Next, the operation of the device constructed as described above will be described.
5, a description will be given based on the flowchart shown in FIG.
When one of the fire detectors 3, 4, 5 ‥‥ detects the occurrence of a fire, the fire phenomenon detected by the fire detector, for example, fluctuation of light is converted into an electric signal, which is converted into a detection signal by the cable 7 as a detection signal. Is transmitted to The central device 1 determines whether or not a fire has occurred based on the level and duration of the detection signal (step b), and when it is determined that a fire has occurred, activates the alarm 26 (step b). In this case, since the transmitter 29 is not attached (Step C), if the result of the investigation indicates that the report is erroneous, the alarm is stopped by operating the notification release switch 27 (Step E) (Step C). ).

On the other hand, when inspecting the fire detector, a transmitter 29 is attached to the connector 28 of the central unit 1. As a result, the transmitter mounting detector 31 operates and the control device 30
The signal is input to.

In this state, the telescopic tube 11 of the inspection device 8 is
Pull out the tip until it reaches the fire alarm 3 and apply the cover 12 so as to cover the fire detector 3. When the number assigned to the fire detector 3, for example, “3” is input from the keyboard 14 (step), and then the inspection start command switch 15 is turned on (step), the control device 40 turns on the infrared lamp 13. When activated, the fire alarm 3 is irradiated with infrared rays, and at the same time, a timekeeping operation is started (step nu).

When the fire detector 3 is operating normally
Is the time determined by the performance of the fire detector 3 and the performance of the transmission line
After a lapse of (1-2 seconds), the central device 1 will be described later.
The detection signal is received as
The transmitter 29 receives the input of this signal,
The number of fire alarm 3, in this case "3"
We send as number.

The receiver 41 of the inspection device 8 converts this radio signal
Then, it is output to the control device 40 (step). input
Number "3" is the number entered from the keyboard 14 "
3 ", the control device 40 executes the normal notification run.
Turn on the clock 17 and stop the timing operation.
The external line lamp 13 is turned off (step w).

When the normal notification lamp 17 is turned on, the number "
It turns out that the fire detector 3 of 3 "is normal. Further , the response speed can be known from the time data displayed on the display 19, and can be used as a guide for maintenance or the like.

On the other hand, if the inspection start command switch 15 is turned on (step) and the signal from the central unit 1 is not sent within a certain period of time, for example, 3 seconds after the occurrence of the simulated fire, (Step e), the abnormality notification lamp 18 is turned on, the timing operation is stopped, and the infrared lamp 13 is turned off (step f).

On the other hand, as described above, the central device 1 receives the detection signal from the fire detector 3 (step
B) It is determined that a fire has occurred, and the alarm 26 is activated (step b). At this time, since the transmitter 29 is mounted (step c), a detection signal "3" is output from the transmitter 29 (step d). ) After a predetermined time, for example, 2 seconds, elapse (step f), the operation of the alarm device is stopped to prevent noise (step t).

By pressing the inspection end command switch 16 when the inspection for one fire detector is completed,
The inspection device is reset to prepare for the next inspection.
