115 +There are a handful of limitations to keep in mind when designing Zūm Wired systems, with different restrictions applying to Zūm Net and Zūm Link:
116 +
117 +Zūm Net limitations:
118 +
119 +* Do not exceed 100m or 328' between subsequent ZUMNET-JBOX-* devices, or between the first ZUMNET-JBOX and the network switch
120 +* Do not exceed 20 ZUMNET-JBOX-* devices on a single run of Zūm Net
121 +* Do not "loop" Zūm Net cables (i.e., cables should start at the network switch and end at the last ZUMNET-JBOX, without a returning cable from the last device back to the switch)
122 +
123 +Zūm Link limitations:
124 +
125 +* Do not exceed 31 ZUMLINK-* and Cresnet devices on a single ZUMNET-JBOX-* device
126 +* Do not exceed 85mA of 24VDC power consumption per ZUMNET/ZUMLINK-JBOX-* device on the Zūm Link bus
127 +** Each ZUMNET/ZUMLINK-JBOX-* is limited to 85mA of 24VDC output shared across their Zūm Link ports and sensor inputs
128 +** Power is shared between ZUMNET/ZUMLINK-JBOX-* devices on a single Zūm Link bus, so adding more ZUMNET/ZUMLINK-JBOX-* devices to a network increases the available power
129 +** ZUMLINK-IR-QUATTRO-HD-DLS/RLY occupancy sensors are rated at 32mA of power consumption
130 +** Other ZUMLINK-OCC-* sensors are rated at 25mA of power consumption each
131 +** ZUMLINK-KP keypads do not have a listed power consumption, but designing for approximately 20mA is safe
132 +* Available power on the Zūm Link bus can be increased by adding additional ZUMLILNK-JBOX-* devices, or by adding a separate power pack to provide power for non-system sensors or Cresnet devices on the Zūm Link bus
