4.2 Collage Architectural Connections
There are three link connections available for the Collage Architectural controls. The system follows
an RS485 multi-drop wiring, with end-of-line termination. The controls can be wired in any order and
on any of the three links (on TB2, 3 & 4), however, they must follow the following rules:
1. Wiring must be from one station to the next without the use of “T-taps” or junction boxes.
2. Cable must be an “RS485” low capacitance cable, such as Belden 9729, Alpha 9360 , West
Penn D2402 or equivalent.
3. Each station must also have (3) #14ga wires, two for power, and the third for equipment ground.
4. All wiring must be in grounded conduit for protection against static and power line events.
5. All stations must be mounted in metal electrical backboxes.
6. All stations of the same type use unique ID numbers, no two shall be alike.
7. Line voltage wiring and wires of other circuits must be kept away from the control wires.
8. Wiring must not be “strapped” or tie-wrapped to conduit of power or other circuits.
9. Shield wire must be insulated and connected at each station before termination to the backplane
terminals.
10. Failure to follow these wiring rules may result in poor performance, intermittent station
operation or the voiding of the warranty.
4.3 Fire Alarm Input
There is a dedicated dry contact input available on TB11 for use with fire alarm systems or BMS
systems. When the terminals are shorted, the system activates “PANIC 2” in the SCM for any dimmer
that is configured to that Panic signal. The input is maintained, and will remain in panic as long as the
terminals remain shorted.
