Disablements
It is possible to disable parts of the system. This may be required if there are works going on in a building
which may cause the fire alarm system to operate in error.
16.12
Disable zones
To disable zones, the
Enable Control
keyswitch should be activated and the
Mode
button pressed until “d”
appears in the first of the two seven-segment LED displays. The
Select
button should then be pressed to
select the number of the zone which is to be disabled in the second of the two seven-segment displays.
Once the desired zone is displayed, the
Enter
button should be pressed to confirm the disablement.
The
Disable
LED will light and the
Zone Fault
LED will light for each disabled zone.
16.13
Disable sounders
To disable sounder outputs, press the
Mode
button to select “db” on the seven-segment display. Pressing
Enter
will disable all sounders and cause the
Disable
and
Sounder Fault
LEDs to light.
16.14
Activate delays
To activate delays on zones as set in configuration options 31 to 48, press the
Mode
button until “Ad’
appears on the seven-segment LED display. When the
Enter
button is pressed any zones that are set as
delayed will have their alarm outputs delayed by the time set in configuration options 00 to 09.
16.15
Disable fault contact
The fault relay can be disabled by selecting configuration option 22.
16.16
Test mode
Fire alarm systems must be tested regularly to ensure that they are functioning correctly. The Sigma CP
range of panels enable the system to be tested single handed by using a test mode. When in test mode,
activation of a fire alarm will be automatically reset after a few seconds to eliminate the need to return to
the control panel to reset after every activation.
Test mode is entered in a similar way to disablements. With the
Enable Control
keyswitch activated, press
the
Mode
button until “t” appears in the first of the seven-segment displays. Then press the
Select
button
until the required zone number appears. Pressing the
Enter
button will cause the
Test
and
Zone Fault
LEDs
to illuminate indicating the zones which are in test mode.
Disablements and zone tests are cleared by repeating the sequence that is used to select them, i.e. the "db"
function (for example) toggles between sounders disabled and sounders enabled.

Configuration options
The Sigma CP range of control panels has many configuration options which can be set at the time of
commissioning to suit the requirements of the installation. These options are normally set once and will
rarely need to change. The configuration options are only available at access level 3. To access level 3,
CAREFULLY slide the
Write Enable
switch (located behind the aperture in the panel plate) to the right
position using a small screwdriver or similar. When the panel is at access level 3, the buzzer will “pip” three
times every few seconds as an indication that it is at this access level.
