## Long description

DAHUA ASF921 panic button is a wall-mounted emergency switch intended for alarm and access control systems. The device comes in a compact green plastic housing measuring 86×86×50 mm and is designed to provide a clearly visible, manually operated trigger for alarms or emergency signals in commercial and residential installations. The mechanical operation is simple and the housing uses fire-retardant material to meet safety requirements.
Advantages
The panic button uses photoelectric control technology to reduce the risk of mechanical failure and prolong service life. It supports normally open and normally closed contact configurations, allowing flexible integration into different alarm and access control circuits. The unit has passed extensive fatigue testing and is specified for high durability. Its compact dimensions and standard wall-mount format make installation straightforward in a variety of locations.

How to use
