Elk M1g randomly rebooted....

Today my wife got home and went to disarm the system and she said the keypad went blank with 14 seconds remaining on it. It then came back almost immediately and (she believes it said something about F4, F5 or F11 on the display but dosent remember) and then it alarmed...

Dan I PMd you the log information so it can be debugged but there is no information I can see in it to be useful..

Are you sure the ELK M1 rebooted?

Mine has done something similar, but it was static electricity that took out the keypad and the keypad lost communication and "rebooted", but the elk and all the other keypads where unaffected, except of course, the countdown continued with no way to stop it without running to another keypad.

Ah-ho--static electricity, huh?

Do you really think it's better to ground the keypad...? This is kind of strange since Elk doesn't recommend grounding the Elk M1 Gold and the keypad...

Something caused the processor in the keypad to "latch up". It could have been a static zap. The hardware watchdog circuit kicked in and reset the keypad processor. The log shows a "keypad system reset".

Don't let anyone tell you otherwise, microprocessor's CAN and WILL "latch up" from time to time. Without a hardware watchdog circuit, the power must be removed for a few seconds and restored to bring it back to life. A "latched up" processor may start overheating and destroy itself if the "latch up" is not cleared within a short period of time. All this is taken care of by the "Hardware Watchdog Monitor" on each module in the M1 system.

Well, I did not know that...

So, if this happens again, I'd go to another keypad to disarm the system, but I only have one keypad...

thanks for the information on the "reboot" no need to preach to me about the problems static causes.... But she swears she did not touch the keypad just opened the door, and any static jumping that far I would suppose she would feel. Maybe it just realized it was locked up when it was counting down and not just sitting.... hmmm don't know as long as you believe it is OK I'm fine with that as it is working fine now...

Maybe I should just bring the static simulator home from work and see how bad it really is... You'd replace it on it's warranty right with a KP2 perhaps? :lol:
