Power source
The type of power used in a urinal with electronic components — for example, for automatic flushing.
— Batteries. The main advantage of such urinals is ease of installation — they do not require electricity supply from the network, which eliminates the difficulties of laying wires. However the operating time on one set of batteries is limited, and replaceable batteries usually have to be purchased separately. On the other hand, the electronic components of urinals are usually not particularly “gluttonous” in terms of energy consumption, so that the battery life period is often calculated not even in months, but in years.
— Network. Mains power is convenient because the user does not need to monitor the condition of the batteries and periodically change them — the electronics will work as long as there is voltage. The downside of these amenities is, first of all, some complexity in installation: you need not only to install a urinal, but also to make wiring. The second nuance is that when the electricity is turned off, the urinal can become completely useless.
In general, this option is especially convenient for plumbing used in public places — for example, toilets of train stations, shopping centers, etc.
— Network / batteries. Urinals capable of using both types of supply described above. Usually, in such devices, the main source of energy is the mains, and batteries are used as a backup option in case of power outages.
— Battery.../ generator. Quite an original option: a combination of a generator driven by a stream of water and a battery. In this case, the battery is the direct power source for the urinal electronics, while the generator is used to recharge it as needed. Thus, the power supply is completely autonomous, independent of the mains; and additional maintenance for such devices is practically not required (unlike the same battery-powered models — see above).
