The QC000E-840 is an add-on Zigbee card that is made for the IQ Panel 4. It allows the panel to communicate with Zigbee devices. It adds support for compatible Zigbee automation and Zigbee security RF devices. It is an after-market add-on that must be installed inside the alarm panel.
Zigbee is a shared technology that is used in the security and automation industry. It is similar to Z-Wave but operates on its own unique wireless protocol. Zigbee uses a low-power, low-data mesh network to communicate between devices. It operates at 2.4 GHz, though some Zigbee devices use 784 MHz in China, 868 MHz in Europe, and 915 MHz in the US and Australia. This module allows support for 2.4GHz devices only.
If you currently have an IQ Panel 4 and want to expand your automation to include Zigbee, the Qolsys QC000E-840 is what you need. The IQ Panel 4, with the addition of this add-on card, will then be able to use the RF and Automation devices included in the IQ Panel 4 Zigbee compatibility list. The IQ4 has an open, available slot to install this Zigbee daughter card.
