In-Duct Smoke Detector

The PAD300-DD is an analog addressable photoelectric duct smoke detector (in duct) or mounted in the PAD300-DUCT or PAD300- DUCTR with sampling tubes extending into or traversing a duct. This detector is compatible with any fire alarm control panel that has the Potter Addressable Device (PAD) protocol. The PAD300-DD is listed to comply with the requirements of UL 268 A. The detector and the control panel communicate over a proven and robust digital communication path and the system analyzes the information at the device. The total polling speed is less than five (5) seconds, well under the UL requirements. The detector is compatible with any of the PAD300 series detector bases and simply twists on. The PAD300-DD is addressed using DIP switches in the rear of the detector and can be easily programmed in the field without special tools.
