A. Ring Trip Interface
Connect a phone line or analog PABX/KSU station to the LINE INPUT jack or teminals.
B. Drum Recorder Interface
The DVA-TNT provides an E-lead dry contact closure across pins 1 and 2 which can be programmed as N/O or N/C.
Connect terminals 1 and 2 (E-lead) to the busy lead terminals of the phone system, and terminals 3 and 4 (600 ohm
audio output) to the 600 ohm terminals.
A. Accessing Programming
C. Temperature Sensor
The temperature sensor should be attached using the supplied mounting bracket on a secure surface, in an area where
the temperature is to be monitored. If the sensor is located outdoors, it should be mounted in an area that is shaded
and will not be submerged in water or covered by snow. If using additional wire is required, indoor/outdoor CAT2 or
better is recommended. The maximum wire run from the DVA-TNT to the sensor is 1500 feet.
