Abstract

A method for attaching a relay module to a fire hydrant comprises positioning the relay module adjacent to the fire hydrant, the fire hydrant comprising a hydrant body and a bonnet coupled to the hydrant body by a plurality of fasteners, the bonnet mounted on top of the hydrant body, the relay module comprising a radio housing defining a top surface, a mast connected to the radio housing and extending upwards from the top surface, and a mounting bracket attached to the top surface, the mounting bracket engageable with the hydrant body; and securing the relay module to the fire hydrant such that the mounting bracket and a portion of the top surface is positioned beneath the bonnet.

First claim

The invention claimed is:

1. A method for attaching a relay module to a fire hydrant comprising:
positioning the relay module adjacent to the fire hydrant, the fire hydrant comprising a hydrant body and a bonnet coupled to the hydrant body by a plurality of fasteners, the bonnet mounted on top of the hydrant body, the relay module comprising:
a radio housing defining a top surface,
a mast connected to the radio housing and extending upwards from the top surface, and
a mounting bracket attached to the top surface, the mounting bracket engageable with the hydrant body; and

securing the relay module to the fire hydrant such that the mounting bracket and a portion of the top surface is positioned beneath the bonnet.

2. The method of claim 1 , wherein the radio housing defines a concave surface which conforms to an outer surface of the hydrant body, and positioning the relay module further comprises positioning the concave surface of the radio housing adjacent to and facing the outer surface.

3. The method of claim 2 , wherein positioning the relay module further comprises:
positioning a back casing of the radio housing beneath the bonnet, the back casing defining the concave surface of the radio housing; and
positioning a front casing of the radio housing external to the hydrant body and the bonnet, the mast connected to the front casing, the mast extending upwards above the hydrant body.

4. The method of claim 3 , wherein positioning the relay module further comprises providing a consistent gap between the back casing and the hydrant body, the gap configured to allow for expansion and contraction of the hydrant body.

5. The method of claim 1 , wherein the mounting bracket defines a concave surface, and positioning the relay module further comprises positioning the concave surface of the mounting bracket adjacent to and facing an outer surface of the hydrant body.

6. The method of claim 1 , wherein the hydrant body defines a bonnet-mounting flange, and wherein securing the relay module further comprises positioning the mounting bracket in facing contact with a bottom surface of the bonnet-mounting flange opposite from the bonnet.

7. The method of claim 1 , wherein the mounting bracket defines a mounting fastener hole, and wherein securing the relay module further comprises inserting a one of the plurality of fasteners into the mounting fastener hole.

8. The method of claim 7 , wherein securing the relay module further comprises tightening a nut on the one of the plurality of fasteners received by the mounting fastener hole.
