Mortise burglar-resistant lock with fire protection

摘要

Mortise security lock with fire protection that combines passive and active safety. Passive safety is enhanced by using an alloy containing 72 to 76 wt%. Ni, 14 to 17 wt%. Cr, 6-10 wt.% Fe, 0.3 to 0.8% by weight. Mn and 0.05 to 0.11 wt%. C both for the latch bolt (1) and the bolt (2). Active safety is ensured electronics are located on the PCB (4) inserted into the lock body. Electronics includes a microprocessor containing internal memory, an acceleration sensor, temperature sensor and RF module that is using the RF antenna (3) connected wirelessly to an evaluation device. Microprocessor based on the response of the accelerator sensor evaluates data on the movement of the door and the data stored in its internal memory. It also evaluates data from temperature sensors on the potential of fire and stores this data in its internal memory and also sends them via RF modules and RF antenna (3) to an evaluation device, which informs the operator control room.
