This wireless intercom can extend your two-way radio network across the world. It is intended for those organizations who have their own private, IP data network with the proper QoS mechanisms in place. If you are currently using Voice over IP, then chances are good you have most of what it takes. If this all sounds foreign to you, you may not be a candidate for this product, unless you have network people who will be handling the design and installation for you.
The VHF 25,000-Mile Intercom is based on our popular MURS or UHF Commercial Intercoms. It is available in either VHF or UHF frequencies. It has all the capabilities of our Commercial Intercoms, plus it has the ability to interface with a Radio Gateway or RoIP Router that transfers the transmissions over an IP network.
A built-in RJ-45 connector and Type 3 (or 5) E&M analog interface allows easy connection to the IP network using a RoIP router or radio gateway. When connected to the IP network via a router or RoIP gateway the 25,000-Mile Intercom enables compatible land mobile radios to communicate across the IP network to any other networked device (i.e. PC, laptop, IP phone, cell phone) including two-way radios regardless of make, model, frequency band or signaling format (equivalent hardware/software may be required at opposite end). This intercom can be programmed to work with virtually any brand of VHF or UHF business band radio.
For even greater talk range and/or increased penetration in and around buildings, the 25,000-Mile Intercom can even be programmed to communicate with a radio repeater.
Configuration of the 25,000-Mile Intercom is a simple process that consists configuring the type of E&M connection, either Type 3 or 5, and plugging it in to your gateway/router. The main detailed configuration is all done within the gateway/router. This is not something our support people can help you with since this is part of your data network and there are just too many variations of equipment. This why you will need skilled network technicians to install this equipment. We can help you with the two-way radio part and we can even program the 25,000-Mile Intercom to work with your existing radios if you have them.

Intercom Capabilities
The VHF 25,000-Mile Intercom communicates on all 5 channels of the MURS frequencies. MURS is short for Multi-Use Radio Service and is a newly created service by the FCC in the United States. It is a low power, short range service in the VHF (Very High Frequency) 150 MHz Citizens Band radio spectrum in which you do not need a license to operate a MURS station.
The 25,000-Mile Intercom has a small, rugged metal case and is designed for industrial applications. It is desk or wall-mountable with an optional wall-mount bracket, and has a range of up to 2 miles line of sight.
See the applications and other products available for MURS in the MURS Application Bulletin (requires the free Adobe PDF Reader to view and print).
| "We purchased the MURS 4 Mile Range and MURS Commercial Intercoms because one of our Preschool classrooms is far removed from the office – there was no way of communicating electronically/ rapidly which is of special concern in case of emergency. We decided to purchase the outdoor Callbox XT to put out on our playground.
The classroom piece of the intercom has saved much frustration and time simply by eliminating the need for a staff member to either leave her classroom to walk to the office or vice versa. Our office staff (one of whom is handicapped) LOVES them because they don’t have to get up and down repeatedly to deliver messages/ gather information, etcetera. It’s all done through the new intercoms. They provide peace of mind in case there is an emergency." -- Stephanie Molina, Southwest Child Care and Education Centers, Albuquerque, NM

This intercom will also work with our low-cost MURS Multi-Mile Intercom. Plus, it works with the MURS Callbox Outdoor Intercom and it can send a signal to the Callbox to unlock a gate or activate some other electrical device.
If you want to add a louder external speaker, you can plug an optional one into the speaker jack. You can also plug in an optional external microphone. If you want to use a headset, there is an optional headset that plugs into both the speaker and microphone jacks.
The 25,000-Mile Intercom includes an AC adapter for wall power, plus you have the option of powering it from a 12 volt DC car adapter and use it along with a magnetic mount antenna (you would need a wireless connection for the RJ-45 to do mobile applications).
The VHF 25,000-Mile Intercom also has a built-in NOAA Weather Radio feature so it can receive NOAA weather radio broadcasts or National Weather Services alerts for threatening weather. These features can be turned off or on via field programming.
See Figure 1 below for a description of the intercom controls and connectors.
As mentioned above, if you are already using two-way radios, this intercom can also be field-programmed to other VHF frequencies to match those radios. If you are using UHF radios contact us because we can offer you this same intercom in UHF at the same price.
