Zone Indicators A maximum of sixteen zones are possible: 6 on board, 12 on board with doubling and 16 with an additional expansion module. The indicators can blink (indicating an open sensor condition) or be on permanently (when the zone is violated) or be off, depending on the status or mode or operation of the system.

The ExpansE system utilizes an embedded web based management and supervision application, which controls up to 2048 Main Units (MUs) (EXP-1032 ExpansE Networked Controller), by creating a Master/Slave configuration of all available MUs within the network, each with their associated secondary units, referred to as End Units (EUs).
