Event register The annunciator unit incorporates a separate higher level system (the SPA bus master). The for the serial event register which contains information on the time resolution between the channels is 5 ms. communication type of event and the channel number including a synchronous time stamp.
Auxiliary outputs The annunciator includes four auxiliary output relay is dedicated for control of an audible device relays. Two output relays act as group alarm and one relay acts as an auxiliary output element reflash output elements, one auxiliary output for the internal self-supervision function.
