A memory 4 including a RAM for setting a storage and a work area, a memory 5 including a RAM for storing a function selected by the function selection switches SWc and SWd, and a signal between the signal processing unit 2 and the input unit 1 The I / O unit 6 performs input / output. The memories 4 and 5 may be the same memory or independent memories. In addition to the above configuration, a function of controlling the state of each district such as a district window display device and main sound is provided. Further, the I / O unit 6 and the memories 3 to 5 and the signal processing unit 2 are connected by an address bus, a data bus and a control bus.

FIG. 2 shows the regular inspection mode switch SW.
a, an example in which the construction mode switch SWb is arranged in the operation unit C is shown. The function selection switches SWc and SWd are provided in the panel of the fire alarm receiver A, and are composed of, for example, dip switches. Here, as the function at the time of periodic inspection important in the present invention, transfer stop, fire hydrant interlock stop, test recovery state,
There is a state of accumulation release, and the function at the time of construction is, in addition to the transfer stop and fire hydrant interlock stop similar to that at the time of regular inspection, individual disconnection display, main sound 2 times (the number of times may be several times. ,
Also, it may be a time (several seconds) instead of the number of times. Automatic stop after ringing and a fault sound twice (the number of times may be several times,
It may also be time (several seconds) instead of the number of times) such as automatic stop after ringing.

Thus, the function selection switches SWc and SW are previously prepared.
Depending on d, necessary functions to be operated at the time of operating the regular inspection mode switch SWa and the construction mode switch SWb are selected and set. The setting contents are read by the signal processing unit 2 via the I / O unit 6 when the power of the fire alarm receiver A is turned on or periodically after the power is turned on, and the selected contents are written in the memory 5.

When the periodic inspection mode switch SWa is operated at the time of periodic inspection and the construction mode switch SWb is operated at the time of construction, the signal processing section 2 reads the function stored in the memory 5 and the function concerned. Set the operation status of fire receiver A to the operation. Here, the function in the construction mode has the following features.

In other words, when the fire detector S is not completely connected to the detector line L ₁₁ ..., the line is in a broken state, and at that time, the disconnection display is performed by blinking on the district display device. It's hard to see. Therefore, in the construction mode, individual disconnection display stop can be set to stop the blinking display. Therefore, the work of connecting the terminator E at the time of construction can be omitted.

Further, since the sounding of a fault sound due to the disconnection of the fire detector S, the confirmation of the operation of the fire detector and the alarming of the detector due to dust occur in large numbers during the construction, after the main sound and the fault sound are sounded, for example, twice. By operating the automatic stop function, it is not necessary to stop each sound for each ringing, and since it is not a complete stop, it can be confirmed as necessary.

In the above embodiment, the regular inspection mode switch SWa and the construction mode switch SWb are provided side by side, but as long as the receiver has one function,
This corresponds to the embodiment corresponding to the invention described in claim 1 or 4.
