Abstract

A fire receiver including: an operation selection switch for selecting a desired operation from a plurality of operations that can be executed; an address selection switch for selecting a desired address from different addresses respectively given to a plurality of fire detectors and lines; an address changing device for continuously changing the address to be selected in accordance with the operation of the address selection switch; an address display device for displaying the address to be instructed which has been changed by the address changing device; and a command device for commanding a fire detector or a line corresponding to the address displayed by the address display device to perform the operation selected by the operation selection switch.

Claims

1. A fire receiver comprising:

operation selection switch means for selecting a desired operation from a plurality of operations that can be executed;

address selection switch means for selecting a desired address from different addresses respectively given to a plurality of fire detectors and lines;

address changing means for continuously changing the address to be selected in accordance with the operation of said address selection switch means;

address display means for displaying the address to be instructed which has been changed by said address changing means; and

command means for commanding a fire detector or a line corresponding to the address displayed by said address display means to perform the operation selected by said operation selection switch means.

7. A fire receiver according to claim 1 wherein said address display means includes a CRT.

2. A fire receiver according to claim 1wherein said address changing means stops the continuous change of the address for a first predetermined time regardless of the operation of said address selection switch means if a predetermined address has been displayed by said address display means.

3. A fire receiver according to claim 2 wherein said address changing means stops the continuous change of the address for a second predetermined time regardless of the operation of said address selection switch means if said address changing means starts performing an address changing operation, the second predetermined time being shorter than the first predetermined time.

4. A fire receiver according to claim 1wherein said address display means also displays a term for specifying a fire detector or a line corresponding to the address to be displayed.

5. A fire receiver according to claim 1wherein said address selection switch means comprises an upward scroll key and a downward scroll key.

6. A fire receiver according to claim 1wherein said address display means includes a liquid crystal panel.

8. A fire receiver connected to devices in a fire alarm system, said fire receiver comprising:

a CPU;

operation switch means connected to said CPU;

a transmitting/receiving circuit connected to said CPU and arranged to transmit/receive signals to and from said devices in said fire alarm system; and

display means connected to said CPU,

said display means including;

an operation display portion for displaying the state of the operation performed by said fire alarm system;

a menu display portion for displaying a plurality of menus of the contents of operations; and

an operation description display portion for displaying the description of a switch operation about the contents of the operation of a menu of said plurality of said menus of the contents of the operations displayed in said menu display portion that has been selected by said operation switch means.

9. A fire receiver according to claim 8 wherein said operation description display portion displays information denoting a subject device, at least one operation of which is set from among stop of local alarm, interlock stopping, retransmission stopping, start of fire-block and smoke exhausting and restoration of fire-block and smoke exhausting.

10. A fire receiver according to claim 9 wherein said operation description display portion displays information denoting the devices disposed in front and in the rear of said displayed subject device, said information being displayed on the two sides of the information of said displayed subject device.

11. A fire receiver according to claim 9 wherein said operation description display portion displays said subject device by means of terms.

12. A fire receiver according to claim 8 wherein said display means includes a liquid crystal panel.

13. A fire receiver according to claim 8 wherein said display means includes a CRT.

14. A fire receiver according to claim 8 wherein said CPU causes said display means to display a predetermined content at a low brightness if said fire alarm system is supervising a fire and causes said display means to display a predetermined content at a high brightness if fire information has been supplied from said devices in said fire alarm system through said transmitting/receiving circuit.

15. A fire receiver according to claim 14 wherein said display means includes a liquid crystal panel.

16. A fire receiver according to claim 15 wherein said display means includes a backlight for irradiating said liquid crystal panel.

17. A fire receiver according to claim 16 wherein said CPU lowers the brightness of display performed by said liquid crystal panel by lighting off said backlight and raises the brightness of display performed by said liquid crystal panel by lighting on said backlight.

18. A fire receiver according to claim 17 wherein said CPU flashes on and off said backlight when said CPU has received fire information from said device in said fire alarm system through said transmitting/receiving circuit and continuously lights on said back light when said operation switch means has been operated in a predetermined manner.

19. A fire receiver according to claim 14 wherein said display means includes a CRT.

20. A fire receiver according to claim 19 wherein said CPU continuously raises or lowers the brightness of said CRT when said CPU has received fire information from the device in said fire alarm system through said transmitting/receiving circuit and causes said CRT to perform a display when said operation switch means has been operated in a predetermined manner.
