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.
