u 12 VDC or 24 VDC operation

u Supports multiple reporting formats

The D9068 Fire Communicator is a complete digital
alarm communicator transmitter (DACT) for use with
compatible fire alarm control panels (FACPs). Use dry
contacts or open collector outputs for alarms and
communications with the D9068.

Functions

Five Input Points

The DACT supports five inputs that can be activated by
dry contact relays or open collector outputs. Each of
these inputs can be configured for one of seven types
of conditions: Fire Alarm, Waterflow Alarm,
Supervisory, Monitor Alarm, System Fault, AC Failure
and Low Battery.

System Supervision

The DACT is supervised with a hardware watchdog
circuit. Failure of the control program results in a
hardware reset within two seconds. The on‑board
trouble relay releases for the duration of the reset (the
relay is normally held energized).

u Five user-programmable input points (Class B,

Style B)

u 100-event history buffer

u Dual phone line interface

The DACT's EEPROM memory, input points, and phone
lines are automatically tested periodically. The
EEPROM checksum is verified every 10 minutes. If the
EEPROM checksum fails, a trouble condition is locally
annunciated and a trouble report sent.

Serial Data Input Dialing

The DACT connects through the D9052 Serial Module
to the D10024, D10024A, D9024, and D8024 analog
FACPs, and transmits by point in all available formats.

User Interface

An FMR‑DACT‑KEYPAD LCD Keypad connects to a five­pin connector (option bus interface) and is used to
program and troubleshoot the D9068. A D7033 Liquid­Crystal Display (LCD) Remote Keypad can also be
used.

Reporting Formats

The DACT supports five reporting formats: Modem
IIIa2, Contact ID, SIA110, SIA300, and 4/2.

Report Routing

There are six different report groups that can be
routed to one of four phone settings. These report
groups consist of non-supervisory alarms, supervisory
alarms, alarm restorals, resets, supervisory restorals,
tests and troubles, and trouble restorals.

Reset Report

A reset report is sent when the D9068 resets from any
off-normal condition.

Phone Line Selection

The DACT follows a pre‑determined sequence to select
between the phone lines. It also implements the new
NFPA requirements for alternation of phone lines
during test reporting. The DACT maintains a variable
that selects either Phone Line 1 or Phone Line 2 for
automatic test reports. After each successful test
report, the variable switches to select the other phone
line.

Communication Failed Indication

The DACT indicates a communication failure after ten
attempts to communicate are completed without
success. This causes the trouble output to activate
and report the fault.

History Buffer

The DACT has a history buffer that retains up to 100
events. Each event is tagged with the date and time of
occurrence. This buffer can be viewed when an
FMR‑DACT‑KEYPAD LCD Keypad (or a D7033 LCD
Remote Keypad) is connected to the D9068. When the
buffer is full, old events are discarded to make room
for new events.

Lightning Suppression

MOVs and spark gaps suppress lightning surges and
static discharges for inputs and telephone interface.
