So, I checked the quick guide that came with Hardwire 8 wireless translater, and it’s actually even older - from 2015. There was no mention of the 4.7k Ohm resistor, or the UL resistor mode. However, interestingly, the Processor LED blinks at the rate of 8x/sec - just as described for the Hardwire 16-F working in the default/UL resistor mode (as opposed to 1x/sec for the normal 1k-10k Ohm EOL resistor mode).
At any rate, I proceeded as follows:
1.) Unenrolled the sensor
2.) Removed the original 3.3k Ohm resistor and replaced it with a 4.7k Ohm resistor (wired in parallel)
3.) Performed a memory reset on the Hardware 8
4.) Ensured that the N/O float switch was Opened
5.) Learned the sensor into that zone by filling the basin and causing the N/O float switch to Close
Afterwards, the behavior on the Hardware 8 seems consistently normal. The zone LED is always out when the N/O float switch is Open, and lit solid when the N/O float switch is Closed (before the LED would blink and indicate Tamper when Closed). No indications of Tamper at all.
I learned it in as a Water sensor | Other Flood, as I did yesterday. Oddly, despite the Hardware 8’s zone LED indicating properly, general indications on the panel and in the ADC app did not appear to reflect any changes.
Specifically, while N/O float switch is OPEN (normal), I get the following indications:
-Zone LED: Not lit
-ADC App: Indicates “Dry”
-Panel | Home: Closed/Inactive icon
-Panel | Sensor Status: Normal
While N/O float switch is CLOSED (alarm condition), I get the following indications:
-Zone LED: Lit
-ADC App: Indicates “Dry”
-Panel | Home: Closed/Inactive icon
-Panel | Sensor Status: Normal
The panel alarms upon transition, either from opened to closed, or closed to open, which I wouldn’t think is normal.
I haven’t seen any further Tamper alarms. However, at 7:30pm I did get a false flood alarm (basin was dry, and I wasn’t even home). I changed the sensor type from Water | Other Flood to Water | IQ. I haven’t retested yet in this configuration, but I did not get a subsequent alarm at 8:30pm, nor even at 9:30pm. I haven’t functionally tested this configuration yet, and am powering it down the night, just in case of false alarms.
I wonder if the alarm and software indication inconsistencies that I’m currently seeing might just be due to incorrect sensor type configuration that needed to be adjusted (either on my end, or Surety’s end…?). Or perhaps what I have now is correct and merely needs to be retested for confirmation. Please let me know what you think, and next steps. Current sensor’s name is “Grinder Pump Basin”.
