NIR-LB
The Aiphone NIR-LB (also referenced as NI-LB) is a flush-mount ceiling speaker designed for use with the NI-SB ceiling microphone in NIM-Series nurse call systems, enabling hands-free audio announcements and two-way communication in multi-bed patient rooms.
It receives voice from master stations and works in tandem with the NI-SB microphone (mounted 50cm away to prevent feedback) for room-wide paging or staff responses.Key Specifications
