Power Requirements

When a PSU is dedicated to module network power, both outputs can be wired in parallel. In this configuration - using a 4 Amp power supply- a maximum module network load of 4A can be supplied. This includes all expanders and connected ancillary devices such as readers and PIRs.

The total average PSU loading should be kept below 75% of its rated output. This leaves adequate available supply for fluctuations caused by peak loading or if a field device should become faulty. It will also extend the service life of the power supply.
