The Crestron® Battery-Powered Wireless AV Keypad (ZUMMESH-KPAVBATT) can be mounted virtually anywhere to enable simple control of AV and other functions through integration with a control system or computer. Its slim design allows it to be attached directly to any suitable flat surface using screws or two-sided adhesive tape. It can also be mounted to a standard electrical box. One or more keypads can be mounted together, or alongside other decorator-style devices, and finished with an FP-G series faceplate (sold separately).
The ZUMMESH-KPAVBATT is battery powered and completely wireless. It can operate for five years or more on a single lithium coin cell battery (included). Connection to the control system or computer is facilitated using an AV Bridge (ZUMMESH-AVBRIDGE). No other wireless gateway is required. Zūm™ Mesh peer-to-peer wireless technology affords reliable operation with easy “pair and play” setup. Up to eight keypads can be paired with a single AV Bridge.[1,2]
The ZUMMESH-KPAVBATT is available with either four or six buttons, which may be ordered with custom button engraving  or pre-labeled for basic power, source selection, and volume control. Each button can be assigned to control any system function via the control system program or computer program.
The ZUMMESH-KPAVBATT is ideal for expanding the capabilities of a Zūm commercial lighting system to add control of AV and other system functions. Installed alongside Zūm lighting keypads and wall-box dimmers, they afford a cohesive appearance for every control on the wall.
