For flexibility and ease-of-use, Zūm wired keypads are preprogrammed so the keypad can be
installed in a room along with Zūm load controllers, occupancy or vacancy sensors, and a daylight
sensor, and then used to control the lights in the room without programming. Room setup can be
accomplished quickly through the Zūm app. A finished installation requires a decorator-style
faceplate (FP-G Series, sold separately).
Override Contact Closure Input
An integrated contact closure provides the means to place all connected Zūm Net and Zūm Link
devices into Emergency Override mode.
ZUMLINK-EXP-16A-DIMU
Auto-Detecting Universal Dimming
Under normal operation, the ZUMLINK-EXP-16A-DIMU detects the connected load type and
automatically selects the appropriate operating mode. Reverse phase (trailing edge) mode
supports incandescent and electronic low-voltage load types, while forward phase (leading edge)
mode supports LED, magnetic low-voltage, neon/cold-cathode, and 2-wire fluorescent load
types. Center phase mode is also available, combining reverse and forward phase load control to
address special cases. The operative mode is indicated by two LEDs located on the front panel.
Zūm Link Wired Technology
Zūm Link technology enables in-room lighting control through keypads and sensors wired to
controllers. Zūm Wired devices connect via CBL-CAT5E-ZUMLINK-P CAT5e cable (sold
separately, refer to Cables on page 14) to RJ-45 ports provide simple daisy-chaining and lighting
control of compatible loads. The Zūm Wired devices work together in a local ecosystem to
provide customized solutions using the Zūm app.
