Regarding the power supply for combustible and toxic gas detection probes
Thread Content
The combustible and toxic gas control cabinet is located in the fire control room, as is the UPS power supply. It is far away from various work areas; the straight-line distance in some cases exceeds 400 meters. How will the power for the sensors be supplied? Can the 24VDC power supply specifically designed for fire protection systems be used for the fire alarm system on site? The specifications require that the probe be powered by a UPS; this fire protection system uses a 24VDC power supply that feeds the battery. I’m not sure if this counts Also, are there any requirements regarding the UPS battery life?
On our side, there are toxic substances; the gas detection system cabinets (GDS), along with the DCS and SIS, are located in the cabinet room, while the control computers are placed in the fire control room.
