This enables an extended suppression time even up to minutes in duration. For example, with the reservoir 26 able to hold 40 litres and with a 12 litre per minute pump, the fire suppression system 14 will operate to dispense for over 2 minutes. Thus, in addition to offering double redundancy if used in tandem wi th another fire suppression system, the above system 10 can extend suppression time over existing systems that have a relatively shorter operating time. Thus, the fire suppression system 14 is better able to fully extinguish fires with less chance of re-ignition.
