Abstract
A fire receiver includes a light emitting device; a supervisory control apparatus for performing supervisory control based on information from a plurality of terminal devices such as fire detectors, and for displaying the information by causing the light emitting device to emit light; and a brightness changing device for changing the brightness of the light emitting device in response to the brightness of the surrounding environment.
Claims16
A fire receiver comprising:
- light emitting means;
- supervisory control means for receiving information regarding a plurality of terminal devices including fire detectors, for performing supervisory control based on the information, and for causing said light emitting means to emit light based on the information;
- brightness changing means for changing a brightness of said light emitting means based on a brightness of a surrounding environment;
- detecting means for detecting an abnormality, wherein the abnormality comprises at least one of a fire and a breakdown of one of the terminal devices;
- forcing means for forcibly controlling said brightness changing means such that said light emitting means emits light at a predetermined brightness if said detecting means detects the abnormality, regardless of the brightness of the surrounding environment;
- displaying means;
- and
- a display content table having stored therein, in each of a plurality of languages, terminal information including installation locations and types of the terminal devices, wherein the supervisory control means reads out the terminal information from the display content table and causes said displaying means to display the terminal information.
