B5-EPI-PCM partial indication and control map
Via the
Extended Bus
(EPI-BUS) by means of a patch cable and an
8-pin RJ45 plug, the partial indication and control map can be con-
nected 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-PCM 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 811 085.
