iRIS8 - Addressable Fire Alarm Panel
– Installer Programming
15
Examples for DOUBLE operation mode:
1
– An incoming alarm signal from Detector 1 and zone reset;
2
– Waiting for a second alarm signal from the same detector in the zone – Pre Alarm Mode;
3
– Second alarm signal from Detector 1 in the zone.
EXAMPLES 1, 3: In this case the fire panel will not activate the sounders and the signalization on the front panel
because during time interval (2) no second alarm signal is generated.
EXAMPLES 2, 4: In this case the fire panel will activate the sounders and the signalization on the front panel because
during time interval (2), two alarm signals are generated.
3.1.3. Setting Time Delay T2 for Zone
For every zone number is set a specific time delay Т2 for activation of the panel’s outputs. The time delay is set in
inte
rval from 0 to 540 seconds, as setting “0” means that there will be no time delay for activation. A T2 delay of 60
seconds is set by default for Sounder and Fire Brigade outputs. If no delay (T2=0) is set for an output - Sounder, Fire
Brigade or Fire Protection, the introduced common delay T1 is also ignored for activation from that zone. See the item
for setting the T1 common delay.
For example, if the “Sounder Delay (T2)” = 0 for Zone 1, then the set T1 time delay will be ignored and the output will be
activated immediately in case of Fire alarm event for that zone.
- Two steps of alarming algorithm.
In case of activation of more than one zone, the delays to the outputs are caused by the zone with shorter
delays.
3.1.4. Programming of Sounder Groups
The arranging of all sounders attached to a single zone in a common Sounder Group is an option that helps for better
management of the evacuation process at the protected site in case of fire alarm condition. To every zone number
can be attached up to 3 other Sounder Groups (which belong to other zones). In case of fire alarm condition, will
be activated not only the sounders in the respective zone but also and the sounders in the associated to it Sounder
Groups (A, B, C). The installer can organize up to 127 separate Sounder Groups in a fire alarm system build with iRIS8
panel. It is recommended to arrange the Sounder Groups according the respective zone numbers in advance.
To set additional Sounder Groups to a zone number, press MORE button.
In the second settings screen of the zone menu, the installer sets the operation of the sounders associated to the
respective zone number. The zone number is associated in the individual programming menu of every device
– see
The operation of Zone Sounders depends on the selected setting - Enabled or Disabled:
•
When the ZONE SOUNDERS are ENABLED
, in case of fire alarm event in the respective zone, the sounders
in the set Sounder Groups (A, B, C) will be activated together with the sounders associated to that same zone.
•
When the ZONE SOUNDERS are DISABLED
, in case of fire alarm event in the respective zone, ONLY the
sounders in the set Sounder Groups (A, B, C) will be activated and the zonal sounders will not be activated (the
sounders associated to that same zone).
Note: The zonal sounders will be activated (in Zonal Mode Disabled) if
they are included to a Sounder Group set for the respective zone.
When ZONE SOUNDERS DISABLED and a “0” is set for all of the Sounder Groups, then there will be no sound
signalization in case of fire alarm from the respective zone.
For every sounder group is set a number from 1 to 127 according the system configuration.
Example: Offices A and B are sharing a common corridor in a floor plan of a building. All attached sounders to the
Zones are arranged into separate Sounder Group numbers. In case of a fire alarm condition in Zone 1, the sounders in
Zone 2 and 3 will be also activated, when the Zone Sounders option is ENABLED and the two other Sounder Groups
numbers are set in the Sounder Group fields for Zone 1. The same is organized for Zones 2 and 3.
