Tips for using Solo Aerosols to Test Smoke Detectors

Posted in: Testing Product Support Training

1. Dispenser Use Only

Avoid manually applying smoke from the canister.

The instructions on the side of Solo A5, A10, and A10s clearly state that it should be used within the Solo dispenser only and not by hand. Only use SmokeSabre by hand as this has been specifically designed for hand use.

Why?

Using an aerosol canister designed for dispenser use ensures a controlled release if used correctly. Over-application when used by hand can lead to fewer tests per canister. Additionally, overuse may increase nuisance re-alarms, wasting both time and smoke.

Worst of all, it could shorten the detector’s serviceable life. The competence of a fire engineer should be question if they do not use products has instructed.

2. Be Patient

When using a Solo canister, apply short bursts of smoke—approximately 1 second—and then wait. Instructions say repeat every 10 seconds up to maximum of 5 applications.

Why?

Excessive smoke can trigger unnecessary alarms. A brief burst is sufficient for testing most detectors. Also be aware of detector integrating times, detectors like Multi-sensors can have very long times to alarm if tested with smoke alone.

Patience is required as 40 seconds and long are not that uncommon with some multi-sensors when each channel is tested separately.

3. Consider Temperature

Ambient temperature will cause lingering smoke after a test due to slow evaporation and this leads to nuisance re-alarms and more time per detector.

Whereas a canister stored in a cold car/van overnight will have poor performance due to reduction in internal pressure and change in dispersion rate.

The Solution

Warm the canister gently in your pocket or under warm water, if it’s too cold try not to over apply too much smoke.
