LX-2500 Limited Service with ATS
 Hubbell Fire Pump Motor Controllers with Automatic Transfer Switches (ATS) are
designed to comply with the latest standard of the National Fire
Protection Association for the installation and operation of centrifugal
Fire Pumps (NFPA-20).
Hubbell’s Model
LX-2500 limited service fire pump controllers monitor system operation
by means of an adjustable type pressure switch (high and low set
points). If system water pressure drops below the minimum pressure set
point, the controller brings the pumping unit on-line for a fixed period
of time governed by the running period timer. At the end of the fixed
running period, and if the system water pressure is above the pressure
switch set point, the controller will automatically shut down the
pumping unit.
These controllers
may be used, where acceptable to the authority having jurisdiction, for
control of small electric motor driven fire pumps and booster pumps with
a maximum of 30 hp.
Suitable for use
as service entrance equipment.
