Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
In an automatic fire alarm and extinguisher device forming part of a fixed relatively permanent central fire alarm and extinguisher system which includes a central station and a common central supply of extinguisher fluid for a plurality of extinguisher outlet heads operatively connected thereto over fixed piping, the combination of a unitary fire protection unit adapted to monitor a predetermined zone, comprising alarm means operatively connected to the central station by a fire-protected, monitored electric line, a valve, operatively connected by fixed piping to said central fluid supply, and control means operatively connecting said alarm means and said valve for opening said valve upon predetermined operation of said alarm means, a protective housing of a size to operatively contain primarily only said valve and said alarm and control means, and at least one extinguisher outlet head, remote from said housing and said valve, and operatively connected thereto only by fixed piping which extends from said housing to said head.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
28 words
A device according to claim 1, wherein said alarm means comprises a smoke detector and a heat or flame detector, which are accommodated in the common protective housing.
Claim 4
Dependent Claim
43 words
A device according to claim 1, wherein an additional extinguisher outlet head also is provided, the protective housing being of a size to also operatively support such additional extinguisher outlet head, as well as piping operatively connecting such additional head and said valve.
Claim 5
Dependent Claim
38 words
A device according to claim 1, wherein a plurality of extinguisher outlet heads are provided, covering a specific extinguishing zone, which are supplied in common from the valve means disposed in the protective housing over relatively fixed piping.
Claim 6
Dependent Claim
69 words
A device according to claim 4, wherein respective extinguisher zones are provided, each of which has its own respective fire protection unit and a plurality of extinguisher outlet heads, which zones operatively overlap, as a result of the arrangement of the individual extinguisher outlet heads of the respective zones, whereby the overlapping area of the zones is protected by at least one outlet head of each of such zones.
Claim 7
Dependent Claim
39 words
A device according to claim 5, wherein said alarm means comprises a smoke alarm and a heat or flame alarm, which are accommodated in the common protective housing and operatively connected over said monitored line to such central station.
Claim 8
Dependent Claim
43 words
A device according to claim 5, wherein an additional extinguisher outlet head also is provided, the protective housing being of a size to also operatively support such additional extinguisher outlet head, as well as piping operatively connecting such additional head and said valve.
Claim 9
Dependent Claim
43 words
A device according to claim 2, wherein an additional extinguisher outlet head also is provided, the protective housing being of a size to also operatively support such additional extinguisher outlet head, as well as piping operatively connecting such additional head and said valve.
Claim 10
Dependent Claim
81 words
A device according to claim 2, wherein said control means comprises means responsive to the actuation of said smoke detector to initially open said valve, and timing means operative to effect, in the absence of interim actuation of the flame or fire detector, a closing of said valve after a predetermined time period, and to place said valve under the sole control of the flame or fire detector whereby the latter thereafter determines the open or closed state of said valve.
