INITIAL START-UP
After completing the works described in points from 4 to 8 (type and number of operations
depends on the product configuration), connecting the actuator to the power source and tidying up
the space around the vent, you may proceed to a trial run and the first full opening of the leaf.
To do so:
a) For electric control - trigger an alarm from the RPO-1 emergency pushbutton, smoke detector
or fire alarm system (SAP, SSP).
b) For pneumatic control - trigger the alarm from pneumatic alarm box type AK or fire alarm
system (SAP, SSP).
Regardless of the opening system used, it is imperative to:
1)
Measure the time to open the vent leaf to the smoke exhaust position.
The correct leaf opening time should be up to 60 s.
2)
Measure the opening angle of the vent leaf to the smoke position.
The correct opening angle for smoke exhaust should be at least 140°.
3)
Verify the presence of the product nameplate at the location shown in Fig. 70.
If the hold-open time is exceeded or the hold-open angle is too small, verify the type of leaf glazing
and actuator installed against the specifications on the nameplate, and:
a)
For electric control - measure voltage value of actuator supply line.
b)
For pneumatic control - verify the value of supply pressure or the size of CO

used.
