The SF125 Duty Station annunciates calls both audibly and visually via 4 colored LEDs and a tone speaker. The various call priorities will be indicated by the LEDs and the highest level call will be annunciated by time. Watched zones are programmable via the LS450 Config Tool.
The SF125 Duty Station connects via the LI122UN Room Controller with Dome Light or the PM120 Room Controller, using 2 of the 6 connection points. Each NC120 Central Equipment Module supports up to 24 duty stations (6 duty stations per run) depending on power restrictions.
