Hello, teachers! May I ask what is the difference between coded manual alarm buttons and uncoded manual alarm buttons? Thank you!

One has an address, the other doesn’t.

Encoded types can be connected directly to the bus, while unencoded types can only be connected to the bus through address-enabled input/output modules.
