Description
Give hearing-impaired employees, call center staff, and open-office workers a clear visual signal for ringing, on-hook/off-hook status, and message waiting — the Viking LPL-1 is a telephone line powered LED visual ring indicator that requires no external power supply and is visible up to 100 feet away.
The LPL-1 monitors analog phone lines or PABX station ports and displays three distinct states: "Ringing" when the phone is being called, "On-the-Phone" when a call is active, and "Message Waiting" for voicemail notification. Telephone line powered with no batteries or power adapter required, it installs in-line with any analog phone. Ideal for hearing-impaired locations, call centers, telemarketing offices, office cubicles, and purchasing departments where visual call status confirmation improves workflow.
Our Expert Take: The LPL-1 is a simple, low-cost ADA accommodation and productivity tool for any environment where audible ringing can be missed — open offices, loud workspaces, and cubicle farms where phones are shared or not easily heard. The 100-foot LED visibility means a single unit can serve a wide workspace.
