Calibration of supervised outputs

The supervised (monitored) voltage outputs have to be calibrated after
the installation is finished. This is done in EBL128 via menu H5/A3.
A value outside the calibration value range 4K7-50K and 470 nF to
5x470 nF respectively, will generate a fault as well as when the actual
value differs from the calibrated value ± a small tolerance.

Service signal

A smoke detector becomes contaminated no matter what environment
it is mounted in. In some environments it goes faster than in others.
Conventional smoke detector: The sensitivity will normally increase
in most environments.
(nuisance alarms) since all conventional smoke detectors (except
4350, see page 116) have a fixed fire alarm level. Conventional
smoke detectors have no service signal output.
Analog smoke detector:
109
constant up to a fixed service level when Service signal will be
activated. Service signal will be generated for 4300 / 4301 (in
NORMAL mode) when the week average sensor value is > 1.8 %/m.
See also the EBL128 Operating Instructions chapter "Sensors
activating SERVICE signal (H4/U4)" and "Acknowledge SERVICE
signal (H8/S1)".

Fault signal (fault condition)

Fault signal, fault messages, fault acknowledge, etc. are described in
EBL128 Operating Instructions, chapter "Fault".
Programmable inputs can be used to activate fault signal in EBL128,
see chapter "Programmable inputs", page 54.

Alarm texts

The alarm texts are shown in case of a fire alarm.
The display in EBL128:
presentation number for an alarm point and on the second row will
be shown a user definable alarm text for this alarm point, if
programmed via Win128.
An example of fire alarm information:
ZONE-ADDR 12-45 █ LAST ZONE 12 █ No.01
User definable alarm text for 12-45
109
The detector is supervised at all times and adapts its fire alarm level in
relation to the contamination of the detector, see chapter "Analog smoke
detectors", page 81.
