dect7 Wireless DECT7 Communications – Features a wireless DECT7 communication channel enabling full duplex communication, like a conference call, to others on the same channel. Firecom wireless DECT7 headsets connect with standalone Firecom DECT7 Wireless Base Stations. This DECT7 communication network gives the user up to 1,600 ft. line-of-sight range to the wireless base. The standard further ensures interference free and digitally encrypted communications among all parties.
dect7 encryption Wireless DECT7 Encryption – using the latest digital encryption available, the DECT7 headsets ensure your conversations are private.
dect7 multi-channel system Wireless DECT7 Multi-Channel System – Depending on the wireless DECT7 Wireless Base Station or IP-DECT7 system, the user may have access to multiple channels. This allows large teams to have separate channels for different activities while enabling users to change channels and become one communication team. Refer to the Wireless Base Station manual for configuration.
dect7proximity pairing Wireless DECT7 Proximity Pairing – To enhance security, the Wireless Base Station will only pair to wireless DECT7 units in close proximity. This adds another layer of protection for users.
dect7 wide band audio Wireless DECT7 Wide Band Audio – The wireless DECT7 communications are transmitted in a high definition wide band audio format. This allows greater intelligibility of the user and integration with voice activated control systems. This feature is defeatable to allow the user to be in a narrow band audio communication.
dect 7 broadcast mode Wireless DECT7 Broadcast Mode – The headset may be paired into a listen only mode of operation, reducing power consumption considerably. This also allows many more headsets to be connected to a Wireless Base Station simultaneously. Pressing the Radio PTT button allows the headset to momentarily talk on any available open slot. A tone will let the user know when they can talk. Refer to the Wireless DECT7 Base Station manual for details.
