Keonn AdvanSafe-300 Secondary Unit | Upper Band Ceiling Mount

Traditional loss prevention systems at store entrances can be bulky, intrusive, and prone to false alarms, slowing down shoppers and frustrating staff. The Keonn AdvanSafe-300 Secondary Unit works alongside a primary unit to extend your overhead RFID loss prevention coverage across wider store entrances without adding complexity or clutter. The ceiling mount design installs flush to the ceiling for a clean, low-profile look that keeps your entrance completely free of obstacles while delivering continuous, reliable EAS detection using standard Gen2 UHF RFID tags.

Designed for scalability, each secondary unit pairs with one primary unit to cost-effectively cover broad entry points in retail stores and warehouses. The ceiling mount installs at a recommended height of 2.5–3 m (8.2–9.8 ft), and with Power over Ethernet connectivity, cabling stays simple. The unit includes a visual LED alarm and integrates smoothly into your existing AdvanSafe loss prevention setup, giving your team expanded detection coverage without expanding your footprint on the floor.
