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
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.
