4.9.11 LSN1500A LSN improved Module 1500mA
This module can be used to connect an LSN loop with
– up to 254 LSN improved elements with a max. line current of 1500mA and a cable length
of up to 3000m (depending on configuration and cable type)
– up to 127 classic LSN elements with a max. line current of 300mA and a cable length of
up to 3000m (depending on configuration and cable type).
!
Caution!
The module may only be connected to a PRD0004A Panel Rail Long, where it requires two
slots (see ).
The module must be connected to the first two slots on the left of the panel rail.
Notice!
To ensure that the fire detection system is operated in compliance with EN 54‑13, each LSN
stub and T-tap must be terminated with EOL modules.
