Figure 9. GND EFL Models Come Pre-wired for Assembly.
NOTE:
The GND models pre-wired for assembly with the EFL (GNDxxx.1U/F) will only operate when an EFL,
(ASK79.xxx) is attached.
Maintenance
CAUTION:
The GND 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.
Electronic Fusible Link (EFL)
Versions GNDxxx.1U/F contain wire with a Molex connector (See Figure 9) to accommodate an EFL.
EFLs are purchased separately. See Table 1.
