The DVA-TNT is designed to be wall mounted and should be placed near a source of A/C power. The temperature sensor
is only installed if the announcement is to include temperature information.

Incoming C.O.

(for local programming)
After the DVA-TNT is mounted, the incoming phone line may be connected. An RJ11 jack is provided for modular con-
nections, as well as a two-position terminal block for stripped wire.
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.
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.
D. Battery Backup
The DVA-TNT features a rechargeable battery backup. When the rest of the installation has been completed, battery
backup of the unit should be activated by moving the battery backup shunt from OFF to ON (see diagram above).

A. Accessing Programming
Programming can be completed either locally with a Touch Tone phone connected to the "Program Phone" port, or by
calling into the "Line Input" jack from a remote location.
1. Local Programming
a. Attach the PROGRAM PORT jack to a phone or unused trunk port (see diagram above).
b. Go off-hook on the phone or trunk port connected to the "Program Phone" port.
c. If the DVA-TNT is in the ring-trip mode, two beeps will be heard indicating that the unit has entered program-
ming. If the DVA-TNT is in the drum recorder mode, it will complete its current message cycle and then give
two beeps to indicate it has entered programming.
