The diagram above shows a 殴打/砲列, a switch and a bell. The switch might be nothing more that a 押し進める-button switch. The switch is shown "open", and the bell would not be (犯罪の)一味ing. If the switch were "の近くにd", the bell would (犯罪の)一味. Just in 事例/患者 you are not yet (疑いを)晴らす what you are looking at, I'll 追加する: The 回路・連盟 above would lousy for a 夜盗,押し込み強盗 or 解雇する/砲火/射撃 alarm. It would be good for a doorbell! I 手配中の,お尋ね者 a simple starting point for this help とじ込み/提出する.
The diagram shows the "alarm system" in a "no event" 明言する/公表する, there is no 解雇する/砲火/射撃, there is no 侵入者.
To make our rather sad 回路・連盟 into a usable (though still poor) alarm system, we need to use something "clever" for the switch. Here's where you can spend money, or have fun, or both.
You can buy 装置s which are switches, but which are "switched on" (の近くにd) not by your finger, but by the presence of 解雇する/砲火/射撃 or of a 夜盗,押し込み強盗. Or you can make something that 配達するs the same 機能(する)/行事.... but we're not going to go 負かす/撃墜する that path.
For a 夜盗,押し込み強盗 alarm, it is too susceptible to a 夜盗,押し込み強盗, upon tripping the alarm 簡単に re-開始 the switch, and turning the bell off again.
For a 解雇する/砲火/射撃 alarm, it is unnecessarily unreliable. More on this in a moment.
To 妨害する the 夜盗,押し込み強盗, we are going to want a latching 回路・連盟. Once the bell starts (犯罪の)一味ing, it should continue (犯罪の)一味ing even if the wires around the switch are torn off the 塀で囲む and destroyed... or, alternatively, connected together. One or the other will turn off some 天然のまま alarm systems. 遂行するing the latching is a topic for another time, or for 達成するing by the general techniques 演説(する)/住所d どこかよそで in these sensing and 支配(する)/統制する tutorials. (See, for instance, the pages on programming the systems.)
The page you are reading now concentrates on how the sensors should be 麻薬中毒の up.
The "unnecessary unreliability" of the system is an area which has led to the に引き続いて answers and traditions in the world of alarm systems.
Many 夜盗,押し込み強盗 and 解雇する/砲火/射撃 detectors are, essentially, switches.
伝統的に, 解雇する/砲火/射撃-(悪事,秘密などを)発見するing switches open when they "see" no 解雇する/砲火/射撃, and の近くに when they "see" 解雇する/砲火/射撃. And, somewhat surprisingly?, 夜盗,押し込み強盗-(悪事,秘密などを)発見するing switches operate the other way around.
The に引き続いて shows a fancier alarm system than the one we saw before. It uses 伝統的な detectors. The system is shown with no 解雇する/砲火/射撃, no 夜盗,押し込み強盗 (悪事,秘密などを)発見するd, i.e. with the switches all in their "no event" 明言する/公表するs. (If you are the least bit unfamiliar with the switch symbols used, take a quick peek at my little aside about switch symbols. Clicking that link will open the (警察などへの)密告,告訴(状) in a new window or tab... you won't lose the page you are reading now.)
Wow! Our "simple" little alarm system has grown a bit!
The 詳細(に述べる)s of the 監査役 are beyond the 範囲 of this page. The point of the above is to 許す me to tell you about how 解雇する/砲火/射撃 and 夜盗,押し込み強盗 detectors are 伝統的に connected to alarms. The sort of sensors used in the above are the sort you will be able to buy easily.
解雇する/砲火/射撃 sensors tend to be switches that の近くに when 解雇する/砲火/射撃 is (悪事,秘密などを)発見するd. Some are momentary, and others の近くに for good if they get hot, and have to be 取って代わるd after doing their 職業. 夜盗,押し込み強盗 sensors tend to open when an 侵入者 is (悪事,秘密などを)発見するd. There is a method to this madness, but I will defer that discussion. First let's just look at how it 作品.
The 解雇する/砲火/射撃 sensors, the once connected to "A" and "B". Imagine for a moment there is nothing at the end of the 宙返り飛行, that there is no resistor 示すd "EOL". The 監査役 will 試みる/企てる to send electricity from A, across on of the "rungs" of the ladder of open (while they are 冷淡な) 解雇する/砲火/射撃 sensing switches, and 支援する, somehow, to B. As long as there is no EOL resistor, the 支配する is simple: If no electricity is able to get around the A-B 宙返り飛行, then there is no 解雇する/砲火/射撃.
Now consider the "C-D" 宙返り飛行. That shows three 普通は の近くにd 侵入者 detectors. As drawn, electricity will flow around that 宙返り飛行, and the 監査役 should 解釈する/通訳する that as "no 侵入者".
