GAI-Tronics’ RED ALERT® Hands-free WiFi VoIP Surface-mount Telephones are designed to provide direct pointto-point communications between personnel over an existing wireless local area network (WLAN), meeting IEEE 802.11 b/g standards. These telephones will operate from an external dc power source which is the only wiring required for operation.

In addition to providing standard telephone operation, RED ALERT® WiFi VoIP Telephones feature real-time alarm reporting that enables system supervisors to monitor the telephones’ activity and address caller needs or maintenance issues immediately. Also, four user-configurable inputs and two outputs (ideal for strobe activation) have been provided for customer use.

RED ALERT® Hands-free WiFi VoIP Telephones’ features make them ideal for use in any point-to-point communications application where an existing WLAN can be used for connection to a local VoIP PBX or server.

Typically installations locations include:

  • College Campuses
  • Parking Garages
  • Sports Arenas
  • Business / Industrial Parks
  • Factories

Embedded web pages held within the WiFi VoIP Telephone can be accessed over the network using a browser, such as Internet Explorer, to view, monitor, setup, and change settings within each unit.

GAI-Tronics’ RED ALERT® Hands-free WiFi VoIP Surfacemount Telephones are housed within a non-metallic or cast aluminum enclosure. Their bright, safety yellow color provides excellent visibility for telephone location and the rugged construction delivers a robust and weather-resistant solution for virtually any VoIP communication application.
