Put Long-Range Wireless Communication Anywhere You Need It.
Require dependable wireless connectivity in remote locations immediately? This Wireless Callbox is the ideal solution. The compact weatherproof unit operates without the need for expensive trenching or complicated wiring systems. Users can install the device through straightforward mounting and activation regardless of whether it uses external power sources or long-lasting alkaline batteries. Use handheld radios or base stations to communicate across distances up to one mile which works well for isolated locations and expansive properties.
The Wireless Callbox extends beyond basic communication functions because it enables multiple control features. Activate other devices by triggering lights or unlocking gates through this unit's built-in relay switch. Certain radios have pre-set buttons that provide users with fast and secure remote access. This product remains easy to operate and tamper-resistant while providing dependable service under extreme conditions because of its sturdy design.
The callbox enables pre-recorded message broadcasting and low battery notifications while ensuring you stay connected and maintain control. This callbox simplifies operations by allowing staff delivery notifications, remote entrance management and communication in difficult environments without any wiring requirements.

Stay connected with the Wireless Callbox and skip the hassle of wiring. Just mount it, power it up, and you're ready to go



Programmable Relay Switch
The call box has five pre-recorded factory messages that can be transmitted to receiving radios or played on the speaker when the Push-To-Talk button is pressed, batteries are dying, 12 volt power is lost, or a sensor triggered:
- Switch on when called - Switch closes (turn on strobe etc.) when the callbox first receives a call. Switch opens as soon as the PTT button is pressed, or if the callbox has not been used longer than its reset time.
- Switch on when active - Switch is closed (turn on strobe etc.) as long as the callbox is in use. Switch opens when the callbox has not been used (transmit or receive) longer than it's reset time.
- Switch is closed (turn on strobe etc.) - When the callbox receives or transmits a message until a 2-Tone code is sent from a programmed button on a radio.
- Switch momentary - Switch is closed for 1 second when the correct 2-tone code is received. Time can be extended up to 255 seconds
- Switch toggle - Switch alternately closes and opens with the correct 2-tone code is received.
Recorded Message Broadcast
This call box also has five factory pre-recorded messages that can be transmitted to receiving radios or played on the speaker when the Push-To-Talk button is pressed:
- Voice Alert (4 seconds max) - Message is transmitted when the PTT button is first pressed
- Greeting Message (12 seconds max) - Message plays on speaker when PTT button is first pressed
- Sensor Detect On (4 seconds max) - Message is transmitted when Sensor input is closed
- Sensor Detect Off (4 seconds max) - Message is transmitted when Sensor input is opened
- Low Battery (4 seconds max) - Message is transmitted when low battery voltage is detected
- Power Fail (4 seconds max) - Message is transmitted when a +12VDC power fail is detected
Installation Made Easy
This device includes a built-in antenna so you don't need to add an external one. If you require enhanced performance by overcoming obstacles or expanding your range you can obtain an optional external antenna adapter from Related Items which lets you position a higher antenna.
Our callboxes come pre-programmed to Channel 1 on the FCC license-free MURS frequencies, so no additional programming is necessary. They are fully compatible with our other pre-programmed MURS radios for seamless communication.
For installation, the unit includes two mounting brackets for flat surfaces, and for pole mounting, an optional gooseneck pedestal pole bracket is available. To ensure security, the callbox is sealed with four Torx screws, and we provide a Torx bit for easy setup.
How it Works
When a visitor presses the call button, a
warbling tone is transmitted to all two-way radios or base station
intercoms tuned to the same channel. If the unit is operating in
battery-powered mode, it will automatically activate to allow two-way
communication. After a period of inactivity, the callbox returns to
sleep mode and cannot be contacted again until the button is pressed by
another visitor. For continuous operation in full intercom mode—where
the unit remains active at all times—an optional cable and a 12-volt
power supply are required (see Related Items). If you are using the
internal relay for door or gate opening, you activate it by pressing a
button on the inside base station intercom or handheld radio.

- Volume Level. Field programmable or PC programmable to 5 “ 100% volume level
- This callbox is equipped to use pre-recorded voice messages that notify radio system users when specific events occur. These unique voice messages are recorded and stored on the callbox, and automatically played back when the associated event occurs. It supports 5 different message events and comes from the factory with no messages recorded
- Battery Powered. Can be powered by 3 Alkaline D-cell batteries for 700mW transmit power. D-cell batteries can operate the radio for up to one year or 7,000 transmissions
- External Power +12 VDC Capable. Can be powered by an external +12 VDC source. This method of powering the callbox allows the radio to remain ON at all times, like an intercom. Automatic Turn Off must be DISABLED
- Low Battery Alert. The callbox will transmit an Alert Tone at the end of each transmission when the batteries approach end-of-life. This allows sufficient time for you to replace the batteries and assure uninterrupted service. Can also transmit a recorded Low Battery voice message
- +12 VDC Power Fail Alert. This feature can be enabled via Field or PC programming. The callbox will transmit an Alert Tone if it detects loss of +12 VDC power. The radio automatically continues to transmit an Alert Tone once every hour (unless programmed for Automatic Turn Off) until +12 VDC is restored or the batteries are depleted. Can also transmit a recorded Power Fail voice message
- High/Low Power Output. When powered by External +12VDC the callboxes can be Field programmed for High or Low transmitter power output. When battery power the callbox operates in Low power mode exclusively "Automatic Turn-Off" or "Intercom" Operation. The Callbox can operate in the standard "Automatic Turn-Off" mode (Factory Default), where the radio is normally OFF until the Call Button is pressed, or can be Field or PC programmed for "Intercom" operation where the radio is always ON. See "External Power +12 VDC Capable" feature above.
