Positioning and interconnectedness of smoke alarms is crucial to ensuring how effective a smoke alarm is in alerting people to the presence of a fire.

New laws have come into effect from January 01 2017 applying to new domestic dwellings, rental properties, and properties that are undergoing substantial renovations.

These laws aim to ensure people are more rapidly alerted to the presence of a fire in the home. Zehn Electrical are across legislative change and safety requirements. Safety is one of the core principles of our work.


Safety switches monitor the flow of electricity through a circuit to prevent injury or even death. They automatically shut off your electricity supply when current leak is detected from faulty switches, wiring or electrical appliances in your home. This stops the chance of electrocution or electric burns caused by current flowing to the earth.

Safety switches need to be tested regularly to ensure the mechanism continues to work freely and is not clogged with dirt or other foreign matter. Zehn Electrical are qualified in safety switch testing and upgrades and undertake this important process with precision.
