Description

[[Technical Field]]

[0001] The present invention relates to a fire receiver provided with a zone display unit that displays a location where an abnormality has occurred. [[Background Art]]

[0002] Conventionally, fire receivers such as fire receivers or display devices are provided with a zone display unit that displays a location where a fire or other abnormality has occurred. For example, Patent Document 1 discloses a fire receiver provided with a zone display unit that includes a zone window sheet having front and back surfaces formed with different appearances. In Patent Document 1, characters indicating a zone are displayed by engraving or the like on a transparent plate superimposed on the zone window sheet, a paper piece sandwiched between the zone window sheet and the transparent plate, or the zone window sheet.

[0003] [[Patent Document 1]] Japanese Unexamined Patent Publication No. Hei 07-249184 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] In Patent Document 1, the zone window sheet whose front and back surfaces are formed with different appearances makes it easy for a user to identify the type of line for each zone indicator lamp. Regarding characters indicating the zone where a line is installed, Patent Document 1 discloses a mode of displaying characters by engraving or the like on a transparent plate or a zone window sheet. However, engraving characters requires special equipment, and when changing the displayed characters, a request to a specialized contractor is required, which incurs cost and time. Further, in the mode described in Patent Document 1, in which characters are displayed on a paper piece sandwiched between a zone window sheet and a transparent plate, writing characters on the paper piece is easy and does not require special equipment. However, in addition to the paper piece, the zone window sheet and the transparent plate are also required, which increases the number of members related to zone display and thereby increases the cost.

[0005] This invention was made against the backdrop of the above-mentioned problems, and aims to provide a fire alarm receiver equipped with a district display unit that makes it easy to identify the type of line, while suppressing the cost associated with changing the characters. [Means for solving the problem]

[0006] The fire alarm receiver according to the present invention comprises a housing and a district indicator unit provided on the surface of the housing for indicating the location where an abnormality has occurred. The district indicator unit comprises a plurality of indicator lights, a plurality of display sheets provided corresponding to each of the plurality of indicator lights for indicating the district name, and a plurality of covers attached to the housing and superimposed on each of the plurality of display sheets. Each of the plurality of covers comprises a substrate made of a light-transmitting material, a first region provided on a part of one surface of the substrate and having opaque properties, and a second region provided on a part of the other surface of the substrate, having opaque properties and having a different appearance from the first region. [Effects of the Invention]

[0007] The fire alarm receiver of the present invention has a cover that is superimposed on multiple display sheets showing district names. The cover is made of a light-transmitting material and has a base material on both sides that is opaque to light and has a different appearance from the other two regions. Therefore, by superimposing a region of the base material made of light-transmitting material that is different from the first and second regions onto the characters on the display sheet, the characters can be made visible, and the characters on the display sheet can be easily changed by reprinting or rewriting them. In addition, because the first and second regions on both sides of the cover have different appearances, the type of circuit can be easily identified by changing the orientation in which the cover is attached depending on the circuit. [Brief explanation of the drawing]

[0008] [Figure 1] This figure shows the external appearance of a fire alarm receiver according to an embodiment. [Figure 2] This is a diagram illustrating the district display unit according to an embodiment. [Figure 3]This is a diagram illustrating a cover according to an embodiment. [Figure 4] This figure illustrates another example of a cover according to the embodiment. [Modes for carrying out the invention]

[0009] The present invention is not limited to the following embodiments and illustrated forms, and can be modified in various ways without departing from the spirit of the invention. Furthermore, the present invention includes all possible combinations of the configurations shown in the following embodiments. Also, in each figure, parts denoted by the same reference numerals are the same or equivalent, and this is common throughout the entire specification.

[0010] Embodiment. (Configuration of fire alarm receiver) Figure 1 is a diagram illustrating the external appearance of a fire alarm receiver 1 according to an embodiment. The fire alarm receiver 1 is connected to a detector line and an alarm transmission line (not shown). When a fire detector connected to the detector line receives an alarm signal from a fire, it issues an alarm and also synchronizes smoke control equipment, etc., connected to the alarm transmission line. The fire alarm receiver 1 comprises a housing 2, a district display unit 3, and an operation unit 4.

