The Problem: Humidity and Smoke Alarms

Smoke alarms located in coastal Queensland and Northern NSW were randomly triggered – mainly early morning.

The Cause: 3am False Alarms 

Commonly occurring between 1-5 am, trapped humid air cools and condenses within the smoke alarm, when temperatures at night reach the dew point.

Solution: An Advanced Detection Sensor

The PSA Lifesaver Advance Sensor.

Another PSA innovation The new Lifesaver 240V model is a completely new design incorporating the Advance Sensor chamber.  The sensor is designed specifically for Australian conditions, enabling the models LIF6800 and LIF6800RL to withstand high temperatures and extreme humidity levels.

Resistance To Moisture Triggers

The Advance Sensor has been specially designed to be resistant to moisture-related triggers that commonly occur during high-humidity events.

Anti Static Chamber

The chamber of the new Advance Sensor is equipped with an anti-static feature, effectively repelling dust, minimising the chance of dust accumulation and false alarms.

Reduced Insect Mesh

The insect mesh of the Advance Sensor has been minimised, to decrease the chance of bugs triggering false alarms, without compromising the detection performance of the alarm.



Faults over 12 months in 40+ sites.


Faults and tech calls.

From October 2022, rigorous testing and trials of the Advance Sensor smoke alarms were conducted across 40 different sites in previously problematic coastal locations throughout Queensland, Northern NSW, and WA. The field trials were a resounding success. 

Tested and approved to Australian Standards the new LIF6800 and LIF6800RL models were launched in September 2023.
