Remotely operated function test

Conforms to standardsEmergency call devices for lifts must be checked regularlyand checked for their function. Here comes theSpecial feature of the SCHAEFER emergency call button fb into play: the buttonscan be "pressed" via remote access (remote control) andcan thus be tested for their mechanical and electrical operabilitybe checked.

Integrated in aEmergency call simulation system, the push-buttons are automatically and inat defined intervals. Thanks to this technologyPersonnel and service costs for a manual on-site inspectioncan be saved. The possibility of the system the elevator emergency callautomatic and permanent monitoring, also contributes to theOperational safety of the elevator system.
