photoelectricaddressablewireless

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 135⁰F (57⁰C). 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. Unique single-source, dual-chamber design to respond quickly and dependably to a broad range of fires. Removable cover and insect-resistant screen for simple field cleaning. Withstands air velocities up to 4,000 feet-per-minute (20 m/sec.) without triggering a false alarm. Factory preset at 1.5% nominal sensitivity for panel alarm threshold level. Cascading Mesh Wireless Technology (902-928 MHz frequency). Any wireless device can be added to act as a repeater. Requires (4) CR-123A batteries (included).
