The sensor function switching control unit 3 is configured to select at least one of the heat detection unit 11 and the smoke detection unit 12 based on a sensor function selection table 31 assigned in advance according to the installation location selected by the installation location setting switch 2. Is automatically set as an effective fire detection unit 1 to function.
[0021]
That is, if the display unit 21 of the installation location setting switch 2 is set in accordance with the location where the residential fire alarm A is installed, the heat sensing unit 11 or the smoke sensing unit 12 is determined by the sensor function selection table 31. When any one of the fire detectors 1 is automatically selected and set, for example, when the heat detector 11 is selected as an effective fire detector 1, it operates as a constant temperature heat sensor or a differential heat sensor.
[0022]
However, the fire detecting section 1 can also use the heat detecting section 11 and the smoke detecting section 12 in combination, and depending on the installation location, a constant temperature type, a differential type heat detector, a smoke detector, or these. Can also function as a combined heat and smoke detector.
[0023]
In addition, the sensor function switching control unit 3 has a sensor sensitivity control in which the thermal sensitivity of the heat sensing unit 11 and the smoke sensitivity of the smoke sensing unit 12 are preset to, for example, either “normal” or “sensitive”. Means 32 may be provided. If such a sensor sensitivity control means 32 is provided, the detection sensitivity of the fire detection unit 1 automatically set according to the setting location of the installation location setting switch 2 is adjusted to a predetermined optimum value. Detection sensitivity can be set in advance.
[0024]
Also, the sensor function switching control unit 3 includes a sensor alarm sound control unit 33 in which the volume of the alarm sound emitted from the alarm sound output unit 4 is set to, for example, “normal” or “loud” in advance. If such a sensor alarm sound control means 33 is provided, the optimum alarm sound volume according to the installation location is automatically set only by setting the installation location setting switch 2. it can.
[0025]
Further, the sensor function switching control unit 3 stores the sensor accumulation time, which is set in advance to either “short” or “long”, from when a fire is detected to when the alarm sound is emitted. A control means 34 may be further provided. If such a sensor accumulation time control means 34 is provided, only by setting the installation location setting switch 2, the optimal accumulation time according to the installation location is automatically set. Can be set.
[0026]
The sensor sensitivity control means 32, the sensor alarm sound control means 33, and the sensor accumulation time control means 34 are preset in accordance with various conditions. Smoke sensitivity “sensitive”, heat sensitivity “sensitive”, accumulation time “short”, (2) In places where people usually work, smoke sensitivity “normal”, heat sensitivity “normal”, accumulation time “long”, (3) In places where heat and smoke are likely to occur, the accumulation time is "long", in places where people leave during cooking, in places where there are many people who are hard to hear, in places where there are usually no people and it is difficult to hear alarm sounds, etc. It is desirable to set in advance so that the alarm volume is “loud”.
[0027]
Therefore, as shown in FIG. 3, for example, when the installation location is a corridor or stairs, the location is a place where there is little movement of people, and usually corresponds to a place where there are no people and it is difficult to hear the alarm sound. In the sensor function selection table 31, the smoke sensitivity is “sensitive”, the heat sensitivity is “sensitive”, the storage time is “short”, and the storage volume is “loud”.
[0028]
Such a fire alarm A for houses operates as follows.
[0029]
First, the residential fire alarm A is installed at a desired location, and the installation location setting switch 2 is set in accordance with the installation location.
[0030]
At the same time as this setting is made, the contents of the sensor function selection table 31 are automatically specified to the contents most suitable for the installation location.
[0031]
For example, if the installation location setting switch 2 is set to "corridor / stairs", this fire alarm A for a house will have a smoke sensitivity "sensitive", a heat sensitivity "sensitive", as shown in FIG. The function is automatically set as having a function of “accumulation time“ short ”/ accumulation volume“ loud ”. When a fire is detected, an alarm is sounded based on these functions.
