Logic relay

Template:Base point It is a message forwarder. It can be used to fire many outputs at once from just one input, or, by being disabled, to break an I/O chain. It can also be very helpful for organization and keeping you from having to edit MANY instances of the same outputs, as opposed to just one.

After a logic_relay is triggered, it cannot be triggered again until all of its outputs are fired. This is useful for when a relay has a sequence of delayed outputs that shouldn't be repeated until the sequence is finished. This behavior can be disabled with the "Allow fast retrigger" spawnflag.
