Can the controller of the access control system be placed in the engine room?
Look at the specific situation of the scene, not to say that the release room like, according to the scene to set, such as on-site permitting, on the centralized management of the power supply room is also more convenient.
To put the controller on the engine room, there must be a prerequisite, that is, the distance between the reader and the controller, in general, WG26 / 34 card reader transmission distance is 150 meters, if you exceed this distance, then On the engine room controller to receive no data, in other words that your access control system failure, so in general, depends on the specific circumstances, if it is a number of access control, then the controller and controller The distance is greater than 150 meters, it is best to use the controller, the controller through the 485 or TCP communication to connect, connect the computer unified management.
Can be; generally placed near the door, the communication (RS485) bus and the engine room control host connection, if it is using the network communication access controller, as long as the host computer network can be network communication control; the controller on the engine room, Resulting in wiring inconvenience, the reader to the access controller from the distance should be less than 150 meters.
