Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall-mounted disaster amplifier alert the unison, or the required location relative to the fire, the buildings.
[0002]
[Prior art]
Conventionally, buildings of a certain size or larger have been obliged to install emergency broadcast equipment under the Fire Service Law. Emergency broadcasting equipment includes a rack-type disaster prevention amplifier with various units such as an operation unit, control unit, power supply unit, etc. installed in a vertically long rack, and a relatively small wall-hanging unit that is directly attached to the building wall. There is a type disaster prevention amplifier.
[0003]
The wall-mounted disaster prevention amplifier has a structure in which the main body is fixed to the wall of the building, and an opening / closing door is rotatably attached to the front surface of the main body. The open / close door is provided with emergency operation members such as a microphone, an emergency start switch, and a broadcast floor selection switch.
[0004]
[Problems to be solved by the invention]
Incidentally, the wall-mounted disaster prevention amplifier includes an operation member whose handling is regulated by the Fire Service Act. Since these operation members are related to the basic operation of the wall-mounted disaster prevention amplifier, it is obliged to arrange them in the housing so that a person other than an operator who is familiar with the apparatus cannot operate.
[0005]
Conventionally, it has been considered that these operation members are arranged in the casing if they are shielded by a lid attached to the front surface of the casing. However, if these operating members are placed inside a lid that can be easily opened and closed by outsiders, it is impossible to prevent unintentional outsiders from operating them. The policy of regulation has been changed to the idea that the part that can only be opened is inside the housing.
[0006]
For this reason, an operation member that has been regulated by law in the past and an operation member that is not regulated by law but that is not frequently touched by a person other than the operator and that has a relatively high operation frequency are the same with simple opening and closing operations. Although it could be placed in the lid, after the change it has become necessary to place it in a separate lid.
[0007]
In other words, operating members that are regulated by law are placed in a lid that cannot be opened unless an instrument is used, and those that are not regulated by law but should be shielded by the lid are relatively frequently operated members. It is necessary to arrange it in the lid that can be manually opened and closed directly without using. For this reason, it is necessary to install two types of lids on the housing, and there has been a disadvantage that the installation space, the number of parts, the number of assembly steps, and the like increase.
[0008]
The present invention has been made to solve such a conventional problem, and a lid for shielding an operation member whose handling is restricted by law, and a lid for shielding an operation member whose handling is not regulated by law. An object of the present invention is to provide a wall-mounted disaster prevention amplifier that can install a body with a small installation space, the number of parts, and assembly man-hours.
[0009]
[Means for Solving the Problems]
Wall-hanging type disaster amplifier according to the invention comprises a shielding lid in front of the broadcast facility is equipped housing, shielding蔽用lid common pivot fulcrum to open and close rotatably to the relative housing is composed of a pair of split lid attached to the housing front, one of the lid of the divided lid one pair has a locking means for holding the closed state with respect to the casing, while The lid has a fixing means for fixing the closed state with respect to the casing, and the other divided lid is configured to be opened by releasing the fixing state of the fixing means with respect to the casing using an instrument. Have.
[0010]
According to the present invention, the lid that shields the operation member whose handling is restricted by law and the lid that shields the operation member whose handling is not regulated by law are reduced in installation space, the number of parts, and the assembly man-hours. A wall-mounted disaster prevention amplifier that can be installed is obtained.
[0011]
