About Algo Communication Products:
The Visual Alerter can be used for visual indication of message waiting, ringing, telephone in use or caller in queue. Available in red, blue or green, the alerter can be located on the desktop, cubicle wall, above a computer monitor, or hard wired in a wall or ceiling mount application. The Visual alerter is plug and play compatible with Algo's Auxbox and with Nortel Networks' MEARI accessory for the M3900 series of Meridian 1 digital telephones for in-use indication.
