Purpose and Applicable Part/Model Numbers
This guide applies to all Comm/net products that have (2) 8p8c/Can (RJ45/Can) jacks for alarm daisy chaining.
Which connector is input which is output?
Many Comm/net products have (2) 8p8c/Can (RJ45/Can) jacks for alarm daisy chaining. The question often comes up which jack is the input and which is the output. The answer is that it does not matter. Both jacks are wired in common so you wire to either as long as you are consistent down the chain. However if you do daisy chain the alarms you will need to monitor the NO (Normally Open) condition.