[0011] The housing 2 is made of metal plates and has a space inside for housing components. The front of the housing 2 is made of a door that can be opened and closed, and the components inside the housing 2 can be seen by opening the door. In this embodiment, the area display unit 3 and the operation unit 4 are provided on the surface of the door of the housing 2, and the area display unit 3 and the operation unit 4 can be seen without opening the door.

[0012] Multiple area display units 3 are arranged in a row on the front of the housing 2. Each of the area display units 3 is associated with either a detector line or an alarm transmission line to which the fire alarm receiver 1 is connected, and displays the status of the associated detector line or alarm transmission line. Specifically, when an area display unit 3 associated with a detector line receives an alarm signal or other abnormality detection signal from a device such as a fire detector connected to that detector line, its display state changes, thereby displaying the location where a fire or other abnormality has occurred (i.e., the detector line). Similarly, when a smoke control device connected to an alarm transmission line is activated, the display state of an area display unit 3 associated with an alarm transmission line changes, thereby displaying the location where an abnormality has occurred and the smoke control device is operating.

[0013] The operation unit 4 includes either hardware buttons provided on the housing 2 of the fire alarm receiver 1, or a touch panel superimposed on a display screen such as an LCD screen, or both. The operation unit 4 receives operations from the user and sends signals corresponding to the operations to the control unit of the fire alarm receiver 1 (not shown).

[0014] Figure 2 is a diagram illustrating the district display unit 3 according to an embodiment. Figure 2(A) is a perspective view of the district display unit 3, and Figure 2(B) is an exploded perspective view of the district display unit 3. The surface of the housing 2 is provided with a display window 20, which is a recess or hole in which the district display unit 3 is installed. In this embodiment, the display window 20 is a recess that is recessed in relation to the surface of the housing 2, and the district display unit 3 is provided in this recess.

[0015] The area display unit 3 comprises an indicator light 30, a display sheet 31, and a cover 32. The indicator light 30 is an LED (Light Emitting Diode) or another light-emitting element, which is normally off and lights up in the event of an abnormality such as a fire or when smoke control equipment is operating. In this embodiment, the indicator light 30 is embedded in the display window 20 and emits light from the front of the display window 20. The indicator light 30 may emit light in different colors depending on the type of circuit connected to the corresponding area display unit 3. For example, the indicator light 30 is composed of a single light-emitting element whose emission color can be changed, and the emission color may differ depending on whether the area display unit 3 is connected to a sensor circuit or an alarm transmission circuit. Alternatively, the indicator light 30 may comprise multiple light-emitting elements that emit light in different colors, and the light-emitting element that emits light may differ depending on whether the area display unit 3 is connected to a sensor circuit or an alarm transmission circuit. By switching the state of switches provided on each area display unit 3, it is possible to set whether the area display unit 3 is connected to a sensor circuit or an alarm transmission circuit.

[0016] The display sheet 31 is made of any material such as paper or synthetic resin and is inserted into the display window 20. Preferably, the display sheet 31 is made of a material on which text can be written with a writing instrument or a material on which it can be printed with a general-purpose printer. The display sheet 31 is inserted into the display window 20 in a position that does not overlap with the indicator light 30.

[0017] The cover 32 is a component that is placed on top of the indicator light 30 and the display sheet 31 to cover them. The cover 32 is fitted into the display window 20. The cover 32 may be provided with protrusions (not shown), and the display window 20 may be provided with recesses corresponding to these protrusions, so that the cover 32 can be fixed to the display window 20 by inserting the protrusions of the cover 32 into the recesses of the display window 20. In the example in Figure 2, a configuration is shown in which protrusions having such a function are provided at the left and right ends of the cover 32.

[0018] FIG. 3 is a diagram for explaining the cover 32 according to the embodiment. FIG. 3(A) shows one surface of the cover 32, and FIG. 3(B) shows the other surface of the cover 32. The cover 32 includes a base material 320, a first region 321 provided on one surface of the base material 320, and a second region 322 provided on the other surface of the base material 320.

