RKAS's technical requirements for schools.
Also is taken into account: contractor-, architectural- and client requirements for the building, the
building architectural solution, function of rooms, construction, indoor climate, design and furnishings;
mounting spaceof the firing.
Properties of the automatic fire alarm systems components must comply with the European standard.
The contractor who installs these systems (the contractor) must be qualified, have a corresponding
certificate and must use skilled labor.
Low-current contractor is responsible for ensuring that buildings are built in accordance with the
project, what is based on normative documents and instructions of installation. Contractor must verify
and ensure that his own and all his subcontractors installed equipment and materials are appropriate
and meet the Estonian safety and quality requirements, also it must have EU-certificate.
Equipment and materials requested in this design can be replaced only by the materials that have the
same technical parameters, but only by the written approval of the designer and the client.
Installation components, materials and appliances that are non-standard and do not comply with
standard documents, are forbidden to use in this project!
Changes that the contractor makes during construction must be coordinated by the contracting
authority and designers. If the contractor replaces equipment with other so that it leads to a change in
the project, the Contractor shall cover the related costs.
Non-adherence to the project and making modifications without coordinating with the project designer,
electrical and fire-based accidents are considered as a fault of the contractor.
Hidden work acts must be done when hidden works are taking place, these acts must be included in
operational documentation.
1.3 Cabling
Type of cables, number of lines and cross-sections, mounting and montage instructions are included to
layouts, schemes and material specification tables. Supply and installation of the cabling are included to
this contract.
Cabling is installed, depending to the usage of the rooms, -environmental conditions and -construction,
so that accidental damage to it is excluded.
Preferably, cables are installed as hidden. In facilities cables are installed on surface, inside of the plastic
protection pipes or cabling ladders.
Low- and strong-current power cables are installed on the cabling ladders so, that the gap between
them is minimally 100mm, or the ladders are isolated with plates so, that the low- and strong-current
cables are separated from one another.
The required separation inside the floor cabling channels and in the distribution boxes are achieved with
placing isolation between the cables. When using rigid or flexible cable protection pipes strong and lowcurrent cabling are always separated.
All cabling, including separate cables and groups, are installed parallel to the main axis of the building.
Free cabling are protected where needed (floor penetrations, wall penetrations, etc.) with strong steel,
or PVC- installation pipes ( according to wall type).
Transferring from one fireproof zone to another, penetrations must be sealed with good quality fire-,
gas-, and moisture proof silicone foam.
Installed cables and wiring are labeled on both ends with weather-resistant cabling marks, according to
the cable listings.
Type of cables, number of lines and cross-sections, mounting and montage instructions are included to
layouts, schemes and material specification tables. Supply and installation of the cabling are included to
the subcontract of the low-current systems .
