It has become.

However, in order to transmit this detected M-red to the next-stage i1 alarm device such as a lamp installed in a central monitoring station, etc., if the conventional smoke detector is directly connected to the i1 device, the smoke This alarm device also operates when the amount of smoke in the smoke pond is low, and the central monitoring station can immediately tell whether smoke has been detected due to a fire, etc., or if the life of the smoke pond has reached the end. Is it necessary to go to the place where the smoke detector is installed and check? 0, it will complicate the monitoring work and there is a risk that a fire will break out and make the fire bigger.

(Purpose of the Invention The object of the invention is to provide a smoke detector having a low battery capacity alarm function with a signal transfer terminal circuit that does not operate when the battery is low. Only at the time of detection, the detection result is transmitted to the next stage alarm device, so that the occurrence of a fire can be quickly and accurately known through mid-air monitoring, etc. The purpose is to

B) Structure of the Invention The smoke detector with a transfer terminal of the present invention is an electric power source, and the smoke detection state 'f' is notified by a continuous signal, and the bundle state of the battery capacity M# is notified by a pulse number 1S. Short model, groove, this notification output is O
The notification output is continuous when integrated by the R-type integration circuit.
It is characterized by having a transfer terminal circuit that closes the transfer terminal only when the pulse information is n. When the signal is integrated, the J:D transfer terminal movable level is not reached, and therefore the transfer terminal is closed.

(E) Embodiment 2 Figure 2 shows a schematic diagram of an embodiment of the smoke detector with S-signal terminal of the present invention, and parts similar to those in the example in the same area are designated by the same numbers and their explanations will be omitted.

On the other hand, the highest level ( Since OX) is above this activation sensitivity level (e)F, the relay ring for the transfer terminal is activated every 18g of smoke detection, and the transfer terminal (2) (24 is closed. Therefore, fire etc. Detects the occurrence of smoke and outputs a penalty signal. Only the smoke detection signal is actuated to close the transfer terminals 1221 and 4, and the next stage alarm bag is activated accurately. It is something that makes you

(F) Effects of the Invention Therefore, even if the present invention has a battery reduction alarm function, the transfer terminal circuit transmits the detection result directly to the next stage alarm bag only when smoke is detected, so medium fire monitoring is possible. It is possible to obtain a smoke detector with a transfer terminal that can quickly and accurately detect the occurrence of a fire in a cave, etc., and is highly effective in extinguishing a fire in its early stages.
