3.1 Power supply:
Advice regarding batteries:
We advise you to use normal alkaline batteries of high quality for the indoor unit. Alkaline batteries with
a capacity of 2000mAh have a lifespan of over one year. Rechargeable batteries are not recommended
because of their lower supply voltage.
Also the outdoor unit is powered by 3 AA 1.5Volt batteries, but because normal Alkaline batteries
perform poorly or not at all at temperatures of around or below 0°C, it’s not recommended to use
standard Alkaline batteries for the outdoor unit.
For that reason, we advise you to use Lithium batteries for the outdoor unit that are designed to function
well within a temperature range of -20°C to 60°C. These batteries can be ordered via the service
department of Alecto via telephone number 073 6411 355 (Netherlands) or 03 238 5666 (Belgium) or via
internet: www.alecto.info
Lithium batteries with a capacity of 2900mAh have a lifespan of over one year.
