The above table also shows the maximum voltages at which
the sounders can be operated.
11) Cable Selection
Cables must be capable of handling the current drawn from
all of the units on the line.
SAFETY WARNING: If the high output BExS120E sounders
are used at high ambient temperatures, i.e. over +40ºC, then
the cable entry temperature may exceed +70ºC and therefore
suitable heat resisting cables must be used, with a rated
service temperature of at least 95ºC.
12) Earthing
Both AC and DC sounder units must be connected to a good
quality earth. The units are provided with internal and
external-earthing terminals, which are, both located on the
terminal chamber section of the unit (see figures 2 and 3).
When using the external earth terminal a cable crimp lug
must be used. The cable lug should be located between the
two M5 stainless steel flat washers. The M5 stainless steel
spring washer must be fixed between the outer flat washer
and the M5 stainless steel nut to ensure that the cable lug is
secured against loosening and twisting.
13) Cable Glands
The sounders have dual cable gland entries with M20 x1.5
entry threads. Only cable glands approved for Ex 'e'
applications can be used, which must be suitable for the type
of cable being used and also meet the requirements of the Ex
'e' installation standard BS EN 60079-14 : 1997.
SAFETY WARNING: If the high output BExS120E sounders
are used at high ambient temperatures, i.e. over +40ºC, then
the cable entry temperature may exceed +70ºC and therefore
suitable heat resisting cable glands must be used, with a
rated service temperature of at least 95ºC.
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer must be fitted under the cable gland.
When only one cable entry is used the other one must be
closed with an Ex 'e' Increased Safety blanking plug, which
must be suitably approved for the installation requirements.

17) End of Line Monitoring (DC Units)
On BExS120E and BExS110E DC sounders, dc reverse line
monitoring can be used if required. All DC sounders have a
blocking diode fitted in their supply input lines. An end of line
monitoring diode or an end of line monitoring resistor can be
connected across the terminals provided in the flameproof
enclosure. Note monitoring components must not be
connected to the terminal block in the Increased Safety
terminal chamber. See section 8 of this instruction manual
for access to the flameproof enclosure.
If an end of line resistor is used it must have a minimum
resistance value of 3k3 ohms and a minimum wattage of 0.5
watts or a minimum resistance value of 500 ohms and a
minimum wattage of 2 watts.
