Siemens Central communication unit OCI611 CE1N2533en
Building Technologies 27.02.2009
The green LED indicates the operating state of the unit:
• LED lit: mains voltage present
• LED flashes: communication via LPB and/or RS-232, indication of the number of
units
The red LED shows the alarm status of the unit:
• LED dark: no fault and no alarm present
• LED lit: fault of one or several LPB units present
• LED flashes: internal fault of the central communication unit or signal at the digital
inputs
This selector is used to select whether the central communication unit is to be con-
nected to the RS-232 via modem or directly to the PC.
The LPB/BSB button serves for generating the device list and for indicating the number
of units contained on the list.
The modem reset button is used for reinitializing the modem. Then, the central commu-
nication unit establishes a connection to the parameterized alarm receivers and deliv-
ers a status report.
Mounting notes
The central communication unit can be fitted in any position, either on a wall mounting
rail or directly on the wall.
Please observe:
• If no protection against electric shock hazard is provided (e.g. in heating rooms,
false ceilings or false floors), the use of terminal covers is mandatory.
The terminal cover on the mains voltage side must be secured with cable ties
• If protection against electric shock hazard is ensured (e.g. in control panels or cabi-
nets), the unit may be mounted without terminal covers
• The heat generated by the unit during operation must be allowed to escape. Ade-
quate circulation of air must therefore be ensured
• Good accessibility for service staff must be ensured
• The local regulations for installations must be complied with
Mounting instructions are printed on the unit’s packaging.

service interface and the LPB/BSB.
The parameters can be set either beforehand or on site
• The telephone provider and the modem must be selected prior to commissioning,
depending on the type of alarm receiver in use
