The PS 407 room and bathroom sub-control unit is an element of the SSP 4000D call signaling system and replaces the earlier version of the PS 405. It enables the transmission of paging and alarm signals from the sick room and bathroom in this room, or from an independent bathroom to the nursing station, and from there to medical rooms and apparatuses sound system.
In addition, they control signal lamps in the corridor and allow the deletion of all signals triggered from a given room. The PS 407 sub-control unit can control ordinary LS 43 three-color lamps or LS 144 four-color lamps. The fourth color – white – signals a call from the bathroom for the disabled.
Additionally, when the sub-control unit is set to work with a four-color lamp, it is possible to control an additional two-color directional lamp.
