MURS Wireless PA System

The MURS Wireless PA (Public Address) is a radio receiver that allows you to use your base station intercom or mobile 2-way radio to deliver voice messages directly to an attached PA speaker up to 2 miles away.

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

You’ll use this solution where hardwired installation is simply impossible, too expensive, or temporary. The MURS Wireless Public Address receiver and PA speaker are designed for quick setup and usage to deliver your message to a large campus or property. You can use this device with our other MURS products since it uses the same unlicensed frequencies. When used with the MURS Commercial Intercom or the MURS J-V110 Two-Way Radio you can program coding that will restrict access to the MURS Wireless PA to only those radios that have a proper code programmed. This ensures that only authorized people have access to the PA system.

You can use a dedicated communications channel between the MURS Wireless PA and the radios or intercoms that are contacting it, which enables you to use your radios or intercoms for normal communications without broadcasting over the PA system.

You can do zone paging, or paging in more than one location, by installing multiple MURS Wireless PA receivers and setting a unique paging code for each one. All the receivers can operate on the same channel with use of this code. An “All Call” code can also be programmed so all zones can be paged at once. The feature requires an optional DTMF tone decoder to be installed in the MURS Wireless PA.

To widen the coverage area, you can install up to two loudspeakers on a single MURS Wireless PA receiver. A single speaker will cover up to 100 feet. Each speaker comes with a 25 ft. cable. Cables can be extended by using standard RCA phono cables and couplers.

When 2-way radios are used in the same area as the MURS Wireless Public Address speaker, feedback may result that can render the system unusable. For those applications the receiver can be programmed to record the incoming messages and play them back over the speaker when the talk button is released on the 2-way radio. Recorded messages are limited to a maximum of 20 seconds.

You can also enable the MURS Wireless PA to receive local NOAA weather radio emergency broadcasts from the National Weather Service and play them over the loudspeaker. This will keep everyone aware of severe weather approaching. This feature requires setting the unit to your local weather alert frequency.

The MURS Wireless PA receiver requires 110VAC power. It also comes equipped with an emergency backup battery that can temporarily power the radio if primary power is interrupted. The rechargeable battery backup is not intended to operate the radio for an extended period of time. A heavy duty external +12 VDC battery can also be used to power the receiver and the receiver can be configured for powered operation to maximize battery life. A solar panel kit can be used to power the MURS Wireless PA receiver without the need for a power supply in locations where AC power is not available.

An optional magnet-mount external antenna can be installed at a higher elevation to increase receiving range. This antenna has a 25 ft. cable to allow optimum antenna location.

The radio receiver box is not waterproof so it should be located inside out of the elements. There is an available weatherproof, fiberglass reinforced polyester enclosure designed to house the MURS Wireless PA receiver and antenna that can be used for temporary outdoor applications.

In heavily populated areas where other MURS radios may be in use, this unit has the "2-Tone Decode" capability that enables it to only receive pages from other radios with the "2-Tone Encode" feature. The MURS Commercial Intercom and the MURS J-V110 Two-Way Radio have this feature.

Once installed, operating the MURS Wireless Public Address radio receiver requires no human contact. The MURS Wireless PA reduces installation costs that would otherwise be incurred by using a wireless PA system.
