I have the qolsys panel 4 ( migrated from an older version). I have a lot of smoke alarms primarily PG9936, Diligently, I replaced all of the batteries in all of the alarms ( several fresh packs). Now, at least 3 of alarms began issuing low battery warning. The b atteries were good and when we swapped them with another set, all is OK. Fortuately, they did not go off at 2 AM when most do. None of the alarms are past their date. Any ideas?
Just to be sure what brand and type of batteries are being used?
The PG9936 specifies Duracell Procell Alkaline or Energizer E92 Alkaline batteries. If a lithium or rechargeable battery is used, or a battery with different charge characteristics it can cause issues.
Also just to clarify, all of the batteries were replaced on each one right? If an older battery is mixed in it will cause issues. If you are using the same brand that comes with the detectors, is it possible that some got mixed up?
all new energizers Max which are e92 I only use energizer and the procell. All are brand new and when I replace, I discard the old ones.
Hmm, it’s always possible to have a bad battery here and there, but at least 3 seems odd unless the batteries were old and sitting on the shelf for a long time.
Did you just replace the batteries again on those? I am not seeing any low battery statuses currently.
How long after changing the batteries originally did they report low again? Can you confirm the names of the sensors this occurred on?
I replaced every one. The batteries I purchased from amazon so they are fairly new and we tested them. RIght now sensor 20 is not showing a low battery I will replace it since 1) the qolsys panel beeps incesssantly and 2) our parrot enjoys mimicking the sound of the smoke detector chirp
Currently, the only sensor showing an issue is Zone 48 living room right which I don’t believe it is a smoke since it is programmed as an entry exit sensor.
All smoked on your account look fine. Could another 110VAC smoke be beeping or possibly a local CO detector?
What is showing low battery on your IQ panel?
I think I figured out the problem. The energizer batteries had a shelf expiration of 2036 and showed “good” on the regular cheap battery tester. However, I checked the actual voltage under load and is showed @ 1.3 volts for the batteries that I replaced wth duracell. The duracells showed 1.5 volts and all was good. I don’t cheap out with SD batteries but I will do a more thorough test of each battery before changing. I have a multimeter but this one is easy KKEANIC Battery Tester SL-049 - Professional Digital Battery Checker with LCD Display for Household AA, AAA, AAAA,C, D, 9V, Button Cells.

Thw beeping in the alarm panel is highly annoying so I change rignt away.
yes, zone 48 is an exit/entry that I need to replace.
