SECURITY DEVICE AND SECURITY SYSTEM USING THE SAME

摘要

The present invention relates to a security device used in connection with an access barrier of a protected area. The access barrier is movable between an open position and a closed position for selectively permitting ingress and egress to the protected area. The device has an access barrier position detector to detect the position of the access barrier and generate a status signal indicative of the access barrier being open or closed. The device also has a lock position detector to detect the position of a lock for selectively locking and unlocking the access barrier and generate a status signal indicative of the access barrier being locked or unlocked. A signal transmitter is provided to transmit the status signals.
