This document contains important information on the installation
and operation of the Coil Supervisory Switch. Please read all
instructions carefully and notify the building owner or their
authorized representative before any work is done on the fire
sprinkler or fire alarm system. A copy of this document is
required by NFPA 72 to be maintained on site.
Description
The CoilKeeper ™ Supervisory Switch (CSS) is designed to supervise
the position of a coil on a solenoid for a preaction/deluge system as
required by NFPA 13. The unit monitors the coil electronically and
determines if the coil is installed on the valve stem. If a technician
removes the coil from the stem the CoilKeeper will activate a normally
open set of dry contacts that can be wired to a supervisory circuit of the
releasing control panel.
Local LEDs at the CoilKeeper shows when the coil is in a normal state
on the valve body, when the coil is removed from the valve body in
a maintenance state, when the releasing circuit is energized and if the
coil is open or shorted. The releasing circuit energized LED allows the
technician to locally see the state of the circuit, preventing accidental
release by re-installing an energized coil.
•Installation must be performed by qualified personnel and in
accordance with all national and local codes and ordinances.
•Shock hazard. Disconnect power source before servicing. Serious
injury or death could result.
•Read all instructions carefully and understand them before starting
installation. Save instructions for future use. Failure to read and
understand instructions could result in improper operation of
device resulting in serious injury or death.
•Risk of explosion. Not for use in hazardous locations. Serious injury
or death could result.
