Description

The 850P is a state-of-the-art smoke detector using a photoelectric sensor which, in conjunction with the MX fire alarm panel, suits most fire detection applications. The 850P incorporates a unique “mousehole” design optical chamber with superior signal to noise ratio providing high resilience to dust and dirt which means reduced service costs. In addition a unique chamber cover actually draws slow moving smoke into the chamber to provide a more responsive detector. A stainless steel insect screen is used on the 850P to provide a high degree of immunity to small insects.
