No Code requirements/guidelines. Follow the specific manufacturer's recommended test methods, which are typically a built-in test mechanism or aerosol test apparatus.

http://www.scorpion-tester.com/ has an innovative solution. Only listed for Europe right now. One of those things you think of and then find it available already.

I've also seen an interconnection to the BAS system such that the keyswitch was replaced with an BAS relay on their controller. The system was programmed to automatically run the test activating each detector for the night in sequence, recording all the damper state changes, then resetting the intelligent panel through a relay. This allowed all the quarterly testing to be done with a very small crew and minimal disruption. This was AHJ approved and then mixed with a periodic smoke entry test using aerosol.

When using aerosol, you may want to confirm the aerosol was UL tested with the type of detectors being used, many hospitals have required this for JCAHO compliance.
