Abstract

<P>PROBLEM TO BE SOLVED: To provide a flexible and relatively compact fire alarm receiver the installation place of which can be changed after installed since it is portable. <P>SOLUTION: A carrying handle 2 which is formed of metal or plastic is provided at an upper end of a fire alarm receiver 1, a terminal table 3 is provided on an outside surface of the fire alarm receiver 1, and a fire alarm or a fire alarm line 4 is connected to the terminal table 3. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a relatively small fire alarm receiver having high flexibility.

  In a commercially available fire alarm facility, a fire detector is usually connected to a terminal block of a fire alarm receiver via a cable (see, for example, Patent Document 1).

  By the way, the conventional fire alarm receiver is considerably large and is fixed at a predetermined position by concrete or the like, and can be easily moved to another position when changing the fire prevention zone, maintaining, or replacing parts. First, when changing the fire prevention zone, it is necessary to purchase another fire alarm receiver. For this reason, conventional fire alarm receivers are not portable and thus lack flexibility and have high maintenance costs.

Therefore, the present invention has been made for the purpose of providing a highly flexible fire alarm receiver.

  According to this invention, the carrying handle is provided at the upper end of the fire alarm receiver, and the terminal block is provided on the outer surface of the fire alarm receiver, and the fire detector or the fire detection line is connected to the terminal block. It is possible.

  Examples of the present invention will be described below, but the present invention is not limited to the following examples.

  1 and 2 show a fire alarm receiver 1 according to the present invention. In the fire alarm receiver 1, a metal or plastic carrying handle 2 having a substantially semicircular or inverted U-shaped side surface is provided at the upper end of the fire alarm receiver 1. Therefore, the handle 2 can be grasped by hand, the fire alarm receiver 1 can be carried and moved to an arbitrary installation location. Further, the terminal block 3 (FIG. 2) is installed in the vertical direction slightly closer to one side on the back outer side surface of the fire alarm receiver 1. A fire detector (not shown) or a fire detection wire 4 can be connected to the terminal block 3. Further, the capped cord 7 (FIG. 2) is connected to an AC power source.

  FIG. 5 or FIG. 6 shows the fire detection line 4, and the fire detection line may be appropriately wound as shown in FIG. 5. Even if the fire detection line 4 is wound around the reel 5 as shown in FIG. Good. Further, as shown in FIG. 6, it is possible to connect the fire detection line 4 and the terminal block 3 via the relay connection line 6. Further, a fire detector may be directly connected to the terminal block 3. The fire detection line 4 is disclosed in International Publication WO2005 / 022478, Japanese Patent No. 3775748, and the like.

  Although not shown, as an example, the fire sensing wire 4 is a pair of long conductors such as a copper wire or an aluminum wire, and one shape memory alloy body of a predetermined length or a predetermined interval is provided around the pair of conductors. Place a plurality. For example, the conductor is housed in a fusible insulator of a pair of fusible insulated wires. This shape memory alloy body has a coil shape, and when the ambient temperature of the shape memory alloy body reaches a set temperature, the shape memory alloy body is restored in shape by the heat.

  When a fire occurs, the ambient temperature rises due to the heat of the fire, and when the temperature reaches the set temperature of the shape memory alloy body, the shape memory alloy body is reconstructed by the heat of the fire at the fire sensing line 4 and the coil The radius of the shape decreases. As a result, both electric wires are contacted or connected by the shape memory alloy body. Therefore, an electric current is supplied from the fire alarm receiver 1 or the like, flows to the fire lamp, etc., and the fire lamp is turned on by the current to give an alarm, so that the fire can be dealt with accurately.

  Further, the cord 9 of the bell member 8 as shown in FIG. 3 or 4 can be connected to the terminal block 3. In FIG. 3 or FIG. 4, the bell member 8 is also of a portable type, similar to the fire alarm receiver 1. In the bell member 8 shown in FIG. 3, the bell member 8 can be suspended by the metal fitting 10. As shown in FIG. 4, the cord 9 may be wound around the reel 11.

  Therefore, a fire can be detected by the fire detection line 4, the bell member 8 can be sounded, and a fire can be alarmed. The bell member 8 can be sounded by the push button 12 to warn of a fire.

  Furthermore, the fire alarm receiver 1 can be moved to an arbitrary installation location, and the bell member 8 can be arbitrarily moved, and its flexibility is high.

It is a perspective view of the fire alarm receiver concerning this invention. It is the perspective view of the fire alarm receiver of FIG. 1 seen from the back surface. It is a perspective view which shows an example of the bell connected to the terminal block of a fire alarm receiver. It is a perspective view which shows the other example of the bell connected to the terminal block of a fire alarm receiver. It is a perspective view which shows an example of the fire detection line connected to the terminal block of a fire alarm receiver. It is a perspective view which shows the other example of the fire detection line connected to the terminal block of a fire alarm receiver.
