The power supply comprises a steel case containing a pcb (printed circuit board) and space for up to two 17Ah backup batteries. The unit can monitor and charge each battery independently and an installer can use combinations of batteries to meet their standby requirements.

The pcb also provides connectors for four transistorised outputs, 16 plug-by communicator outputs (mirroring those on the control unit), and up to 10 FSL (Fully Supervised Loop) or five CC (Closed Circuit) zones.

The EXP-PSU connects to the i-on control unit and the rest of the alarm system by means of the system bus, providing monitoring messages to the control unit over the bus. These messages include Remote PSU Fault, Remote AC Fail, Remote Battery Fail, and Remote Low Output Voltage.

During installation the EXP-PSU uses the same semi-automatic addressing procedure as other i-on expanders. The unit also provides an audible locator and allows power monitoring through the system keypads or the web-browser within the i-on control unit.

The EXP-PSU is designed and approved to be used as part of a Security Grade 2 or 3 system
