Installation of a single EOL
1. Connect the two cables at the end of the 100 V loudspeaker line to the Input 100 V LS on
the EOL board.
2. Connect the two cables from an Emergency Trigger Input on the Voice Alarm Controller to
TRGA on the EOL.
3. Connect the jumpers JP1 on the EOL as shown.
Figure 4.3: JP1 for single EOL
Installation of a multiple EOL in a daisy-chain
With a daisy‑chain configuration it is possible to:
– Supervise several loudspeaker lines with only one fault input.
– Supervise several branches of a loudspeaker line with just one fault input.
1. Connect the cable from the 100 V loudspeaker line to the terminal 100 V LS Input on the
EOL board.
2. Connect one cable from an Emergency Trigger Input on the Voice Alarm Controller to the
FIRST BOARD input on the EOL board.
Figure 4.4: JP1 for first EOL
3. Connect a 20 or 22 kOhm resistor in parallel with the Trigger input to connect more than
one EOL board on a single Trigger input and to supervise them.
4. Connect the EOL boards to the Trigger input as indicated previousl. This input should be
on the Controller or Router to which the loudspeaker lines it supervises are also
connected
Notice!
The last EOL board in line is connected in a different way than the other EOL boards. This is
required to supervise the whole EOL detection line against short circuit. Such a short circuit
will be reported as an Input Fault. A break in the detection line will be reported as a Line
Fault, just as a loudspeaker line failure.
