Code m. Ali Hamid, alarm systems and fire detection
A-purpose my info sysco of the alarm systems and detection of the fire main purpose of these systems is the speed of response to the fire and then convert these early response to the audio and visual signal to alert the individual or individuals in the building, place or relief center or amortization group that there is a fire in its early stages of human and considered greatest fire detector on earth what God has given of auditory senses - touch - smell - taste - in addition to the vision of the mind. It senses a group that can not be met in any detector, but the human in perpetual motion and may not coincide presence in the scene of the fire or be sick or asleep or in a state of mind does not allow him to reveal the fire.
Of course you can not reagents Fire discrimination cause of the fire or assess the severity and therefore may cause false alarms for these reagents to some of the problems which in fact does not reflect the error detection, but may return to the selection of the types of non-appropriate reagents or the distribution my info sysco of random my info sysco for them without this study agreed that the reference audio fire detector must be higher than the audio level prevailing in the region increased by 15 dB in addition to the need for these reagents are designed according to the international standard for standards and under the supervision of a laboratory test known coefficient 0
* Primary: without this stage to watch the smoke or flame until sensation, but what is happening at this stage is to generate the amount of combustion particles result of a process of chemical analysis, the bodies of its size and weight, but difficult to see with the naked eye for the small size of the finite has been growing rapidly this stage or slowly my info sysco over a period of time may not exceed a few minutes and ionization detectors respond to this stage. * Smoky stage: With the continued evolution of the fire are increasing the amount of combustion particles to the extent that can be seen with the naked eye, a so-called in this case (the smoke), but even this stage does not notice any flame or heat, and respond PV reagents for this stage. my info sysco
* Heat stage: At this stage, a large amount of heat and flame, smoke and toxic gases formed and characterized this stage very rapid evolution, which does not take more than a few seconds as well as the transmission of flame stage and converts it into heat stage is usually very quickly, and respond reagents temperature for this stage.
1-normal system System Conventional: is a system that depends on the reagents that are connected to each group on a specific area warning is given to this region through my info sysco which the security man moves in this area and discovered the fire scene. 2-system entitled Addressable System: is a system that depends on the reagents and related to each other in the region set to take the names of places where Detector numbers so that when the fire appears on the control panel shows Release No. Detector and the name of the region and an hour of fire and that these systems depends on :
(1) Control Panel: a control-based system and nutrition in the necessary control efforts and work up to where detectors and alarm bells are running and Alsoerin and bulbs statement. (B) be given an audio alarm and light when the fire occurs with determining occurrence my info sysco area. (C) working with electricity for the city (220 V 50 Hz) and refunded backup batteries operate automatically in case of power failure and the charger charge the batteries when the power returns. D-with the possibility of self-test and give you an audio warning signal in the event of a malfunction in the painting or in any part of the system components, or in the case of a power outage or disconnect the batteries. E-key fitted my info sysco to give an alarm in to evacuate the site. And a set-to with Evacuated "Rplhiat" so as to stop the air conditioning and separate power supply my info sysco devices
(2) reagents combustion products: my info sysco combustion products include reagents hardware called the group reagents Fire Fire Detection has been running this system reagents designed to operate at its reveal one of the four main products of combustion, namely:
A - reagents ionized gases (combustion products are not visible) Ionized Gases Detectors (Invisible Products Of Combustion) is the phenomenon of fire is what is happening from the ionization of particles when subjected to the combustion of these particles dysfunctional equilibrium in the electron my info sysco which makes them tend to steal electrons from other molecules, used reagents my info sysco gases ionized this phenomenon in the operation of this type of reagents.
There sensor in the detector room with a small hole to enter the existing air in the room or place to be protected. There is next to the room slot inside a small amount of radioactive material works to ionize air room Detector There is also inside the detector also two plates power plants, one positively charged my info sysco and the other negative, and no negative plate closer to the source of the radioactive material distance, and works particles ionized by the radioactive material to liberate an electron travels to the positive plate, causing stream flow passes between the plates on an ongoing basis.
When a fire and the entry of fire products ionized my info sysco by the fire inside the detector chamber, where they are dysfunctional balance (ie you need to electrons) is working to capture electrons pedestrians between the plates (which are working on the current flow), leading to the suspension of the current flowing and the launch of warning
B - smoke detectors (visible combustion products) Smoke Detectors my info sysco (Visible-Products - Of - Compustion) are smoke detectors manufactured using photoelectric cell coupled with a particular light source. This cell is a flat disk turns the spotlight it to an electric current. This cell is used to detect smoke in two ways: first: the use of beam Beam. And second, depending on resistance Beam Refractory and dispersed.
The method relies beam shining a beam of light across the area to protect it until it reaches inside the cell Alkahrodoi
