Fire access control system is how to linkage
Hard linkage, that is, through hardware to achieve linkage. The fire alarm signal of the hardware interface to access the door to open the door button, when the fire alarm has been triggered, it is equivalent to the door has been a signal to open the door, so that the door automatically open, people can easily through the door.
Now the new specification has been the implementation of the whole building lighting, that is, the whole building evacuation. So any two points when the alarm system can be fully released, you can access the system through a total signal, you can also on-site control, are generally power.
The fire does not control the access control, the linkage when the direct access to the power of access control, access control can be opened
To achieve soft linkage, that is, through the software to achieve linkage, when the fire alarm system received the alarm signal, through the software, the command issued to access real-time monitoring software online, so that the controller into a normally open state. But the difficulty of this realization is the need to fire software and access control software to do an integration, we need to open their own system interface protocol.
