Basic Operation and Supervision
Basic Operation and Supervision
The DTC-300A 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 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 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 to seize the line and try reporting again. For two regular Telco telephone line connections, the DTC-
300A checks each line operation by reporting the 24 hour periodic test result on Line #1 or Line #2 alternately.
The DTC-300A 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.
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.
