Detector Activates Sounder Base(s) - (Complies with UL268)
UL has approved grouping for up to six B501BHT base 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
B501BHT units in the group to sound. This type of “local”
grouping is accomplished by wiring the grouped devices to-

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.
