Gas Meter room, for this room the possibility of gas build-up has to be considered for this reason if the gas meter room need fresh air ventilation that must be monitored to ensure it is always running. To check for operation the usual thermal and current overloads are not considered good enough so an air pressure sensor located in the fan duct is included. As the fan is often very small the pressure sensor has to be very sensitive and may need shaped duct probes on both the air on and air off sides of the fan motor. Audible and visual alarms are also included to operate if the fan fails. If using our fast fit system, you may choose product ABC SW3-GM-A or SW3-GM-B if you need a complete gas meter fan control system consider our ABC FFC-R1-GM1-V1

, these are probably the most important fans in the building as under normal building operations they are not used BUT when there is a fire in the building (GFA) they are expected to operate and supply fresh air into the stair well to assist people to evacuate. For this reason, I prefer to keep the system as simple as possible so there is less to go wrong when the fans are needed. Before installing a control system, it is best to completely read the fire engineers report on how exactly they expect the fans to operate. These fans are usually speed controlled by a Variable speed drive (VSD) or in some cases the fans work at full speed and relief dampers operate to modulate the air pressure. We can help with the pressure sensors try our SEN P6 series and the control units such as our ABC SW4-SP-A and our ABC SW4-SP-B. Or talk to us about our complete stair way control systems
