frequency.
• A dual-channel barrier or double intrinsically safe connection is required.
Tone switching using reverse polarity
• Connect the leads according to the figure.
• Supply with power to activate the first sound tone frequency.
• Reverse the polarity to activate the second sound tone frequency. The sounder PCB
and beacon PCB must be wired independently if using reverse polarity to switch
between sound tone frequencies.

7.3.5 Line monitoring
Standard termination with monitoring resistor fitted.
7.3.6 Sound tone selection
17784E00
• Arrange the settings of the DIP switch using a suitable tool:
• DIP switch "up" corresponds to "1"
• DIP switch "down" corresponds to "0"
Refer to the following tone table for the tone selection.
If line monitoring is required, this can be achieved by using an end-of-line
resistor. For this purpose, use a wire-wound or metal layer resistor with a
resistance value of at least 750 Ohm and a rated power of at least 2 W or at
least 4700 Ohm and a rated power of at least 0.4 W!
The line monitoring facility allows the integrity of the line to the sounder to be
monitored through the barrier to the control system fault detection and
indication circuits. Two sounders of the same type can be connected in
parallel. The resistor can be fitted as per the diagram below.
Line monitoring is optional. The system designer should inform users if this is
necessary or not.
