WATER LEVEL AND LOW AIR ALARM TESTS
The authority having jurisdiction may have standards that require water
level and low air alarm tests on a more frequent basis than national
requirements. Verify these requirements by contacting the authority
having jurisdiction in the affected area.
NOTICE
If a Series 746-LPA Dry Accelerator is installed, make sure the
authority having jurisdiction is notified that the water level and
low air alarm tests are in progress. Failure to close the isolation
ball valve of the Series 746-LPA Dry Accelerator may cause the
valve to trip, resulting in a false alarm.
