Fire Alarm System Images Free !NEW! Download
Yves Pottenburgh
I noticed my old topic has a 56k warning on it, so i decided to make a new topic. I have alot of FA pics, and my main goal is to make my own fire alarm website, add all the FA pictures I ever took on it, so it will be easier for anyone to look at them. But for now, I will try to reduce the number of photos I post, and maybe make them a smaller size.
-From the cafeteria in my school, there is another picture of an Edwards Adaptabel and an Edwards 270-SPO under each other, a more common sight in the original part of the building. The other alarm pictured is the other bell in the cafeteria, which is a Newer Edwards Adaptabel.
-This is the library of my school, and in here there is one Edwards 270-SPO, A newer Edwards adaptabel, and one of the older ones as well. Here is a video of one of the fire drills we had, where I was in the library at the time it happened. Also there is an Edwards smoke pictured.
-From a hotel in Toronto I stayed at, a voice evacuation fire alarm system. This consists of System Sensor speakers and Simplex lifealarm speakers, Simplex T-Bars, Simplex smokes, and I would say a big FA panel.
-Lastly, this is the FA system at my work! The alarms are a variety of bells, The main lobby has an Edwards 10" adaptabel, one side of the restaurant has an Edwards 6" adaptabel, The other side has 2 6" Mircom bells, as well as the staff room has a Mircom 6" Bell. The pulls also vary. There is 2 Notifier pulls, one in the kitchen and one in the dining room, 2 Mirtone 73303 pulls, one in the staff room and one in the lobby, and an Edwards 270-SPO. The main panel is a Mircom FA-1025T. The system does code 3, which does sound a little fast. I have gotten to silence and reset the system, after we had a kid accidently pull the alarm in the lobby.
Latly, my fire alarm collection so far. There is only a few stuff not pictured, which I had gotten after I took this pick. Those are 2 EST Genesis horn/strobes (red with FIRE on them), a red Edwards Adaptahorn, and a Simplex heat detector.
I wanted to take a moment and discuss something related to the hobbies of several fire alarm enthusiasts, and that is taking pictures of fire alarm devices in public. I had something happen to me today that I feel warrants a discussion.
I am always cautious when in public property, and I rarely take pictures. If I do get pictures, I try to get permission first, and I try to get policy information. The problem is, though, that it is weird when a 14 year old fire alarm collector walks up to an adult and asks the photography policies.
As families and friends get together to celebrate the holiday season, it is important that Delawareans consider fire safety as they decorate their homes and entertain guests. During the holidays, residential fires generally increase. Following a few simple tips will help ensure your family has a happy, fire-safe holiday season.
This alarm was in the student lounge in the Student Union; note the pre-ADA Faraday strobe replacing the old light, and the Faraday 6120 horn behind the grille. This was replaced with a U-HN-MCS in summer 2007. The cafeteria also had a Simplex 2903+2901-9833 horn/light installed in the 1980s, which is still there today.

There were a few replacement Faraday pulls in the Science building as well. Unlike the Student Center, pretty much nothing from the old systems are intact now:
The three buildings now have addressable Notifier systems rebranded by Johnson Controls (Business has an NFS-320, Science and Technology share an NFS2-640!) All the alarms are now Space Age VA4 horn/strobes (on Code-3), and the pulls are NBG-12LXs on ADA-extension adapters. The old heat sensors were replaced with Notifier 2151 detectors as well.
There were also three old wiffle-ball detectors. This one was photoelectric, but the other two were ionization detectors. They were all replaced with i3s last summer when the fire suppression system was redone.
Provides guidance to Authorities Having Jurisdiction (AHJ) for establishing programs to ensure highly reliable fire detection and alarm systems in his or her community. This document (formerly NEMA SB 1-2014) contains a recommended model ordinance to assist AHJ through improving the reliability of existing systems, including dealing with false, or nuisance, alarms.
Fire detection point data describe the center latitude/longitude coordinates of the corresponding satellite pixel in which a potential fire event was detected. The exact location of a fire may differ depending on the spatial resolution of the data set from which the fire detection pixel originates, with spatial offsets typically ranging from 10s-100s m (e.g., VIIRS data) up to +1 km (e.g., GOES data). Fire pixels detected over mountain ranges and/or steep terrain can also show larger locational errors that can be introduced by terrain correction procedures normally applied to satellite geolocation data.
