EFL Fusible Link

Fire Operation:

  • Uses Model J Fusible Link, a quick response standard fusible link
  • More consistent release temperatures compared to resetable bi-metal product
  • No external load on link, regardless of fire/smoke damper size
  • Faster response time by positioning fusible link in air-flow
  • Load applied on fusible link is part of EFL assembly

Smoke Operation:

EFL uses a S.P.D.T. switch for wiring a smoke detector. Upon smoke detector activation, the switch bypasses the fusible link and closes the damper, and remains closed until smoke signal stops. Listed by Underwriters Laboratories, Inc.
