The Telephone Ring Initiated Beacons are designed for industrial and community welfare applications where a visual indication of a ringing telephone is required. Applications also include 'Emergency Evacuation' alarm and 'Colour Coded Personal Telephone' indication for use in factories where high ambient noise levels persist. The beacons are used in many applications with the GAI-Tronics products and systems. These beacons are compatible with GAI-Tronics’ analogue telephones.
