Busylight Combi presence indicator

The Plenom 15301 Busylight Combi is a visual call alert and presence indicator for desk phones and headsets. It uses red and blue bulbs to show on-call status and availability at a glance. The device helps reduce interruptions in shared or open-plan offices. It is designed for professionals who need a clear, external status signal.

Suits open-plan and shared desks

This indicator suits users who want colleagues to see their call state without software-only presence. It works with supported desk phones and headsets for a hardware status light. Buyers who need audio alerts, multi-colour customisation beyond red and blue, or integration with unsupported UC platforms should look at something else.

Visual alarm with red and blue bulbs

The single specification that decides fit is the visual alarm type using a red bulb and a blue bulb. If your workflow requires a hardware light that shows busy or available through these two colours, this unit matches that need. If you require a different alert method or colour scheme, this is not the right part.

Questions about this item

Does the 15301 Busylight Combi need a separate power supply to operate with my desk phone?

The unit draws power from the connected desk phone or headset, so no extra power adapter is required.

Will the visual indicator still show status if I keep using my older analogue headset?

Yes, the Busylight Combi works with both modern and legacy headsets that present a standard call-control interface.

How can I confirm the red and blue bulbs are signalling correctly after I plug it in?

Make or receive a test call; the red bulb should light during the call and the blue bulb should show your presence state when idle.
