  However, in the conventional configuration, the inspection operation may be continued even when an abnormality occurs in the communication line due to an emergency such as a fire or when a fire signal is input from the fire alarm facility. In this case, for example, even if a fire has occurred, the power supply, which is a commercial power supply, is often not shut off. There is a problem that the lighting time for emergency lighting is shortened after the power is consumed and an abnormality occurs in the power supply.

  In order to solve this, the present applicant has filed in Japanese Patent Application No. 2005-348243 for an emergency lighting device that shifts to the normal mode when there is an abnormality in the communication via the communication line in the inspection mode.

  According to this, when there is an abnormality in communication via the communication line, the battery is charged as long as the power supply is normal, and the lamp is lit for as long as possible in case of an abnormality in the power supply in preparation for the occurrence of an abnormality in the power supply It can be made to.

Operation to 11 is possible.

  The control means 10 continuously monitors the lighting devices 11 connected via the communication means 12, and automatically switches the lighting devices 11 according to a programmed schedule or by manual operation. In addition, weekly inspections and periodic inspections are performed, and history information is recorded. That is, for each lighting device 11, the control means 10 constantly monitors the lamp L life, non-lighting, battery 24 abnormality, lighting circuit abnormality, and communication means abnormality, and an interval of 2 to 6 weeks. A weekly inspection set in step 3 and a regular periodic inspection set at intervals of 3 to 12 months. Lamp L abnormality, lamp L life, battery 24 abnormality, battery 24 life, and other lighting circuits Such as abnormalities of appliances, communication abnormalities, etc. are monitored, and history information is recorded for each lighting device 11.

  Next, the operation of the illumination device 11 will be described.

  Each lighting device 11 enters an interlock mode controlled by the control means 10 when a predetermined signal is input to the communication means connection unit 31 from the communication line constituting the communication means 12 when the power is turned on, and the predetermined signal is input. Otherwise, the normal mode that operates independently is set.

In the interlock mode, the normal mode and the inspection mode are switched in accordance with an instruction from the control means 10. Then, in the normal mode, the power supply A is a normal state, the lighting device 20 charges the battery 24 as well as light the lamp L with the power of the power A. When the power source A becomes abnormal, the lighting device 20 lights the lamp L with the power of the battery 24.

On the other hand, when the inspection start signal transmitted from the control means 10 is received and the inspection mode is shifted to the inspection mode, the lighting device 20 is disconnected from the normal power source A for a specified time, and the lamp L is lit by the power of the battery 24. Then, the life of the battery 24 is determined and the normal operation of the lighting device 20 is confirmed, and the history is recorded in the control means 10. In the weekly inspection, the specified time is a short-time emergency lighting such as one minute, and the lamp L life, non-lighting, battery 24 life, and lighting circuit abnormality are monitored. Also, in regular inspections, emergency lighting is performed for a rated time such as 20 minutes or 60 minutes, and the battery capacity due to the discharge of the battery 24 is confirmed.

  Further, in the inspection mode, even when there is an abnormality in communication via the communication means 12 or when the operation means 29 is operated automatically or manually, as long as the power supply A is normal, the normal mode is entered. The lighting device 20 lights the lamp L with the power of the power source A and charges the battery 24. In other words, if the communication means connection unit 31 cannot receive a signal due to a communication line interruption, a failure of the control means 10 or a power failure, or if the detection circuit 34 detects that the operation means 29 has been operated, Therefore, as long as the power source A is normal, the lighting device 20 turns on the lamp L with the power of the power source A and charges the battery 24.

  Furthermore, when a fire occurrence signal from the fire alarm equipment 43 is input to the contact input terminal block 52, a relay 57 provided between the control device main body 45 and the communication terminal block 51 is interlocked with the signal input. It operates to open a part of the communication line between the control device main body 45 and the communication terminal block 51. Then, since the signal from the control device main body 45 is not input to the communication terminal block 51, the lighting device 11 connected from the communication terminal block 51 via the communication means 12 is determined as a communication abnormality. Therefore, when the lighting device 11 is in the lighting mode and the fire occurrence signal from the fire alarm equipment 43 is input to the control means 10, the lighting device 11 automatically shifts to the normal mode.

According the present embodiment, provided with a relay 57 is forcibly released forced breaking means you connectivity communication with the control means 10 interlocked to a signal of a fire occurrence information and the illumination device 11 from the fire alarm system 43 As a result, the inspection mode of the lighting device 11 can be stopped in conjunction with the fire occurrence signal with certainty, and the transition from the inspection mode to the normal mode can be ensured. Thus, as long as the power source A is normal, the lighting device 20 lights the lamp L with the power of the power source A and charges the battery 24 to prepare for the occurrence of an abnormality in the power source A without consuming the battery 24. The lamp L can be lit for as long as possible in the event of an abnormality.

  In addition, even when it is intended to add a function to shift to the normal mode in conjunction with the fire occurrence signal of the fire alarm equipment 43 to the existing emergency lighting system, the lighting device 11 of the present embodiment is already provided. For existing systems, it is only necessary to add a relay 57 that is linked to the signal input from the fire alarm equipment 43 between the control device main body 45 and the communication terminal block 51.
