held.

Note 1 *ALM are the signals of active low.
After the power is supplied to the controller, they are usually ON and turned
OFF when an error is detected. If the alarm is generated, it will be necessary
to absolute reset after the battery replacement. (The controller checks the
battery voltage at the time the power is supplied. The controller would not
detect it even if the battery voltage is decreased to the alarm level while it is
on.)
(Note) It is necessary to have the absolute reset to cancel the alarm.
