Charging Circuit
The D2071A charges the battery with a float charge
circuit using a maximum charging current of 300 mA.

Telephone Cord Installation
Use a D161 or D162 Phone Cord to connect the primary
telephone line to the D2071A Modular Jack ( J1). Use a
second D161 or D162 Phone Cord to connect the
alternate telephone line to the D2071A Modular Jack

For all applications, you must connect
separate primary and alternate telephone
lines to the D2071A.

2.8.3
Telephone Line Supervision
The D2071A monitors both the primary and alternate
telephone lines while the communicator is idle by
sniffing the line for trouble. Telephone line trouble is
line voltage below 10 VDC with a current less than
10 mA. If there is a report waiting to be transmitted, the
D2071A does not sniff the telephone lines until the
report is transmitted or a communication failure occurs.
The D2071A reports a faulted condition on the primary
telephone line as a TROUBLE ZN B and the alternate
telephone line as a TROUBLE ZONE C.

The D2071A reports a faulted condition on the primary
telephone line as a TROUBLE ZN B and the alternate
telephone line as a TROUBLE ZONE C.
Each line is sniffed once a minute if both lines are good.
If a line is determined to be in trouble, the D2071A
steps up the test rate and sniffs once every 10 sec. If the
trouble still exists after 15 samples (150 sec), the control
panel sends a Trouble Report and activates the buzzer,
Phone Fail LED, and Phone Line Trouble Relay (if
installed). Ref
