How an FST-951 Notifier operatesMayara
Commercial buildings have to abide by a flurry of government guidelines on a daily basis. Like with many aspects of life, there is a certain standard that must always be met. For instance, commercial buildings require a working fire prevention system to keep the building and its occupants safe and secure. There’s an eclectic variety of fire alarm systems on the market, and it’s important to be selective when finding the right one for you. To help narrow down your search, we’ll break down how an FST-951 Notifier operates. This piece of fire prevention equipment may only be one part of the whole system, but it’s certainly an important one.
What is it an FST-951 Notifier?
Notifier’s FST-951 is a type of fire alarm device that uses thermal detection to monitor the building. This detection system uses a device known as a thermistor to detect dangerous levels of heat in the surrounding area.
FST-951 Notifier Thermistor
The thermistor is a very common type of heat detector, or “resistor”, that is triggered by an increase in temperature interacting with the thermistor’s level of resistance. This may sound odd but it’s actually quite straight forward: when the temperature increases, it causes the thermistor’s resistance to decrease.
On the other hand, when the temperature begins decreasing, it causes the thermistor’s resistance to increase. In the event of a thermistor’s resistance decreasing enough, it will trigger the system’s alarm. FST-951 units have state-of-the-art thermistor devices that will quickly respond to emergencies and notify building occupants with maximum efficiency.
FST-951’s heat detection system comes with two different detection options. These options will both trigger the alarm in the case of an emergency, but they detect heat in very different ways.
The first option is the most common form of heat detection you’ll find in most commercial businesses and households: fixed-temperature. Fixed-temperature detectors will trigger the system’s alarm if intense heat enters the device and melts a substance that sits inside: eutectic alloys. Using fixed temperature is the best option if you’re placing a unit in any kitchens your building has.
The second heat detection option is rate-of-rise. A rate-of-rise detector ditches the alloys in favor of electronic sensors. These systems operate by detecting sharp spikes in temperature in the designated area, which is why they’re not exactly the best option for kitchens where you’ll be doing frequent cooking. The rate-of-rise detection unit will trigger the alarm once it senses a temperature spike of around 12 or 15 degrees Fahrenheit.
Whether you choose the rate-of detection or fixed-temperature detection, your system will be vigilant in detecting excessive heat. At the end of the day, when choosing the detection method, you should consider what makes the most sense for the surrounding environment the unit will be sitting in and monitoring at all times.
FST-951s also features a set of LED lights on the exterior to alert nearby building occupants. If an emergency erupts, your fire alarm system’s control panel will notify the FST-951 unit, causing its LED lights to begin emitting. You can turn the LED light off, or you can change it to emit either a static light or a blinking light during emergencies. You can change the color of the light as well: green, red, and amber options are available.
Rotary Decimals Switches
FST-951 detection units contain rotary decimal switches for use with addressable fire alarm systems. An addressable fire alarm system is a collection of heat and smoke detection units that all link back to one fire alarm control unit. Each device receives a specific location, or “address,” that the control panel will recognize.
This means that if a fire occurs and one detection unit goes off, the fire alarm control unit will be able to recognize which unit it is and where it can be found. The rotary switch that comes with the FST-951 is what allows you to set the address for any given unit.
Summary for the FST-951 Notifier
As you can see, this is a lot of information to take in. Before buying the right units for your building, you need to truly know the ins and outs of each device. However, without holding the device in front of you, some of these components can seem a bit confusing. So, we’ll break them down once more, so you can understand all the most important aspects of the FST-951.
Firstly, FST-951 are thermal detection units that use a thermistor to detect excessive heat and trigger the system’s alarm. The method of detection is programmable and can be set to two options: fixed-temperature detection or rate-of-rise detection.
Additionally, FST-951 units connect to your alarm system’s control unit with the help of rotary decimal switches. Once you give the units a designated address, they will send notifications to your control panel if an emergency occurs. If an alarm does begin to sound, the unique address of each alarm will allow the control panel to show exactly where the device is.
FST-951 also carries two LED lights on the exterior. When the fire alarm control unit receives a notification signaling that an emergency is occurring, it will then trigger the LED lights to begin emitting. Your FST-951 unit can be set to either emit a blinking light or a static light to alert building occupants of alarm activation, or you can turn the LED off entirely.
Now that you know how an FST-951 notifier operates, you can decide whether it’s or not the right fit for your building. All commercial buildings require a fire prevention system, so don’t conduct your search without knowing anything about the devices you’re buying. By learning and understanding the ins and outs of an effective fire alarm system, you can keep you, your building, and its occupants safe and secure on a daily basis.
