B5-EPI-PIM partial indication map
Via the
Extended Bus
(EPI-BUS) by means of a patch cable and an
8-pin RJ45 plug, the partial indication map can be connected to any
SecuriFire MIC11 / MIC711 as well as to the B5-MMI-FIP and B5-
MMI-IPS devices.
Additional EPI devices can be connected to the second RJ45.
The B5-EPI-PIM is mounted either on the door of the SecuriFire or
immediately next to a remote SecuriFire indication and control
map.
Via the hex coding switch you can set one of the three possible
EPI-BUS addresses. For each MMI-BUS participant with an EPI-
BUS interface, up to three EPI devices can be connected.
More information about the B5-EPI-PCM can be found in the Tech-
nical Description T 811 084.
