Description

The present invention relates to an alarm device for detecting and alarming an abnormality (abnormality) such as a fire or a gas leak.

  Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in homes have become popular. Of these, residential fire alarms are referred to as residential alarms.

  In such a house alarm, a sensor unit and an alarm unit are integrated in the house alarm, and when a fire is detected by the sensor unit, a fire alarm is output from the alarm unit by voice message, etc. Because it is possible to perform fire monitoring and alarm with a single residence guard without requiring any receiving equipment, it is easy to install and inexpensive, and it is widely used with the mandatory installation in ordinary houses.

  Moreover, in recent years, a wireless home alarm for a linked alarm system has been put into practical use, in which a plurality of home alarms can communicate with each other and abnormality information of one home alarm can be alarmed by other alarm devices. ing.

  In a linked alarm system that performs wireless communication, if a fire is detected by a certain home alarm, the home alarm that detected the fire is, for example, “Woo Woo Fire Alarm has been activated. Please send a voice message saying "Please," while the linked house alarm outputs a voice message saying "Check if a fire alarm for each Woo has been activated". In addition, the indicator light of the interlocking home alarm device is turned on, and the indicator light of the interlocking destination home alarm device is blinking so that the interlock source or the interlocking destination can be distinguished from the display of the indicator light.

  In such a linked alarm system, when installing a plurality of purchased mortgages, registration work is first performed to form a linked group. The registration work arranges a plurality of home alarms on a table etc. and arranges them relatively close to each other, and if you operate the registration button provided on the back of the alarm device according to a predetermined registration procedure, mutual communication between home alarms Thus, for example, a registration process for forming a linked group is automatically executed.

  However, in the home alarm used for such a conventional interlocking alarm system, a plurality of home alarms for which the above registration work has been completed will be carried to their respective installation locations. When the number increases, the house alarm is bulky and the built-in battery is heavy, so there is a problem that it is difficult to carry a plurality of house alarms at the same time without dropping them.

  For this reason, for example, a small number of one or two units are transported to the installation location, but this takes time.

  Therefore, if the house guards unpacked for registration work are returned to the original storage box, they can be carried together by stacking the storage boxes. However, this is also cumbersome and not practical. In addition, it is only necessary to be able to prepare boxes and containers that collectively store a plurality of registered home alarms, but the maximum number of home alarms that can be used in the interlocking alarm system is, for example, 12, and that number is stored. It is expected that a suitable box or container cannot be prepared immediately.

  In order to solve such problems, it is an object of the present invention to provide a residential alarm having a structure that allows simple and easy simultaneous transportation of a plurality of unpacked residential alarms. .

  In addition, although the above-mentioned group registration work can be performed for a plurality of home guards located at a distance from each other as long as the radio signal can reach, here, for example, registration is performed assuming a normal work procedure and environment. A case where a plurality of target home guards 10 are arranged and operated on the same table is described as an example.

That is, the present invention is not limited to transportation after registration work, and provides the convenience of easily transporting a plurality of home alarm devices simultaneously for any purpose.

  The present invention provides an alarm device provided with an alarm device main body and an attachment plate detachably attached to the alarm device main body, wherein a connection structure for detachably connecting another alarm device main body is provided on the attachment plate. Features.

  FIG. 1 is a front view of a wireless interlocking house alarm as an embodiment of an alarm device according to the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a rear view thereof.

  In FIG. 1 to FIG. 3, the housing of the house alarm device 10 of the present embodiment includes a cover 12 and a main body 14. A mounting plate 24 is detachably provided on the back surface of the main body 14. The mounting plate 24 is detached from the housing of the home alarm device 10 and previously attached to the ceiling surface, and then the housing of the home security device 10 is rotationally fitted to the mounting plate 24 so that the main body of the home security device 10 is mounted. Is a so-called ceiling-mounted mounting adapter, and is provided separately from a wall-mounted mounting hook 15 described later.

  A projecting portion 16 having a substantially circular shape when viewed from the front is projected from the center of the cover 12 in the front view, and a plurality of smoke inlets 16a are opened at predetermined intervals in the circumferential direction of the cover 12, and further smoke detection is provided inside thereof. For example, when the smoke from the fire reaches a predetermined concentration, the fire is detected.

  An acoustic hole 18 made up of a plurality of slits is provided on the lower left side of the cover 12 when viewed from the front, and a buzzer and a speaker are built in behind this so that various information can be notified by outputting an alarm sound or a voice message. An alarm stop switch 20 is provided on the lower side of the cover 12 when viewed from the front.

