Teledata Wireless Electromagnetic LockFDWD100

FDWD100 wireless electromagnetic door holder keeps fire doors in the open position and releases them upon alarm activation. Compatible with FDWE100 radio receivers via FDW2W. Enables door-holding scenarios in corridors where cabling cannot be run; it is the component that ensures fire compartmentation actually functions in historic buildings and structures closed to renovation. Upon alarm, power is cut and the door closes with its own closer.
