Description

The TD-HL series handset intercoms are designed for applications where visual indication of an incoming call is required. The red LED mounted on the top front of the unit lights whenever a station receives a call. The TONE OFF switch at the bottom allows the user to turn the standard call tone on or off at any time. The LED will light regardless of the switch position. Ideal for applications where silent signaling is required, such as radio stations or sound booths.
