The Solo A10 and A10S smoke detector tester aerosols contain a non-flammable, non-toxic simulated smoke and are designed for use in the Solo 330 or Solo 332. These dispensers provide a seal around the smoke detector, delivering the test smoke directly to the detector while helping to reduce the amount of A10 or A10S used per test. Supplied in either a 150ml or 250ml aerosol canister, the Solo tester sprays provide a quick alarm response and clearing time and are universally suitable for all types and makes of point smoke detector.
