Important

This instruction manual contains important information
about the installation and operation of this supervisory
switch. This manual should be left with the owner/user of
this equipment.
General Information
The unit is intended for supervision of non-rising stem gate
valves and other valves that cannot be monitored by con-
ventional supervisory switches. Turning the valve wheel
will pull the plug out of the jack and close a set of normally
open contacts. A lockout will prevent reinsertion and re-
quire removal of the cover. Tamperproof screws are pro-
vided for the cover. Removal of cover, or cutting of cord or
ground faults will cause an open circuit. The device should
be wired to the trouble circuit of a fire alarm control panel.
Installation
1. Choose a location near the valve (safe from flooding)
and mount the bracket to the wall.
2. Rotate the box on the bracket until the plug faces the
valve. The plug must also point downward. Tighten the
locknut on the pivot.
3. Turn the valve to the full-open position. Insert the plug
into the jack. Tightly loop the 8-ft. waterproof cable
through the valve wheel and back into the box through
the cable clamp. Close valve to check that plug pulls out
and then turn valve back to full-open position. Cut the
cord to the minimum length required to make the con-
nections within the box.
4. For all exterior applications, use
1
/2″ NPT, listed liquid-
tight conduit connectors.
5. Wire the device as per the circuit diagrams shown (see
Figures 2-5). Trim the unused black wire flush with the
cable casing and cap the red wire of the cover tamper
switch.
6. If a longer cable is required, use SJOW A 16-2, two con-
ductor 16-gauge stranded rubber-jacketed cable.
7. Using the adhesive pad and wire tie provided, dress the
wires away from the lock-out mechanism.
8. When installing the cover, make sure the O-rings are in
place on the cover screws beneath the cover.
