General Description
The National Fire Protection Association has published
standards and recommended practices for the installation
and use of the above appliances. It is recommended that
the installer be familiar with these requirements, with local
codes, and any special requirements of the local fire au-
thority having jurisdiction.
The signaling strobes are intended to be connected to the
alarm indicating circuit of a UL-listed fire alarm control
panel and are compatible with DC line supervision. Models
RK2415ADA, RK2475ADA,
RK241575ADA require 24 volt panels. Panels may have
full-wave rectified, unfiltered power supplies. The strobes
produce one flash per second (nominal) with continuous
