The 885WP-B is a 2 wire fixed temperature Type B heat detector. This detector is designed to provide open area protection in areas subject to moisture. It is sealed against the entry of moisture to a rating of IP67. The LED will latch on when the detector is in alarm. Detectors are used with a mounting base that permits mounting directly on to a 50mm or 60mm junction box. The 885WP-B includes a tamperresistant feature that prevents its removal from the mounting base without the use of a key.
