Description
The low frequency 400 series sounder/strobe provides a wide
range of low frequency audible and visual 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/strobe 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/strobe models are approved for wall installations.

NOTE for switch 1: 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 switches
3, 4 and 5 are ignored.
When NON-SYNCHRONIZED is selected, the sounder will
sound only the audible pattern as selected through switches
3, 4 and 5.
Switch 2 is not used. By default it is OFF.
