2.4.6. The Water Alarm

Description
The purpose of the Water Alarm is an alarm system consisting of water sensors integrated as Passive or
Active detector. The wiring makes it possible to replace conventional fire alarm systems.
Water detectors are generally included in the system through the objects "Passive detector" or "Active detec-
tor". The alarm system is automatically alert after elapse of the Reset delay (set with the reset object), when
the Configuration software has been downloaded or the Master Generator has been switched on. The Reset
output switches on within this time.
An alarm is triggered off when one or several alarm contacts are activated for more than 10 s. The system
steps through the activated alarm contacts (as alarm indication) as well as the alarm output approx. every
second. The alarm siren flashes with a pulse-pause ratio of approx. 3 s/57 s. By subsequent activation of the
reset key, the Master Generator resets the stepping through of the alarm contacts and the alarm output. If
contacts are still activated, another alarm is triggered off after elapse of the reset delay.
Note: Configuration of the object "Reset" is absolutely necessary to ensure correct function.
The status of the alarm contacts can be shown in a simple way on a panel. All that is needed for this purpose
is that the output channels are coded to the addresses of the alarm contacts.
The object "Alarm signal" makes it possible to control a telephone or GSM modem because of the short mes-
sage on this channel.
For alarm purposes, the object Common Siren can also be used. Details can be found in the chapter describ-
ing the alarm siren/Common siren.
The various fire alarm objects are selected under "Channel function":
Passive detector:
Active detector:
Reset:
Alarm siren:

• Function: Water alarm system including Passive detector, Active detector, Reset, Siren and
Alarm signal
• Application: Wiring of water indicators, eg the water stop sensor, to an alarm system
• Select with mouse ("Water alarm") or short-cut key "W"
Normally
passive detectors. When the contact is activated and a "1"-Signal
consequently transmitted on the Dupline bus, an alarm is started.
Normally
active detectors. When the contact is activated and a "0"-Signal
consequently transmitted on the Dupline bus, an alarm is started.
This object makes it possible to include a button to reset the alarm and restart the
system.
If a contact is activated during reset, a new alarm is started after elapse of the
Reset delay.
Note: This object must be configured in order to achieve correct function of
the water alarm system.
The alarm siren indicates the occurrence of an alarm. The channel configured

modules. It usually activates a relay output switching a siren.
In case of alarm, this output flashes with an on-time of approx. 3 s and an off-
time of approx. 57 s.
When an alarm occurs, a channel configured for this object is activated for 10
s and can thus be used to activate a telephone or GSM modem.
