resentative, dealer, or employee of the Company has the authority to
increase or alter the obligations or limitations of this Warranty. The
Company’s obligation of this Warranty shall be limited to the repair or
replacement of any part of the Flow Switch Tester which is found to be
defective in materials or workmanship under normal use and service dur-
ing the three year period commencing with the date of manufacture. After
phoning System Sensor’s toll free number 800-SENSOR2 (736-7672) for a
Return Authorization number, send defective units postage prepaid to: System Sensor, Repair Department, RA #__________, 3825 Ohio Avenue,
St. Charles, IL 60174. Please include a note describing the malfunction and
suspected cause of failure. The Company shall not be obligated to repair or
replace units which are found to be defective because of damage, unrea-
sonable use, modifications, or alterations occurring after the date of man-

1. Zonecheck Flow Switch Testers may not work or operate properly if
sprinkler piping being monitored is plugged with pipe scale, mud,
stones or other foreign material. Sprinkler systems should be checked
regularly for such blocking material, following the instructions in
Chapter 5 of NFPA Standard 13A.
The Limitations of Zonecheck Flow Switch Tester
WARNING
2. All valves controlling a sprinkler water supply should be sealed or
locked in the normally open position. The normally open position
should be monitored by a sprinkler supervisory switch.
Please refer to insert for the Limitations of Fire Alarm Systems
Pre-Operation Guidelines
Contact central monitoring station or appropriate fire safety personnel
prior to testing Zonecheck.
Zonecheck Testing: Self-Test Mode
To activate the Zonecheck wired locally to the ZCK-1 key switch (refer to
stand-alone wiring diagram), insert key and turn to the right. The green
LED on the ZCK-1 will illuminate to show that the pump has been acti-
vated. The red LED on the ZCK-1 will illuminate once the waterflow detec-
tor has been activated. The red and green LEDs will remain illuminated
until the key is switched to the standby position. NOTE: The red LED will
not illuminate if the waterflow detector is not wired to the ZCK-1 key
switch. When testing has been completed, turn the key back to the stand-
by position.
Only activate the Zonecheck ZCK-1 key switch when the valves are
opened and the sprinkler system is full.
WARNING
Zonecheck Testing: Group-Test Mode
All Zonecheck systems whose ZCK-1 key switches are interconnected
(refer to interconnecting wiring diagram), may be activated from any ZCK-
1 key switch. To initiate the group test, insert key and turn to the left.
The LEDs on the key switch from where the group test was initiated only
indicate the activity for the Zonecheck connected directly to that key
switch. The red and green LEDs will remain illuminated until the key is
switched to the standby position.
When testing has been completed, turn the key back to the standby
position.
Trouble Shooting Recommendations for Zonecheck Flow Switch
Tester
The unit fails to activate the remote alarm signal
1. Is there power to the circulator, i.e. Zonecheck pump?
2. Is the impeller spindle turning? If not, switch off at the key switch.
Turn the spindle manually with a screwdriver for several turns then
switch on the keyswitch.
3. Is the circulator fitted correctly for the flow of water to move the pad-
dle?
4. Is the green handled valve fitted on the delivery side of the circulator?
5. Are the Zonecheck valves in the “open” position?
6. Is the signal wiring operating correctly? Check the wiring.
After installing a Zonecheck Automatic Flow Switch Tester:
1. Backfill and hydraulically test the system.
2. Contact central monitoring station or appropriate fire safety personnel.
3. Open the main isolation valve slowly until fully opened.
4. Open both Zonecheck valves fully.
