The Accessible Virtual Keypad product (also known as BVA) is mainly designed to remotely activate buttons on the lift car operating panel through a Smartphone, avoiding its physical manipulation. Moreover, BVA helps universal accessibility of the lift through its App. The device can work with or without Internet connectivity. There are two versions of this product depending on the number of relays: BVA 12 relays and BVA 2 relays. BVA 12 relays is designed to be connected on buttons on lift car and BVA 2 relays, rear external buttons at each floor, even though both products may be swapped.