  The alarm stop switch 20 includes a switch cover formed of a translucent member and a tact switch (not shown) arranged inside the switch cover. In the vicinity of the tact switch inside the switch cover, an LED 22 for displaying an alarm is arranged as indicated by a dotted line. When the LED 22 is lit, flashing, or blinking, the operating light is transmitted through the switch cover and visually recognized from the outside. I can do it.

  The alarm stop switch 20 functions as an alarm stop switch or an inspection switch according to the operation state of the home alarm device 10 during operation. For example, when the alarm stop switch 20 is operated at the time of a fire alarm of the residential alarm 10, it functions as an alarm stop switch that stops the alarm. Further, when the alarm stop switch 20 is operated in the normal monitoring state of the home alarm device 10, it functions as an inspection switch for executing a predetermined inspection operation and notifying an inspection result by a voice message.

  A mounting hook 15 for wall surface installation having an insertion hole in the substantially central portion is provided at the upper part on the back side of the main body 14. Screws or the like are screwed into the wall surface of the room to be installed, and the insertion hole of the mounting hook 15 By hooking it through a screw, the residential alarm 10 can be fixedly installed on a wall surface or the like in a so-called wall-hanging manner.

  The home alarm device 10 has a function of transmitting and receiving event signals (interlocking signals) to each other wirelessly, and can perform fire monitoring of the entire house in cooperation with a plurality of units. Assuming that a fire has occurred in a house in which such a plurality of home alarm devices 10 are installed, the home alarm device at the fire occurrence site detects the fire and starts alarming by alarm sound output and alarm display output. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  The alerting home alarm device functions as a link source, and wirelessly transmits an event signal indicating the occurrence of a fire to the other lock alarm device as the link destination. On the other hand, when the other resident alarm device receives an event signal indicating the occurrence of a fire from the linking alarm device, the alarm operation as the interlock destination is performed by the alarm sound output and the alarm display output. .

  As the alarm sound of the home alarm that became the linkage source, for example, “Please confirm that the Woo-Woo Fire Alarm has been activated” is output by voice message. On the other hand, the linked home alarm outputs a voice message such as “Please check if another fire alarm is activated” as an alarm sound.

  Moreover, as a display (alarm display) output associated with the alarm of the home alarm device serving as the interlock source, for example, the LED 22 is turned on. On the other hand, the LED 22 is blinked in the interlocking house police. Thereby, the user can distinguish the alarm display output by the LED 22 in the interlock source alarm and the interlock destination alarm.

  It should be noted that the interlocking source LED 22 may be blinking and the interlocking destination LED 22 may be lit, or the same LED 22 may be blinking or blinking or lit for both the interlocking source alarm and the interlocking destination alarm. Further, for example, a red LED and a yellow LED may be provided, and the two-color display may be performed such that the interlocking source drives the red LED and the interlocking destination drives the yellow LED. Of course, a two-color LED capable of emitting both red and yellow by combining two LEDs can be adopted.

  When the alarm stop switch 20 is operated in a state in which the home alarm is outputting an alarm sound (or during a period when a fire is detected), the alarm sound and alarm display stop processing is performed. At this time, for example, when an alarm stop operation is performed at the interlocking source residence alarm, the alarms of all the residence policers are stopped and the alarm stop operation is performed at one of the interlocking destination residence alarms. In such a case, the alarm of the interlocking source resident alarm is not stopped, and the alarm is interlocked so that the alarm of the interlocking destination resident alarm is stopped.

  In addition, in the residential alarm 10 of FIG. 1, the smoke detector 16 is provided, and the residential alarm which detects smoke due to fire by observing the smoke concentration is taken as an example. In addition to fire alarms, constant temperature or differential type alarms with temperature detection elements such as thermistors that detect heat from fire, and other alarms that detect other physical phenomena associated with fire Alarm devices that detect gas leaks, various alarm devices that detect intruders, earthquakes, and other abnormalities (abnormalities), and alarm devices that combine these alarm devices are also included in the scope of the present invention.

  FIG. 4 shows a mounting plate 24 removed from the main body of the home guard 10, a side view of the home guard 10 with the mounting plate 24 removed, and a rear view of the main body of the home guard 10 in this state. As shown in FIG. 4 (A), when the mounting plate 24 is rotated clockwise, for example, with respect to the main body 14 of the home guard 10, the fitting piece 26 comes out of the fitting hole 30 on the back of the main body shown in FIG. 4 (B).
