Wires having a cross sectional area between 0.5 mm² to 
2.5mm² can be connected to each terminal way. If an input 
and output wire is required the 2-off Live/Neutral or +/- 
terminals can be used. If fitting 2-off wires to one terminal 
way the sum of the 2-off wires must be a maximum cross 
sectional area of 2.5mm². Strip wires to 8mm. Wires may also 
be fitted using ferrules. Terminal screws need to be tightened 
down with a tightening torque of 0.56 Nm / 5 Lb-in. When 
connecting wires to the terminals great care should be taken 
to dress the wires so that when the cover is inserted into the 
chamber the wires do not exert excess pressure on the 
terminal blocks. This is particularly important when using 
cables with large cross sectional areas such as 2.5mm². 
 

8) AC 

Wiring 

 

3-off 2-way terminal blocks are provided on the AC beacon 
for power. There are 2-off Live, 2-off Neutral and 2-off Earth 
terminals in total.

Wiring 

 

3-off 2-way terminal blocks are provided on the AC beacon 
for power. There are 2-off +ve, 2-off –ve, 1-off Stage 2 and 1-
-off stage 3 terminals in total.

9.2 Line 

Monitoring 

 

On D2xB1LD2 DC units, DC reverse line monitoring can be 
used if required. All DC beacons have a blocking diode fitted 
in their supply input lines. 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 the following values: 
 
24V DC applications 
 
Minimum resistance 3K9 Ohms 

Minimum Power 0.5W 

Minimum resistance 1K Ohms 

Minimum Power 2.0W 

 
48V DC applications 
 
Minimum resistance 15K Ohms 

Minimum Power 0.5W 

Minimum resistance 3K9 Ohms 

Minimum Power 2.0W 

 
The resistor must be connected directly across the +ve and  
-ve terminals as shown in the following drawing. Form the 
resistor legs as shown in Fig. 8a, remove the +ve and –ve 
terminal plugs and fit the resistor across the two terminal 
plugs before refitting them to the PCBA as shown in Fig. 8b. 
A spacing of at least 1/16” (1.58mm)

 

must be provided 

through air and over surfaces between uninsulated live parts.
