Planning Instructions Fire alarm system EBL512 G3, United version 2.7.x
106
Conventional smoke detector: The sensitivity will normally increase
in most environments. This can result in unwanted false alarms
(nuisance alarms) since all conventional smoke detectors (except
4350, see page 124) 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 too contaminated).
Analog smoke detector: The sensitivity will automatically be
constant.
102
Service signal
will be activated at a fixed
service level
.
For detectors 4300 and 4301 (in NORMAL mode), Service signal will
be activated when the week average sensor value is > 1.8 %/m.
For more information, see EBL512 G3 version 2.7.x Operating
Instructions MEW01473 chapter "Sensors activating Service signal
(H4/U5)" and "Acknowledge Service signal (H8/S3)".
16.26
Fault signal (fault condition)
Fault signal, fault messages, fault acknowledge, etc. are described in
EBL512 G3 version 2.7.x Operating Instructions MEW01473, chapter
"Fault".
Programmable inputs can be used to activate fault signal in the
EBL512 G3 c.i.e. (United version 2.7.x). See chapter "Programmable
inputs", page 60.
16.27
Alarm texts
The alarm texts are shown in case of fire alarm.
When a fire alarm is activated, the presentation number (Zone –
Address) will be shown in a field in the middle of the c.i.e. display.
On the row just below the presentation number, the user definable
alarm text for that alarm point will be shown, if programmed.
103
The
alarm text will also be presented in Ext. Fire Brigade Panels, etc. The
alarm text will be printed when a printer is available in the c.i.e or the
Ext. FBP.
See also EBL512 G3 version 2.7.x Operating Instructions
MEW01473, chapter "Fire alarm".
The alarm texts, up to 40 alphanumeric characters, are created and
downloaded via Win512 version 2.7.x. Each addressable alarm point
can have the same alarm text displayed in the Ext. FBPs 1826 & 1828,
the Alert Annunciation units 1735 & 1736 and in the Ext. Presentation
unit 1728 or a different alarm text in each unit.
102
The detector is supervised at all times and adapts its fire alarm level in
relation to the contamination of the detector, see chapter "Week average
sensor value", page 84.
