Abstract

To acquires test information including plural types of pieces of information shown by lighting of an indication light from a sensor and determine whether the sensor is normal.SOLUTION: A light reception unit 23 receives light of an indication light 13 from a sensor 1, generates a signal according to a lighting pattern of the received light, and supplies the signal to a processor 21. The signal is a line-encoded signal and is supplied as a serial signal for example. An acquisition unit 211 acquires test information as information regarding a test of the sensor 1 by decoding the serial signal supplied by the light reception unit 23. A determination unit 212 determines whether the sensor 1 is working normally on the basis of the test information acquired by the acquisition unit 211.SELECTED DRAWING: Figure 10

Claims

1. A detector equipped with an indicator light that illuminates when it detects a fire and triggers a fire alarm, wherein the detector illuminates the indicator light to indicate that the object has been detected when the sensor detects an object, and transmits test information, which includes identification information of the device, by encoding the flashing pattern of the indicator light in the transmission path, and a light receiving unit that receives the light from the detector. An acquisition unit that acquires the test information based on the flashing pattern of the light received by the light receiving unit, A determination unit determines whether the sensor is functioning normally based on the test information acquired by the acquisition unit, A housing that covers the sensor and isolates the space around the sensor, A configuration to prompt the aforementioned detector to switch from monitoring mode, which is a fire monitoring state, to test mode, which is a mode in which a test is performed on the device itself, It has, The above configuration includes at least one of the following: a transmitting unit that transmits a start signal to the detector indicating that a test should be started, or a sensing unit that is sensed by a proximity sensor provided in the detector. The test apparatus is provided with a window in the housing section, positioned behind the light receiving section, for visually confirming the light emitted from the indicator light.

2. The aforementioned test information includes sensitivity information indicating the sensitivity of the sensor, The determination unit determines that the sensor is functioning normally if the sensitivity indicated by the sensitivity information is within a predetermined range. The testing apparatus according to claim 1.

3. It has a supply unit that supplies smoke components toward the aforementioned sensor, The determination unit determines that the detector is functioning correctly when the light receiving unit receives light from the indicator light when the supply unit supplies smoke components. The testing apparatus according to claim 1.
