LCN 4040SE Series Door Closer Arms

Importance of LCN 4040SE Door Closer Arms

The 4040SE Door Closer Arms play a crucial role in:

• Fire and Smoke Control: They keep fire and smoke barrier doors open for convenience but automatically release and close the door when triggered by a fire alarm or power interruption, helping to contain smoke and flames and maintain building safety.
• Code Compliance: These closers are UL-listed for smoke barriers and fire doors and conform to life safety codes, such as NFPA 101, making them an essential component for facilities that require strict adherence to safety regulations.
• Versatility: Suitable for a wide range of commercial applications, including schools, hospitals, and office buildings, where both accessibility and emergency preparedness are critical.
