SENSITIVITY TEST SYSTEM FOR PHOTOELECTRIC SMOKE DETECTOR |
摘要 |
A tester device is disclosed for a photoelectric smoke detector. The tester, when actuated, increases the intensity of light emitted by a light source to simulate in the sample chamber by such light scattering and reflecting off chamber walls, an amount of light which would be scattered by a predetermined concentration of smoke to which a photoelectric sensor is responsive and causes an indication that the detector is functioning as intended. |
