Same problem as the single-sensor unit, but you get coverage in two spots. Stove end and hot water end. Or bilge and galley. The Peel MD-220 flush-mounts into your fascia — no large cutouts — and the solenoid cuts the gas the instant either sensor flags dangerous levels. Two sensors: one on a 4-metre lead, one on a 6-metre lead. Relay contacts and a CO detector input are in the box. Two eyes on the gas where it matters
