How is the access control system and the fire control system linked?
The first is 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.
These two ways have their own advantages and disadvantages: the software linkage is the easiest, you can reduce the excess wiring, can be more beautiful, can be a good cost control, but the need for a system open interface agreement, this small access control is impossible to achieve of.
The second is a 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.
