“An ounce of prevention is worth a pound of cure.” Benjamin Franklin Benjamin Franklin’s timeless wisdom applies perfectly to the challenges of maintaining dry fire sprinkler systems through the harsh winter months. Every year, building owners and facility managers face frozen drains, damaged piping, system downtime, and costly repairs, all of which are preventable with the ...
The inspector’s test valve is a vital component of any wet fire sprinkler system. At the heart of this connection is the test orifice. A small but critical feature that certifies the system’s waterflow alarm functions correctly. Both NFPA 13 (Installation of Sprinkler Systems) and NFPA 25 (Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems) provide ...
Proper air venting is essential when designing and installing a wet pipe fire sprinkler system to reduce corrosion risks and ensure system performance. While NFPA 13 allows for different methods of venting air from a sprinkler system, including a manual valve, an automatic air vent, or a remote inspector’s test valve, it is crucial to understand why a remote inspector’s test valve is ...
Irrigation is a cornerstone of agricultural productivity, landscaping, and sustainable water management. Among the various water sources, lakes offer a dependable and eco-friendly solution, especially in regions facing groundwater depletion and irregular rainfall. Harnessing lake water effectively requires specialized equipment and the correct pump, such as an irrigation pump for lake systems ...
Corrosion prevention is crucial for protecting lives and property. Corrosion poses a significant threat in fire sprinkler systems, often remaining undetected until it’s too late, leading to property damage or even loss of life during a fire event. Traditional Inspection, Testing, and Maintenance (ITM) protocols are essential but can inadvertently accelerate corrosion rates by introducing ...
Choosing and placing valves carefully is important for fire sprinkler systems to meet code requirements. The Inspector’s Test Valves and Test and Drain Valves are frequently confused. This is because they perform similar functions but have distinct characteristics and applications. Understanding the differences between these valves is crucial to ensure their proper ...
Make sure to connect the controller to a GFCI-protected circuit for added safety. Step 4: Connecting the Sprinkler Zones Next, connect the sprinkler zones to the controller. Each zone should have its own wire that runs from the controller to the corresponding sprinkler head or valve. ...
A proactive approach to extend the life of your systems. Among the requirements needed to keep commercial fire sprinklers working and code compliant are the routine inspections, which can seem complex. Most of the Inspection, Testing and Maintenance (ITM) of sprinkler systems require a qualified life safety professional, but some of the work can be done by in-house facility personnel. NFPA 25, ...
It is incumbent on hospitals and other medical facilities to maintain sterility wherever needed to keep patients and staff safe. This goes for operating and exam rooms. Healthcare institutions must also safely store surgical scrubs, head covers, sterile surgical implants, equipment, and medication. The goal is to protect these items from contaminants like dust, viruses, and bacteria so they ...
A second task in converting from managing sprinkler systems to SDI systems is to shift paradigms. The irrigator no longer can rely on the performance of the sprinkler, such as visually obvious defects of the system. ...

The requirement Our brief was to produce a thermally buoyant smoke layer in order to test the efficiency of the high level smoke extraction system, activating the VESDA smoke detection system, but without activation of the sprinkler system: We supplied smoke generating equipment, an operator and technical guidance as to how this could be achieved. ...
The distance between the space heater and the deflector plate was set to give a reference air temperature at this thermocouple of 35 - 40ºC (from a deflector plate temperature of approx 190 – 200ºC), sufficient to give thermal buoyancy to the smoke effect without damaging the lighting fittings or operating the sprinkler heads. The Deflector Plate ...
Inspect your irrigation system for leaks and improperly set timers, as well as broken or misdirected sprinkler heads. 6.) Install rain/freeze sensors on your irrigation system and inspect weekly. 7.) ...
Drivable Grass® has originally been designed with the intention to have commonly used spray irrigation systems installed underneath the product, including fitting sprinkler heads through cut voids of the mat or spraying from outside the installation. ...
General housekeeping tips for all workplaces: Don’t block sprinkler heads, fire extinguishers and other emergency equipment. Keep material and equipment at least 18 inches (46 centimetres) away from sprinkler heads. ...
Installing flow meters can help you save thousands of gallons of water each year. Set your sprinklers to water just before dawn is ideal because it reduces losses to wind or evaporation. Adjust sprinklers to avoid waste and ensure uniform distribution. Test the spray patterns of sprinkler systems; check for clogs and a mixed nozzle sizes of ...
Only trained personnel are approved to use portable fire extinguishers. Sprinkler systems are functioning properly and tested annually. Fire alarms are functioning properly and tested annually. ...
To measure and control water pumped into the sprinkler system, a Greyline TTFM 1.0 Transit Time Flowmeter with clamp-on ultrasonic sensors was installed on the outside of the main 6" steel pipe from their pump station. A Rain Bird® control system then manages water distribution to each sprinkler head. Daily flow reports must be provided to ...
With the help of the Acclima systems they were able to pinpoint water distribution weaknesses in the sprinkler heads and replace those spnnkler heads with heads that gave a more even distribution of water over the property, further enhancing the savings. ...
