Installation Instructions, Base Station – KRC 101 1371

Note that mounting fasteners differ according to the building surface being mounted to.

When mounting to wood surfaces, standard 3/8" "lag bolts" are to be used. Generally however, buildings of concrete and/or brick construction are most common. In these cases the Mounting Plate must be secured with 4 expanding anchors suitable for this type of construction. Two types of expanding anchors are included in the kit and must be installed as follows:

Caution: Note that the correct anchor must be chosen for these types of construction and must be mounted in 3/8" holes drilled at least 1 1/2" deep.

For solid concrete:	ITW Ramset/Red Head "Trubolt Wedge Anchor"
For solid concrete,	Part No. WW-3822 Tightened @ 25.ft. lbs.
hollow concrete block,	ITW Ramset/Red Head "Dynabolt" Sleeves,
or brick:	Part No. SHN-3817 Tightened @ 15 ft. lbs.

Proper installation of the above fasteners provides more than 1300 lbs. of pull or shear strength (per fastener).

2.Secure the Base Station Mounting Bracket to the Inside of the Weatherproof Housing

See Figure 16-13. Locate the mounting bracket (supplied with the Base Station) in the position and drill two 5/32” diameter holes for mounting. Apply a small amount of silicon-seal to the surfaces. Next, secure the Base Station Mounting Bracket with two 6-32 x 5/8” pan-head screws, locking hex nut and flatwashers provided.

3.Secure Small Pattern Mounting Plate to the Weatherproof Housing Outer Surface

See Figure 16-14 Position the Small Pattern Mounting Plate on the lower back side of the weatherproof housing and, using it as a drill guide, drill four 0.375" diameter holes through the housing. Apply a small amount of silicon rubber seal within and around the holes on the INSIDE surface of the housing and then mount the plate in the orientation desired for the application using the provided 3/8”-16 x 1” hardware (bolt, flatwasher and nut). The blot head and washer shall be mounted from inside the housing as shown. Use silicon-seal to insure a weatherproof seal around the bolt head and washer.

4.Provide Signal/Power Cable Access Into the Housing

Depending on the desired orientation of the weatherproof housing, choose a satisfactory cable-entry point on or near the bottom of the housing and drill a 0.375" hole to accommodate the provided 1/4" rubber grommet. Use silicon-seal to weatherproof this cable-entry as needed.

5.Secure the Weatherproof Housing and Mounting Arm to the Plate Mounted on the Building Surface

The weatherproof housing can now be attached to the building using either length of Mounting Arm provided in the kit. It may be desirable to run the signal/power cable to the Base Station inside the Mounting Arm, entering and exiting the cable through the slots provided. Using the 5/16"-18 bolt and locking hex-nut provided, lock the Mounting Arm in place using the locating holes in the Mounting Plate tubes at each end. (Do not overtighten the hardware as this could distort the tubes, making future disassembly difficult.)
