User number 00 is designated as a Master Code. It can
be used to silence alarms, reset, disable, and program
the D7024. This number is shipped from the factory
with the default sequence of 9876. When you change the
default sequence to a number of your personal
preference, you are automatically assigned maximum
authority.
Authority levels are assigned to PINs to determine
which functions each user can perform.
Table 15
describes the four authority levels.

Communicator Operation
The D7024 contains an integrated communicator that
can be enabled to send reports to a monitoring station.
When enabled, communicator operation fully
automatic.
To disable a telephone number, set FORMAT to
0 = Disable. To completely disable the communicator,
set FORMAT to 0 = Disable for both telephone
numbers, and set MONITOR to 0 = NO for both
telephone lines.
When events occur, the communicator sends them to
the monitoring station in priority order according to
NFPA requirements. Fire and waterflow alarms are sent
first, supervisory alarms and trouble reports are sent
next, and all other reports are sent last.
Priority reporting can send a Restoral Report after
several Alarm Reports in a situation where a point sends
multiple alarms, indicating a point is restored when it
returned to alarm. The sequence “alarm”, “restore”,
“alarm” is transmitted as alarmed “restore” when
priority sorting is applied.
The communicator can store 32 events while waiting for
the monitoring station to accept the events. If more than
32 reportable events occur before the monitoring station
accepts events, some event information is lost and a
Data Lost Report is sent to the central station.
The D7024's communicator is equipped with a line
seizure relay to prevent interference with outgoing event
reports. In a system where the fire communicator shares
the telephone line with other equipment on the
premises, the telephone line might be unavailable to the
other equipment for up to 15 min if there is a fault with
the central station acceptance of the event data.
Telephone lines for FACPs must not be shared with
other equipment.
Never program PINs with common
sequences such as 1111, 1234, or 2468
because they are easily violated.

PIN Authority Level
Authority Level
Allowed Operations

All control panel operations, including
programming
Medium (2)
System test modes, fire drill, reset, dis-
able, silence, view history.
Minimum (3)
Silence, view history.
None (0)
None.
The communicator must be enabled and con-
figured before it will work. The communicator
and telephone line monitors are disabled in
the default factory configuration.
Do not install the D7024 FACP on a tele-
phone line that might be needed for other
emergency use.
Priority sorting on events sent to a monitoring
station can cause the message sequence to
indicate a point is restored when it is not.
