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.
