Primex prioritizes maintaining the highest quality product while managing security, component availability, and cost. Individual sensors are highly technical products, containing local memory to store readings, generate local alarms, run the local display, as well as network and power management components.
Our engineering and operations teams constantly watch for supply chain challenges, while also looking to optimize product performance and quality through new and emerging technology. This approach leads to a perpetual evolution of the technology within the platform and can make maintaining these devices over the course of their evolution a challenge. Within our current generation of sensors (if your sensor has 2 small grey buttons, it’s the current generation), we have been highly successful at maintaining devices beyond 5 years by using a very robust change control process that ensures that all current standards of quality and performance are maintained when design changes are executed and, when needed,
over-the-air (OTA) upgrades are carried out. All of these changes are carefully evaluated, reviewed, tested, and approved before introduction.
While we try to minimize these changes, we have implemented as many as 25 changes over the course of some years, depending on the level of volatility and/or innovation within the electronic components market. Given the pace of these changes and feedback from the field, we estimate our sensor’s useful life to be 3-4 years, though the factors that define that life are, by their very nature, unpredictable.
For example, we updated our radio in October 2017, and again in July 2021. For sensors installed before the July 2021 change, we are not able to offer OTA updates, so these sensors require replacement if we have issues with customer network
In summary, due to the nature of this constantly evolving technology and the complexity of the ecosystem, the viability of the devices is finite. Subscribing to hardware assurance in the Advanced or Preferred OneVue plans allows Primex to manage the risk of replacing your sensors as needed rather than having customers manage the risk of failure and large capital expenses.
The following manuals are for those responsible for installing and operating Primex sensors.
