  • a determination at 51 is made as to whether messages to be output are fire data such as data for actions to be taken when a fire occurs, etc. If the answer is "yes,” the fire action operation is conducted, and if the answer is "no,” the program is branched to a further determination.
  • a determination is made as to whether the messages to be output are messages for instruction manual and/or messages for operation training. If the answer is "yes,” an operation (as shown at 54) for explaining instruction manual for the fire alarm system and the related facilities (in case such facilities are not connected, explanation for them is not necessary as will be described in detail later) and an operation at the time of training are carried out. If the answer is "no,” the program is branched to a further determination.
  • the determination 51 as to a fire data is made with priority, so that, when a fire signal is received during the processing of other messages such as messages for instruction manual etc., the fire action operation 52 is carried out through the determination at 51.

When the operator has put a spot confirming switch of the operating means 14 provided at the signal station to an "on" position, the predetermined flag has been in "1" position. If the answer is "no,” a spot confirming instruction 65 is carried out in a similar manner. This instruction may, for example, be a message "Dial no...., or rush to the spot for making confirmation. When confirmed, depress a confirmation switch.”
  • a further determination as to whether an action after spot confirmation has already been taken is made at 66. This determination is made by checking the position of a corresponding flag of the flag setting means which is in "1" position by an operation confirming signal from the operating means 14 indicating that the sound stopping switch is in the predetermined position. If the answer is "no,” an action instruction 67 after the spot confirmation is carried out in the same manner as described above. This instruction may, for example, be a message "If actual fire, contact the fire station and guide people to a safe place. If not, reset by operating the resetting switch and return the sound stopping switch to the predetermined position.”
  • the fire action operation as described above is carried out in a manner such that whether the operator has carried out required operations or taken required action is determined by the processing means 11 and necessary message or messages selected from the messages concerning measures to be taken when a fire starts are output, in the form of voice, according to the result of the determination.
  • the operator can conduct necessary operation and take the necessary action.
  • it is possible to employ a system in which the determination is not carried out and all the messages are repeated sequantially. In this case, it suffices to apply only a start address of the messages to be output to the voice synthesizing means 20, so that the program of the processing means 11 can be simplified and the load thereof can be reduced.
  • the operation 54 for instruction manual is for explaining a method for handling the fire alarm system and the related equipments and facilities.

This explanation is output by an instruction manual output requesting signal from the manual input means 15.
  • An operation 55 for training is carried out following the operation for instruction manual in the embodiment as illustrated, but it may be carried out independently.
  • a determination isfirst made at 80 as to whether the training starting message is over. If the answer is "no," a message 81 for starting training such as "Now, operation training starts. A fire alarm is given, so please conduct operations according to the instructions" is uttered. Then, a fire alarm 82 is given.
  • the determination at 80 is "yes” the program is branched, passing the aforesaid operation. Then, the routine of the fire action operation 52 is called allowing the messages for the measures to be taken at the time of fire to be uttered. Thereafter, a determination as to whether the fire action has been taken is made at 83. If the answer is "yes,” such a message as "Now, training is over.” is uttered to end the operation (as shown at 84).
