Whether you’re inside the truck or outside at the pump panel, doing a 360 of a building, assessing extractions – stay in constant communication with the UHW505 from Firecom. DECT7 wireless technology delivers improved voice clarity. Stereo listen-through microphones provide situational awareness without removing your hearing protection.
Adjustable Volume Control – The headset has a programmable and real-time adjustable user volume control. The Headset will remember the last setting at each power up for convenience.
Auto-Leveling Microphone – The headset automatically detects the voice of the user against the noise in the background. This allows the headset to have an automatic VOX (noise gate or squelch) that needs no adjustment when transitioning from areas of differing noise levels.
Automatic Loud Noise Suppression – The headset limits high impulse events such as gun shots from being transmitted to the user when using the Stereo Listen Thru.
Silicone Ruggedizers – Define positions or roles with these colorful ruggedizers. Fits over each ear dome to provide additional impact and abrasion resistance. Available in 14 standard colors (sold separately).
Extreme Environmental Design – Despite the rain, snow, mud and soot, the UHW505 performs when you need it most. Operates to -22°F/-30°C for extreme cold weather environments.
Hearing Protection – The headset conforms to many of the required hearing protection standards protecting the user from harmful noise.
In Headset Charging – The powered Headset has charging circuitry built in and is ready to be charged from multiple sources. These include the supplied AC wall adapter and DC charging options from a variety of sources including most cars, trucks, and aircraft. Refer to specification for charging voltages and power requirements.
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.
Listen-Through Situational Awareness – The headset has stereo listen through microphones to give the user full situational awareness. The microphones are placed on the forward edge of the headset to give the user the perception of sounds in the front versus from the rear. The listen through has a programmable volume level and will limit all sounds to 82dB to the user.
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.
Radio PTT – The headset interfaces with any two-way portable radio using the wired AUX input or wireless DECT connection. When there is a wireless DECT connection, the PTT signal is passed to the wireless DECT7 Wireless Base Station and onto the Digital Intercom. Otherwise, the PTT signal is passed to the wired AUX input.
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. Many of the features may be customized and saved from the program. Refer to the Firecom Headset Program for details.
User Replaceable Battery – The powered headset uses a replaceable battery. This allows the user to replace the battery at end of life and have spares in the field for extended operation times.
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 and hand held radios. 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 Sonetics 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 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 Radio PTT or Intercom Only Selection – The headset may be configured to send a transmit signal to radios connected to the DECT7 Wireless Base Station and Intercom of a Sonetics DECT7 wireless communication system. This allows the user to transmit over multiple radios depending on the Wireless Base Stations and Intercom configuration. Additionally, the Headset may have radio transmit deselected. This is excellent for teams where some users will need radio transmit and others will not.
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.
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.
