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

• Internal Antenna, Tough, Machined Aluminum PTT Button Long-Life, Tamper and Vandal-Resistant
• Built-In Relay Control Allows Long-Range, Remote Control Of Gates Or Doors. SPDT, 3A, 125VAC/30VDC – Normally Open or Normally Closed (NO Default). Modes of Operation: Momentary or Toggle, On/Off
  
• Relay can be used to activate a strobe light when someone presses the call button or when Callbox receives a call (visual indication of a call).
• Sensor input responds to an Open or Closed switch. Callbox will send either an alarm tone or a recordable voice message when optional switch/sensor detects a change.
• Aux Sensor Monitoring Input : Optional sensors used to detect motion, gate movement, vandal/tamper or vehicle presence can be connected to the callbox using the sensor input.
  
• Standard Flange Mount Hole Pattern Easy Installation. Optional Mounting Brackets Available
• Volume Level. Field programmable or PC programmable to 20 to 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
• 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.
