DTC-300A-2 Dialer Installation and Operation Instructions

Power Up Procedures
1. The DTC-300A-2 should be securely mounted on a wall. Make sure ground wire is connected.
2. Check that the telephone lines are connected as shown in Figure 4 or 9.
3. Connect the optional CFG-300 Configuration Tool to the U18 connector and place over the mounting studs on
the DTC-300A-2 above the key pad and secure. This CFG-300 Configuration Tool can be removed once
configuration has been completed.
4. Power up the Fire Alarm Panel and the message on the CFG-300 Configuration Tool should be:
Basic Operation and Supervision
The DTC-300A-2 is able to supervise up to 6 local configurable input zones. Once the input zone is active (short
condition), the corresponding event with input zone number will be reported to the monitoring station. If the input
zone is open, a corresponding circuit trouble with input zone number will be reported. Each input zone can be
defined as Alarm, Supervisory, Trouble, Waterflow, AC Power Trouble or Battery Trouble.
The DTC-300A-2 is capable of reporting multiple events to a single account number, within a single call session.
For a single event not yet reported, up to 4 retries will be made within a single call attempt. A failure to report to
either or both accounts will generate corresponding events that will be queued for reporting. Once the DTC-300A-2
fails to report on all telephone lines, it stops retrying, but an Alarm Event, Manual Test or 24 hour Periodic Test will
force the DTC-300A-2 to seize the line and try reporting again. For two regular Telco telephone line connections,
the DTC-300A-2 checks each line operation by reporting the 24 hour periodic test result on Line #1 or Line #2
alternately. For a cellular line 2, selection of the Auto Test time between 12:01 and 23:59, allows the DTC-300A-2 to
check each line every 12 hours, alternately.
The DTC-300A-2
continuously supervises the state of each of two connected Telco Lines at approximately 1 minute
intervals.The regular line supervision includes DC voltage level validation and dial tone detection. Line supervision
is skipped while (1) the dialer is busy reporting, (2) the modem is working or (3) there is ringing on the line. If the
line supervision fails, a Line #1 or Line #2 Trouble will be reported after a 30 second verification. Once the line has
been restored, a Line Trouble Restore will be reported.
Configuration Set-up
There are 3 ways of configuring the DTC-300A-2.
1. Locally with the on-board keypad and CFG-300 Configuration Tool.
2. Locally with a Personal Computer via the RS-232 connection, a UIMA and Mircom Software MSW-012.
3. Remotely with a computer, modem, UIMA and Mircom Software MSW-012.
CONFIGURATION VIA ON-BOARD KEYPAD
1. Connect 24V DC power supply and zone inputs from the DTC-300A-2 to the fire alarm panel.
2. Hook up the CFG-300 Configuration Tool ribbon cable to U18 on the DTC-300A-2 board.
3. Hook up the telephone lines and telephone as shown in Figure 4.
