Is your Home or business premise Electrically Safe?

A Lonergan and Muhovics electrician can do a full safety audit of your home or business and provide a report with recommendations.

Safety switches are mandatory on all power circuits and recommended on lighting circuits. We can fit these to your main switch board for a lot less than you would think. Safety switches save lives!!

Is your home more than 20 years old? If so there is a good chance that your switch board has ceramic wire type fuses. Whilst it is not a mandatory requirement to upgrade these to switch type circuit breakers, We highly recommends that this upgrade be done to ensure you and your family’s safety. If the incorrect fuse wire is replaced in a ceramic fuse a fire can be started by a failure of the fuse to blow in the event of a faulty appliance.We specialise in lighting retrofit technologies and we use a full-service, turnkey approach to save our clients up to 60% on their facility energy bills. Give us a call today and let us answer your questions about whether a lighting retrofit audit would benefit your facility.

Daylight Harvesting

Daylight harvesting is used in conjunction with light level management and takes advantage of natural sunlight by dimming lighting in areas that are sufficiently lit through windows and skylights. As sunlight decreases light level sensors increase the level of artificial light to compensate. Not only will this save energy but also enhance the comfort of building occupants.

PIR Occupancy Sensors

PIR occupancy sensing is a useful tool for illuminating rooms that are used on an inconsistent basis. Storage areas, meeting rooms and toilet facilities fitted with PIR sensors will activate lighting when someone enters the room. A timer is used to switch lights off when no movement is detected for a period off time. Ultrasonic detectors can also be used in to provide increased sensitivity. Occupancy sensing provides the convenience of automatic switching along with energy savings, as lights are switched off when required.


Schedules are used to switch lights on in time for start-of-business and switch lights off at the end of the day. Different parts of a business day may have different operating hours so separate schedules can be programmed for various locations within a building.


Timers can be used in conjunction with wall switches to enable lights and facilities such as air conditioning to switch off after a predefined period. Timers are commonly used in conjunction with occupancy sensors to ensure lights remain on for a minimum period of time after movement is sensed. This allows for occupied periods where there is no movement, while prolonging the lifetime of lamps by preventing excessive on/off cycling.


Scene settings combine events together to create a particular effect, such as dimming lighting levels. Scenes easily recreate the different lighting the different lighting levels used at various times of the day for applications such as restaurants and hotels. Scenes are also useful in conference rooms and theatres or virtually any application where various actions are performed simultaneously.
