11.  AC Wiring 

 

A 4-way terminal block is provided on the AC chamber beacon 
for power. There are 2-off Live and 2-off Neutral terminals in 
total.  A  4-way  terminal  block  is  provided  on  the  AC  cover 
beacon  for  power.  There  are  2-off  Live  and  2-off  Neutral 
terminals in total.

Line Monitoring 

 

On BExCBGL2-L2D DC units, 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 +ve and –ve terminals. If an end of line resistor is used it 
must  have  a  minimum  resistance  value  of  3k3Ω  and  a 
minimum power rating of 0.5 watts or a minimum resistance 
value of 500Ω and a minimum power rating of 2 watts. 

 

The resistor must be connected directly across the +ve and -
ve terminals as shown in the following drawing. The resistor 
leads should be kept as short as possible.

13.  Flash Rate Settings 

 

 

The BExB2L2D beacons can produce different flash patterns 
as  shown  in  Table  1.  The  flash  patterns  are  selected  by 
operation of the flash setting DIP switch on the PCB, Fig 9.
