Telephone Visual In-Use (Off-Hook) Indication

Visual indication of a telephone's in-use status, through the use of a highly visible light, is important in order to prevent disruptions to important calls and to minimize the inadvertent transmission of background conversations. For people who work in close contact with co-workers and frequently use the telephone, a bright in-use light can ensure a more effective and secure telephone environment. 

Visual in-use indication is particularly important for people who regularly use a headset or a hands-free model. This is because they can often appear to others as though they are not on a telephone call simply because they are not physically holding a telephone handset to their head. This can lead to unwanted interruptions as well as the transmission of inappropriate or confidential background conversations. An in-use light elegantly solves this problem.

Algo offers a number of solutions for Visual In-Use that are compatible with telephone technologies that include SIP, analog, Nortel, and Meridian Digital Centrex. In most cases, these solutions are made up of two parts: the "visual" part (the lights), and the "connecting" part (the interface device that allows you to connect to various telephone technologies).

Algo offers two basic indicator light options: the Algo 1127P Visual Alerter and the Algo 1126 Strobe Light, both of which can be used interchangeably depending on the application.
