Abstract

This invention relates to a fire hydrant locating system which includes a hydrant locator that facilitates the location of a hydrant by firefighters, particularly in an emergency vehicle such as a fire engine. The hydrant locator as secured to the hydrant cylinder has a low profile. The hydrant locating system includes a transmitter adapted to be located in the emergency vehicle. Upon actuation of a switch in the transmitter in the emergency vehicle a receiver-signal generator in the hydrant locator will be activated to set off strobe lights to alert firefighters of the hydrant location. The receiver-signal generator in the hydrant locator includes a strobe light structure. The transmitter can be set such that when actuated it will activate only those hydrant locators within a preselected range such as approximately 1500 feet.
