Specific Commissioning and
Servicing Requirements
Motors for Smoke Extract Fans

o
C for 120 minutes.
These motors are used to provide a SAFETY FUNCTION for
people in the event of fire in public premises
:
they are therefore subject to strict constraints concerning
their operating and maintenance.
Operating constraints
i. Check on the nameplate that the selected motor corresponds
to the maximum exposure temperature and duration.
ii. Non ventilated motors MUST be placed in the airflow from
the driven fan. Ventilated motors can be placed outside the
flow.
iii.
AFTER THE MOTOR HAS BEEN SUBJECTED TO ONE
EMERGENCY DUTY OPERATION, IT MUST BE REPLACED.
iv. With variable speed control. Ensure that the maximum speed
never exceeds the speed of the motor supplied by the mains
and that the delivered power corresponds to the previous
definitions.
These qualifications ensure the qualification of the driven
fan by the manufacturer.
