devices must not exceed the power supply of the panel. In all
cases, the installer should consider the voltage drop to
ensure that the last device on the circuit operates within its
rated voltage.
• Wiring must be in accordance with CSA C22.1 Section 32
Description
The low frequency 400 series sounder provides a wide range of
low frequency audible settings in a single compact device. These
low frequency devices operate within a range of 520 Hz ± 10%
which address the NFPA 72 sleeping space requirements. The
low frequency sounder can be synchronized using an FACU or
PSU with the MGC protocol or through an external sync module
for compatibility with any UL/ULC listed FACU or PSU.
Sounder models are approved for wall and ceiling installations.

NOTE for SW2: Use NON-SYNCHRONIZED when the
appliances do not need to be synchronized. Use
SYNCHRONIZED when synchronization is required, either
through a sync module or built-in synchronization on the
control unit.
When SYNCHRONIZED is selected, the settings for DIP
switch SW1 are ignored.
When NON-SYNCHRONIZED is selected, the sounder will
sound only the audible pattern as selected through DIP
switch SW1.
