AJAX PSU 8VDC-32VDC HUB2 Power Supply for AJAX Control Panels

The AJAX PSU 8VDC-32VDC HUB2 is a dedicated power supply unit for the AJAX wireless alarm system. Control panels such as the AJAX hub need a stable power source to run the system, communicate with sensors and keypads, and report events. This power supply unit is intended to provide that source as part of an AJAX installation.
Supported devices and input range
The supplier description names two input ranges, which point to different AJAX devices. The unit is listed for an input of 8VDC to 32VDC when used with the AJAX HUB2. For the AJAX HUB, the AJAX HUB Plus and the AJAX ReX range extender, the listed input range is 8VDC to 20VDC. Before you connect the unit, confirm which hub or extender you have and make sure your power source matches the range listed for that device.

Installation considerations
Plan the location of the power supply so that the connected device is within reach of the wiring and the supply is kept in a suitable place. Match the input voltage to the specification of the device you are powering. Keep the wiring neat and check the connections before switching on the system. If you are unsure which input range applies to your setup, consult the documentation for your AJAX hub or ask a qualified installer.
