Applying the latest occupancy sensing technology to a fixture can increase energy savings by up to a whopping 80%. This game changer allows end users to reap the rebates and incentives offered by many utility organizations when using energy efficient luminaires.
Now let’s talk stairwell fixtures. When it’s time to select the ideal fixture for your stairwell, which sensor do you choose? You may have heard of Passive Infrared (PIR), but it’s not the best sensor to use in a stairwell as it requires a straight ‘line of sight’ making the detection of an occupant too late.
The two most common occupancy sensors we recommend from our portfolio of stairwell lighting fixtures are Ultrasonic and Microwave. Whether you are looking for a fixture for a commercial, industrial or vandal prone stairwell environment we make it easier for you to decide.
See the chart below:
|Features & Benefits||Ultrasonic |
|Cost||Premium Technology||Economical Technology|
|No. Sensor is exposed on the exterior of the fixture||Yes. Sensor is mounted within the fixture to protect it from dust, moisture or vandalism|
|Detects Occupant Before Arriving at Landing||Yes||Yes. However, microwaves can pass through walls causing false triggers|
