Fire Extinguishers
Fire extinguishers should be checked every 30 days to make sure all the canisters are
charged and pressures are correct. Instead of checking the extinguishers manually, in a
ZigBee-based monitoring system a sensor is attached to each extinguisher to monitor its
status and wirelessly communicate with the coordinator when maintenance is needed. A
ZigBee-based monitoring system not only saves time and labor cost, it also helps improve
fire safety by immediately alerting authorities if a fire extinguisher is not working
properly.
