Light Weight – Through the use of the latest weight saving technologies, Firecom is able to deliver a wireless headset that is lighter than many wired communication headsets. Long Battery Life – With over 24 hours of battery life on DECT7 Headsets, the headsets work whenever the user needs it. Multimode Auto Shutdown – For user convenience, the Headset is designed with multimode auto shutdown to extend the life of the batteries. All of the shutdowns have a verbal announcement and may be cancelled by the user by pressing any button. Noise Cancelling Microphone – The microphone is a noise cancelling type designed to remove the background noise right at the mic element. This allows listeners to hear the person talking and not the background noise. Two Stage Low Battery Alert – The powered headset has a two stage low battery alert system to notify the user when battery is nearly depleted. This allows the user to have adequate notice before loss of communications. USB Programmable – The headset has a built in USB port to configure your headset with a Windows PC.

Voice Prompts – The voice guided menu prompt system allows the user to make all adjustments without removing the headset. There is no need to look for lights, text, or knob positions. The voice prompts automatically adjust volume to ensure intelligibility in changing environments. Wired Line-in – The wired line-in is used to interface with cell phones. This gives the user another source for flexibility in their communication needs. The wired connection features a mono input and output with PTT output. See your Firecom dealer for accessories to match your equipment. Wireless DECT7 Communications – The headset 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 the Firecom WB505R Wireless Base Station. The DECT7 communication network gives the crew members up to 1,600 feet line-of-sight range to the wireless base. The standard further ensures interference free and digitally encrypted communications. Wireless DECT Backwards Compatibility – The wireless headset is backwards compatible with the Firecom first generation wireless DECT and DECT6 Wireless Base Stations with minimal loss in functionality. Wireless DECT7 Broadcast Mode – Connect in listen-only mode allows up to 100 DECT7 headsets to be connected to a WB505R Wireless Base Station simultaneously. Pressing the PTT button allows the headset to momentarily talk on any available open slot on the base station. A tone will let the user know when they can talk. Refer to the WB505R manual for details. Wireless DECT7 Dual Dome Antenna Design – Each dome has a separate DECT7 antenna using diversity switching to lock onto the best signal. This means the user doesn’t need to worry about head position relative to the wireless base and the best possible connection is delivered at all times. Wireless DECT7 Encryption – using the latest digital encryption available, the DECT7 headsets ensure your conversations are private. Wireless DECT7 Out of Range Warning – The headset notifies the user via voice prompt when the wireless connection is weak, or when it appears to go out of range from the Wireless Base Station. 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.
