Product Overview

W-SD355 and W-SD355T addressable, wireless photoelectric detectors use a state of the art photoelectric sensing chamber to provide open area protection. The W-SD355T adds thermal sensors that will alarm at a fixed temperature of 135°F (57°C). They are intended for use with the MS-9200UDLS and MS-9600(UD)LS Addressable Fire Alarm Control Panels. The W-SD355 and W-SD355T communicate with the fire alarm control panels through a wireless mesh network to the W-GATE wireless gateway.
