1.1 System
Overview
The D9068P Fire Communicator is a complete communicator for use with AX Series Intelligent Fire Alarm Control
Panels. Alarms and communications to the D9068P are accomplished via serial connection. The D9068P includes:
Multiple data protocols (Contact ID, and SIA 300)
100-event history buffer
Dual telephone line interface
Connections for programming LCD Keypad (DACT-PRG)
LEDs for heartbeat, DACT trouble, and telephone line trouble (one per line)
Serial port for connection to the AX Series Intelligent Fire Alarm Control Panel
Real-time
clock
1.2 Features and Specifications
1.2.1 Power
Table 1: Power Specifications
Input Voltage
10.2 to 28 VDC
Standby Current
150 mA
Alarm Current
190 mA
Power for the D9068P is wired directly to the
AX Series Intelligent Fire Alarm Control Panel via the AX-SEB cable
.
Although the D9068P can withstand short power losses up to 5 minutes, power losses (AC & DC) greater than 5
minutes, could possibly cause the following:
History buffer might clear and all stored events are lost.
Output (report) buffer might clear and all pending reports are lost.
Alarms initiated before the power loss might reset. If the alarm conditions persist when power is restored,
new alarms will be generated.
DACT time might reset to its default setting.
1.2.2 System
Supervision
Watchdog:
The D9068P is supervised with a hardware watchdog circuit. Failure of the control program causes a
hardware reset within 2 sec. The AX Series Intelligent Fire Alarm Control Panel will indicate a DACT trouble
condition under this situation.
Self Testing:
Occasionally, the dialer (DACT), EEPROM memory, and telephone lines are automatically tested.
The EEPROM checksum is verified every 10 minutes. If the EEPROM checksum fails, a DACT trouble condition is
indicated on the AX Series Intelligent Fire Alarm Control Panel and a Trouble Report is sent to the Central Station.
1.2.3 Trouble
Contact
The D9068P has one Form C relay rated 1 Amp @ 30 VDC. The Form C relay is normally held active and
deactivates on any DACT trouble condition.
Note: The trouble contact is not utilized when utilizing the D9068P in conjunction with an AX Series Intelligent Fire
Alarm Control Panel. All DACT trouble conditions are reported to the FACP via the supervised serial connection.
If a power loss occurs, programmed settings such as point configuration, telephone numbers, and account
number remain intact.
