Regulator Systems Carbon Monoxide (CO) Smart Sensor
The CO3800 Carbon Monoxide smart sensor is a slim wall mounted sensor with a very unique feature. It has a tiny fan that draws air in from the bottom of the housing through a dust filter over the sensor and discharges through the top. This ensures a positive response to carbon monoxide emissions while the sensor is well protected inside the polycarbonate housing.
The CO3800 sensor operates on a two wire non-polarised connection to the TC5044 controller. Power and communications are supplied over one pair of wires. Up to ten CO3800 sensors can be connected to the one controller. (Note: Earlier models were limited to six CO3800 sensors). There are two 4 position DIP switches on each sensor. DIP Switch 1 is for setting the address for each sensor. The CO level for each area can be read at the controller. The controller will recognise how many sensors are connected will select the highest CO level to control the carpark ventilation fan(s). If the DIP switches are not set, then the controller will allocate an address to each sensor, however the CO Levels for each area will not be available, only the highest CO level detected. DIP Switch 2 is for the selection of the analogue output. 1 – 4-20mA. 2 – 0-10vdc.
Each CO3800 Carbon Monoxide sensor is calibrated as a group in a custom calibration chamber and a calibration label showing the following data is attached to each CO3800 sensor.
- Serial Number
- Calibration Date
- Calibration Reference in ppm.
