In FIG. 1, reference numeral 1 is a fire receiver, to which a plurality of monitoring lines L are derived, and a detector S is connected. Also, a district bell line L'is derived corresponding to the monitoring line L, and a district sound B is connected. The fire receiver 1 is provided with a district light 1a and a fire light 1b,
In addition to the test switch 2, a test operation circuit 10 is provided.

According to such a fire receiver, the test switch 2 is operated to switch to the operation test mode, and when the inspector carries out the fog test one by one at the installation location of the sensor S, the sensor S becomes normal. In this case, the fire receiver 1 operates by receiving the alarm signal, and sounds the corresponding district sound B. In the present invention, the ringing pattern of the district sound B is set to a different pattern for each monitoring line L in advance, so that the operation of the sensor S can be confirmed by distinguishing the ringing pattern.

FIG. 2 is a diagram showing an example of a ringing pattern of the district sound B. For example, when the sensor S connected to the third monitoring line L is operated, the bell is intermittently interrupted three times during a short rest period. Sound. Although the ringing pattern determines that the line is the third monitoring line, the ringing pattern is not limited to such an example.

FIG. 3 and FIG. 4 show an example of the fire receiver of the present invention as set forth in claim 1.

In the example of FIG. 3, the operation test circuit 10 provided in the fire receiver 1 causes the main sound 3 of the fire receiver 1 to ring when the sensor S that has issued the test is operating normally. For this reason, one transceiver T is placed near the main sound 3 of the fire receiver 1 for inspection, and the operator carries the other transceiver T and distinguishes the ringing sound of the main sound 2 through the transceivers T, T. It is designed to check the operation.

FIG. 4 shows an example of the ringing pattern of the main sound. The main sound is made to ring twice intermittently, and after a short rest period, the same pattern is repeated.
It is identified as the second monitoring line.

FIGS. 5 and 6 show an example of the fire receiver of the present invention as defined in claim 2.

In the example of FIG. 5, the fire alarm receiver 1 is provided with a notification output terminal 4, and a notification device 5 such as a buzzer, a lamp or a radio device is connected to the notification output terminal 4 for use.
When the inspection and the operator apply the sensor S to issue an alarm, the test operation circuit 10 of the fire receiver 1 receives the alarm signal, and the alarm output terminal 4 connects the issued sensor S. A transfer signal having a pattern corresponding to the monitoring line L is output.

FIG. 6 shows an example of the transfer signal in this case, and a 24V-0V pulse signal is output from the transfer output terminal. The number of pulse signals is different depending on the monitoring line L.

When a notification signal is received from the notification device externally connected to the notification output terminal 4, it outputs light or operation sound according to the pattern.

According to a third aspect of the present invention, the informing device is configured to output an operation confirmation sound having a different pattern for each monitoring line for which a test is issued, or blink a lamp. Externally connect the wireless device (transmitter), install another wireless device (receiver) at the test point,
The transfer output signal can be confirmed at the test site.

It goes without saying that the fire receiver of the present invention should not be limited to the above-mentioned modes, but can be implemented in various modified modes.

According to the fire receiver of the present invention (Claim 1), the operation is discriminated by the ringing pattern of the main sound or the district sound output from the receiver while one operator is wiping the detector. Can be done easily.

According to the fire receivers proposed in claims 2, 3 and 4, a notification device such as a lamp or a wireless device is externally connected to the transfer output terminal to detect it by one worker. If the test is issued while the device is burning, the sensor that issued the test can be easily identified by determining the output.
