Product Overview
Wireless intercom has never been easier
The TR-240 is a full-duplex intercom beltpack working in the 2.4 GHz frequency range. It provides a very comprehensive, user friendly, and extremely versatile set of features to be custom configured to a user's specific requirements. It features the ability to be configured in one of 3 operating modes: wireless, wired, or master wireless:
- Wireless (normal) mode - beltpacks communicate to each other using the base station as a relay
- Wired mode - beltpacks turn off their wireless ability and communicate via Ethernet cable or through a building's existing Ethernet infrastructure
- Master wireless mode - the beltpack acts as a mobile access point to provide wireless coverage for other beltpacks to communicate without an actual BTR-240 base station (sold separately)
It also includes a removable lithium-ion battery pack that delivers up to eight (8) hours of uninterrupted operation. The battery pack can be charged directly within the case by plugging a power adapter into the beltpack or by placing the battery in the CHG-240 4-bay charger.
