Bottom line: This ionisation smoke alarm is excellent at detecting fast (flaming) fires and it comes with a long-life battery. But it’s extremely poor at detecting slow (smouldering) fires. There are more effective smoke alarms than this.

About our test
Our test was conducted in the fire laboratory of the Building Research Association (BRANZ). We purchased 3 examples of each model. Our results are the average of the performances of the 3 examples.
The alarms were fixed to a ceiling panel in a mocked-up hallway adjacent to the door opening of a fireproof room (which was about the size of a single-car garage).
In both tests, the smoke density was measured at the location of the alarms using a laser light-source and detector.

WARNING: Ionisation smoke alarms have been proven by Australian Government (CSIRO) testing to have life-threatening defects.
Take the NZFS's advice and ONLY install photoelectric alarms.
The Australasian Fire & Emergency Service Authorities Council (AFAC) is the peak representative body of all New Zealand and Australian fire brigades.
AFAC's official position of 01 June, 2006 states:
"That all residential accommodation be fitted with photoelectric smoke alarms . . . Ionisation smoke alarms may not operate in time to alert occupants early enough to escape from smouldering fires."
No, this product has too many drawbacks.
