Product Introduction

The HS-EV161 elevator voice control expansion board is a relay expansion board used in conjunction with the HS-EV160 voice control board. It is mainly used for elevator floor button control output that requires multi-channel switch control. The control output board on this floor adopts a hand in hand control output method, which avoids the problem of large circuit board size and space occupation caused by multiple control buttons. Users can choose the number of expansion panels based on their floor number, reducing installation costs for users.

Product Features

Support arbitrary combinations to meet the diverse user needs of residential areas, office buildings, hospitals, and other floors. Users only need to toggle the dip switch on the expansion board to select the number of combined floors. The specific corresponding control dialing numbers are as follows:

K0	K1	K2	Controlled floor number
1	0	0	Alarm, open door, close door, negative 3rd floor, negative 2nd floor, negative 1st floor, 1st floor to 10th floor.
0	1	0	11th to 26th floors.
1	1	0	27th to 39th floors.

Attention: For more floor controls, please contact customer service for customization.
