The Notifier FST-951R-IV is an intelligent addressable rate-of-rise thermal detector in ivory. It works with both FlashScan and CLIP systems and comes from the FST-951 Series, the direct replacement for the FST-851 Series. It protects property in areas where a heat detector is the right choice and reports its own address to the panel over the SLC.
Key Features
- Rate-of-rise detection at 15°F (8.3°C) per minute
- Works with FlashScan and CLIP protocols ("-IV" suffix)
- Rotary decimal switches set the point ID address for exact detector location
- Two LEDs visible through 360° blink red when polled and turn steady red in alarm
- Built-in functional test switch activated by an external magnet; remote test from the panel
- Built-in tamper-resistant feature and sleek low-profile design

FAQ
What replaces the FST-951R-IV?
The replacement is the FST-951R. Note that Notifier lists the white FST-951R as FlashScan only, while the FST-951R-IV supports FlashScan and CLIP, so check the panel protocol before swapping.
How does it detect heat?
It is a rate-of-rise thermal sensor that responds to a rise of 15°F (8.3°C) per minute.
What voltage does it need?
15 to 32 VDC peak, with 200 µA maximum average standby current and 4.5 mA maximum when the LED is on.
Which bases does it use?
Notifier intelligent bases such as the B300-6-IV 6 in. flanged base or the B501-IV 4 in. base, plus relay, isolator and sounder bases.
