Use
PIP-3AN/Distribution box is intended for use in fire alarm systems (FAS) as part of a cable assembly. It is characterised by straight or angular (90 degrees) laying of the signal line.
Cable assemblies composed of a fire box and a cable with fastening ensure the continuity of electricity supply or signal transmission for the time required to activate and operate fire protection devices. According to DIN 4102-12:1998, PIP-3AN/Distribution boxes are classified in the electrical function maintenance class E90.
Construction
The PIP-3AN/Distribution box consists of two parts: a cover and a base (octagonal shape), which are connected together with two screws. The PIP-3AN/Distribution box allows you to connect and branch cables with 4 cores, cross-section up to and including 4 mm2. It has 3 entries enabling the introduction of a cable with a diameter of 7-19 mm and 2 entries (from the ground side) enabling the introduction of a cable with a maximum diameter of 10 mm.
The PIP-3AN/Distribution box is made of sheet metal covered with red powder paint. The side walls of the base have graduated chokes inserted from the top and made of flame-retardant material. Gradation allows you to adjust the hole to the required cable diameter (7-19 mm). Six ceramic cubes with 2 current paths (terminals) each are attached directly to the base of the box. Access to internal connections is limited by a metal cover. There is an embossment under the ceramic cubes, which is intended to increase the mechanical strength of the box during a fire, as well as to equalize the height of the inserted cable with the clamps of the ceramic cubes. The box has separate terminals for connecting the signal line input, separate ones for connecting the signal line output and separate ones for line branching (90°). The base of the box also has a place for grounding connection, mounting holes and chokes made of flame-retardant material enabling the introduction of cables (10 mm) from the ground side.
Operating design
The main task of the PIP-3AN/Distribution boxes is to maintain the continuity of electricity supply or signal transmission in fire conditions (maintaining line continuity).
Opening
To open the box, unscrew the screws in the cover (the screws are equipped with special rubber washers that prevent them from falling out of the cover after unscrewing). Then slide the cover and base apart.
Closing
To close the box, align the base and cover and then tighten the screws.
Assembly recommendations
Mounting holes located in the base of the box enable mounting to the wall or ceiling using steel expansion sleeves and mounting screws. The installation of PIP-3AN/Distribution boxes should be performed in accordance with the provisions included in the National Technical Assessment issued for the product by CNBOP-PIB.
Additional information
There is also a "with fuse" versions available (PIP-3AN/0,75A, PIP-3AN/1,25A), which is identical in structure and connection options to the PIP-3AN/Distribution box, the only difference is an additional fuses that allows you to protect two wires.
On request, it is possible to make the box in white. The feasibility and cost of execution are confirmed by an individual offer upon request, which should include the color of the box.
If you need to purchase additional screws/washers to mount the cover, two sets are available:
- Set 1 – for boxes PIP-1AN, PIP-2AN, PIP-2AN/Distribution/3conductors/4mm2, PIP-2AN/Junction/6x4mm2, PIP-2AN/Junction/9x4mm2, PIP-3AN, PIP-5A, PIP-7A
- Set 2 – for boxes PIP-2AN/Distribution/3conductors/6mm2, PIP-2AN/Junction/9x6mm2
Each set includes a set of elements for mounting covers on 10 pieces of boxes.
Additionally, it is possible to purchase rubber-grommet separately.
It is not allowed to make any changes to the box structure by third parties (e.g. replacing the fuse). Any modifications result in the loss of the manufacturer's warranty and invalidation of the documents issued by CNBOP-PIB.
Detailed information are available in the Operation and Maintenance Manual (O&M) of the product.
