How many tests will I get from an ES3 cartridge?

ES3 can deliver up to 250 tests per cartridge.

Why am I getting fewer tests than the maximum?

A test cycle is defined as 30 seconds and provides of 15 seconds of smoke output in 3x five second intervals. Testing in excess of thirty seconds will reduce the maximum number of tests from a single cartridge.

What is the shelf life of Solo ES3 cartridges?

The shelf life of ES3 will be affected by the storage conditions it is exposed to and is normally several years greater than the 12 month warranty period. ES3 cartridges should be stored in a cool, dry environment and kept out of direct sunlight.

My Solo 365 isn’t producing smoke, even with a new cartridge. What can I do?

Your Solo 365 may need to run a manual purge cycle. Power on the tester and then press and hold the return button. The status LEDs will begin to flash blue to symbolise a manual purge. Continue to hold the return button for two minutes or until there is smoke dispensing within the test cup.

Is smoke from ES3 cartridges different to Solo aerosols?

Yes. ES3 cartridges use a unique smoke fluid to produce smoke. The smoke generated is more realistic than that of a Solo aerosol and it is compatible with a wider range of detectors
