ALGO 1127 LED Visual Indicator – Blue

The Algo 1127 Visual Alerter is an attractive high-performing light that provides visual indication of telephone in-use, ringing, message waiting, and ACD caller in queue.

Available in three colors and featuring selectable flash patterns, the 1127 is perfect for office environments where it may sit on the desktop, mount to a wall or ceiling, or be located remotely. Constructed with 18 high-intensity LEDs, the 1127 provides a softly diffused light that is highly visible in all directions. Power supply is included.

Direct activation is by relay (dry contact) input or low voltage detection. Additional products may be required to provide compatible outputs driven by specific events in SIP, IP, analog, and Avaya or heritage Nortel environments.

Typical Applications:

  • Headset users (Receptionists, Agents)
  • Workers in cubicle environments
  • Hands-free call-in-progress “on air” notification
  • Notification to family for Telecommuters
  • Noisy environments
  • Noise-sensitive environments (Hospitals, Theaters, Churches)
