The IU2055NC is connected to the panel via a two-wire communication loop that provides power and carries control and input data. The module address is easily set with two rotary switches. The address setting is non-volatile and will not be lost in the event of a power failure.
The 2000 series conventional zone monitor utilizes an advanced digital data communications protocol that ensures the integrity of the data communication with extensive error correction algorithms.
