Description
【考案の詳細な説明】 この考案は火災感知器に関するものである。[Detailed explanation of the idea] This invention relates to a fire detector.
自火報用感知器から自主設置の受信機を制御す
るため、自火報回路とは電気的に絶縁された外部
出力接点をもつとともに確認灯の付いた従来の感
知器の回路例を第１図に示す。Ａは感知器接点、
Ｂはリレー、Ｃは確認灯回路、a1は保持接点、a2
は外部出力接点、Ｄは自火報回路の受信機側Ｋの
リレーである。そして、感知器接点Ａがオン動作
すると、リレーＢおよび確認灯回路Ｃに通電さ
れ、リレーＢが働いて保持接点a1および外部出力
接点a2が閉じる。 In order to control a self-installed receiver from a self-fire alarm sensor, the first example is a conventional sensor circuit that has an external output contact that is electrically isolated from the self-fire alarm circuit and is equipped with a confirmation light. As shown in the figure. A is the sensor contact,
B is a relay, C is a confirmation light circuit, a 1 is a holding contact, a 2
is an external output contact, and D is a relay on the receiver side K of the self-fire alarm circuit. When sensor contact A turns on, relay B and confirmation light circuit C are energized, and relay B operates to close holding contact a1 and external output contact a2 .
しかしながら、この回路構成は、受信機側Ｋの
電源でリレーＤ，Ｂを同時に動作させなくてはな
らないが、受信機電圧が下がつた場合を考慮する
と、リレーＢは小電力で動作する高感度なものが
要求されるという問題がある。また確認灯回路Ｃ
を有するため、リレーＢに流れる電流はさらに減
り、リレーＢの選択がさらに限られたものとな
り、コスト的にも数量的にも不利になる。 However, with this circuit configuration, relays D and B must be operated at the same time by the power supply on the receiver side K, but considering the case where the receiver voltage drops, relay B is highly sensitive and operates with low power. The problem is that things are required. Also, confirmation light circuit C
Therefore, the current flowing through relay B is further reduced, and the selection of relay B is further limited, which is disadvantageous in terms of cost and quantity.
したがつて、この考案の目的は、コスト的に有
利でしかもより確実に動作できる火災感知器を提
供することである。 Therefore, the object of this invention is to provide a fire detector that is cost-effective and can operate more reliably.

ある。 An embodiment of this invention is shown in FIG. That is, this fire detector has a series circuit of a relay 2 and a sensor contact 3 on the detector side 1, and a series circuit of a confirmation light circuit 4 for operation confirmation and a holding contact 5 of the relay 2 as shown in the figure. are connected in parallel, and a diode 6 is connected between the first connection point 11 and the second connection point 12 of both series circuits so that the confirmation light circuit 4 side becomes the cathode side. 7 is an external output contact of the relay 2. Further, on the receiver side 8, 9 is a control relay, and 10 is a line connecting the receiver side and the sensor side.
この火災感知器は、感知器の動作により感知器
接点３が閉じると、リレー２が通電されるが、確
認灯回路４はダイオード６により阻止されるので
電流は流れない。つぎにリレー２が働いて保持接
点５が閉じると確認灯回路４に電流が流れ動作を
開始する。外部出力接点７はリレー２の動作によ
つて閉じる。 In this fire detector, when the detector contact 3 is closed due to the operation of the detector, the relay 2 is energized, but the confirmation light circuit 4 is blocked by the diode 6, so no current flows. Next, when the relay 2 operates and the holding contact 5 closes, current flows to the confirmation light circuit 4 and the operation starts. The external output contact 7 is closed by the operation of the relay 2.
このように構成したため、リレー２の感動時に
は確認灯回路４には電流が流れないので従来に比
べて余分に電流が流れることになり、このためリ
レー２の感動電流の選択幅が広がり、リレー単価
が下がることとなる。またリレー２の感動がより
確実となり信頼性の高い感知器ができる。なお、
リレーの復旧は感動電流に比べて少ないため、確
認灯回路４に電流が流れてもリレー２が復旧する
ことがないことは言うまでもない。 With this configuration, when the relay 2 is impressed, no current flows through the confirmation light circuit 4, so an extra current flows compared to the conventional case.This expands the selection range of the touching current for the relay 2, and reduces the relay unit price. will decrease. In addition, the relay 2 is more reliable, making it possible to create a highly reliable sensor. In addition,
It goes without saying that the relay 2 will not be restored even if current flows through the confirmation light circuit 4, since the recovery of the relay is less than that of the moving current.
