LIOU Lite provides 4 inouts and outputs to a Hochiki analogue addressable detection loop in a compact and cost effective package.

The LIOU lite can replace up to four addressable modules in approximately the same space taken by one standard module and is ideal for applications where a concentration of I/O is needed in a limited space.

The modules can be addressed with the Hochiki, hand held programmer in the range 1 to 127.

All inputs and outputs are fully configurable for any action and for cause and effect via the Syncro Loop Explorer configuration utility.

The LIOU connects to the ESP loop as per all other ESP devices. Consider the maximum number of sub-addresses when using LIOU.

Each unit has an integral short circuit isolator which provides further cost and space saving.
