Variants – record DFA 127 FULL POWER
record DFA 127 FIRE
Closes reliably in case of fire
The record DFA 127 FIRE is approved for use as a smoke and fire protection door. In case of fire, a signal from the smoke and heat detector or fire alarm system immediately triggers the safe closing of the passage. Closing takes place by spring force. The record SFR 127’s mechanical sequential control also enables double leaf fire doors to be used.
record DFA 127 INVERSE
Opens without mains power
The record DFA 127 INVERSE enables doors to open securely and reliably, even without a power supply. During the motor-driven closing cycle, the energy required for opening is mechanically stored using a spring. Should smoke start to fill the building, the independent smoke and heat venting system controls the drive, and the record DFA 127 INVERSE opens reliably, even during power failures. The door can therefore be used to allow fresh air to circulate inside buildings, or to vent smoke and heat.
record DFA 127 LOW ENERGY
With reduced motion energy
The record DFA 127 LOW ENERGY is the ideal drive for environments where people move only slowly and have limited reaction capacity, such as hospitals and nursing homes. Kinetic energy (movement power) is limited to 1.6 joules, which means the safety of people in the swing area, even in the absence of additional security sensors, is not compromised. This door is the ideal choice where safe opening or access assistance is required.
