The DICTATOR S 400 signal control has been developed in particular to meet the requirements of the EN 14600:2005, point 4.9.2.1.
This norm requires that every closing of a fire protection door has to be announced by acoustic and optical warning signals - also during a power failure.

Together with the signal control DICTATOR provides the corresponding signallers, too.

Another product developed by DICTATOR especially for the preventive fire protection are the HLS temperature boltings. They are intended for their use on the type T 30 and T 60 hinged fire protection doors. They effectively prevent the forming of gaps when the door gets distorted by the heat of a fire.
