The Dahua DHI-HY-A0321 addressable manual call point is a hand-operated alarm device for HY-series addressable systems. It lets anyone who spots a fire start the alarm and trigger the evacuation scenario without waiting for automatic detectors to react — sometimes that is a difference of several minutes.
Advantages
- Immediate alarm raised by the person who noticed the fire
- Individual address: the panel shows the exact point of activation
- Continuous diagnostics of the device and the line
- Simple, self-explanatory activation with no instructions needed
- Works in the same loop as automatic detectors
Applications
- Corridors, lobbies and escape exits
- Workshops and warehouse areas with staff
- Educational and medical institutions
- Hotels and buildings with large numbers of people
Frequently asked questions
How many manual call points does a floor need?
Spacing is regulated by the distance to the nearest device along escape routes. The layout is prepared by the designer.
What happens after it is pressed?
The panel receives the alarm, sounds the evacuation warning and runs the configured scenarios — smoke extraction, exit release, ventilation shutdown.
Is a base required for installation?
The supplied set depends on the version. We deliver the device together with the mounting parts it needs.
