When you need a call station for quick communication between two parties, the economical CALL24 M-Series callbox is the answer. The single push-button-simplicity affords instant communication that improves and assists guest services and employee productivity.

The CALL24 M-Series Radio Callbox is perfect for resorts, manufacturing, construction, perimeter gates, mining, trucking, warehousing, schools, marinas, storage – or virtually any location that needs improved customer service.

Free yourself from skyrocketing construction costs, the risks, and the disruptive mess created by boring and trenching lines to a wired communication station. CALL24’s all-weather M-Series callbox is wireless with no recurring monthly fees.

Want to place a callbox hundreds of yards from the nearest power and phone lines? No problem. Want to relocate a callbox in three years? It’s simple and inexpensive. CALL24’s long-range wireless callbox incorporates radio technology that is used by industry, hospitality, and public safety worldwide.

In addition to the benefits of being a wireless solution, CALL24’s M-Series callbox comes standard with reliable battery backup power. While a single battery charge can last up to several months, supply volt recharging is necessary to allow extended 24/7 operation without removing and replacing batteries.

CALL24’s Suncharge™ system offers a solar-powered, totally free-standing callbox solution. Or if the standard 110-120 VAC current is available, our Starcharge™ system keeps your call box fully charged.

Worried about losing communication with your callbox during a power outage? Don’t fret…CALL24’s long-lasting batteries are not susceptible to temporary outages.

Because CALL24 is a radio-centric solution, your response to any call is as simple as placing a portable radio in the hands of the right responder. If you have a callbox located at a remote gate, the caller may be communicating with a security guard to gain access to the facility.

For instance: truck ready to be loaded? A gate-card reader has malfunctioned? Golf-course first tee?

Each long-range M-Series callbox is delivered completely programmed for seamless integration into your digital or analog radio system.

Unlike wired callbox systems, CALL24 helps you avoid the expense or disruption of boring and trenching to each callbox. Just pick a spot with clear sun exposure or near a local 115vAC power source. No worries about communication lines because CALL24’s callbox is wireless.

Not only can you install the radio callbox virtually anywhere, but you can also use one of our bronze anchor mounted aluminum poles, or install the M-Series to a building or light pole.

Do you have a restricted area where service providers, employees, or guests that need periodic access? Don’t waste precious human resources manning a remote gate. There is no need to walk or drive all the way there to let someone in. Simply pick up your radio and key in a code to remotely open the gate or release an electronic lock.
