MURS Basic Commercial Wireless Call Box

The MURS Basic Callbox works with our other MURS radios and it provides long range, 2-way voice communication from the fixed location of the Callbox to any of your other MURS intercom or handheld units. It has a range of up to one mile or more with an optional external antenna.

See the applications and other products available for MURS in the MURS Application Bulletin (requires the free Adobe PDF Reader to view and print).

This model is recommended for indoor use and in controlled environments with no public access. The MURS Basic Callbox does have a weather-resistant housing so it can be used in covered outdoor locations where direct impact from the weather is not prevalent.

If it is to be used outdoors it is imperative that the entire antenna connection be sealed with seal tape to provide proper operation and to prevent voiding the warranty. Seal tape can be purchased at most Industrial Supply Stores, Hardware and Home Center Stores, or Electronic Supply Stores (example: 3M Scotch 2228 Rubber Mastic Tape).

However, the heavy duty MURS Callbox XT Outdoor Intercom is recommended when the Callbox will be used in areas of public access and heavy weather conditions.

There is no need for extensive wiring, trenching, remodeling, or installing dedicated phone lines with expensive monthly fees since the MURS Basic Callbox is completely wireless.

For simple installation, the MURS Basic Callbox is designed to operate on 6 D-cell batteries (alkaline or Ni-Cad rechargeable). An optional external power supply is also available.

The MURS Basic Callbox has two modes of power consumption. In Automatic Turn-Off the unit turns itself off after a programmed amount of of inactivity (up to 4 minutes). It can only be turned on again by pressing its Call button on the Callbox.  In this mode it cannot receive calls from other intercom or handheld radio units. It can only make calls and then other units can respond.

In Normal mode, the unit does not turn itself off and the MURS Callbox can not only make calls, but receive them as well. This mode consumes the largest amount of power and should only be considered if an external source of power is available. If an external source of power is used, the internal batteries can be installed as a back-up against loss of power.

Since this callbox operates in the MURS frequencies, no FCC license is required.

This callbox can be mounted using four screws through its back or using the optional MURS Callbox Basic Mounting Bracket in Related Products and Accessories below.
