Output termination
Output termination is required at all times, whether the output is used or not. The
type of termination depends on the output class, as shown in Table 13 below.
Table 13: Termination required for output classes
Output class
Output termination
Class B (default) All outputs require a 15 kΩ end -of-line resistor for termination. If
an output is not used, the end-of-line resistor must be installed
across the unused output terminals (see Figure 4 on page 9).
Class A (EN 54-13) All outputs require a 4.7 kΩ , 1/4W, 1% end -of-line resistor for
termination. If an output group (OUT1/2, OUT3/4) is not used, the
end-of-line resistor must be installed across the unused output
terminals (see Figure 5 on page 9).
See “Input and output specifications” on page 79 for details on voltage and
current ratings.
Output polarity
All outputs are polarity sensitive. Observe polarity or install a 1N4007 diode or
equivalent to avoid inverted activation issues.
Connecting sounders or other notification devices to supervised outputs
Depending on the operating mode, up to four sounder or notification device
circuits can be connected. See Table 11 on page 15.
