Acro Series
WESTIRE ACRO PHOTOCELLS
The alternative Dusk to Dawn photocell solution to cater for your budgetary needs for Cost & Energy Saving
Accuracy
The Acro NEMA Dusk to Dawn photocell utilises a filtered silicon based ambient light sensor and microprocessor control running advanced algorithms that more accurately determine calculated midnight and part night switching.
Longevity
Engineered in the EU with a 15 year design life and manufactured in-house using only high quality name brand components, the AcRo series photocells are renowned in the industry for their unparalleled quality and reliability.
We pay more attention than any other photocell designer to the sky’s blue and red zones to ensure negligible sensitivity to infra-red and ultra-violet radiation.