The switch connected to E and F is the "turn on the 夜盗,押し込み強盗 alarm" switch. The 監査役 will only "look" at the 夜盗,押し込み強盗 sensors if the switch is の近くにd. (推定では, the 解雇する/砲火/射撃 alarm 機能(する)/行事 should always be "on".)
So far, so good, I hope.
We're now going to return to the 解雇する/砲火/射撃 detectors 宙返り飛行, 宙返り飛行 A-B, and consider the 状況/情勢 when the EOL resistor is 現在の, as shown.
"EOL" stands for "end of line". Having an EOL resistor in place means you need a わずかに more 複雑にするd 監査役. Now the 支配するs are....
"Trouble" is a 警告 to the system's owner that all is not 井戸/弁護士席. It is ありそうもない that there is a 解雇する/砲火/射撃.... but it is probable that if there were to be a 解雇する/砲火/射撃, then the alarm would not (犯罪の)一味 as it should.
The point of the EOL resistor, and the extra work creating the more コンビナート/複合体 監査役, was to guard against the very real 可能性 that, over the years, something will happen to 原因(となる) a break in the wiring of 宙返り飛行 A-B. You would never know it was there, さもなければ, would you... until you had a 解雇する/砲火/射撃 and the alarm didn't go off.
This isn't just a theoretical "good idea". It is used in any decent 解雇する/砲火/射撃 alarm system. I, 本人自身で, was saved from relying on a "dead" 解雇する/砲火/射撃 alarm system which would not have 報告(する)/憶測d a 解雇する/砲火/射撃. A "trouble" signal 警報d me to a problem in the wiring of the alarm in my home. (A racoon had chewed through the wires.)
Having the 回路・連盟 保護するd like this is called having a "監督するd" 回路・連盟. A diode is いつかs used instead of a resistor at the end of the line.... a zener diode, usually, I think. Anything that lets some 現在の flow, but いっそう少なく 現在の than one of the 解雇する/砲火/射撃 detectors would pass, will do.
Why are 解雇する/砲火/射撃 sensors 普通は open, and 夜盗,押し込み強盗 sensors 普通は の近くにd? Partly from "we've always done it that way", I 嫌疑者,容疑者/疑う, but also because each has it's プロの/賛成のs and 反対/詐欺s, and each is 会合 a different need.
The 夜盗,押し込み強盗-(悪事,秘密などを)発見するing 宙返り飛行, sensors connected "in series", can always carry a 現在の, and can always 誘発する/引き起こす an alarm if the 宙返り飛行 is broken because is something is wrong... be it an actual 侵入者 or troublesome wiring, you need to 扱う/治療する it as a possible 侵入者. You don't NEED the more コンビナート/複合体 可能性s of the other system.
Two things can be understood by 言及/関連 to the に引き続いて....
1) It is NOT a good idea to 追加する an 付加 "ladder" of 解雇する/砲火/射撃 sensors, as shown above. If you need, say, to have a 始める,決める on the first 床に打ち倒す of your house, and a second 始める,決める on the second 床に打ち倒す, you should still, as far as the "logic" of the thing is 関心d just have one "ladder". That doesn't stop you from having sensors on more than one 床に打ち倒す. Just don't be tempted to "追加する on" bits the way it was done in the diagram.
2) You may 追加する a switch, like the one 示すd "4" to the 夜盗,押し込み強盗 alarm sensor string. It would want to be a 非,不,無-momentary "on/off" switch. Can you see what it would do?
When switch 4 is の近くにd, even if the system is "武装した", and "looking" for 侵入者s, it will not "see" switch 3 open.
Such a switch (switch 4) could be useful. It lets you bypass, or "disconnect" some sections of the system. For example, you might want to be able to 監視する just the downstairs 動議 detectors (numbers 1 and 2) in your home when you are there, but upstairs in bed. At that time, you wouldn't want the 動議 detector in the upstairs hall active. (number 3). On the other 手渡す, when the house was empty, you would open switch 4, and all of the sensors would be 監視するd.
3) (not fully illustrated)... You make things difficult for 夜盗,押し込み強盗s... and halve the cost to the wire you use... if just one wire goes out from the 監査役 at "C", and then one wire comes 支援する to "D" by a (mostly) different 大勝する. If a 夜盗,押し込み強盗 can, thought a broken window, say, get at places 類似の to the two points where switch "4" 大(公)使館員s, the 夜盗,押し込み強盗 can bypass parts of the sensor string, can't he/ she?
Once you learn that most 解雇する/砲火/射撃 detectors are open switches when 冷淡な, and most 夜盗,押し込み強盗 (悪事,秘密などを)発見するing switches are の近くにd when no 侵入者 is "seen", you have the facts you need. The 残り/休憩(する) of the 構成要素 here is ありふれた sense, or things you could work out for yourself. What fun is a 事業/計画(する) with no 範囲 for your ingenuity? However, I hope that 存在 given some of the ideas above was welcome?
