Please kindly pay attention to different connection for JJ1. While connecting to DC load, the 2 connection mode for JJ1 are both ok, yet it is suggested to use it
under 12V,1A. While connecting to AC load, then JJ1 must be open (unplug the short-circuit port on main board). For safety consideration, it is recommended
to use external relays while connecting to AC load (As the right side figure shows).There are 4 short-circuit port on main board that refers to each alarm output
channels JJ1, JJ2, JJ3, JJ4, which are all in short-circuit mode by default, and must be unplugged while connecting to AC load.
Warnings! Short-circuit port must be unplugged on connect to AC load, and users should also use external relays to avoid device damage and shock hazard!