HMS fire and smoke data products are marked with the time stamp representing the corresponding satellite image acquisition (observation) time in Universal Time Coordinated (UTC), and date using the Julian day calendar () (0-365 day of year for regular years, 0-366 for leap years). In order to obtain U.S. Eastern, Central, Mountain and Pacific times, users must subtract 5, 6, 7, 8 hours from UTC time, respectively (4, 5, 6, 7 hours respectively, when daylight saving time is in effect).
Fire pixels do not translate into absolute fire area and their use should serve as a coarse indicator only. Due to the same reasoning described in FAQ-2 above, a fire detection can be produced for fires occupying small fractional areas of the pixel. In fact, only in relatively rare occasions will a fire occupy the entire footprint of a pixel (those cases are typically reserved to large wildfires). As a result, use of the pixel area to estimate fire size could produce gross overestimation of the actual perimeter.
Commission errors may be observed in the satellite fire products due to ambiguity between actively burning fires and other image features predominantly found during the sunlit part of the day. Those occurrences are typically associated with fresh burn scars and sandy soils that can cause an elevated signal in the mid-wave infrared (MIR) channel data. Other false alarm instances may be associated with Sun glint occurrence over optically bright and/or specular surfaces (e.g., large solar panel clusters or metallic rooftops, clouds, and water bodies). Users must also note that thermal anomalies linked to industrial activities (e.g., steel mills, gas flaring) and structural fires in urban environment may be present in these data. Such occurrences are normally removed from the quality-controlled Hazard Mapping System product.
HMS image analysts will try and identify these cases and take the appropriate action to correct the output fire data. Users working independently with VIIRS fire detection product are encouraged to look for alternative observations from previous/next satellite overpasses acquired closer to nadir whenever confronted with suspicious fire pixels matching the description above.
Satellite fire detection products are defined as Level 2 data, therefore relying on the upstream Level 1 radiance files for processing. Level 1 data latency varies greatly between geostationary and polar orbiting system. GOES full disk Level 1 data become available within 20-30 min from the actual observation, whereas the smaller imaging sector covering the Conterminous United States (CONUS) is usually available within 10-15 min from observation. GOES fire data processing adds another 5-15 min to the processing time. Comparatively, polar orbiting (MODIS, VIIRS) Level 1 data become available within 1:30-2:30 h from the time of observation with fire data processing adding another 5-10min. In the case of the HMS outputs, latency can further increase by another 1-3 h on average as image analysts perform detailed data quality assessment analysis.
It really depends on the type of analysis involved in the study. HMS is a forward processing near real-time fire and smoke monitoring system using the best available satellite data at any given time. As a result, any data gap due to planned or unplanned system downtimes or other data flow interruptions will not be back-filled. Moreover, the addition and removal or satellite data sets over time can introduce large variation in system performance. For example, the implementation of S-NPP & NOAA-20 VIIRS 375 m and GOES/ABI 2 km resulted in a significant spike in the number of daily fire pixels output by the system. Similarly, smoke mapping can be greatly affected by the observation conditions (most often as a result of cloud interference) which can lead to incomplete representation of smoke coverage.
The fire sizes depicted in the product are primarily determined by the field of view of the satellite instrument, or the resolution of the analysis tool. They should not be used to estimate specific fire perimeters.
Satellite fire detection data are displayed using a color scheme based on the pixel's fire radiative power (FRP), given in MegaWatts [MW]). Higher FRP values may describe the most active portion of a fire pixel cluster at the moment of observation, whereas absolute values can be greatly influenced by imaging conditions. A fill value of -999 is used when no FRP retrieval is available.
GOES-East Geostationary Lightning Mapping (GLM) sensor data observed over the Conterminous United States in the last 6h. Data points consist of longer duration flashes (> 2s) that have greater potential to start a fire. A small circle will display over the Gulf of Mexico when no such flashes are detected.

Current Red Flag Warning areas flagged by the National Weather Service (NWS) in the United States. These describe areas where wildfire-conducive weather conditions are expected, often including a combination of high winds, low relatively humidity, and warm temperatures. A small triangle will display over the Gulf of Mexico when no such warnings are in effect. For more information please visit:
