Functional testing
Inspection must at least include the following aspects:
Interaction of all devices and their correct technical condition must be verified.
The fire protection flap / smoke protection flap and/or the ventilator must
switch into safety position "closed and/or off" and remain in that position, if
–
Smoke is detected
–
A fault occurs at the smoke switch
(e.g. due to removal of the smoke switch from the base)
–
The energy supply fails/returns
–
The manual actuation pushbutton is pressed
For testing of smoke detection the test aerosol 918/5 should be used. The test
aerosol is free from halogenated hydrocarbons (CFC and the like). If a smoke
switch does not react to, i.e. is not triggered by this test, it must be replaced.
The inlet openings at the inlet tube of the LRS 04 Ex must be kept unblocked.
