General The NOTIFIER® FSP-951 Series intelligent plug-in smoke detectors are designed for both performance and aesthetics, and are direct replacements for the FSP-851 Series. A new modern, sleek, contemporary design and enhanced optical sensing chamber is engineered to sense smoke produced by a wide range of combustion sources in accordance with more stringent code standards. The FSP-951 Series detector sensitivity can be programmed in the control panel software. Sensitivity is continuously monitored and reported to the panel. Point ID capability allows each detector’s address to be set with rotary, decimal address switches, providing exact detector location for selective maintenance when chamber contamination reaches an unacceptable level. Dual electronic thermistors add 135°F (57°C) fixed temperature thermal sensing on the FSP-951T. The FSP-951R is a remote test capable detector for use with DNR Series duct detector housings. FSP-951 series detectors are available for both FlashScan® and CLIP applications as designated. Features SLC LOOP: • Two-wire SLC loop connection • Unit uses base for wiring • Compatible with FlashScan® and CLIP protocol systems • Stable communication technique with noise immunity ADDRESSING: • Addressable by device • Rotary, decimal addressing (Refer to the NOTIFIER panel manuals for device capacity.) ARCHITECTURE: • Sleek, low-profile, stylish design • Unique single-source design to respond quickly and dependably to a broad range of fires • Integral communications and built-in device-type identification • Built-in tamper resistant feature • Remote test feature from the panel • Walk test with address display (an address on 121 will blink the detector LED: 12-[pause]-1(FlashScan systems only) • Built-in functional test switch activated by external magnet • Removable cover and insect-resistant screen for simple field cleaning • Expanded color options OPERATION: • Designed to meet UL 268 7th Edition • Factory preset at 1.5% nominal sensitivity for panel alarm threshold level • LED “blinks” when the unit is polled (communicating with the fire panel) and latches in alarm. • Low standby current MECHANICALS: • Sealed against back pressure • SEMS screws for wiring of the separate base • Designed for direct-surface or electrical-box mounting • Plugs into separate base for ease of installation and maintenance • Separate base allows interchange of photoelectric, ionization and thermal sensors OPTIONS: • Optional relay, isolator, and sounder bases
