I need a SME to validate my assumptions and thinking for my smokes. I am comfortable learning on the fly with physical security but the fire sensors I want to make sure I do right.
The IQ Pro replaced an Silent Knight 2605 hardwired system w/ System Sensor 4WT-B fire sensors (see pics below). I’ve got all the wires from the old system labeled.
Assumptions that need validation…
Existing hardwired smokes are wired up to plug and play. Meaning they are all likely in one zone (can I test this easily?) and work in series. Semi-validated using LLM. Existing hardware module labeled 0192 Detection Systems is a fault detector and should stay as is.
I can swap my existing hardwired smokes (previously wired to 13 and 14 on Silent Knight( to a SINGLE zone (two wires only) on the IQ Pro. The panel will power them using the low voltage panel input. Is this valid? Can I test them by just plugging in and powering up the board? I believe I need at least partial wired smokes in my area but TBD IANAL.
I should not attempt to reuse old sensors and replace with wireless PowerG for physical security (motion, door, window etc.).
New smokes should all be wireless, hardwire is not worth the effort unless already in place.
Yes, you can connect the smokes to the IQ Pro to test the smoke detectors. You will need to replace the end of the line resistor with one provided by the new panel so the system wont be in trouble.
I cannot find the 0192 Detection System manual. Is there another part number on the device? Can you share the wiring of this device?
Yes, to correctly power the smoke detectors, you have to enable PGM2 as system reset and program a hardwire zone as fire.
You can replace with wireless but the wires should last a very long time. The parts you most likely will need to replace are motion detectors followed by door and window sensors.
Looking at the picture you sent, 5074 means it was made in the 4th week of July in either 2015 or 2025. Fire devices should be replaces every 10 years.
I believe if your wiring is till good, hardwire is better than wireless to avoid replacing batteries. If your wire is damaged and you cant repair, wireless would be the way to go
@vidail thank you so much! Ok, this gives me more confidence.

Detection Systems Inc. (DSI) EOL-200 / “End of Line”-200. Unable to find the manual but see references to it in other documentation.
Yes, to correctly power the smoke detectors, you have to enable PGM2 as system reset and program a hardwire zone as fire. I will look into this in the manual, thank you.

Do you have any wired sensors I could easily rip and replace and use the wire infra? Whats best practices for tracing/fox hound sensors back to panel?
Looking at the picture you sent, 5074 means it was made in the 4th week of July in either 2015 or 2025. Fire devices should be replaces every 10 years. Does your team have a recommended sensor I can use to replace in kind (with modern tech)? System Sensor 4WTAR-B?
Any guidance on how I chose which resister to use (am I dumb, are they all the same?) Reading this, it looks like I can only use SEOL resistor for Fire, correct?
An RM-2 supervisory relay is recommended incase there is a loss of power on the smoke detectors. For other devices, you can use any resistor between 1-10k however, a 5.6k resistor is needed for UL installations.
Wiring the smokes and RM-2 are in the diagram below.
The system sensors brand makes reliable smoked that you wont have many issues with. It looks like it is the same brand you have installed based on the pictures above.
