FAQ
Q. What makes PyrOptic so reliable?
A. PyrOnodes are thermal actuators which capture the expansion of an inert material to cut an optical fibre, this simplicity is how PyrOptic can guarantee long term reliability over decades of latency.
Q. Why cut the loop, what about a process sensor?
A.
Q. How is a loop repaired after activation?
A. Unlike glass fibre optic, joining plastic optical fibre requires no special training and can be achieved in under a minute using basic tools.
Q. How is the point of failure identified?
A. The most obvious sign is the detachment of the optical core at the activated PyrOnode.
Q. Can I put 500 sensors on one loop?
A. Yes, however remember an activation must be found. Optical loops are typically provided for each isolation zone. Because any repair work in response to alarm will require isolation of that zone there is no practical value knowing exactly which connection has failed prior to access.
Q. What is the correct temperature limit to select?
A. A PyrOnode with an activation temperature at or above the design temperature of the monitored connection should be used.
Q. Can PyrOptic be used for applications other than electrical connections?
A. PyrOptic is a temperature alarm suited to unlikely yet hazardous events, any activation temperature can be made from around 60°C to 110°C.

Q. Why cut the loop, what about a process sensor?
A.
- The vast majority of connections will not fail over an electrical installations life
- Temperature rise is only detectable in the end stages of connection failure
- A practical monitoring system must be economical, maintenance free and perform its function reliably, even after decades of latency
- To cut the optical loop thermal expansion must occur, energy from the failing connection is required to perform this physical transformation which eliminates false alarms
- A continuous optical loop is rugged and can monitor multiple points
- The optical loop provides MEMORY, over temperature events are captured between inspection intervals making periodic loop inspections highly effective
- Any system that relies on electronics for its function introduces complexity, the underlying reliability may be considerably less than the connections being monitored. As time progresses the probability of malfunction and false alarms increase. PyrOptic have received enquiries for the replacement of such systems after only 10 years of operation.
