8.1 Battery warning and battery replacement when SREL.BAT is used
A SmartRelay can emit a battery warning as follows when the battery
capacity is depleted:

SREL, SREL.ZK and SREL.ADV

Inside LED flashes 8x each time a transponder is used and before
the SmartRelay switches.

This LED should be visible from the outside in the case of battery-
powered operation.

SREL.ADV only

External LED flashes 8 times or external buzzer beeps 8 times
whenever a transponder is used.
IMPORTANT
Around another 100 activations are possible after a battery warning.
Transponder battery must be replaced as soon as possible.
8.2 Backup battery
A discharged backup battery may lead to the internal clock stopping in
SmartRelays. We therefore recommend checking the time on the clock at
regular intervals. A backup battery will last for about ten years if the power
supply to the SmartRelay is not interrupted. This battery should be
replaced on a periodical basis if SmartRelay draws on the backup battery
at regular intervals due to frequent power failures.
IMPORTANT
The backup battery must not be used if SmartRelay is powered by a bat-
tery (SREL.BAT).
