A fire protection system includes a pipe system in fluid communication with a water source. A local processing unit is operatively coupled to a radio frequency identification (RFID) tag reader antenna. Sensors monitoring a sensor area for the presence of a fire are in electrical communication with the local processing unit. Fluid distribution devices in fluid communication with the pipe system are configured to deliver water from the water source to the sensor area. An RFID tag apparatus is coupled to one of the fluid distribution devices and includes an RFID tag antenna positioned within the pipe system and is configured to transmit and receive radio frequency (RF) signals to and from the RFID reader antenna and local processing unit, through the pipe system.

A corrosion monitoring system of a fire protection system includes at least one first antenna and a processing circuit. The at least one first antenna receives a radio frequency (RF) signal through an internal volume of at least one pipe of the fire protection system. The processing circuit includes one or more processors and memory including computer-readable instructions that when executed by the one or more processors, cause the one or more processors to determine a signature of the RF signal, compare the signature to an expected signature, and determine, based on the comparison, that corrosion in the at least one pipe has occurred.

A communication system includes a first radio frequency identification (RFID) device coupled to a sensor that monitors a fire condition and a second RFID device. The first RFID device includes at least one first antenna that receives a fire detection signal from the sensor, and a processing circuit that causes the at least one first antenna to transmit a radio frequency (RF) signal corresponding to the fire detection signal through an internal volume of a pipe coupled to a fluid source. The second RFID device includes at least one second antenna that receives the RF signal through the internal volume of the pipe. The second RFID device controls operation of a fluid distribution device responsive to receiving the indication of the fire detection signal.
