The PFS switching unit for building automation is available in 8, 12 or 16 channel formats and is designed for controlling dimmable fluorescent ballasts, curtain/drape/window shade motors and other motorized equipment such as swimming pool covers and sky lights.
The PFS building automation and lighting control system is designed to control dimming/ switching for:
- convention centers

Building automation and lighting control
The unit has motor interlocking, for operating dual-motor curtain and drapes.
Inputs and outputs are easily configurable according to function, and can be switched independently, or as part of a scene, an event or macro.
Adjustable voltage level triggering, which switches fluorescent ballasts ON or OFF at a pre-set point in the dimming curve, can be used for switching the ballast’s power rail, in conjunction with the integral 1-10v converter card.
It can be configured to operate low level control loads such as intruder/fire alarms and AV equipment. Easily configurable features include comparison-switching, where switching only takes place when a logic level input from AV/air conditioning equipment doesn’t match the desired status.
The output can mimic a switch-press that requires a pulse contact closure of variable duration.
