silent knight 6815 alarm:

The 6815 is a signaling line circuit (SLC) expander for use with Honeywell
Silent Knight 6820 or 6820EVS fire alarm control panels (FACPs)using
System Sensor® (SK) protocol. The 6815 signaling circuit has the same
functionality as the SLC that is built into the 6820 and 6820EVS panels
and support the same addressable devices as the one in each panel. The
number of 6815 SLCs that can be used within one system is largely
dependent on maximum available points. They provide a powerful way to
customize configurations in large or complex installs.

FEATURES

• The number of 6815 SLCs that can be used in one system is
largely determined by maximum point counts. With 1,110
available points on the 6820 and 6820EVS and 6815 SLC
flexibility, new design and installation opportunities are now possible.
• Use the 5815RMK mounting kit to securely house more SLCs within one system.
• Pair with the separate 6860 remote annunciator for additional installation
and operating options. The 6860 has four programmable
buttons that are useful for executing routine or complex tasks.
• Up to two additional 6815 SLCs can be
securely housed in one FACP, thus limiting the need for separate housing
• Useful for installations where buildings are connected for
multi-site benefits using fiber optic or copper wiring. The ability to use multiple
6815 SLCs in these situations provides additional fire system design options.
