5.3 System Operation
5.3.1 Modes of System Operation
There are three modes of system operation for the D7024 control/communicator:
• Normal Operation: When the system is operating normally, it displays “SYSTEM NORMAL” on the top line of the
display, the Power LED is on steady, and no other LEDs are lit. If the system is programmed to
require a PIN, the second line of the LCD screen will display “ENTER PIN:”, otherwise the control
panel will bypass this display and will show a rotating menu of possible user actions.
• Alarm Operation: When an alarm occurs, the top line of the display will show “FIRE ALARM”. This display will override
any other system display. The second line of the display will show the number of the point that is in
alarm, alternating with the programmed description for the affected point. If more than one alarm (or
other off-normal condition) is active, they will be shown on the second line of the display, one after
another. The built-in sounder turns on with a steady tone, and outputs programmed to activate with
the current alarm condition(s) will activate.
• Trouble Operation: When a trouble condition occurs (e.g. wiring for a point is cut, AC power fails, etc.), the sounder will
activate briefly, every 10 seconds. The Trouble LED will light and the top line of the display will
show “SYSTEM TROUBLE”. The second line of the display will identify the specific problem.
5.3.2 Point/Zone Mapping
The panel supports a system to map the input points to output points.
Input points are assigned, during installation, to a zone. Each input point can be assigned to only one zone; however,
multiple input points can be assigned to the same zone. Output points are also assigned; however, they can be as-
signed to up to four different zones. This allows an alarm condition on an input device assigned to zone one to cause all of
the output devices assigned to zone one to activate.
Assign input points to zones in [PROG/0] [4-PROG INPUTS] [3-ZONE ASSIGN]. Remember, each input point can only
be assigned to one zone; however, a zone can have multiple input points assigned to it. In our graphic, above, there are
7 smoke detectors assigned to each zone. Output points (NACs) are assigned in [PROG/0] [5-PROG OUTPUTS] [3-
ZONE ASSIGNS]. Here, individual output points can be assigned to up to four zones. This allows a smoke detector on the
first floor of a building (assigned to zone 1) to cause horns (also assigned to zone 1) to sound on floors 1 and 2.
Up to 64 zones can be assigned. Zones 1 to 50 can be assigned by the installer. Zones 51 to 63 are preassigned to
system conditions.
Preassigned Zones:
• Zone 63: General Alarm - active while any alarm, including supervisory, is present; remains active even while system
is silenced.
• Zone 62: General Trouble - active while any system trouble is present.
• Zone 61: General Waterflow - active while any waterflow alarm is present.
