MOWE'S FIRE DETECTION SYSTEM
MOWE's Fire Detection System is designed to monitor the status of connected devices on addressable loops for fire alarms, short-circuit faults, open-circuit faults, unauthorized removal and detector or sensor fault conditions.
MOWE'S GAS DETECTION SYSTEM
Flexible gas monitoring and alarm management for hazardous marine and offshore environments.
Gas detection systems monitor the protected area for combustible and toxic gases. Detector signals can be transmitted to the Fire & Gas control system for alarm monitoring, detector status indication and system fault monitoring.
Depending on the selected system configuration, gas detection signals can be provided through 4–20 mA and Modbus RS485 interfaces, with HART communication available as an optional interface where required.
Typical project configurations can support hydrocarbon gas detection from 0–100% LEL and hydrogen sulphide (H₂S) detection from 0–100 ppm.
