This is the same air pump as the HP40 except it has a pre-installed alarm mounted on the side. This eliminates the need for a control panel with a pressure switch. The alarm has a switch with 3 positions. MUTE, TEST, RUN.

RUN: During normal operation, the switch is in the "run" or center position.

MUTE: The "mute" position will silence the audible alarm while leaving the visual alarm operational.

TEST: The "test" position will activate both the audible and visual alarms to check to see if they are working.

This product can be used anywhere a normal HP 40 is used.
