I have a wireless motion sensor that had a low battery. I replaced battery and entered C-O-D-E + off (twice) which is supposed to clear the message of "check 15". But it won't go away and i have to bypass that zone at night to alarm system. Anyone know how to clear that error message.:wall:

Check the battery cover. If the tamper switch is not closing properly it won't clear. Also, check that battery, because they have a long shelf life, some vendors don't rotate their stock as they should. I've often gotten these lithium batteries that were past their prime.
