I have 3 ea. 2GIG-SMKT3-345 installed for about 2 years now.
The one closest to the panel has been throwing a “malfuntion” error where it shows up and beeps on my Go Panel. This happens about every 2 weeks, but randomly and not at a set interval.
Last night I took it down and didn’t notice anything strange. I blew everything with air to try and clean.
My question is why do you think it is doing this? If the batteries were low, would it distinguish that with a low battery specific message?
Prior to malfunction are you getting a yellow led blinking? If functioning properly, green led blinks every 12 seconds…
Yellow led blinks every 8 seconds: contamination (dirty)
Fix: clean, or replace
Yellow led blinks every 4 seconds: general fault
Fix: replace
Yellow led blinks every 12 seconds: low battery
Fix: replace batteries
Also, do a walk test and test the smkt3…how many bars out of 5? Are the bars green?
If bars are not green, signal is weak, and is causing loss of supervision malfunctions. Relocate panel, and retest. Does green led now blink every 12 seconds? Does walk test now show green bars?
It would be so hard to determine that due to the long time spans between malfunction (weeks) and the random nature. I don’t know ti malfunctions until the panel alerts me.
K. Sounds like your SMKT2 is OK for sensitivity, and signal. When was the last time you properly tested it? (And I do not mean via “test” button. I mean an actual functional device test)
Next time when it goes into malfunction pay attention to diagnostic LEDs. The smkt2 does periodic self tests, if it fails a test, it reports the malfunction to the panel. I think that is what you are seeing. Dirty/contamination, or other issue.
I think your smkt2 is borderline, and is close to failure. If it keeps doing it, I would replace it.
