MR-223 employs a single circuit.
So this alarm system is applicable to a small area where safety is mattered due to gas work.
This model along with a shutdown device can constitute a gas leak alarm/shutdown system.
This combined system allows that the gas valve seals off automatically in the event of gas leak.
