Stop worrying about the expensive and time-consuming process of running wires through concrete or asphalt surfaces. You will save on both initial installation fees and future repair costs but avoid underground wiring maintenance problems and unexpected damage to electrical connections. The MURS Callbox XT provides a cost-effective wireless communication solution that operates over long distances without requiring trenching, permits or rewiring.
The MURS Callbox XT Kit includes:
- One MURS Callbox XT Outdoor Wireless Intercom
- One MURS Commercial Handheld 2-Way Radio
When visitors arrive, they simply press the button on the callbox to send an alert tone indoors. By holding the button, they can speak directly with the inside station. Both units work as a simple press-to-talk, release-to-listen system, ensuring quick, clear responses., enabling clear, two-way communication over distances of up to a mile (with optional external antenna). Ideal for any outdoor site, the MURS system is the perfect communication tool for remote locations, ensuring safety and accessibility without the need for wiring or internet.
Key Benefits of the MURS Callbox XT:
- Long-Range, 2-Way Voice Communication: Connects the callbox to any compatible MURS intercom units up to a mile away.
- Battery and Power Flexibility: Operates on 6 D-cell batteries or an external 12 volt DC power source, with Auto Turnoff features to conserve battery.
- Remote Activation and Control: The 1-Amp switch output functions to operate gates, control lights, trigger alarms, and manage various devices. Because this switch is programmable users can customize it for numerous on/off purposes.
- Security and Durability: The unit combines a weather-resistant fiberglass enclosure with a stainless steel faceplate to create a tamper-resistant device built for harsh outdoor environments.
- No FCC License Required!: Operating with the five MURS frequencies requires no licensing.
In Normal mode (not battery saving Auto-turnoff mode), the MURS Callbox remains active, allowing it to both send and receive calls. This is perfect for high-traffic areas where constant connectivity is essential, such as airports, hotels, gated entrances, parking lots, and more.
Advanced Features for Versatile Applications:
- Sensor Input for Enhanced Detection: Integrates with sensors to detect motion, gate entry, tampering, or vehicle presence, triggering an alert when needed.
- Listen-In Capability: Allows you to monitor the surroundings near the callbox for up to 30 seconds with a unique 2-Tone code.
- Customizable Broadcast Messages: Send pre-recorded messages for greetings, alerts, and status updates, such as low battery or power failure, directly to connected radios or via the callbox speaker.
Operating on MURS frequencies means you can bypass FCC licensing requirements while the unit arrives ready for quick setup out of the box. The MURS Callbox XT provides strong communication capabilities that adjust well to the changing requirements of outdoor spaces.
Perfect For: The MURS Callbox XT serves construction sites, hotels, parking lots, gated entrances, campuses, hospitals, warehouses, farms and any other location which demands reliable wireless communication.

Switch Output Programming:
This Callbox has a switch output that can be used to open or close a gate, turn on a light, sound an alarm, or any application where remote control of an On/Off switch is required. The switch can be programmed to operate in several ways:
- On/Off Code: The switch will close when a preprogrammed code is received, and open when it is received again. The switch will also open by itself when the Callbox's preprogrammed Automatic Turn Off feature is activated.
- Switch On When Called: The switch closes when the callbox first receives the call and it remains on until its Talk button is pressed, or a programmable timer expires (1-255 seconds).
- Switch On When Callbox In Use: The switch will close when the Callbox first sends or receives a call and remains closed until a preprogrammed timer expires.
- Switch On When Active Includes Turn-Off Code: Switch closes when the Callbox sends or receives a call with the added ability to open the switch when the Callbox receives a preprogrammed code.
- Momentary Close: Switch will close for 1-255 seconds when a preprogrammed code is received.
- Alternate Open and Close: Switch will toggle between open and closed when it receives a preprogrammed code. The Callbox transmits a single beep when open and a double beep when closed.
This unit comes preprogrammed to MURS Channel 1 with an Interference Eliminator code of 01 which matches our other MURS Radios. Unless you need other features activated, you should not have to program this unit, but it is field programmable.
Reviews:
"We are utilizing the call boxes at three vehicle entry gates onto the property. Two of the locations are equipped with badge readers that operate the gate. One of the locations is a Visitors entrance where the person entering interacts with our Security via the call box.
Our old system was done with all underground wiring and we were experiencing many problems with broken underground conduit. The wireless solution was the way to go for us. The system was very easy to install especially with the additional functionality that I wanted. The technical customer support was excellent. They seemed to care a great deal about my project being successful which left me with the confidence of knowing that If I ran into any problems that all I needed to do was pick up the phone. We have not experienced any problems with our system."

"We use the callbox to talk to visitors and open the entrance gate from the office and portable radios (walkie-talkies). We can talk to visitors wirelessly and open the gate wirelessly from the office or the portable radios. Personnel can be anywhere on our 40-acre site and still communicate with the gate and open it. Physical installation was simple and the instructions are good. Technical support is very good. The programming is a little tricky until you understand how to do it."
John Danna, MOTCO Trust Group, La Marque, TX [IntercomsOnline.com: the units come preprogrammed and only need programming for custom applications, and we can do that for you if you like]
"We use your callbox on the outside door of our plant so truck drivers can call in and identify themselves and we can then let them in remotely through a security door. Everything about the callbox works for our application, but we especially like the how we can use a wireless handheld unit to remotely manage the entrance when we have to leave the office to go to other parts of the plant."
