Tyco 811PH optical smoke + heat detector (516.800.500.Y) is a state-of-the-art detector allowing a full set of detection modes to be implemented in the MX detection panel to suit most smoke and heat detection applications. The 811PH incorporates a unique mousehole design optical chamber with an unrivalled 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. The unique design provides immunity to small insects and thrips without the need for a separate thrip filter. The 811PH provides all the features of MX VIRTUAL detectors including self verification, temperature and smoke level indication and unrivalled service functions.
