Brake monitor (100) for monitoring a brake system (13) of an elevator system (10) that comprises a drive (11) and a drive controller (12) in addition to the brake system (13). The brake monitor (100) comprises a first brake signal input (KB) for electrically connecting the brake monitor (100) to a first brake contact of the brake system (13). The brake monitor further comprises a driving signal input (AF) for connecting the brake monitor (100) to a first electrical driving signal line (12.1) of the drive controller (12). Also provided are a power supply (101), a microprocessor (102) and a relay circuit (103). The relay circuit (103) is configured such that it can be activated for interrupting a safety circuit (20) of the elevator system (10) or for interrupting a control voltage of the drive controller (12) so that the elevator system (10) can be stopped.

Linvention concerne un dispositif de contrôle de freinage (100) destiné à surveiller un système de freinage (13) dune installation dascenseur (10) qui présente en plus du système de freinage (13) un entraînement (11) et une commande dentraînement (12). Le dispositif de contrôle de freinage (100) comprend une première entrée de signal de freinage (KB), afin de relier électriquement le dispositif de contrôle de freinage (100) à un premier contact de freinage du système de freinage (13). En outre, il comprend une entrée de signal de marche (AF), afin de relier le dispositif de contrôle de freinage (100) à une première ligne de signal de marche électrique (12.1) de la commande dentraînement (12). Le dispositif de contrôle de freinage comprend en outre une alimentation en courant (101), un microprocesseur (102) et un circuit de relais (103). Le circuit de relais (103) est câblé de manière à pouvoir être activé afin de couper un circuit de sécurité (20) de linstallation dascenseur (10) ou une tension de commande de la commande dentraînement (12) et de mettre ainsi linstallation dascenseur (10) hors service.
