CO2 Mk90 Sensor Add-on KIT

Art no: 2119

MK90 CO2 Sensor KIT
This complete plug and play KIT can be used to add an additional sensor to an existing LogiCO2 Safety System. The Mk90 detector has an integrated Horn and Strobe that activates in case of an alarm and warns people in the area of the alarm. The sensor is pre-set to ID2 and receives its power from the existing Safety System. LogiCO2´s Mk90 CO2 Sensor measures the CO2 concentration and alerts in the event that CO2 concentration reaches the pre-set alarm levels. When installed, the system will continuously monitor the CO2 concentration in the room or area where the CO2 sensor is located. It contains a Mk90 CO2 Sensor with display, a Horn/strobe, cabling and signage. Up to eight sensors can be connected to a LogiCO2 Safety System, providing a sophisticated and powerful CO2 Safety System while still being the most economical and easiest system on the market. All LogiCO2 sensors have automatically calibration as standard. The alarm levels can be changed to any level to comply with all local Safety Codes and legislation.

The pre-set alarm levels are:
– 5000 ppm instantaneous Alert
– 5000 ppm TWA 8Hr (PEL)
– 1,5% (15.000 ppm) ½ STEL
– 3,0% (30.000 ppm) STEL

What is in the package?
CO2 Mk90 detector + Horn/Strobe LED with cable + 10 m power/ communication cable + plug lock + 5m signalization cable + 1 RJ45 1‐1 connector + 1 RJ45 1‐4 connector + manual + H/S sign.

Please note:
A separate installation manual is provided with each extra CO2 sensor kit explaining the simple installation process for adding additional sensors to an existing set.
