Technical / Programming Manual
FT128 Rev 2.2
118
14.15.10 Disconnect / Re-connect addressable zone interface input
A zone interface input (e.g. 2821/3361) can be disconnected via menu H8/S3.
Disconnected zone interface input will stay disconnected until Re-connected via menu
H8/S3.
14.15.11 Disable Interlocking Output
The control outputs of type "Interlocking output" can be disabled via menu H9/C4, Disabled
outputs will stay in (or return to) the normal condition for the output respectively
until Re-enable via menu H9/C5.
14.16 Test Mode
Alarm points / zones can be tested during the monthly / annual test via menu H1 or H7. Up
to 99 zones can be set in Test mode via menu H7 at the same time but only four zones via
menu H1. For more information see the FT128 Operation Manual. The LED "Test mode"
on the CIE front indicates one or more zones in Test mode. Zones in Test mode are also
simultaneously shown in the FT128 display
. In order to shorten the testing time, any time
delay for the detectors / zones in test mode will be "shortened", i.e. fire alarm will be
activated faster than normal.
14.17 Test Alarm Devices
The programmable outputs type "Alarm device" can be collectively activated via menu
H8/S6, which make it possible to test the alarm devices (the test cannot be started if a fire
alarm is already activated). When the test starts the alarm devices will be turned "ON" for
5 seconds (±1s), "off" for 25 seconds (±1s), "on" for 5 seconds and so on.
Note: Disabled (and silenced) alarm devices will also be tested.
The test will continue for one hour if it is not stopped via menu H8/S6 or if a fire alarm is
activated in the system.
14.18 Test of Routing Equipment
Via menu H1 it is possible to test the fault and fire alarm outputs for routing equipment
(Fault TX & Fire brigade TX).
In menu H1, press "Accept" to start the test. The fault output will be activated
, indicated
by LED "Fault TX activated". After 30 seconds will also the fire output be activated,
indicated by LED "Fire brigade TX". After additional 30 seconds the test will be terminated
and the outputs and LEDs will go back to "normal" status.
Note: In the Australian and New Zealand conventions, testing of the routing equipment is
conducted via the ASE.
14.19 Calibration of Supervised Outputs
The supervised (monitored) voltage outputs must be calibrated during commissioning of
FT128 system. This is done via menu H5/A1. A value outside the calibration range 4K7Ω-
50KΩ and 470 nF to 5x470 nF will generate a fault as well as an actual value that differs
from the calibrated value ± a small tolerance.
Disablements, faults and fire alarms have higher priority, i.e. the presentation of zones in Test mode will be suppressed during
such a condition.
Any 2-zone / -address dependence and the function "delayed alarm" will be ignored.
The output activation will be continuously (steady). For the alarm devices 4477 and 3379, the tone with the highest priority
level (and type "alarm device") will be automatically selected.
NOTE! The Fault TX output is activated in "normal" state, i.e. it will in this test be de-activated.
