Radius® BZ1 Area Monitor

Built for the world’s harshest environments, the Radius® BZ1 Area Monitor is always working – even when you’re not at the location. With the ability to leave the area monitor in the field for nearly two months on battery or indefinitely with external power supplies, you can control and monitor up to seven hazards anywhere across your site – ensuring the right level of response when workers are exposed to those dangers.

Plus, with the ability to seamlessly share alarms between monitors, you can rest assured that someone’s always got your back.

Up and Running, Even When You Aren’t

• Runtime up to 50 days on battery (based on configuration)*
• Unlimited runtime with external power supply options
• Removable sensor module – leave the device in the field and minimize downtime by swapping ready-to-use sensor modules without removing the entire device from its location

Make Quicker Decisions

• Customizable alarm messages such as “EVACUATE” or “VENTILATE”
• Seamlessly share alarms between personal and area monitors across an entire site with our LENS™ Wireless technology
• Ensure accurate readings and reduce false alarms by relying on two sensors to detect the same gas with DualSense® technology

Trusted Reliability to Keep Teams Safe

• Get more accurate detection with all-weather sensor options and the ability to detect gases across a 360-degree path
• Reliably alert workers to all hazards with:
  • Bold LED lights
  • Alarms that sound at 108dB, cutting right through any high-noise environment
  • Large, easy-to-read display

Maximize Team Safety (LENS Wireless)

LENS Wireless is a local team-based peer-to-peer (P2P) communications that gives your team improved hazard awareness that leads to faster emergency responses. Devices connect within seconds after being turned on – with no need for IT setup, configuration, or additional infrastructure. Simply link devices to form a connected group of monitors to create a dynamic safety net across your worksite. Devices will communicate between one another even in the harshest environments.

SafeCore Sensor:

Each piece of critical technology for the Radius BZ1, such as sensors, software, pumps, and wireless configurations, live inside the SafeCore® module. This smart sensor is positioned face down to prevent the elements from interfering with gas readings, resulting in fewer false alarms – even in the harshest environments. The module also slides out from the Radius base for easy docking and automated maintenance, ensuring that your sensors are always ready to go. Plus, you can even swap sensors out in the field, so the Radius base never has to leave its spot.

DSX Docking Station:

Manual maintenance and record keeping are time-consuming and prone to error. The DSX Docking Station is a cloud-connected solution that gives you complete control to schedule maintenance and firmware updates – so your area monitors are always ready when you need them. Plus, the DSX Docking Station can automatically perform any calibrations needed for your SafeCore sensor.

RGX Gateway:

The portable RGX™ Gateway transmits location, gas readings, and real-time alerts from anywhere, including hazardous locations, giving you the power to respond faster and to improve site productivity. By using the Radius BZ1 and the RGX Gateway, you can ensure your information is always backed up and available on the cloud – making it easier to access wherever you are.
