DATA SHEET Fire Sets FLA

DAYLIFF FLA packaged Fire Sets are specially designed to provide automatic supply to multiple hose reel
or sprinkler outlets for firefighting installations. Standard sets combine parallel duty diesel and electric
powered supply pumps to ensure serviceability in all conditions as well as a jockey pump to maintain
system pressure. Particular features include:-
l Individual electric motor and Lister diesel engine powered Ajax pumpsets providing standby supply
in the event of electrical power failure
l Separate automatic jockey pump to maintain system pressure and regulate main pump operation
l Bellows type pressure switch controlled operation providing progressive jockey pump, electric
pump and diesel pump starting at reducing cut-in pressure
l Low maintenance diaphragm type pressure vessel to regulate pump cycling.
l Integral control panel providing automatic parallel operation of the supply pumps and
incorporating electrical protection and a DC battery charging system
l Compact frame mounted design incorporating necessary valves and piping for simple site
installation.

Systems are designed to give their rated output at 5 Bar and three standard sizes are available, 40, 60
3
and 100 m /hr with the two pumpsets operating in parallel, 50% standby output being provided in the
event of electrical failure. For particular applications special designs incorporating different equipment
arrangements and specifications are available.

For all firefighting applications high levels of equipment performance and dependability are vitally
important for the protection of both lives and property. Dayliff FLA Fire Sets combine quality
components, all carefully matched for optimal operational efficiency with Davis and Shirtliff's
unmatched pumping expertise and competitive pricing to provide effective, reliable and easy to install
firefighting solutions.
SPECIFICATIONS
Supply Pumps: Dayliff single stage end suction pumps featuring gland packing seal and heavy duty bearings
constructed from heavy duty cast iron with bronze impellers. Pumps models are selected to meet the design pressure and
flow rates. Detail performance curves are available on request.
Diesel Engine: Lister TR naturally aspirated air-cooled diesel engines fitted with automatic electric start, engine
mounted 13.5l fuel tank and a dual 50Ah battery set.
Electric Motor: TEFC squirrel cage 2-pole 2900 rpm electric motors suitably rated for the pump load.
Jockey Pump: Grundfos CH4-60 horizontal multistage centrifugal pump fitted with 1kW electric motor. The pump is
set to maintain system pressure at 4.5Bar thus avoiding cycling of the service pumps due to minor system leakages.
Pressure Vessel: Varem 300 litre vertical pressure vessel fitted with butyl rubber diaphragm. The oversized vessel
volume limits jockey pump cycling frequency to a maximum of 10 starts per hour.
Piping: Suitably sized piping and fittings are provided for direct suction and delivery line connections including
necessary isolating gate valves, non-return valves on the system outlet. The limit of piping is shown in the schematic
drawing.
Control Panel: Control panel incorporating incoming mains isolator and MCB, voltage control relay, MCB and star-
delta starter for the main pump, MCB and DOL starter for the jockey pump, pump run/trip/no water indicators, 12-Volt
DC power circuit for the engine and a DC battery charging system. The panel is integrally mounted as standard, though
can be supplied loose for remote installation if required.
