Claims

1. A system of operating a plurality of fire extinguishing units, comprising:
a plurality of valve control units each set to activate one of the plurality of fire extinguishing units when triggered and to trigger the activation of another of the plurality of fire extinguishing units by another of said plurality of valve control units substantially simultaneously;
an actuating element which triggers one of said plurality of valve control units; and
at least one mechanical linkage each connecting between two of said plurality of valve control units, each said valve control unit triggering said another valve control unit by driving one of said at least one mechanical linkage.
2. The system of claim 1, wherein said actuating element triggers the activation of all said plurality of fire extinguishing units by triggering said one of said plurality of valve control units.
3. The system of claim 2, wherein the activation of all said plurality of fire extinguishing units is performed by a mechanical chain reaction.
4. The system of claim 1, wherein plurality of valve control units are set to be connected in a chain by a plurality of mechanical linkages.
5. The system of claim 1, wherein each said valve control unit is set to activate one of said fire extinguishing units by manipulating a discharge valve thereof.
6. The system of claim 1, wherein each said valve control unit mechanically activates one of the plurality of fire extinguishing units.
7. The system of claim 1, wherein each said fire extinguishing unit is detachably connected to a respective said valve control unit so as to allow detaching any of said the plurality of fire extinguishing units without triggering any other of the plurality of fire extinguishing units.
8. The system of claim 1, wherein each said valve control unit mechanically triggers said another valve control unit.
9. The system of claim 1, further comprising a fire detection unit for activating said actuating element in response to the detection of a fire indication.
10. The system of claim 9, wherein said fire detection unit comprises a mechanical heat activation device.
11. The system of claim 1, wherein each said fire extinguishing unit is detachably connected to a respective said valve control unit so as to allow the detaching thereof without disassembling said valve control unit.
12. A system of operating a plurality of fire extinguishing units, comprising:
a plurality of valve control units each performs an activation of one of the plurality of fire extinguishing units when being triggered; and
at least one mechanical linkage each connecting between two of said plurality of valve control units;
wherein each of a group of said plurality of valve control units is set to trigger another of said plurality of valve control units by driving one of said at least one mechanical linkage simultaneously with said activation.
13. The system of claim 12, wherein said at least one mechanical linkage is a flexible cable.
14. The system of claim 12, further comprising a single detection unit which detects at least one fire indication and triggers one of said plurality of valve control units in response to said at least one fire indication.
15. A method of operating a plurality of fire extinguishing units, comprising:
activating a first of the plurality of fire extinguishing units using a mechanical lever; and
driving a mechanical linkage connected to a valve control unit to activate a second of the plurality of fire extinguishing units;
wherein said activating and driving are performed simultaneously by maneuvering said mechanical lever.
16. The method of claim 15, wherein said driving comprises pulling said mechanical linkage.
17. The method of claim 15, wherein said driving triggers a maneuvering of an additional mechanical lever set to activate said second fire extinguishing and to drive an additional mechanical linkage connected to an additional valve control unit to activate a third of the plurality of fire extinguishing units.
18. A method of setting a fire suppression system having a plurality of fire extinguishing units, comprising:
mounting a plurality of valve control units in a plurality of surfaces in a space;
setting each said valve control to activate one of the plurality of fire extinguishing units in response to the triggering thereof;
establishing a mechanical linkage between each two of said valve control units; and
connecting a first of said valve control units to an actuating element set to trigger one of said valve control unit;
wherein a triggering of said first valve control unit activates one of said plurality of fire extinguishing units and drives mechanical linkage to trigger all other of said valve control units.
