NC150N Series Audio-Visual Nurse-Call System
The Alpha Communications® / TekTone NC150N series audio-visual nurse-call system is designed for health-care applications where voice communication and visual indication is required. The NC150N system can support only a single master station per system. 

When a remote station is activated, the NC150N annunciator will sound an electronic tone and will light, indicating the location of the call. The tone signal can be silenced at the master station (and/or at the optional LI150B remote duty station(s) for non-emergency calls). The individual switch/light will remain lighted until the remote station is reset at the point of origination, or when answered by voice from the master station (for remotes with voice capability only).

The NC150N master annunciator is modular and can be flush, surface or desk mounted, and is available in any size, in multiples of four (4) lights/switches. The NC150N features built-in tone signal, and tone silence button and light. 'TEST' buttons are used on each annunciator lamp module for lamp testing. A press-to-talk button enables the NC150N master to speak with any voice type remote station. Each NC150N master has a built-in amplifier with voice volume controls. An optional model TA150N handset module, can be installed onto any master station, for private voice communication, or for very noisy environments.
