NOTE:
All EFLs are low voltage and do not need to be
wired in conduit.
To install an EFL, do the following:
1. Remove and discard the cover marked EFL.
2. Use a small, needle-nose pliers to squeeze the
release lock of the jumper plug and remove the
jumper plug.
NOTE: Remove the entire jumper plug, including
the wire loop.
3. Insert the quick connect plug from the EFL and
ensure that the cable is secure.
NOTE:
If you are not using an EFL, do not modify the
actuator. An EFL or jumper plug must be installed for
actuator to work properly.
Maintenance
CAUTION:
The GRD actuator does not require any
periodic cycling to function properly as an
integral part of an active smoke control
damper system. The National Fire Alarm
Code NFPA 72 states that all life safety
systems are to be functionally checked at
least annually. Check the smoke control
damper/actuator every time you functionally
check your smoke detectors, emergency
lights, and/or power generators for operation.
