3 Connection
Notice!
The units are usually connected to an additional power supply. When connecting to a Bosch
fire panel LSN improved version, the voltage is supplied via the AUX outputs of the Battery
controller module. Alternatively, an external mains unit (e.g. FPP-5000 or UEV1000) can be
used.
For motherboard with terminal blocks X8, X7, X6, refer to graphic 04, page 4 .

LSN Configuration
Once the aspiration smoke detector has been connected to the LSN, the detector and
detector module, or the two detector modules (FAS-420-TP2 and FAS-420-TT2), are
configured using the FSP‑5000‑RPS programming software via a laptop connected to the Fire
Panel.
Information on the LSN configuration can also be found in the Online Help feature of the RPS
programming software. Notes on diagnostics data for the fire panel are contained in the
operation guide for the FPA‑5000.
Notice!
Both a dual-detector dependency and a dual-zone dependency can be established when
connecting the FAS-420-TP2 and the FAS-420-TT2 to the Modular Fire Panel.
