This Callbox has all the functionality of our UHF 456 450-470Mhz Callbox XT Outdoor Intercom with Gate Relay plus it is equipped to use pre-recorded voice messages that notify other intercoms and two-way radios when specific events occur. These voice messages are recorded and stored on the Callbox, and automatically played back when the associated event occurs.

There can be a total of 5 event messages as follows:

  • Greeting Message: This message plays when a user presses the Talk button on the Callbox. You can use it to record instructions for the user to follow such as " Welcome to our facility. An attendant will be with you shortly. "
  • Identification (ID) Message: The ID message is transmitted automatically when the Talk button is first pressed. This message identifies which Callbox has been activated. A typical message might be, " South delivery entrance" or "Main Gate." The message will be retransmitted every time the Callbox is pressed until it is answered. If the Greeting Message is used, the ID message is transmitted after the greeting is played. The ID message can be periodically until the Callbox is answered. It is also sent ahead ahead of a Sensor Detect or Low Battery/Power Fail messages.
  • Low Battery/Power Fail Message: This message is automatically transmitted when low voltage is detected on the Callbox. The message may say something like " Power failure" or " Low Battery." The ID Message is sent immediately before this message.
  • Sensor Detect On Message:This message is automatically transmitted when a switch attached to the Sensor Input is closed. A typical message may be something like, " Door opened," "Motion detected," or " Vehicle present." The ID Message is sent immediately before this message. A typical message may be something like, " Main Gate," Vehicle present."
  • Sensor Detect Off Message: This message is automatically transmitted when a switch attached to the Sensor Input is opened. A typical message may be something like, " Door opened," "Motion detected ," or "Vehicle present." The ID Message is sent immediately before this message.
