INKA, IOR, REPO & LINK
3.7.3 Mains Failure
When the unit detects a mains failure, the unit will be powered from the internal backup-battery. INKA,
IOR and REPO can be configured to send a
mains failure alarm
when the mains power disappears.
Mains failure alarms will only be sent if the AC/DC adapter was connected and AC-power present
when the power switch of the unit was turned on.
To avoid radio interference when many units send a mains failure alarm at the same time, the time
from mains power loss to when the radio message is sent will be a random time between 0 and 45
seconds in intervals of 3 seconds.
The
mains failure
parameter is found in the
miscellaneous
section under the
preferences
tab in IOR
Programmer.

3.7.4 Mains return
When the AC power returns after a power failure, and the unit has sent a
mains failure alarm
, INKA,
IOR and REPO can be configured to send a
mains OK indication
.
To avoid radio interference when many units send a mains OK indication at the same time, the time
from mains power return to when the radio message is sent will be a random time between 0 and 45
seconds in intervals of 3 seconds.
