Safety Alert – Passive Infrared (PIR) Sensors

Safety alert PIR sensors
Approvals

The electrical safety regulator in Victoria has recently released a safety alert concerning the installation of Passive Infrared (PIR) sensors.

This is in response to an electrician receiving an electric shock, whilst installing a PIR sensor in September 2017.

You can read the full safety alert on the Energy Safe Victoria website by clicking HERE.

When selecting an PIR sensor you should select one that has Australian electrical safety approvals, unless the device is powered from a DC source.

ADM is Australia’s authorised distributor of Hytronik PIR and microwave sensors.

All PIR sensors offered by ADM carry Australian electrical safety approvals.

Hytronik is a manufacturer of quality products and have included a number of safety features into their products such as:

  • Protective shrouds around the AC power terminals
  • Options to adjust settings either with a Handheld Remote Control

or

  • By removing a cover that only exposes the sensor and the setting controls, but NOT the mains terminals

In the below diagram for the HMW21motion sensor item 3 is the safety cover for the AC terminals. To make adjustments the user only needs to remove the lens (item 2), which just exposes the sensor and the rotary switch.

ADM stocks a wide range of Hytronik sensors, which offers you a wide range of different control solutions.

Within the Hytronik range you have the following options:

  • On / Off Control
  • 1-10V Dimming
  • DALI Dimming
  • Push Dimming
  • Daylight Harvesting
  • Daylight Sensing

There is also a wide range of different mounting options. Sensors can be flush mounted, or surface mounted. Sensors are available that can be hidden in a false ceiling and others can be installed inside light fittings. There are also sensors specifically designed for mounting on high bay lights.

For example, if you wanted a stand-alone flush mount microwave sensor with 1-10V dimming you may wish to use the Hytronik HMW21.

However, if you needed a flush mount daylight harvesting sensor, then you could use the Hytronik HIR24. This particular model has DALI dimming, but is also available with 1-10V dimming under part number HIR22.
