| |  MURS 4-Mile Range Intercom: Indoor Call Box
Special Shipping Note: This item is built to order and generally ships in 2-3 weeks.
This indoor intercom call box is best suited for large work locations where users do not have the option to carry around radios or where you may only need a simple intercom to call a main station. Great for emergency communication, as well as everyday use, the long range of this system makes it a good choice for a variety of environments. This system is ideal for communication on construction sites, business lots, golf courses, hotels/motels, campuses, hospitals, farms, and warehouses.
Although this intercom is not weatherproof, it can be used outside in a well-covered area. It is recommended that the entire antenna connection be protected with sealing tape. This will help waterproof the unit, and keep exposure from voiding the manufacturer’s warranty. Sealing tape can be found at most hardware or electrical supply stores.
This system uses the MURS (Multi-Use Radio Service) wireless frequencies that results in an amazing communication range of up to four miles!* Superb wireless communication between remote locations is now possible!
The indoor intercom call box runs on 6 "D" size batteries. Alternatively, it can be plugged in using a 12V power adapter (not included). The choice is yours!
This system has two communication modes. The first is an energy saver mode that only activates the intercom when someone makes a call by pressing the talk button. In this mode, the unit will turn itself off after a programmed amount of inactivity (up to 4 minutes). The second mode allows other MURS intercoms to communicate with the call box without this box initiating the communication. The second mode does use more power so it is suggested that you connect the call box directly to a power source.
Our call box is fully compatible with all of our MURS radios, including our base stations and hand-held radio walkie-talkies. When a visitor presses the "talk" button, all intercom stations on the same channel are paged and any station can respond.
Please note: The indoor call box cannot be used by itself, but is sold separately as one single unit. It must be used in conjunction with either our base stations or hand-held radio walkie-talkies. We do sell individual intercom bases for each of these systems in the drop-down menu above.
Product note: This item is not pre-programmed for our MURS Base Stations or MURS Hand-held Radios. Although they may operate on channel 4 or 5, you may need to program the units together upon arrival. This item is pre-programmed for our Commercial Base Stations and Commercial Hand-held Radios. You may purchase either radio separately by visiting their pages.
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.
* Although line of site 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.
