The APPI-Com is an advanced, professional-grade wireless intercom engineered to deliver reliable, hands-free communication for teams operating in the most high-risk, confined, and noisy environments.
Utilizing Full-Duplex technology, the APPI-Com enables natural, conference-style conversation, maintaining crystal-clear audio quality across physical barriers (walls, floors) and over exceptional distances—up to 3.8 kilometres (2.3 mi)
Designed to integrate effortlessly with your operations, the unit is lightweight, compact, and comfortable to wear alongside all personal protective equipment (PPE), ensuring safety and efficiency for teams of any size.
A unique and secure communication solution
The APPI-Com is the most compact solution in its class and activates your network at the press of a button. Thanks to SyncAll® technology, even if a radio drops out of the network—whether due to signal loss or being powered off—the rest of the team stays connected without disruption. With automatic reconnection, the device seamlessly joins the conversation with no manual intervention required.
For added safety, the APPI-Com includes built-in Lone Worker Protection, including:
- Immobility Detection: APPI-Com is embedded with a sensitive electronic motion sensor: once a lack of motion is detected, the APPI-Com produces an audible warning and a voice message to the entire group.
- Network Connection Failure: the APPI-Com’s Safeline® technology sends a notification to the team in case of a disconnection from the group.
- User-Activated Alerts: With the press of a button, users can activate the integrated pager to call attention to their team.
- Compatible with any HALO Pro® intrinsically safe-rated series Headsets. More than 10 choices available.
