Description
 

The Two-Way Radio UHF Wireless PA Interface receiver allows someone on a two-way radio or base station intercom to send an announcement to all the wired speakers in a PA/Intercom system. The Wireless PA Interface receiver can be connected to an existing wired system and it can receive transmissions from up to a mile away. Radio range can be extended with the use of an external antenna.UHF Wireless PA System for Two Way Radios

This device can also be used in conjunction with the UHF Wireless PA System on the same frequencies.The difference between the UHF Wireless PA Interface and the UHF Wireless PA System is that the Wireless PA Interface does not have a built-in audio amplifier. The built-in audio amplifier allows the UHF Wireless PA System receiver to drive up to 2 PA horn speakers as a stand alone system.
The UHF Wireless PA Interface receiver is designed to be connected to an existing PA/intercom system with its own PA amplifier and wired speakers. The UHF Wireless PA Interface receiver also does not include a back-up battery since it is merely a component of a larger system usually powered by AC and its own battery back-up system.

The UHF Wireless PA Interface will block out any signals that it receives that are not programmed with one of the selective signaling formats it uses. It can be paged with 2-way radios programmed for Quiet Call (CTCSS), Digital Quiet Call (DCS), 2-Tone Paging, or Selcall paging formats. Each format offers a unique method of paging the receiver and they ensure that not just anyone can use your PA system.

The UHF Wireless PA Interface connects to the Aux Input of the PA system via RCA Phono Cable if it is located within six feet of the wireless PA system. Or it connects via the 600 ohm balanced MIC input on the PA system the distance it is further than 6 feet. A typical balanced cable contains two identical wires, which are twisted together and then wrapped with a third conductor (foil or braid) that acts as a shield.

Once installed, operating the UHF Wireless PA Interface requires no human contact. Portable, base station or mobile two-way radios can deliver voice messages directly to a PA system with a simple press of the Push-to-Talk button for either live or recorded playback.

The MURS Wireless PA Interface can be set to provide a relay switch closure any time a valid message is received. The relay can be connected to a PA amplifier "Priority", "Override", or "Emergency" Input to activate the wired PA system. The relay can be set to normally open or normally closed.

UHF Wireless PA Interface Connections

The UHF Wireless PA Interface can be programmed to match other UHF radios on the frequencies below without aid of an optional programming kit.

Features
  • Designed to be connected to an existing PA/intercom system with its own PA amplifier and wired speakers
  • Does not include a back-up battery since it is merely a component of a larger system usually powered by AC and its own battery back-up system.
  • Available in VHF (150-162 MHz) and UHF (450-470MHz) frequency bands. Provides compatibility with business band 2-way radios, License-FREE VHF business band radios (MURS), Family Radio Service and GMRS radios.
  • Provides interconnection to the Public Address amplifier through a high impedance, unbalanced AUX input OR a 600Ω, balanced MIC input. Allows personnel to remain mobile while providing access via 2-way radio access to existing PA speakers located throughout the facility.
  • If the AUX input of the PA/Intercom amplifier is already used (ie: stereo tuner for background music) the interface is installed in-between the audio source (stereo tuner) and the PA/Intercom amplifier.
  • When the PA interface receives a message the audio source is interrupted and the received message is sent to the PA/Intercom amplifier instead.
  • "Record and Play" allows use of radios in close proximity to PA speakers without feedback. The PA interface records/buffers received messages up to 30 seconds in length, then plays them over the PA immediately after releasing the PTT button on the radio.
  • Easy "Plug and Play" installation.
  • Programmable volume control adjusts audio output level 5-99%. Allows custom adjustment for most applications.
  • Selective signaling includes QC, DQC, Selcall, 2-Tone to provide an added layer of access control to the PA system.
  • Pre-announce tone (similar to existing PA systems) with programmable on/off and volume level.
  • NOAA Weather Alert (VHF only).
  • Field or PC programmable to frequencies within the respective band (i.e. 150-165 MHz, 450-470 MHz).
  • For indoor use ONLY.
