Low Standing Pressure – The system now operates off a flow switch rather than a pressure switch. This means that the system will eventually drop down to mains water pressure and sit there indefinitely without calling the pumps to work. Previously any loss in pressure due to a small leak in the distribution pipework could cause the pumps to come on at undesirable times. Now the system sits at mains water pressure and will not bring the pumps on unless there is a significant flow of more than 0.5lpm.
Actuated ball valve – Previously after the pump had finished its run time it would cut power to the pumps however it would still be able to run indefinitely at mains water pressure. We have now integrated an actuated ball valve which will shut off the water supply and the power to the pumps following elapse of the selected run time.
Drip tray with float switch – There is always a risk of damage to products during transit or installation. The risk of damage to property as a result of internal components leaking is almost eliminated with the addition of a drip tray and float switch within the base of the pump enclosure. In the event of any escape of water from damaged components the float switch will operate and close that actuated ball valve to shut off the water supply to the pump.
Corrosion resistance – The internal pump components are now made of the highest quality corrosion resistant materials.
Robust operation – There are no solenoid or pressure relief valves that run to permanent drain. This avoids any problems associated with dirt under the seals which could result in a small escape of water and pumps running at undesirable times.
Adjustable pump run time – The pump runtime can be adjusted with a dil switch to suit 30min (Residential) or 10min (Domestic) depending on the category of the system.
Pre-action / Double Knock Operation – With any water based fire suppression system there is always risk of unwanted operation through accidental or malicious damage to pipework or nozzles/sprinklers. The discharge of water could be potentially damaging to the property the system is protected.
