DETECTOR ACTIVATES SOUNDER BASE(S) - (COMPLIES WITH UL268)
UL has approved grouping for up to six B200SR-LF-WH or B200SR-LF-IV low frequency sounder bases. When wired as a group, any detector in the group that
has been activated by the panel will cause other B200SR-LF-WH or B200SR-LF-IV units in the group to sound. This type of “local” grouping is accomplished
by wiring the grouped devices together using terminal 6, Sounder Base Interconnect, as shown in the diagram. This interconnect can also be used to attach
B200SR-LF-WH or B200SR-LF-IV devices to System Sensor B501-Series sounder bases. Some Fire Alarm Control Panels (FACP) support the grouping of sounder
bases via software in lieu of the Sounder Base Interconnect.
NOTE: A local grouping of horns via the sounder base interconnect is not supervised, therefore the groups can only be used as a supplementary evacuation
system. It is not acceptable to group horns via the sounder base interconnect for primary alarm signaling. Sounder bases which are grouped via software are not
subject to this limitation and may be used as part of the primary alarm signaling.
