DCO-S3 is specially designed for enclosed and/or semienclosed car park ventilation applications. It can be used both to control the ventilation system and/or be a part of an alarm system. It is well known that all automobile engines generate CO and that we shall be protected against this toxic gas. By measuring the CO level in the car park and regulate the ventilation so as to keep the CO level below the recommended limit, the most cost effective ventilation system may be derived. In tropical areas where temperature comfort can be a concern, temperature measurement can be the second controlling parameter. When the temperature in the car park has risen to a preset limit, the ventilation can be used to create the wind effect so as to improve the comfort level. DCO-S3 is intended for wall mounting.

Applications
DCO-S3 is used in carparks, car repair shops, tunnels, engine test stands, shelters, loading bays, go-kart race courses and also in boiler rooms, in which carbon
monoxide can escape on the basis of a leak in the exhaust system.
