TSZ RZ-24
TSZ RZ-24 Magnetic Door Holder Panel
The magnetic door holder panel TSZ RZ-24 with integrated push button for manual release is intended for the control of classified fire doors, fire gates and fire dampers by means of hold-open devices. If a fire detector should detect smoke or heat or if a manual call point is activated, the TSZ RZ-24 interrupts the power supply to the holding solenoids immediately, and the fire doors are automatically closed by the door closer. Simultaneously, the relay contact opens and possibly connected signal devices or controls are activated. PN: 931974
