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). The W-SD355 and W-SD355T communicate with the fire alarm control panel (FACP) through a wireless mesh network to the W-GATE wireless gateway. Note: Must be used with an ES-200X, ES-50X, MS-9600(UD)LS or MS-9200UDLS FACP.Main FeaturesUnique 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).General InformationName: Fire-Lite W-SD355 Smoke Detector, Honeywell International, Inc, Fire-LiteCategory: Fire-lite Alarms By Honeywell, Fire, Fire Detection Devices, Addressable & Wireless Smoke DetectorsUPC Code: 783863045653Country of origin: Mexico.
