Installation manual
SEP01 & SEP02 (17- 64 Zones, 17- 64 Outputs)
The Slave Expansion Panel SEP02 consists of a small boxed unit
(Unibox), with a 12V Slave Expansion Module consisting of 8 zones /
8-outputs and 1 Bell output. LEM boards model LEM01 can be
piggy-backed over this SEM PCB using 25mm posts. (16-zone boards
model LEM03, cannot be used with the SEP’s or for installations
with more than 24 zones). It is connected to the main panel via
three cores of the cable: KA, KB, and 0V. Screened cable MUST be
used. If other parts of the building may require keypads and
intercoms, then the Voice and Mic will be required at the SEP02.
Simply, use an additional two cores from the CPU run to the SEP02
from the Voice and Mic terminals. Each SEP02 can provide either
8-zone inputs and 8 outputs , or 16-zone inputs and 16 outputs if the
LEM01 is fitted within. If zone expansion is a future requirement, run
the comms cable to convenient expansion positions where the SEP02
panel may be mounted during the initial installation.
The SEP02 should be powered from the main CPU 12v supply or from
supplementary power supplies should the overall system current
required be greater than 850mA.
The SEP01 is the same PCB but is mounted within a large panel with a
230v power supply and battery backup support.
