Note:
If the system operation deviates from the requirements of the "Fire Incident Development
Scenario" for a specific building/system, the following checks should be carried out:
1.
It has been activated. In case the device has not been activated, it is necessary to start
service activities, based on the device's technical documentation, aimed at diagnosing and
removing failures.
2.
Check the "Correct operation
”
signal transmitted to the Fire Alarm System. In case the
signal is not forwarded by the unit, it is necessary to start service activities, based on the
device's technical documentation, aimed at diagnosing and removing faults.
3.
Check the activation of the aeration fan (frequency inverter) 15 seconds after trigerring. In
case the aeration unit is not activated, it is necessary to start service activities, based on
the device's technical documentation, aimed at diagnosing and removing failures.
4.
Check the indications of the differential pressure values between the protected space and
the reference space on the hold overpressure display on the TSS panel. Where all doors to
the protected space are closed (not applicable to lift shafts), the pressure indication shall
be in accordance with the design guidelines for the facility. In case of lack of stable
pressure value on the display, it is necessary to start service activities, based on the
device's technical documentation, aimed at diagnosing and removing faults. If an MSPU is
installed, the pressure values are displayed on the monitor screen in the visualization
program.
5.
Check the condition of the shut-off damper. Approximately one hundred and fifty seconds
after the aeration fan has been switched off, the shut-off damper goes into the fully closed
position. In case of no return to such state, it is necessary to start service activities, based
on the device's technical documentation, aimed at diagnosing and removing faults.

12.1. General provisions
The design recommendations given in this document assume that pressure differential systems
are designed to overcome both the pressures of the chimney effect caused by non-pressurised
shafts elsewhere in the building and the differences caused by wind.
