FDAS | Areas where detection is required

 


These are areas or spaces where detection is required.

♦ The spaces under raised floor more than 600mm in height. If conventional detection are used, they should be wired as a separate alarm zone.

♦ The spaces above drop ceiling more than 1 meter in height. If conventional detection are used, they should be wired as a separate alarm zone.

♦ Concealed spaces under the roof more than 1 meter in height. If conventional detectors are used, they should be wired as a separate alarm zone.

♦ Stairwells, with detection at each floor level.

♦ Return air ducts of air conditioning system using sampling tubes.

♦ Tunnels linking two or more buildings.

♦ Vaults or the like.

♦ Vertical shafts.

In places of assembly, the stage and enclosed platform used in occupancy.

The Enclosed Platform, is a partially enclosed portion of an assembly room the ceiling of which is not more than one hundred fifty five centimeters (155cm) above the proscenium opening of which is designed or used for the presentation of plays, demonstrations, or other entertainment wherein scenery, drops, decorations or other effects be installed or used.

The Stage, is partially enclosed portion of an assembly building which is designed or used for the presentation of plays, demonstrations, or other entertainment wherein scenery, drops or other effects may be installed or used, and where the distance between the top of the proscenium opening and the ceiling above the stage in more than one hundred fifty two centimeters (152 cm).

The Trust Stage, refers to the portion of the platform open on at least  three (3) sides to audience seating. It may be with or without  overhead scene handling facilities.

The Arena Stage, is a stage of a platform open on at least (3) sides to an audience seating. It may be with or without overhead scene handling facilities.

Why do the Philippines have slow internet?

Image
  It isn't that the country's regulatory landscape makes it difficult for internet service providers to put up the necessary infrastructure.  Actually the approval of electronics systems designs and plans in the city and municipal areas isn't difficult, it was most likely because they could not enforce the law. And also corrupt government officials exploit this lack of enforcement to steal money from the telecommunication companies. The Department of Interior and Local Government (DILG), Department of Public Works and Highways (DPWH), Department of Information and Communications Technology (DICT), has released memorandum circulars on RA 9292, Electronics Engineering Law of 2004 regarding its implementation. The Local Government Units should already have a guide in formulating a unified and defined set of procedures in the releasing electronics permit and in the checking and approving of electronics system plans and designs. The country's regulatory landscape NEVER make...

The Distributed Antenna System

A distributed antenna system is most often used to distribute cellular network coverage to heavily populated buildings, such as offices, high-rise apartments, shopping centers or sports stadiums. The Telecommunication facility is one of the major parts of the building utility to provide communications. The building owner shall provide space to house the telecommunication facility of the building. The distributed antenna system is part of the telecommunication facility of the building. The distributed antenna system, is an in-building solution comprising of a number of pico cells to provide wireless coverage and services using 2G. 3G, 4G, 5G, and even 6G wireless access technology. Definite number of antennas constitutes one single sector; this means that these set of antennas are strategically installed inside a building / compoun...

An electronic engineer in the renewable energy sector

Photo Credits | Camila Fernández León Renewable energy are natural and self-replenishing, and usually have a low- or zero-carbon footprint. Examples of renewable energy sources include wind power, solar power, bio-energy (organic matter burned as a fuel) and hydroelectric, including tidal energy.  Renewable energy engineers develop and design systems to use energy from renewable resources, such as the sun, wind, and water. Renewable resources are energy sources that are naturally and continually replaced. They are alternatives to nonrenewable resources such as coal, oil, and natural gas that do not replenish themselves, and are environmentally destructive. It's crucial to gain specialized expertise. Focus on understanding the electronic components that are vital for renewable energy systems, such as inverters, which convert direct current (DC) from solar panels into alternating current (AC) for use in homes and businesses. Familiarize yourself with energy storage systems, ...
