Here is the question I posed to ELK:
" If a sensor goes offline for any reason (signal loss, device issue, tampering or blocking of signal), what is the maximum amount of time that can pass before the base station notices that the sensor is gone and is no longer able to report its state back to the base station."
And here is the information I received from ELK about their wireless sensors:
"The “Supervisory Check-in Time Interval” is hardcoded at ~64 minutes. For NON-Fire sensors we’d recommend the Time Window be set to 24 hours meaning the sensor has 24 hours to check in a certain number of times (proprietary settings) before the M1 assumes the sensor has good missing. "
Honestly, this is after 2 emails explaining what I was looking for and that response is no more clear than the first one to say the least. It looks like the sensors try to check-in every 64 minutes but if they can't check-in, oh well, we will try again later, no big deal, its not like you were depending on that sensor to do something right? LOL
Can you please provide sources? Brad from ELK tech support did not give me the same answer.
Currently, it looks like ELK is 6x as expensive for a "Professional System" that seems to have equal or worse supervisory check-in rates to that of a $200 Ring system.
