Replacement & Compatibility FAQ
Q: Is the EASYGEN-3500-5 a direct replacement for the EASYGEN-3500-4?
A: They are in the same series but differ in I/O configuration. Verify your wiring diagram and I/O requirements before substituting.
Q: Can I use a ComAp InteliGen 200 as a replacement?
A: Functionally similar, but requires full parameter remapping, wiring adaptation, and recommissioning. Not a drop-in replacement.
Q: Do you supply new or refurbished units?
A: We supply both new-in-box and tested surplus units. Condition is clearly stated in the quotation.
Q: What is the warranty?
A: 12-month warranty on all units. Contact support for warranty claim procedures.
