Abacus 6 Engineer Manual
Cristoforo Kanoy
I have just moved into a property that has an abacus 6/14 alarm system installed, but no manuals, I am a Texecom approved installer, but don't fit alarms anymore, I have the user code, but not the engineer code, I would like to reset this system and start from scratch as I al;so need to remove a blown up door alarm from it, can anyone PM me with the installer manual please?
If anyone can PM me the installer manual that would be great, at the moment I cant set the alarm as the entry sensor is defunct (installed by the previous owners in a place where rainwater can get to it
I can't think of an easy way to do it without the installer manual, I tried to let the system drain last weekend, but had to reapply the power after the external sounder activated (11 oclock at night) but I lost the control panel due to low voltage so could not reset it, also I think the settings are in Non Volatile Memory (there are two NVM chips on the main borad) so I'm not even sure a power down would factory default it. I only have a user code so cannot add or delete wireless sensors which is what I need to do as the main entry/exit door sensor (mounted so that rainwater can get in) has blown up due to water content within, also I would like to connect a BT line to it which I think is possible but again without the installer manual is difficult
Being a Texecom approved installer doesn't neccessarilly mean you will be accepted as a trade member on these forums. If you are in the trade then please read the following page and then complete the form.
I've just moved into a house with an Abacus 8 alarm panel, the previous owners didn't have a code for the unit and therefore neither do i. Is there any way to either find the code or reset it? I could also do with a manual if possible
Any other advice would be useful, i'm not trained directly in alarm systems but have extensive experience and training in industrial electrical and electronic systems so i'm not too worried about swapping the panel over if required.
but there are much better systems available now, i would recommend the Gardtec 490x, very good with a built in dialler which will contact any 4 numbers you like whrn the alarm goes off, and much more.
this is a nice little panel, we used to fit loads. its not difficult for a qualified engineer to make it do what you want. probably 1-2 hours work, based on what you have said you need done (depends on cable run to front door too). when you power it up, what does it say after 10 seconds or so?
my dear friend this is not a help you do it yourself site .the only advise given is get an alarm guy and pay up. i think your box needs to be defaulted and reprogramed with new key codes .i have the same problem but nobody will help.i will probley be cast out for saying this but if you read the rules carefully you will see what i mean.
if by alarm guy you mean someone with the training, ability, tools and insurance then your probably right but please it isnt a conspiracy or a secret club it`s usually insurance lead and it`s like that for your protection
An abacus (pl.: abaci or abacuses), also called a counting frame, is a hand-operated calculating tool which was used from ancient times in the ancient Near East, Europe, China, and Russia, until the adoption of the Arabic numeral system.[1] An abacus consists of a two-dimensional array of slidable beads (or similar objects). In their earliest designs, the beads could be loose on a flat surface or sliding in grooves. Later the beads were made to slide on rods and built into a frame, allowing faster manipulation.
Any particular abacus design supports multiple methods to perform calculations, including addition, subtraction, multiplication, division, and square and cube roots. The beads are first arranged to represent a number, then are manipulated to perform a mathematical operation with another number, and their final position can be read as the result (or can be used as the starting number for subsequent operations).
In the ancient world, abacuses were a practical calculating tool. Although calculators and computers are commonly used today instead of abacuses, abacuses remain in everyday use in some countries. The abacus has an advantage of not requiring a writing implement and paper (needed for algorism) or an electric power source. Merchants, traders, and clerks in some parts of Eastern Europe, Russia, China, and Africa use abacuses. The abacus remains in common use as a scoring system in non-electronic table games. Others may use an abacus due to visual impairment that prevents the use of a calculator.[1] The abacus is still used to teach the fundamentals of mathematics to children in most countries.[citation needed]
Some scholars point to a character in Babylonian cuneiform that may have been derived from a representation of the abacus.[12] It is the belief of Old Babylonian[13] scholars, such as Ettore Carruccio, that Old Babylonians "seem to have used the abacus for the operations of addition and subtraction; however, this primitive device proved difficult to use for more complex calculations".[14]
Greek historian Herodotus mentioned the abacus in Ancient Egypt. He wrote that the Egyptians manipulated the pebbles from right to left, opposite in direction to the Greek left-to-right method. Archaeologists have found ancient disks of various sizes that are thought to have been used as counters. However, wall depictions of this instrument are yet to be discovered.[15]
A tablet found on the Greek island Salamis in 1846 AD (the Salamis Tablet) dates to 300 BC, making it the oldest counting board discovered so far. It is a slab of white marble 149 cm (59 in) in length, 75 cm (30 in) wide, and 4.5 cm (2 in) thick, on which are 5 groups of markings. In the tablet's center is a set of 5 parallel lines equally divided by a vertical line, capped with a semicircle at the intersection of the bottom-most horizontal line and the single vertical line. Below these lines is a wide space with a horizontal crack dividing it. Below this crack is another group of eleven parallel lines, again divided into two sections by a line perpendicular to them, but with the semicircle at the top of the intersection; the third, sixth and ninth of these lines are marked with a cross where they intersect with the vertical line.[20] Also from this time frame, the Darius Vase was unearthed in 1851. It was covered with pictures, including a "treasurer" holding a wax tablet in one hand while manipulating counters on a table with the other.[18]
The normal method of calculation in ancient Rome, as in Greece, was by moving counters on a smooth table. Originally pebbles (Latin: calculi) were used. Marked lines indicated units, fives, tens, etc. as in the Roman numeral system.
One example of archaeological evidence of the Roman abacus, shown nearby in reconstruction, dates to the 1st century AD. It has eight long grooves containing up to five beads in each and eight shorter grooves having either one or no beads in each. The groove marked I indicates units, X tens, and so on up to millions. The beads in the shorter grooves denote fives (five units, five tens, etc.) resembling a bi-quinary coded decimal system related to the Roman numerals. The short grooves on the right may have been used for marking Roman "ounces" (i.e. fractions).
The Roman system of 'counter casting' was used widely in medieval Europe, and persisted in limited use into the nineteenth century.[22] Wealthy abacists used decorative minted counters, called jetons.
Due to Pope Sylvester II's reintroduction of the abacus with modifications, it became widely used in Europe again during the 11th century[23][24] It used beads on wires, unlike the traditional Roman counting boards, which meant the abacus could be used much faster and was more easily moved.[25]
The Chinese abacus, also known as the suanpan (算盤/算盘, lit. "calculating tray"), comes in various lengths and widths, depending on the operator. It usually has more than seven rods. There are two beads on each rod in the upper deck and five beads each in the bottom one, to represent numbers in a bi-quinary coded decimal-like system. The beads are usually rounded and made of hardwood. The beads are counted by moving them up or down towards the beam; beads moved toward the beam are counted, while those moved away from it are not.[27] One of the top beads is 5, while one of the bottom beads is 1. Each rod has a number under it, showing the place value. The suanpan can be reset to the starting position instantly by a quick movement along the horizontal axis to spin all the beads away from the horizontal beam at the center.
