Function

Safety mode box (SMB) with safety valve is an accessory for the Mk9 and Mk90 CO2 Safety System that shuts off the CO2 gas distribution in case of a leakage. It consists of a magnetic valve, electronics box and cabling. The Safety valve is designed for usage of CO2 with a pressure of 0,15 to 30 bar or 2,2 to 435 Psi. SMB has a 1 meter Cat5 cable from the electronics
box, with a blue RJ45 connector that is plugged in to the blue alarm signalling output cable side from eitherthe Mk9 or Mk90 CO2 sensors. When the CO2 sensor indicates a high CO2 concentration, the magnetic valve will shut off the CO2 gas distribution. The valve is failsafe (shuts off at power loss). The magnetic valve should be installed as early as
possible in the CO2 gas distribution chain (close to the CO2 tank) in order to avoid possible CO2 leakage before the safety valve. Install the electronics box in a suitable place where it is mechanically protected. Remove the cover by turning it counterclockwise 1/8 turn to access the mounting screw holes

Installation

The connection diagram below shows an example of how the SMB with safety valve can be installed to a CO2 Safety System (Mk9 and Mk90).

Annual function control of the safety valve
To test the safety valve, make sure that the indication light on the valve is ON, indicating that the valve is powered on and open. Test the opening and closing of the valve by pressing the test button on the SMB connection box. The indication light on the valve should turn OFF and you should hear a clear clicking sound.
