Wiring the Contact Closure Input (CCI)
The contact closure inputs must be dry contact
closure, solid state, open collector, or active-low
(NPN)/active-high (PNP) output.
• Open collector NPN or active-low on-state voltage
must be less than 2 V and sink 3.0 mA.
• Open collector PNP or active-high on-state voltage
must be greater than 12 V and source 3.0 mA.
• The outputs must stay in the closed or open states
for at least 60 msec in order to be recognized by
the wallstation.
If there is any question as to whether the third-party
device generating these outputs is compatible with
these specifications, contact the manufacturer.

Note: If a wallstation has devices connected
to it through contact closure inputs,
CCI1 "presses" the top button and CCI2
"presses" the bottom button. To change
this behavior, refer to Application Note 428
(seeTouch
at www.lutron.com.
Exception: On a 2-button wallstation
configured for partitioning, panic, or
sequencing functionality, CCI1 closure
action follows the top button and opening
action follows the bottom button.
