Optio™ BGM

MULTI-GAS MONITOR FOR LI-ION BATTERY SAFETY​

The Optio BGM is a multi‑gas detector engineered to monitor Li‑ion battery systems for early signs of thermal runaway. The Optio BGM incorporates three dedicated sensors to continuously monitor for carbon dioxide (CO2), hydrogen (H2), and volatile organic compounds (VOCs) to detect batteries which may be venting before visible smoke or flame appears. Onboard relays, 4-20mA outputs, and Modbus communication makes it easy to integrate the Optio BGM with the Primus V Controller as a part of a building’s overall safety solution.
PRODUCT FEATURES
  • Primus V Integration – Multiple Optio BGM detectors can connect to a Primus V controller for centralized monitoring, building automation system integration, and fan, louvre, or exhaust control.
  • Long Sensor Life – Designed for extended operational longevity, reducing replacement frequency and lowering maintenance costs.
  • Self-Diagnostic Function – Continuously monitors internal health to ensure reliable system performance and early fault detection.
  • Automatic Reset – Recovers seamlessly after power loss, minimizing manual intervention.
  • Dual Onboard Relay Contacts – Provides two built-in relays for direct control of external devices and alarm functions.
  • Optional Dual 4–20 mA Outputs – Offers two analog outputs for integration with building management or automation systems.
  • Onboard 85 dB Alarm – Delivers a loud, clear audible warning to alert personnel to hazardous conditions.
  • Bright LCD Display – High-visibility screen ensures clear viewing of gas readings and status information in various lighting conditions.
  • Hydrogen (H2)
  • Carbon Dioxide (CO2)
  • Volatile Organic Compounds (VOCs)
