Commissioning

3.2

Testing to detectors and manual activations

All the installed detectors must be tested during the commissioning phase. It is necessary to check the capacity of each
detector to react to a simulated condition of fire, and to check the precision of the signals transmitted to the control
panel in response to its activation (description of the point and zone).

For this purpose it is possible to use the

Test

button of the control panel (

[A]

)

on the “Zone status” screen, accessible via the “System status” menu on the
home page.

By tapping this button it is possible to place one or more zones in test status.
The activation of a detector which belongs to a zone in test status will not
generate any alarm signalling or activate the outputs or signalling devices.
However, the control panel will activate the signalling LEDs on the detectors
and will perform automatic reset after a few seconds without any need of
further intervention by the operator on the control panel.

The activation of a point which belongs to a zone in test status will be recorded in the events log. Therefore, on
completion of the test on all the zone devices, the operator can check the congruence of the various indications by
means of the log.

The activation of all the manual call points (alarm buttons) must be tested in the same way as described for the detectors.

3.3

Testing signalling and activations

The functionality and efficiency of all the signalling devices must be checked
thoroughly.

It is possible to test such devices by activating the relative LEDs and outputs
manually at the control panel via the respective management page (

[B]

To reach this page you must access the “Points” section via the “System
status” menu on the homepage. Select the desired loop and point to be
tested from the lists shown then, by means of the relative

View

buttons go

to the management screen where you will find the

Turn On output

and

Turn

On LED

buttons.

Note:

Testing devices by means of manual activation does not test functionality and efficiency of the cause/
effect association which determines their activation (programming coherence of groups), therefore, it is
necessary to perform real functionality tests.

3.4

Testing the extinction system

Particular attention must be paid to the testing of eventual fire extinction systems.

Special attention must be paid to the functionality and safety of the extinguishing-agent release devices before
proceeding with the testing of all activation and stop-extinction procedures in accordance with the requirements of the
executive project.

3.5

Maximum time settings. Normative restrictions

During programming via the Previdia/STUDIO software you can set the time length or delay of many control panel
functions. The normative reference standards require maximum duration for the following parameters:

•

Prealarm time

, the maximum delay time is 10min (EN 54-2 - clause 7.11.1 (c)).

•

Verification time OFF (s)

, if the verification function is enabled for an input device, the time for which the device

remains deactivated after the first activation must be 60 seconds maximum (EN 54-2 - clause 7.12.1 [b]).

•

Verification time (s)

, if an input device has the alarm verification option enabled, the maximum verification time is 30

minutes (EN 54-2 - clause 7.12.1 [c]).
