This Wireless PA System is extremely flexible and works with MURS, UHF. VHF, GRMS, and FRS radios. You can use your existing radios or new ones.
Part Number: RT1118

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

You'll use this solution where hardwired installation is simply impossible, too expensive, or the installation is only temporary. The 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 a dedicated communications channel between the 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.

To widen the coverage area, you can install up to two loudspeakers on a single Wireless PA receiver. As a general rule each of the speakers will cover up to 7500 feet, but we have seen greater coverage in areas that are not excessively loud. 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 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.

The 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 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.

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 Wireless PA receiver and antenna that can be used for outdoor applications.

In heavily populated areas where other 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.

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

The system comes pre-programmed to Channel 2 of the MURS frequencies, but it can be programmed to match almost any two-way radio. When you receive the system make sure your other radios are set to channel 2.
