Wiring the Tamper Switch
Tamper switches integrated on the OSY-TS model of Series
C200, C300, LFC300, 2000SS, and 3000SS assemblies add
protection against fire.
The supervisory tamper switch consists of two SPDT switches.
The device is designed to send a signal when the valve is closed
and when the switch is removed from the valve. In the neutral
position, the switch indicates the valve is fully open. Closing
the valve causes the switch rod to come out of the valve stem
groove, activating the switch. Removing the device also acti-
vates the switch.
Connect the wires to a fire alarm control panel in accordance
with the schematic diagram and the wiring notes on page 2.

CAUTION
!
Before wiring supervisory switches in fire protection systems,
refer to the following standards:
NFPA 13: Standard for the Installation of Sprinkler Systems
NFPA 25: Inspection, Testing, Maintenance of Water-based Fire
Protection Systems
NFPA 70: National Electrical Code
NFPA 72: National Fire Alarm Code
CSA C22.1 NO.1 Canadian Electrical Code, Part 1, Safety
Standard for Electrical Installations Section 32
CAN/ULC-S524, Standard for Installation of Fire Alarm Systems
WARNING
!
• Metallic conduit required by NEC for proper grounding conduit
joint must be sealed with a conductive sealant.
• Install switch in accordance with National Electrical Code and/
or local ordinances.
• Wiring methods shall be in accordance with CSA C22.1,
Canadian Electrical Code, Part 1, Safety Standard for Electrical
Installations, Section 32 and CAN/ULC-S524, Standard for
Installation of Fire Alarm Systems Assure All Devices Are
Properly Grounded.

Wiring Notes
• Connection to power limited circuitry is required.
• The auxiliary switch is for supplemental use only and shall not
be used for fire alarm signaling applications.
• Switch functions are checked at the factory. Checking the
switch after field installation is strongly advised. Check conti-
nuity with the valve fully open. Switch functions activate within
two (2) turns from open.
Field Service of Installed Tamper Switch
Field repair by anyone other than authorized (factory) personnel
is not recommended. Consult factory before attempting any
repairs. Tamper resistant tools are required. Limited internal parts
are available.
All replacement parts must be obtained from the manufacturer
to assure proper operation of the valve and to maintain agency
approval of the device.
Field Installation of Tamper Switch
1. Close the valve.
2. Remove the wheel nut with an appropriate-sized open end
wrench.
3. Remove the handwheel.
4. Screw the switch unit into the tapped hole until the bushing
is flush with the inside of the yoke.
5. Tighten the nut against the yoke with an open end wrench to
50 ft-lb minimum.
6. Reinstall the handwheel.
7. Open the valve until the trip arm is halfway into the groove.
8. Remove the security plug.
9. Using a 9⁄16" socket with extension, loosen the adjustment
nut until it depresses the switch tab; counteract rotation
of the trip arm with a 9⁄16" open end wrench. Listen for
two clicks.
At this point there should be continuity through the brown
and yellow leads. The brown with orange stripe and yellow
with orange stripe leads must have continuity as well.
10. Open the valve fully, so the trip arm is seated in the groove.
At this point the blue to yellow leads and blue/orange to yel-
low/orange leads must have continuity. If both switches are
not in unison, further adjustments must be made.
NOTICE
The switch must meet this specific installation so that closing
20% of the valve or making a maximum of four (4) revolutions
causes the switch to change status. Verify this after setting
the limits.
Field Rotation of Tamper Switch
1. Loosen the nut against the yoke with a 1¾" open-end wrench.
2. Rotate the switch to the desired position and tighten the nut.
3. Perform steps 7 to 10 in the preceding procedure to ensure
the switch function.
