More about the 4 Mile PA System

Here is the perfect solution for anyone needing a public announcement (PA) system, but who does not want to deal with wiring or electricians. Use several of these PA systems around different areas to send out a general announcement or set them up to contact a specific area. At full volume, the speaker can be heard up to 95 dB over 50 ft. away! You can also adjust the volume to accommodate hallways, offices, or smaller warehouses.

This PA horn is ideal for use inside a building, such as hotels/motels, receiving docks, warehouses or anywhere else you may need a bulletin or alert system. Two PA horns can be used on one receiver to cover a large area or two directions. You can add an additional PA horn using the drop-down menu above.

This system uses MURS (Multi-Use Radio Service) wireless frequencies, resulting in an amazing communication range of up to four miles!* To help control feedback from the sending radio, you can program the PA system to delay sending the message for up to 20 seconds. This setup is ideal for people who are using the hand-held radio walkie-talkies in direct line with the PA horn. In addition to broadcasting your announcements, this PA system can be used to receive and broadcast local NOAA weather radio emergency notifications from the National Weather Service. Our MURS wireless PA system is fully compatible with all of our MURS radios, including our base stations and hand-held radio walkie-talkies.

Please note: The MURS wireless PA system is sold separately as one single unit but cannot be used by itself. It must be used in conjunction with either our base stations or hand-held radio walkie-talkies. Authorized by the FCC, MURS is a license-free service that allows the user to transmit voice and data. MURS also allows a maximum of 2 watts of output power which means greater range than other license-free radio services.

*Please Note: Although line-of-sight is not required, the maximum range is based on optimal conditions with minimal interference. Wireless range is affected by objects such as walls, trees, etc. Actual range may vary, depending on environment.
