Description
ISOLATOR-A is an IS isolator intended for use together
with Salwico intrinsically safe addressable detectors and
manual call points. It contains an IS-isolator and a LISA-2
connection board.
ISOLATOR-A is located in a non-hazardous area (safe
area) and forming the interface to IS detectors and other
IS line units.
To each addressable detector loop a maximum of five
ISOLATOR-A units can be connected, each of them
accommodating up to 20 IS line units.
ISOLATOR-A does not need a separate power supply or
earth connection. It is powered directly from the fire
alarm panel via the loop cable, which means that no extra
cables are needed.
The cable glands shall be mounted acc. to the dimension
drawing on page two. This will guarantee the minimum
required distance (50mm) between the intrinsic safe and
the non intrinsic safe conductors. The conductors shall be
as short as possible between the entrance and the
terminals and shall not cross from one side to another.
The connection board LISA-2 simplifies installation and
replacement by offering a connection solution without
breaking the fire alarm loop.
The resistor mounted on the ISOLATOR output should
not be removed.
