Technical Specifications for GA902
Noise Activated Warning Sign
| OPERATION |
| The microphone receives noise and passes it to the built in sound level meter where it is compared to the pre-set trigger level which if exceeded, switches on the twin fluorescent lamps to illuminate the warning sign. Once the noise in the area falls below the threshold for more than a pre-set time the lamps are extinguished. |
| SETTING THE ACTIVATED NOISE LEVEL |
| The unit is factory calibrated to 85dBA and a series of internal switches enables the user to select the desired trigger level in steps of 2.5dB. |
