Wireless Callbox Brochure

This heavy duty outdoor intercom is designed for construction sites, golf courses, hotels/motels, airport parking lots, gated entrances, manufacturing, college campuses, hospitals, receiving docks, amusement parks, resorts, locked entrances, farms, ranches, warehouses, campgrounds, parking lots, delivery doors, and any other application that needs two way communication for safety or convenience.

There is no need for extensive wiring, trenching, remodeling, or installing dedicated phone lines with expensive monthly fees since the Callbox is completely wireless.

For simple installation, the Callbox is designed to operate on 6 D-cell batteries (alkaline or Ni-Cad rechargeable). An optional external power supply is also available.

The Callbox has two modes of power consumption. In Automatic Turn-Off the unit turns itself off after a programmed amount of inactivity (up to 4 minutes). It can only be turned on again by pressing its Call button on the Callbox. In this mode it cannot receive calls from other intercom or handheld radio units. It can only make calls and then other units can respond.

In Normal mode, the unit does not turn itself off and the Callbox can not only make calls, but receive them as well. This mode consumes the largest amount of power and should only be considered if an external source of power is available. If an external source of power is used, the internal batteries can be installed as a back-up against loss of

If you use the CallBox Outdoor Intercom with Gate Relay along with a radio that can send a 2-Tone encode signal then the Callbox can be used to remotely control gates or magnetic door locks. The Callbox has a single 1-Amp switch output that can be activated when the Callbox receives a unique 2-Tone encode signal that the radio sends.

The Callbox with Gate Relay can also operate as a motion, gate entry, tamper or vehicle detection device. It will send a tone alert when optional switch/sensor status changes. The Callbox will send a warning tone when a change in the Sensor Input is detected. The Sensor Input will respond to an OPEN or CLOSED switch.

The Callbox is housed in a fiberglass enclosure with a stainless steel faceplate that includes tamper-resistant fasteners and a concealed antenna making it perfect to withstand harsh elements.

The Federal Communications Commission (FCC) requires the owners of radios operating on these frequencies to obtain a station license before using them.

If you are using this system with your existing UHF two-way radios, make sure you enter in the Notes field of the order the frequencies that you want the Callbox to use so we can program it for you. Include any privacy codes and the 2-Tone encode signal you are using. You must also include the Business Band Radio Programming option in your order to have us program the Callbox, or you can program it yourself using the enclosed user guide.
