The SafeRoute STV-A is an adapter for insertion into the door frame. Using this adapter, the TV 100, TV 200, TV 500 and TV 550 analogue locking devices without DCW® interface can be integrated into SafeRoute. The integration of suitable products from other manufacturers in accordance with the EltVTR (German directive for electrical locking systems on escape route doors)/EN 13637 is also possible (observe corresponding approvals and certificates). Among other things, the module can also be used for querying the status of other locking elements, e.g. gates.
