Test of outputs
The programmable outputs (including addressable alarm devices) can be tested i.e.
activated via EBLWin but also via menu H8/S8. At the start of the test, the output will be
activated even if its control expression is false. At the end of the test, the output will be de-
activated but only if its control expression at that time is false.
17.21
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 and corresponding programmable outputs). Open door etc. will
not affect the test.
In menu H1, select "Yes" and press "
" to start the test. A 60 seconds count-down starts.
The "Fault condition" output will be activated
135
, indicated by LED "Fault TX activated" on
the CIE front. After 30 seconds, the "Fire alarm" output(s) will also be activated, indicated
by LED "Fire brigade TX" on the CIE front. 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.
17.22
Calibration of supervised outputs
The supervised (monitored) voltage outputs must be calibrated during commissioning of
FT1020G3 system.
136
This is done via menu H5/A1 in the CIE
Calibration range is
4K7
– 50K
or
470 nF
– 5 x 470 nF
.
A value outside the calibration
range 4K7-50K 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.
17.23
Service signal
A smoke detector becomes contaminated no matter what environment it is mounted in. In
a harsh environment, contamination is accelerated.
Conventional smoke detector: The sensitivity will normally increase in most environments.
This can result in nuisance alarms since conventional smoke detectors have a fixed fire
alarm level. Conventional smoke detectors have no service signal output and have to be
replaced on a regular basis (i.e. before being fully contaminated).
Analogue smoke detector: The sensitivity will automatically be constant.
137
Service signal
will be activated at a
fixed
service level
. Service signal will be generated for detectors
4300, 4301, 4400 and 4401 in NORMAL mode when the week average sensor value is >
1.8 %/m.
For detectors 4400 and 4401 in Advanced mode, the Service signal will be
activated when the sensitivity compensation value is 2 %/m.
One or more detectors having activated SERVICE signal is indicated by the LED "Service"
on the CIE front. A programmable output can also be activated.
When a "dirty" detector has been replaced by a new/clean one, its week average sensor
value has to be set to default. This is done via menu H8/S3.
135
Note:
Fault condition outputs are normally activated in "normal" state, i.e. they will in this case be de-activated.
136
CIE outputs S0-S3: EOL resistor 33K. 1
– 5 resistors (33K) can be used. 3364 outputs VO0-VO1: EOL capacitor 470 nF. 1
– 5 capacitors (470 nF) can be used.
137
The detector is supervised at all times and adapts its fire alarm level in relation to the contamination of the detector, see
chapter "", page 102.
