Limitations [➙ 6]
 Building level network (BLN) port for communication with the host system via
Ethernet
 FLN1-3 can also be changed to RS232 communication port for Modem or
Elevator Integration.
The AC5102 also has a USB diagnostic port that provides a direct connection to its
micro-processor to facilitate the download of operating instructions (firmware).
Firmware updates can be made without having to visit the controller cabinets.
Communication to the host system occurs via a 10/100Mb Ethernet connection.
This allows communications over any WAN or LAN where devices on the network
can be as-signed a unique IP address. This type of communication ensures the
fastest possible transaction times between the host system and AC5102 field
panels.
The AC5102 hosts a tamper input that can be used to detect if the cabinet in which
it has been mounted has been opened. It also provides an alarm output that can
operate a visual or audio alarm when security has been breached.
