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
Installation
FSP-951 Series plug-in intelligent smoke detectors use a detach-
able base to simplify installation, service and maintenance. Installa-
tion instructions are shipped with each detector.
Mount detector base (all base types) on an electrical backbox which
is at least 1.5" (3.81 cm) deep. For a chart of compatible junction
boxes, see DN-60054.
NOTE: Because of the inherent supervision provided by the SLC loop,
end-of-line resistors are not required. Wiring “T-taps” or branches are
permitted for Style 4 (Class “B”) wiring only.
When using relay or sounder bases, consult the ISO-X(A) installation
sheet I56-1380 for device limitations between isolator modules and iso-
lator bases.
Construction
These detectors are constructed of fire-resistant plastic. The FSP-
951 Series plug-in intelligent smoke detectors are designed to com-
mercial standards and offer an attractive appearance.
Operation
Each FSP-951 Series detector uses one of the panel’s addresses
(total limit is panel dependent) on the NOTIFIER Signaling Line Circuit (SLC). It responds to regular polls from the control panel and
reports its type and the status. If it receives a test command from the
panel (or a local magnet test), it stimulates its electronics and
reports an alarm. It blinks its LEDs when polled and turns the LEDs
on when commanded by the panel. The FSP-951 Series offers features and performance that represent the latest in smoke detector
technology.
DETECTOR SPACING AND APPLICATIONS
NOTIFIER recommends spacing detectors in compliance with NFPA
72. In low airflow applications with smooth ceiling, space detectors
30 feet (9.1m). For specific information regarding detector spacing,
placement, and special applications refer to NFPA 72. A System
Smoke Detector Application Guide, document A05-1003, is available at www.systemsensor.com.
