Fire hydrant locating system
First Claim
1. A fire hydrant locating system for facilitating location of a hydrant in an emergency area by personnel in an emergency vehicle, said locating system including:
- a hydrant locator unit adapted to be secured to a fire hydrant;
said hydrant locator unit including a receiver, locator secured in a housing which is adapted to be attached to the fire hydrant;
a transmitter, actuator adapted to be located in the emergency vehicle;
said transmitter, actuator including a transmitter being selectively actuable by an operator to transmit a radio frequency signal to assist in locating a fire hydrant near the emergency area;
said receiver, locator in said hydrant locator unit as attached to the fire hydrant including a receiver adapted to receive the radio frequency signal from said transmitter;
said receiver, locator including light emitting apparatus for transmitting a flashing light to signal the location of the hydrant locator unit and the associated hydrant, said receiver, locator including a battery for providing power to the apparatus in said receiver, locator including said receiver and said light emitting apparatus, said receiver, locator being programmed to cyclically energize said receiver to continuously cycle to be on in a wake mode for a preselected period to receive the radio frequency signal and off in a sleep mode for a preselected period, upon receipt of a radio frequency signal by said receiver from said transmitter when in a wake mode said light emitting apparatus will be actuated to be on to provide a flashing light signal for a preselected time and then actuated to be off for a preselected time with the cycle being repeated for a preselected time.

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.
