## ✅ Key Features & Capabilities of DSC Impassa

- **Up to 64 wireless zones + 16 wireless keys** — the large zone capacity allows many doors, windows, motion detectors or devices to be connected.

- **Integrated cellular (HSPA 3G) communicator (optionally with IP/dual communicator)** — offers reliable remote signalling over cellular (or internet) rather than relying on a traditional phone line.
- **Built-in 2-way audio / VOX + push-to-talk support** — during an alarm or alert, enables direct voice communication via phone line or cellular, adding a level of response beyond just sirens.
- **Support for multiple wireless devices** — system supports up to 4 keypads, 4 sirens, 16 key-fobs (wireless keys), giving flexibility in where devices are placed.
- **User convenience features** — includes up to 17 user access codes, a 500-event memory buffer (event history), easy wireless device enrolment, programmable labels and function keys.
- **Flexibility and scalability** — because it’s wireless and modular, you can expand or reconfigure sensors without rewiring. This makes the system well-suited for retrofits, rentals, or spaces where wiring is impractical.
