JPH0944767A - Compact fire alarm - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a fire alarm compact in size, simple in attachment and capable of being carried if necessary by miniaturizing all of a sensing part, a power supply part, a control part, and an alarm part of the alarm and attaching it to a ceiling or a wall with screws or hanging it on a hook of a wall or the like to complete the attaching construction. SOLUTION: A sensing part 1 is arranged at the front end, and a power supply part 2, a control part 3, and an alarm generation part 4 are built in one plate in the rear, and a cord and a plug 8 for AC power and a battery case 7 for DC power are attached. The sensing part 1 has such structure that either a sensor which senses a fire by smoke or a sensor which senses it by heat can be attached. The power supply part 2 receives an AC current and converts it into a DC, and a backup DC power source for stop of the AC power source or a battery as a power source which is required at the time of carrying the main body can be used. The alarm generation part 4 receives the signal from the control part 3 to generate an alarm.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to each home, travel accommodation,
Alternatively, it can be used as an alarm to notify the occurrence of a fire in a place where there is a risk of fire, such as a temporary work place or a greenhouse.

[0002]

2. Description of the Related Art In conventional fire alarms, a fire detection part, an alarm generation part, and a part for controlling them are made independently, and they are connected by an electric wire, and a control panel is provided in the control part. It is a large system, and installation work must be done by a specialist.

[0003]

As described above, the conventional fire alarm is a systemized device, which is difficult to install in a general household and the installation situation is extremely low. Therefore, it is as compact as the present invention. It is necessary to provide a fire alarm that is easy to install and portable if necessary.

[0004]

According to the present invention, all of the main parts of the alarm device, that is, the sensing part, the power supply part, the control part and the alarm part are made compact and compact, and the installation work is screwed to the ceiling or wall. All you have to do is hook it on a hook such as a wall.
It features a simple structure in which only batteries can be inserted.

[0005]

EXAMPLE An example of the present invention will be described below, but the present invention is not limited to this example.

The sensing section is arranged at the tip, and the power source section, the control section, and the alarm generating section are built in one plate at the rear,
Attach the cord and plug for AC power supply and the battery case for DC power supply.

The sensor part has a structure that can be attached either by smoke or by heat in the event of a fire.

The power supply unit has a structure that receives an alternating current and converts it into a direct current, and can use a direct current power supply for backing up when the alternating current power supply is stopped or a battery as a power supply when carrying the main body.

The control unit receives a signal from the sensor and sends an alarm generation signal to the alarm generation unit, and when the AC power supply is stopped, the entire necessary power supply is promptly supplied to a built-in DC battery. It has a switching mechanism, and the signal sent from the sensor to the alarm generator will continue to be sent until it is artificially reset.

The alarm generation unit is a mechanism for generating an alarm in response to a signal from the control unit, and the alarm sound can generate various alarm sounds such as a bell, a buzzer and an electronic sound individually or by combining them. And

[0011]

As described above in detail, the fire alarm is
By making it compact, the user can insert the power plug into a household outlet, fix the main body to the ceiling or wall with screws, or hook it on a hook so that it can be used for simple construction, travel and exchange. When there is no power supply, it can be used as a portable device with a battery.

Claims (1)

[Claims] 1. In a fire alarm device, the installation work only needs to be fastened to the ceiling or wall of the room with a few screws or hooked on a hook such as a wall. For power supply work, an electrical plug attached to an outlet must be installed. The main components (sensor, power supply, controller, alarm generator) of the main unit can be integrated compactly so that you can simply insert them or replace the batteries, or make them compact enough to be portable even if they are split.
