| Okay, I don't have pics, and only have a limited description. I am trying to identify a lighting system. Here's what I know about it:
Each room has individual control of its light, using a spring-return-to-center wall switch, same size and shape as a normal light switch, except it springs back to the middle when you let go. The switches themselves are made by General Electric, but I don't know if they were purchased as part of the system or if they're just generic switches.
There is a central control panel that handles an average of 24 rooms (there are several zones of these, some have more or less, but the one I directly saw had 24). This panel has rectangular white buttons in pairs - one on top one on bottom for each light. in most/many cases, the top button has a red LED in the center of it. This panel I saw was built in four sections - eight rooms were served per section. There is one single button, which takes up the sapce of a full pair, on the very right of each section. The bottom section contained only two sets of buttons. They were labeled "MASTERS", but the labeling consisted of DYMO labels added by the current occupants of the building, so they probably won't help identify it.
The panel itself is hinged, and locks. The external part of the latch is a rectangle handle with a keyhole/lockcylinder in the center of it. One pulls on this to open the panel.
Using these pairs of buttons and the "MASTERS", a person at this panel can set each room to be forced on, forced off, or controlled by the switch in the room.
Everything is handled by relays which latch - in the event of a power failure, when the power is restored, everything "remembers" what state it was in before the failure.
This system was installed in 1989, and thus must have been on the market near that time.
There are no manufacturer's logos on the panel.
I would appreciate any information anybody might come up with that would help in identifying this system. |
