At Net Safety Monitoring we engineer our products with the lowest power consumption and the widest voltage range possible because we
know this allows us to offer two distinct advantages over other products in the market: huge savings for our customers and enhanced system stability.
First let's talk about system stability and performance, our MILLENNIUM II SERIES GAS DETECTORS and
our PHOENIX TRIPLE IR FLAME DETECTOR both have the
widest voltage ranges available in the market, 10 - 32 Vdc on 12 and 24 Vdc systems. So tying our products into any exisiting power
network is never an issue.
More importantly though - in the event of a common voltage drop, not only do our detectors continue functioning
normally but they are not forced into a start-up sequence from the temporary lack of power. For some sensors this can mean up to 15 minutes,
during which no detection is taking place! And in many installations these regular voltage drops will initiate safety system faults which lead to costly plant shutdowns.
With Net Safety products these common issues are virtually eliminated.

Now let's talk about design and installation, whether you're in the design phase of your project or expanding on an existing installation, factoring in the
low power consumption levels with Net Safety flame and gas detection can greatly improve your bottomline and minimize regulatory requirements.

Installation costs are immediately realized through standard lighter gauge cabling. Net Safety instruments require only 18 AWG for both gas and flame installations,
which means lowered material and labour costs. And utilizing a digital signal between transmitters and gas sensors means fast, stable communications and eliminates the need for
signal enhancements over long distances. Some of our competitors require as high as 14 AWG as a minimum gauge, proprietary cabling, and signal boosts every 15 meters!
But this is just the beginning...
UPS systems are required to provide reliable back-up power to process control systems, instrumentation, motor
starting and data processing critical to protecting personnel and limiting costly downtime. In some areas of
the world, system certifications like NFPA 72 and ULC have specific requirements for UPS systems in the event
of an outage in order to provide continuous hazard protection during mitigation. The scope of these systems
can vary greatly, maintaining power to safety systems (flame and gas) is a priority and we often see them on
their own separate system. UPS systems can run in the tens of thousands of dollars. By significantly lowering
power load requirements, Net Safety instruments greatly reduce the cost associated with these systems and/or
increase the amount of mitigation time provided by these back-up power supplies. With Net Safety products you
can design a much smaller UPS system with greater stability and less maintenance.
Let's explore a typical UPS configuration at a Gas Compressor Station with about 5 Compressors. For this example application,
a standard installation would consist of about 10 LEL gas detectors, 20 H2S gas detectors, and 20 Triple IR flame detectors.

Next is remote locations, these sites will typically have one of three types of remote power generation:
Solar, TEG (thermo electric generators), or turbine/diesel engine. Each require careful analysis of power requirements in order
to prevent overloading the system and maintaining power to critical systems.
Engines and turbines are found at remote sites requiring larger power consumption levels. Total power draw is not as big of a factor here
but savings from the cost of generating the power for safety instruments and of course the wide voltage range provided by NSM products
is a huge advantage in these applications where power is more susceptible to fluctuation.
Solar packages on the otherhand have two primary considerations:
the number of solar arrays required to generate enough power for the application and the size of the battery systems needed to capture and store that power.
Only Net Safety products allow for the use of smaller, less expensive components. The table below outlines how Net Safety instruments can
greatly reduce costs when factored into the baseline design of a solar pacakge:

TEG systems are manufactured and have pre-determined power generation capabilities. The savings principle here is very simple because there is no flexibility with
the design of this power source - once again, utilizing the tremendous power consumption savings with Net Safety instruments greatly lowers cost and flexibility and provides
additional units on a smaller system if required.
