The SD/355 and SD/355T addressable, low-profile plugin photoelectric detectors use a state-of-the-ar t photoelectric sensing chamber with communications to provide open area protection and are used exclusively with Fire•Lite’s Addressable Fire Alarm Control Panels (FACPs). The SD / 355T adds thermal sensors that will alarm at a fixed temperature of 135°F (57°C). Since these detectors are addressable, they will help emergency personnel quickly locate a fire during its early stages, potentially saving precious rescue time while also reducing property damage. Two LEDs on each sensor light to provide a local, visible sensor indication. Remote LED annunciator capability is available as an optional accessory (P/N RA100Z(A)). The SD/355R is a remote test capable detector for use with D355PL or DNR(W) duct smoke detector housings.

SLC loop: • Tw o-wire loop connection. • Unit uses base for wiring. Addressing: • Add ressable by device. •Direct Decade entry of address: 01 – 99 with MS-9200 series, and 01 – 159 with MS-9600 series Architecture: • Unique single-source, dual-chamber design to respond quickly and dependably to a broad range of fires. • Sleek, low-profile design. • Integral communications and built-in type identification. • Built-in tamper-resistant feature. • Removable cover and insect-resistant screen for simple field cleaning Operation: • With stands 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. • Visible LED “blinks” when the unit is addressed (communicating with the fire panel) and latches on in alarm. Mechanicals: • Sealed against back pressure. • Direct surface mounting or electrical box mounting. • Mounts to: 3.5"" (8.89 cm) octagonal box, or 4.0"" square electrical box (using 3.0"" mud ring). Other system features: • Fully coated circuit boards and superior RF/transient protection. • 94 - V0 plastic flammability rating. • Low standby current. Options: • Remote LED output conn ection (P/N RA100Z).
