technical description

Orcadesair intake openingframe

Fire class Launching mechanism complies to the NFS 61-937

according to the tests of the CNPP relative to the launchingmechanisms for remote controlled opening in front.

Dimensions

advantagesCareful design (grille Cyclades for interior face option).

Good thermal isolation for a maximum comfort.

Good air and waterproofness (covering vanes).

Installation possible on door (with kit).

Motorizable by electrical jack (factory or on work site).

Launching by pneumatic jack.

range Air intake wall opening frames with free area, matching to the

dampers for the corridors.

Wall opening frames of 1m2 of free area or of SGO

for stairwells. 2 versions :

- Insulated.- Insulated : enabling to get a cfcientK = 1,55 W/m2/ C.

Dimensions : range enabling free passing from 10 dm2 to 1 m2(see selection chart).

Launching by electromagnetic jack by pulse or break 24or 48 Vcc or by pneumatic launching.Possibility of double launching by adding a thermal fusecalibrated at 70 C depending on implantation.

Bipolar or unipolar contacts.

application Remote controlled grilles used on vertical face of building,

for natural air intake, of smoke extraction process in ERP andcollective housing (premises, stairwells, corridors).

construction / composition

Grille with articulated vanes, made of aluminium frame inwhich aluminium blades pivot.

The standard nish is anodised natural silver (paint option).

The blades are synchronised by a linkage and opened by a spring.They will be kept closed in position.

The water proofness and airtightness is ensured by the coveringof the vanes. In the insulated version, the airtightness is reinforced

by a gasket. In the insulated version, the blades are doubled with an expanded

polystyrene M1 (K = 1,55 W/m2/C) of 23 mm, locked up in to aPVC case.

Launching deviced :

The facade wall opening frame Orcades is equipped with anelectromagnetic magnet ensuring the launching by pulse or bybreak 24 Vcc or 48 Vcc (power 3,5 W or 1,6 W).

The launching can also be done by pneumatic jack.

It is equipped with a manual rearmament control. It can be equipped with a double launching by adding

a thermal fuse calibrated at 70 C.

options Electric rearmament jack.

Bipolar contacts.

Thermal fuse (double launching fuse and coil).

Assembly kit for thin wall : door and exterior woodwork.

packaging On pallet.

specications The facade wall opening frame will have articulated vanes in

aluminium and will be perfectly air and water proof in closedposition. The free area will be tested in factory..

Mechanism complying to NF S 61-937.

Type Orcades, France Air brand.

*

* Free movement

The installation of Orcades with a frame is highly recommendedto maintain the rigidity of the set.

tting and connection Functioning principle

Assembled on a facade, in a low part of the premises, Orcades ensures fresh air intake.

Installation advice

The facade wall dampers Orcades are attached to a concretewall (mechanism interior side) with the help of sealing frameor in a metallic wall.

Caution, foresee the clearance of the blades (140 mm)towards the exterior of the building.

Caution, complying to 6 o the appendix A che VIII, allthe elements contributing to the rearmament (handle tomanipulate and hanging system by magnetic coil) have tobe at an inerior height o 3m in regards to the foor.

Connection electric version

Two compression glands are delivered to receive the remote control

and signalling cables.The wiring has to be done according to the opposite diagram.

Connection pneumatic version

Copper pipe 6 mm to link to the Orcades. Service pressure 4 Ps 6 bars.

Selection of the Orcades

All the Orcades are with horizontal blades.

Free area (rearmament manual / rearmament by jack) no difference of SLC between a standard Orcades and an insulated Orcades.

Smoke extraction of stairs

To limit or avoid the stairwells lling up with smoke, they can be, depending on the case, smoke extracted by a natural ushingor a pressurising application in relation to the damaged premises.

The DENFC will be placed on the high part of the stairwell, and an air intake, of equal surface, will be placed at the low part of the cage.The manual control of the smoke extraction system is placed on the stairwell, at the level of the building entrance.
