3.7.3 Alarm Devices
– Supervised Output
The Alarm Devices Output can be used in different applications depending on how it is configured. It
can be configured as:
•
A supervised speaker line output if OWS zoning is required or
•
Internal 24V supervised alarm output, suitable where electronic sounders are used.
Warning: Ensure that the jumpers are correctly set as described in Table 5 Main Control Board
Jumper Settings page 17. Incorrect jumper settings may short circuit the system power outputs and
damage the boards.
The typical connection diagrams shown in Figure 15 and Figure 16 are used when supervised speaker
circuit (S) is required and Figure
17 when 24V supervised output is required.
3.7.3.1 Supervised Speaker Output
If the alarm devices output is used as a speaker output circuit, the speakers should then be connected
to the warning output on the SUB880 as shown in the connection diagram in Figure 15.

Figure 15 Typical Speaker Output Circuit
If the optional 4 Supervised Output Expansion Board SUB886 is used as a Speaker Zone Splitter, the
speakers must be connected to SUB886 outputs while the input is connected to the warning output on
the SUB880.
A typical connection where the four outputs of SUB886 are used to split a single speaker output into 4
supervised speaker circuits is shown in Figure 16.
