4) Installation Requirements

Sounders must be installed in accordance with the following
or equivalent standards.
EN60079-14:2008 Electrical Installations in Hazardous
IEC60079-14:2007 (Ed4) Areas (other than mines)
EN60079-10:2003 Classification of Hazardous Areas
IEC60079-10:2008 (Ed1)
Installation should only be carried by competent personnel
and any local codes of practice applied.
5) Zones, Gas Group, Category and Temperature
Classification
The units can be installed in locations with the following
conditions:-
Area Classification:
Zone 1 Explosive gas air mixture likely to occur in
normal operation.
Zone 2 Explosive gas air mixture not likely to occur,
and if it does, it will only exist for a short time.

6) Sounder Location and Mounting
See drawing A
7) Safety Warning (Electrostatic Hazard)
The acoustic horn section is made of ABS Plastic; therefore
to avoid a possible ELECTROSTACTIC CHARGE the unit
must only be cleaned with a damp cloth.
8) 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.
9) 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:-
Unit Type Input
Voltage
BExS120D 24V DC
BExS120D 12V DC
BExS120D 48V DC
BExS120D 230V AC
BExS120D 110V AC
BExS120D 115V AC
