3.1.2 BATTERY MODULE
The Battery module supplies the EPIRB module with 7.2 VDC power to keep the
EPIRB transmitters active for 48 hours when activated, and for test sequences.
The battery module consists of four SAFT LSH14L Lithium-Thionyl chloride (Li-
SOCL2) batteries connected in series and is attached inside the lower house.
The housing is made of polycarbonate. In the lower part of the housing there
is one reed contact, which is activated by a magnet in the release mechanism.
This is the safety switch, which prevents the seawater contacts from activa-
ting the beacon while placed in the mounting bracket. There is a internal brass
weight, which gives stability while floating.
The seawater contacts are also mounted in the battery module, and are con-
nected to the electronic unit via the battery connector.
The batteries are mounted in a plastic battery holder.
3.1.3 EQUATOR RING WITH GASKET
The two parts of the housing are held together by the equator ring, and is locked
with a U-shaped bolt of stainless steel and a split pin. Between the two halves of
the housing there is a gasket made of neoprene.
