Claims (11)

A fire alarm system comprising: a sensor line to which a plurality of fire detectors are connected; and a fire receiver to which a plurality of the detector lines are connected, wherein the fire receiver receives a fire signal from the fire detector. In
The fire receiver includes a test switch, a control unit that is set to a test mode based on an operation of the test switch, a connection number storage unit that stores a connection number of fire detectors connected to each sensor line, A fire alarm facility, comprising: a notification number storage unit that stores a notification number of a fire detector that has transmitted a fire signal for each detector line in the test mode setting state. The control means compares the number of fire detector connections stored in the connection number storage unit with the number of fire detector reports stored in the notification number storage unit for each sensor line in the test mode setting state. The fire alarm system according to claim 1, wherein, if they match, the district bell corresponding to the matched sensor line is caused to make a predetermined ringing. The control means sets the number of fire detector connections stored in the connection number storage unit and the number of fire detector notifications stored in the notification number storage unit for all sensor lines in the test mode setting state. The fire alarm system according to claim 2, wherein, when they are compared, the predetermined district bell is made to ring different from the predetermined ringing. The fire receiver is a display unit that displays whether or not there is a fire detector that misses the alarm test for each sensor line based on the stored contents of the connection number memory unit and the alarm number memory unit as the alarm test result. The fire alarm system according to claim 1, comprising: 5. The fire alarm system according to claim 4, wherein the display section is a district indicator lamp provided corresponding to each sensor line. The control means compares the number of fire detector connections stored in the connection number storage unit with the number of fire detector notifications stored in the notification number storage unit for each detector line as the alarm test result. 6. The fire alarm system according to claim 5, wherein the display state of the district indicator lamp corresponding to the sensor line is different depending on whether or not they match. The control means blinks the corresponding area indicator lamps in the order of the line numbers of the sensor lines as the alarm test results by the number of connected fire detectors stored in the connection number storage unit and stores the number of alarms to be reported. 6. The fire alarm system according to claim 5, wherein the flash alarm is flashed by the number of fire detectors stored in the unit. The fire receiver includes a test result storage switch and a test result storage unit,
Based on the operation of the test result storage switch, the control means is stored in the connection number and notification number storage unit of the fire detector stored in the connection number storage unit in correspondence with the line number of each sensor line. The fire alarm system according to claim 1, wherein the number of fire alarms to be reported is stored in the test result storage unit. The fire receiver comprises means for sending a test mode start signal to the fire detector based on an operation of the test switch;
When the fire detector receives the test mode start signal, the fire detector is set to a mode under test to control the indicator lamp to a predetermined lighting state, and when a fire is detected in the setting state of the mode under test, the display The fire alarm system according to claim 1, further comprising a control unit that controls a lamp to a display state different from the predetermined lighting state. 10. The fire alarm system according to claim 9 , wherein the control means causes the indicator lamp to function as a fire confirmation lamp in the normal monitoring mode setting state. In a fire alarm facility in which a plurality of fire detectors are connected to a detector line from a fire receiver, the fire receiver performs signal transmission by polling, and receives a fire signal from the fire detector,
The fire receiver includes a test switch for setting a normal monitoring mode or a test mode;
Mode storage means for storing a setting state of the normal monitoring mode or the test mode based on the operation of the test switch;
A notification address storage means for storing an address of a fire detector that has sent a fire signal when the test mode is set;
A means for sending a predetermined light emission control command to each fire detector based on the storage contents of the mode storage means and the notification address storage means,
The fire detector is provided with control means for controlling a display state of an indicator lamp based on the predetermined light emission control command.
