Description

  The present invention relates to a sensitivity tester for testing the sensitivity of a fire sensor.

  Fire detectors, for example smoke detectors, are required to have a sensitivity test at regular intervals in addition to the activation test by smoke. The sensitivity test is a test that applies a voltage to a fire sensor and checks the voltage when a fire is notified. At the time of the sensitivity test, the worker removes the fire sensor installed in the caution area from the base of the ceiling and attaches it to the measurement base of the sensitivity tester, and performs the test by supplying the test voltage to the fire sensor.

  The sensitivity tester contacts the terminal to the fire detector, and the voltage level of the test voltage is set in a fixed range preset to the fire detection output voltage (noise output voltage) input to the fire judgment circuit of the fire detector. (Test voltage sweep range, for example, 0.2 V to 0.6 V) is swept and superimposed. The fire judgment circuit (not shown) of the fire sensor outputs a fire alarm signal (substantially short circuit current) when the inputted superimposed voltage (noise output voltage + test voltage) becomes higher than the reference level. The sensitivity tester detects a fire notification signal (substantially short circuit current) output from the fire determination circuit (not shown) of the fire detector by the fire detection circuit (not shown), and the fire detector fires Detect a notification. And let the test voltage at the time of fire alert be the sensitivity voltage. If this sensitivity voltage is within a predetermined voltage range (the acceptance reference range, for example, the initial sensitivity voltage plus or minus 10% range) with respect to the initial sensitivity voltage, it is determined that the fire sensor is normal and the sensitivity voltage is If out of the acceptance criteria range, it is judged that the fire detector is abnormal. Since the initial sensitivity voltage and the like of the fire sensor are described on the nameplate affixed to the back of the fire sensor, the operator inputs it into the sensitivity tester before conducting the test. The first voltage value of the test voltage sweep range can be changed by the initial sensitivity voltage (see Patent Document 1).

The blade bracket 4 engages with a blade fitting (not shown) provided on the back surface, which is the mounting surface of the fire detector 2, to hold the fire detector 2. The blade bracket 4 supplies power to the fire detector 2 via a blade fitting (not shown), and receives a fire alarm signal (substantially short circuit current) from the fire detector 2. The terminals 51, 52 of the sensitivity tester 1 send the test voltage to the fire sensor 2. In the sensitivity tester 1 of the first embodiment, two sets of terminals 51 and 52 are provided so that tests of two types of fire sensors 2 with different contact positions can be performed. Further, the confirmation window 6 is a through hole penetrating from the front side to the back side of the sensitivity tester 1 and provided at a position where the fire sensor information display such as the test voltage is opposed when the fire sensor 2 is attached. There is. Then, the fire sensor information can be visually recognized and confirmed from the outside of the sensitivity tester through the confirmation window 6.

The cross key 9 is an input unit, and the input digit is moved by the left and right arrow keys, and the numerical value is increased or decreased by the up and down arrow keys.

Next, how to conduct the sensitivity test will be described.
First, the operator holds the power / decision button 8 long to turn on the sensitivity tester 1. Next, the fire sensor 2 removed from the base of the ceiling is attached to the measurement base 3 of the sensitivity tester 1 shown in FIGS. 1 (a) and 1 (b) to obtain the state shown in FIG. . At this time, at the same time a blade fitting (not shown) provided on the back of the fire detector 2 is fitted into the blade bracket 4 of the sensitivity tester 1, a contact (not shown) on the back of the fire detector 2 is Either terminal 51 or terminal 52 contacts.

  In this state, if looking through the confirmation window 6 from the back of the sensitivity tester 1, as shown in FIG. 2 (c), the fire sensor information display such as the initial sensitivity voltage described on the nameplate on the back of the fire sensor 2 is visible. , Worker reads fire detector information. Since the confirmation window 6 is a through hole, the worker attaches the fire detector 2 to the sensitivity tester 1 and fire detector information described on the name plate of the fire detector 2 through the confirmation window 6 The display is directly viewable and viewable. Then, the operator inputs the initial sensitivity voltage using the cross key 9, and presses the power / decision button 8 for a short time to decide the input value. Then, the sensitivity test starts with the set initial sensitivity voltage as test setting information.

The sensitivity tester 1 supplies the gradually changing test voltage to the fire sensor 2 via the terminal 51 or the terminal 52 to cause the fire sensor 2 to fire.
That is, as described in the background art section, the fire judgment circuit (not shown) of the fire sensor 2 sets the pair of blade fittings (see FIG. 6) when the input superimposed voltage (noise output voltage + test voltage) becomes equal to or higher than the reference level. A fire alarm signal (generally short circuit current) is output between (not shown). In the sensitivity tester 1, a fire detection circuit (not shown) is connected between a pair of blade brackets 4, and the fire detection circuit (not shown) is a fire judgment circuit (not shown) of the fire detector. The fire alarm signal (substantially short circuit current) output from the above is detected to detect that the fire sensor 2 has issued a fire alarm.
Then, the sensitivity tester 1 obtains a sensitivity voltage which is a test voltage value when a fire is notified. It is determined that the sensitivity voltage is normal if it is within the acceptance reference range which is the plus or minus range of the initial sensitivity voltage, and is determined to be abnormal if it is outside the acceptance reference range.

  As shown in the confirmation window 6 of FIG. 2 (c), if the fire sensor information display for the test described on the nameplate is the initial sensitivity voltage of 0.48 V, the operator should The input digit is moved with the left and right arrow keys using the key 9, and the numerical value is increased or decreased with the up and down arrow keys to adjust the display of the display unit 7 to 0.48. Then, the power / decision button 8 is briefly pressed.

  Then, the test voltage is supplied from the sensitivity tester 1 to the fire sensor 2 while sweeping from a preset voltage range, for example, 0.2 V to 0.6 V. Then, the fire detector 2 fires a fire, and the fire voltage value at that time is obtained. The sensitivity tester 1 determines that the alarm voltage value is normal if it is within the acceptance reference range of 0.48 V, which is the initial sensitivity voltage, for example, plus or minus 10%, and is within the plus or minus 10% of 0.48 V If it is out of range, it is judged as abnormal.

  When the sensitivity test is completed, the test result is displayed on the display unit 7 of the sensitivity tester 1 and a sound is also notified. If the test result is normal, "Sensitivity test result: Normal" is displayed and a short beep sounds, but if it is abnormal, "Sensitivity test result: Necessary exchange" is displayed and "Peepy" Sounds long and long.

In the first embodiment, although the initial sensitivity voltage is input using the cross key 9, the cross key 9 can also be used to input the type of the fire sensor 2 (an example of fire sensor information). In this case, fire sensor information such as the acceptance reference range (plus or minus range of the initial sensitivity voltage) of the sensitivity voltage corresponding to each model is stored in the sensitivity tester, and the sensitivity is determined according to the input model. Acceptable reference range of voltage can be set. For example, when the acceptance reference range of the sensitivity voltage differs depending on the model, it is useful to input the model.
Therefore, the nameplate on the back of the fire sensor 2 may be a device where the model name of the fire sensor 2 or the like is described as fire sensor information in addition to the initial sensitivity voltage.
