Ambulance and associated vehicles may have gasoline or diesel engines.
Gasoline engines will have carbon monoxide (CO) concerns and diesel engines will have nitrogen dioxide (NO2) concerns. The EC-Gold Dual series offers both gas sensors in one compact unit. The alarm levels are adjustable to your local code requirements and on-board relays can operate ventilation fans. A buzzer with silence is standard on all units should levels continue to rise after the fans have initiated.