[0019] The base material 320 is formed of a light-transmitting material, which is a light-permeable material such as a synthetic resin, for example. Since the base material 320 is formed of a light-transmitting material, when the base material 320 is overlapped on the display sheet 31 as shown in FIG. 2(A), characters written on the display sheet 31 are visible through the base material 320.

[0020] The first region 321 and the second region 322 are light-impermeable regions having the property of not transmitting light. For example, the first region 321 and the second region 322 are formed by applying light-impermeable ink or paint to the surface of the base material 320, or by attaching a light-impermeable sheet to the base material 320. The first region 321 and the second region 322 are provided at positions that do not overlap with the indicator light 30 shown in FIG. 2 when the cover 32 is installed on the display window 20. In the example of FIG. 3, the first region 321 and the second region 322 are provided at positions surrounding the indicator light 30. An indicator light window 323 free of light-impermeable material is provided at the center of the first region 321 and the second region 322, and the indicator light 30 is visible through the indicator light window 323.

[0021] The first region 321 and the second region 322 have different appearances from each other. For example, the first region 321 and the second region 322 differ from each other in one or more of color, pattern, and region shape. In the example of FIG. 3, the first region 321 and the second region 322 have the same square frame shape, and differ in either or both of color and pattern. Note that, in general, a zone display associated with a detector line is white, and a zone display associated with an alarm transmission line is yellow, so it is preferable that the first region 321 is white and the second region 322 is yellow.

[0022] Furthermore, the first region 321, the second region 322, and the substrate 320 may be provided with a protective layer, which is a resin coating or sheet, to protect their surfaces. By making the protective layer out of a light-transmitting material, the visibility of the indicator light 30 and the indicator sheet 31, which are visible through the first region 321, the second region 322, and the substrate 320, is not obstructed.

[0023] Figure 4 illustrates another example of the cover 32 according to the embodiment. Figure 4(A) shows one surface of the cover 32, and Figure 4(B) shows the other surface of the cover 32. The cover 32 shown in Figure 4 differs from that in Figure 3 in the shape of the first region 321A and the second region 322A. In addition to surrounding the indicator light 30, the first region 321A and the second region 322A are provided in a frame-like manner on the outer periphery of the base material 320. By increasing the area of ​​the first region 321A and the second region 322A compared to Figure 3, it becomes easier to identify the type of circuit associated with the district indicator unit 3.

[0024] As described above, the fire alarm receiver 1 of this embodiment comprises a housing 2 and a district indicator unit 3 provided on the surface of the housing 2 to display the location where an abnormality has occurred. The district indicator unit 3 comprises a plurality of indicator lights 30 arranged in a row on the surface of the housing 2, a plurality of display sheets 31 provided corresponding to each of the plurality of indicator lights 30 and displaying the district name, and a plurality of covers 32 attached to the housing 2 by overlapping each of the plurality of display sheets 31. Each of the plurality of covers 32 comprises a base material 320 made of a light-transmitting material, a first region 321 provided on a part of one surface of the base material 320 and having light opacity, and a second region 322 provided on a part of the other surface of the base material 320 and having light opacity, and having an appearance different from the first region 321.

[0025] The user of the fire alarm receiver 1 attaches the cover 32 to the display window 20 of the housing 2 so that either the first area 321 or the second area 322 faces forward, according to the type of circuit associated with each area display unit 3. In this way, the user can easily identify the type of circuit associated with the area display unit 3 by the difference in appearance between the first area 321 and the second area 322 of the cover 32. In addition, the characters written on the display sheet 31 can be seen by the user through the base material 320 made of a transparent material, and the characters on the display sheet 31 can be easily changed by reprinting or rewriting them.

[0026] The shape and area of ​​the first region 321 and the second region 322 are not limited to the configurations shown in Figures 3 and 4. Furthermore, the area display unit 3 described in the embodiment can also be applied to a display unit that displays the signal-activated sensor circuit. [Explanation of Symbols]
