There are eight 20mm knockouts provided in the top and eight knockouts
in the bottom of the cabinet. Other entry holes can be drilled as required.
To prevent water entering the cabinet, seal unused knockouts and any
top cable entries. Where possible, use bottom cable entry with cables
going down 100 mm below the cabinet before rising.

The General Purpose Outlet (GPO) must be wired by a suitably qualified
technician.
IMPORTANT: The factory-fitted earth loom under the mounting block
must be wired to the earth terminal of the mains outlet in order to
correctly earth the BOWS cabinet.
The cabinet has space for a pair of
12V 17Ah batteries which will
provide over 24hrs standby and ½
hr alarm load for a 100W system
with paging. This should be
sufficient for most systems.
The BOWS is supplied with a red
battery lead for joining the neg(-)
terminal on the 1st battery to the
pos(+) on the 2
nd
battery, and the
screws, washers and nuts required
for attaching the leads to the
batteries.
