3. Alarm Verification Feature
When this is set any detector that enters a fire condition will show on the panel but no sounder
program will be activated, a 15 sec timer will start. At the end of the 15 sec, if the detector is still at
alarm level the sounders will activate. If during this time the detector has dropped below the alarm
level then the panel will not go to alarm.
This is particularly useful to prevent false alarms from detectors where the smoke is from other
sources other than a fire i.e. smoking in bedrooms.
On later version software the AVF length can be timed from standard or long delay (30 secs) and
when in UL 864 9
th
edition mode a longer time (60 secs) has also been added. (see page 27)
A further option includes the addition of AVF on specific zones.
4. Auxiliary Board
Extra boards or additional features for other markets can be installed within the DF6000. These
include Extinguisher and Fire brigade boards to enable the control of other services within buildings in
Germany.
Australian Mode creates a re-configured display screen when class change is shorted. In this mode a
key-switch device is installed on the front door of the DF6000 panel which can only be operated by
the Australian fire brigade (this key-switch shorts the class change). Address or zone text for the
alarm can be viewed on the screen depending on how the screen is configured. (See page 21)
The re-configured screen gives the Fireman controls to; silence the alarms, mute buzzer and reset the
panel without having access to the pass-code.
Swedish mode is very similar except that the panel must be in Swedish language for this feature to be
operational.
5. HMO Mode
This feature has been added to accommodate BS 5839 Part 6
– Fire Alarm Installations in Dwellings.
BS 5839 part 1 does not cover private dwellings, however, a landlord is required under this to protect
all common areas within his building, and generally this would be designed as L3 coverage with a
detector and sounder in the lobby area of the flat.
Mains smoke detection would then be installed within the living accommodation to provide protection,
but preventing a false alarm in a flat evacuating the whole building.
This system is set up using the menus on the panel and the Site installer program.
Each sounder within a flat should be programmed to go continuous by the HMO zone or device
addresses in the flats up to a maximum of 16.
The adjacent zones can then be programmed to go pulsing after a delay which will be the same as
the reset timeout explained below.
There are 3 settings within the HMO menu;
1. Class Change;
this is the controller of HMO mode, when class change is set to
‘global alarm’
the mode is on. In this instance, if there are any pulsing sounders adjacent to the zone in fire,
then operation of class change will change them to continuous. Setting class change back to
‘normal operation’ on the screen HMO will be turned off.
2. HMO Zones;
This button allows the operator to select the zones required to be in HMO
mode.
