To connect a remote alarm indicator, use a male DB-15 connector to attach a 15-lead
cable to the ALARM RELAY connector of the Stinger MRT unit. Then attach wire
from the pins of the DB-15 connector to the remote indicator according to Table 3-1.

unit, see the Stinger Administration Guide.

Connecting a Stinger MRT to monitor the alarm status of other devices

The connection to each external device consists of a pair of 24-to-28-gauge wires.
One wire supplies ground, and the other monitors the alarm status of the remote
device by applying 3.3Vdc, which draws less than 10mA of current through the
closed contacts of the alarm relay on the remote device. For a complete listing of the
pinout arrangement of all alarm connectors on the DB-15 connector, see "Alarm
connector pinouts" on page C-2.
To monitor a remote device, use a male DB-15 connector to attach a 15-lead cable to
the ALARM RELAY connector of a Stinger MRT unit. Then attach wire from the pins
of the DB-15 connector to the remote devices that will be monitored, according to
Table 3-2.
