PCT No. PCT/CH94/00010 Sec. 371 Date Oct. 11, 1994 Sec. 102(e) Date Oct. 11, 1994 PCT Filed Jan. 21, 1994 PCT Pub. No. WO94/18653 PCT Pub. Date Aug. 18, 1994.A device (7) for testing the operation of smoke detectors (3) has a housing (1) which is open at one end and can be placed over the smoke detector (3). A test light source (5) in the housing provides light pulses which radiate into the inside of the smoke detector (3) under test. The test device also has a test light detector (4) that receives light coming from the smoke-indicating light source (15) of the smoke detector (3) and controls the test light source (5) in relation to the received light. The light pulse of the test light source (5) is received by the smoke-indicating light detector (14) of the smoke detector (3). By checking if the smoke detector (3) goes into the alarm state, it can be ascertained whether it is in an operational condition. |
