For Double Safety
The TVR1 door lock features double safety against breaking open and manipulation. Amongst others it is verified whether the closed door is really locked in the lock.
When actuating the emergency-open switch, the electromagnet integrated in the TVR becomes currentless. The bolt enters reliably, even with a load up to 3000 N already pressing on the door. Against breaking open from the outside the holding force of the bolt is 6000 N. Each door can be equipped with two TVR1 door locks at a maximum.
Installation
Generally the TVR1 locking unit is vertically inserted in the lateral frame of the door, the bolt being up. It can also be installed in the frame above the door, with the bolt showing downwards. The door lock requires about 85 mm in depth. It must be made sure that the gap between locking unit and striking plate is no less than 3 mm and no more than 5 mm.
Important: The TVR1 door lock should only be used on doors which are sufficiently solid. Only then the bolt will always reliably enter the opening in the striking plate and unbolt again. With light door constructions a winding or lowering door leaf may negatively influence the accurate functioning of the bolt.
