【Yupiteru Serial Backup Siren Replacement｜Regular Maintenance for Car Security】

When you use car security for a long time, the battery inside the siren gradually wears out.

Yupiteru’s serial backup siren is a security siren that can continue operating with its built-in battery even if power is not supplied from the vehicle’s main battery. It also plays a role in notifying the surroundings of abnormalities when there is an issue with the vehicle’s power supply.

However, the built-in battery is a consumable item. Depending on the operating environment, the typical replacement interval is about 3 to 5 years. If several years have passed, or if you feel the sound of operation is weaker than before, it’s reassuring to consider replacing it in preparation for emergencies.

Important Points When Replacing

The serial backup siren is a dedicated part designed to be used in combination with Yupiteru car security systems.

Not only do we replace the part—we also confirm the combination and condition with the security installed in the vehicle, and after replacement, we check whether the entire system operates normally. Since the points to be checked vary depending on the existing installation details and the vehicle’s condition, we guide you with accurate information while viewing the actual vehicle.

Security is maintained not only by its conspicuous functions, but also by ensuring that these backup parts work properly. If it were my car, I would check not only the siren but also the condition of the entire system on a vehicle that has been used for many years.

If you are considering a replacement, please share information about the Yupiteru security system you are currently using and, as far as you know, the installation timing. Let’s sort out the necessary maintenance together while confirming the vehicle’s condition.
