Step 15. Open the (System) Downstream Shut-Off Valve (21), as will be the case when resetting a system after
performing an operational test.
Step 16. Previously in Step 9 for Electric/Pneumatic Actuation, the detection system was reset; however, at this
time for Electric/Electric Actuation, the Solenoid Valve (7) is disconnected via the Potter RCDS-1 Releasing
Circuit Switch, or equivalent.
For Electric/Electric Actuation, first proceed to reset the electric detection system in accordance with the
manufacturer's instructions. After setting the releasing panel, return the Potter RCDS-1 to "green light -
releasing circuit system normal".
Step 17.
Partially open the System Main Control Valve (2). Slowly close the Main Drain Valve (4) as soon as
water discharges from the Main Drain Valve (4). Observe the Automatic Drain Valve (3) for leaks. If there are
leaks, determine/correct the cause of the leakage problem before proceeding.
When the System Main Control Valve (2) is partially opened, the pressure on the DV-5A Diaphragm Chamber
may increase. This increase in pressure is normal, and if the pressure is greater than 300 psi (20,7 bar), the
pressure is to be relieved by partially and temporarily opening the Manual Control Station (8); however, do not
allow the pressure as indicated on the Diaphragm Gauge (15) to drop below the supply pressure shown on the
Water Supply Gauge (11), since this action may result in tripping of the DV-5A Valve.
Step 18.
Close the hinged cover on the Manual Control Station (8) and insert a new break rod in the small hole
through the top of the enclosing box.
Step 19.
Fully open the System Main Control Valve (2).
Step 20.
After setting a fire protection system, notify the proper authorities and advise those responsible for
monitoring proprietary and/or central station alarms.
