DCO-S1 is a digital ventilation controller specifically designed to monitor carbon monoxide and temperature in the enclosed or semi-enclosed car parks and to regulate the environment according to these two parameters. It can be used either as a control of the ventilation system or be a part of an alarm system.

Principal of operation

State-of-art hybrid thick film sensor (MMOS) with built in carbon filter measures carbon monoxide gas in parts per million (ppm), with flexible demand controlled ventilation (DCV) features. 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. Precision NTC temperature sensor is used.

Features

• Dual functional sensing and controlling of CO & Temperature in ambient air with programmable control settings.
• Saves energy costs with flexible demand controlled ventilation (DCV) features.
• Two sensor analog outputs 0-10V or 4-20 mA) for connection to remote central computer and/or alarm panel.
• Two sensor relay outputs (normally open contacts) for complex local On/Off and/or stage controls.
• Longer maintenance interval with internal microprocessor control and built in self correction algorithm (SCA). Typical maintenance interval > 2 years.
• Built in temperature compensation on CO measurement
• Removable terminal block for easy installation.
