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.

CoilKeeper™
Solenoid Supervisory Switch Series
On Valve Installation
Mounting
Install CoilKeeper on valve using supplied 1/2” pipe nipple and
locknuts as shown in Figure 1 or other 1/2” nipple as needed.
Note: CoilKeeper can be mounted using any of the 3 conduit
entrances and rotated to ensure clearance of trim piping. Install
liquid tight cord grip into CoilKeeper housing. Do not tighten outer
nut at this time.
Sense Return Clamp Installation
(see Figure 2)
1. Position the return clamp around the wrenching ats of the
valve.
Note: Mounting location should have parallel at edges.
2. With the valve centered in the bracket, adjust the set screw
until it is touching the valve.
Note: For larger valves, the locknut can be moved to the
outside of the U bracket for more clearance.
3. Tighten the locknut to prevent the set screw from moving.
4. Adjust the lock screw until the bracket is securely connected to
the valve.
5. Attach the blue sense return wire to the set screw using the
provided ring terminal washer and nut.
Sense Feed Bracket (see Figure 1)
3 Wire Valves: The sense feed bracket is not required on 3 wire
valves.
2 Wire Valves:
1. Install conduit nut onto supplied 1/2” pipe nipple or other 1/2”
nipple as needed.
2. Install sense feed bracket onto nipple with screw facing
solenoid coil.
3. Thread nipple into solenoid valve and tighten conduit nut.
4. Check that there is continuity between the solenoid coil collar
and sense feed bracket.
5. Attach yellow sense feed wire using provided ring terminal and
screw to the sense feed bracket.

CoilKeeper™
Solenoid Supervisory Switch Series
Solenoid coil / valve assembly is grounded through the
CoilKeeper sense return clamp.
Wiring
• Fault on releasing circuit may indicate improper wiring.
• End of line device must be installed between REL+ / EOLD
and SOL / EOLD terminals.
• Refer to releasing panels manual for end of line device types,
end of line devices show in diagram are for reference and
are not in addition to those required by the releasing panel for
supervision
• Do not wire ground to CoilKeeper when using 2-wire solenoid
valves.
• Ensure excess wiring does not interfere with the reset switch
or LEDs when cover is installed.
Sense Feed and Return Wiring
1. Push the un-stripped sense feed and sense return wires through
cord grip.
Note: Supplied cord grip has opening for 3 wires.
2. Cut excess wiring and tighten the outer nut of cord grip to
secure wires.
3 Wire Valves:
1. Wire solenoid ground to sense feed terminal on CoilKeeper.
2. Wire ground to sense return terminal if required by NEC, local
electric code or AHJ.
Ensure proper routing and slack of sense feed and return wires
so coil can be removed from valve without strain on wires.

CoilKeeper™
Solenoid Supervisory Switch Series
Testing
1. The CoilKeeper and its associated protective monitoring system
should be tested in accordance with applicable NFPA codes and
standards and/or the authority having jurisdiction (manufacturer
recommends quarterly or more frequently).
2. Remove the coil from the valve. The CoilKeeper will show an
amber LED stating coil removed and the releasing control panel
will annunciate a supervisory condition.
3. Reinstall the coil onto the valve. Ensure all of the coil
retaining hardware is installed to solenoid valve manufactures
recommendations.
4. Press the reset button on the CoilKeeper.
Note: If CoilKeeper fails to reset a local error code will be
ashed. Refer to troubleshooting for more information.
Failure to de-energize the coil prior to reinstalling the coil may result
in an accidental release.
An uninsulated section of a single conductor should not be looped around
the terminal and serve as two separate connections. The wire must be
severed, thereby providing supervision of the connection in the event that
the wire becomes dislodged from under the terminal. Failure to sever the
wire may render the device inoperable risking severe property damage and
loss of life.
Do not strip wire beyond 3/8" of length or expose an uninsulated conductor
beyond the edge of the terminal block. When using stranded wire, capture
all strands under the clamping plate.

ashes
Failed to reset: shorted / open coil
Red Solid Releasing circuit energized
Failed Continuity:
Check sense feed (yellow) and sense return (blue) wires for damage
and replace if required.
Check for continuity between sense feed terminal and valve body.
If no continuity, ensure coil is properly installed on body following
manufacturer’s instructions and all fasteners are tight. If the
CoilKeeper fails continuity remove the coil and ensure the stem and
base are clean and no obstruction exists between the coil and the
base. On some coils, it may be required to remove some plastic,
over molding ash, from the bottom of the coil to ensure a good
connection.
Check continuity between sense return terminal and the valve body.
Adjust or reinstall the sense return clamp to restore continuity.
Failed Inductance:
Ensure coil is properly installed on valve body following
manufacturer’s instructions.
Shorted or Open Coil/Incompatible Solenoid Coil:
Ensure proper wiring of coil and EOLD. If no wiring issues are
found replace the coil.
Notify the building owner or their representative before testing
the CoilKeeper. Testing of the CoilKeeper will result in a
supervisory condition on the releasing panel which may be
transmitted to the monitoring station. It may be possible to
silence the trouble buzzer on the releasing panel by pressing
the SILENCE or ACKNOWLEDGE button on the releasing
panel. Resetting the CoilKeeper should result in the releasing
panel restoring to normal. If the releasing panel does not
automatically restore to normal, press the reset button on the
releasing panel.
Prior to troubleshooting ensure solenoid coil is compatible
with CSS model installed, use of incompatible solenoid coil as
referenced in the technical specication will result in a trouble
condition that will not restore
