6) Sounder Location and Mounting
See drawing A
7) Access to the Flameproof Enclosure
See drawing B
Note the four M6 screws are Class A4-80 stainless steel
and only screws of this category can be used on these
sounders. It is therefore important that these screws and
their spring washers are kept in a safe place during
installation.
8) Power Supply Selection
The system power supply must have the necessary capacity
to provide the input current to all of the sounders connected
to the system.
The following table shows the input current taken by the
various sounder units:-
