- System
- Addressable fire alarm
The Dahua DHI-HY-1221 emergency release and abort button gives a person control over gas or powder suppression automation. One function releases the extinguishing agent immediately, the other blocks it if people are still inside the protected room. Both buttons are mandatory for automatic suppression zones.
Advantages
- Manual release when the fire is spotted before automatic detection reacts
- Abort function — protection for people who have not yet left the room
- Addressable: the panel records which point was used and what action was taken
- Supervision of the device and its communication line
- Clear function marking that remains readable under stress
Applications
- Server rooms and equipment rooms with gas suppression
- Archives, vaults and rooms holding valuables
- Electrical switchrooms and areas with power equipment
- Process zones with automatic suppression installations
Frequently asked questions
Where is the abort button placed?
At the entrance to the protected room, so that anyone going inside can stop the release before entering the discharge area.
How much time is allowed for evacuation before the gas is released?
The delay is set during commissioning based on room area and the time needed for people to leave. The value is agreed with the design.
Can the system work without such a button?
For automatic suppression zones, manual control and abort are a mandatory part of the system.
