Continuously monitors for combustible and carbon monoxide gas leaks.

The SMC 2400 Vault Gas Monitor detects combustible and carbon monoxide gas leaks to reduce the hazard of gas explosion and to maintain personnel safety. The monitor offers the gas detection functions required by telecom site managers including uninterrupted power supply, long-life sensors, five alarm relays, and both audible and visual alarm indication.

  • Solid State Semiconductor Technology - detects low points-per-million (ppm) levels of hazardous gas, maintain the life cycle of the product for long periods, easy maintenance
  • Electrochemical Technology - accurately detects toxic gases and consumes less power reducing operating costs
  • Uninterrupted Power Supply - consistently keeps the monitor running with the built-in constant current NiCad battery charger
