilities and residences with a turnkey security communicator that prioritizes reliable monitoring and rapid deployment. The DSC Impassa SCW457J standalone alarm communicator delivers two-way, 3G-ready cellular and phone-line communications with built-in two-way voice for alarm verification and remote interaction. Designed for installers and security managers, this self-contained system supports up to 64 wireless zones and 16 wireless keys, enabling broad intrusion detection coverage without extensive wiring. The distributed wireless design means you can conceal the main panel while positioning WT5500-style keypads and sirens at entry points—making tampering less effective and improving overall site response. Included accessories (JP1000 phone jack/cord, PTD1640U transformer and backup battery) speed commissioning and reduce truck rolls. With template programming and simple device enrollment, technicians can program common zone types and reporting formats with a few keystrokes, cutting install time. Ideal for small commercial sites, multi-family units or high-value residences requiring professional monitoring, surveillance integration and alarm communication redundancy.
