To functionally test your Siemens AD2-XHR Air Duct Monitoring Housing, follow these steps for reliable operation and alarm verification: First, you can use the TG-11 smoke test canister, using the AD-TGN testing nozzle (sold separately). Insert the nozzle into the red plug's hole on the unit cover. Press the canister for about half a second to release the test gas, avoiding excessive spraying to prevent contamination. Second, after gas release, wait 15 to 20 seconds. The detector should activate, lighting the and triggering the duct unit functions. Alarm relays will change state, and any connected accessories will also activate. If a test gas isn't available, try an alternative method. Remove the cover, press the cover removal switch, and blow smoke from a smoldering cotton wick or punk directly at the detector head, which should trigger the alarm within one minute. For detailed testing instructions specific to your detector model (PE-11, FP-11, HFP-11, HFPO-11), consult the Installation Instructions in the manual (see Table A on page 12). Remember to conduct these tests regularly, as recommended in the manual, to ensure the AD2-XHR is functioning correctly and ready to alert you.
