Detector Activates Sounder Base(s) - (Complies with UL268)
UL has approved grouping for up to six B501BH bases with
horn units. When wired as a group, any detector in the group
that has its LED’s latched on by the panel will cause other
B501BH units in the group to sound. This type of “local” group-

NOTE: Since a local grouping of horns is not supervised, the
groups can only be used as a supplementary evacuation system.
It is not acceptable to group horns for primary alarm signaling.
