Not only can you control the security gate, you can also talk to the people at the gate before you let them in.Security gate control

You can get a heavy duty outdoor wireless intercom or Callbox that you install at the gate. When people press its button it sounds a tone on a handheld two-way radio or wireless base station intercom. You can then press a button that activates a relay, which opens the gate or performs some other action. These Callboxes can work up to a mile or more away.

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.

The MURS Callbox with Gate Relay also has a Sensor Input that allows it to 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.

You can get these wireless outdoor intercoms that work in FCC licensed UHF or VHF frequencies or on the unlicensed MURS frequencies. See the free book called Two-Way Radio Success: How to Choose Two-Way Radios, Commercial Intercoms, and Other Wireless Communication Devices for Your Business for more information about MURS and these security gate control wireless intercoms.
