When the primary bank of cylinders is depleted, the manifold will automatically switch to the secondary bank
of cylinders without interruption of gas flow to the facility. The red LED will illuminate when the cylinder has
depleted (less than 40 psi total tank pressure).
In the event an audible alarm is required in multiple locations of a facility, the manifold is equipped with dry
contacts to allow for a remote buzzer to be installed. One or both sets of contacts may be wired to an external
alarm, remote buzzer and/or a building management system to indicate when an alarm condition occurs.
