1. DESCRIPTION
The UD-2000 Digital Alarm Communicator Transmitter (DACT) provides for up to two (2) phone lines for communication
to a monitoring station. The UD-2000 DACT communicates using the SIA-DCS or Ademco Contact ID protocols. When
enabled, the DACT automatically monitors each phone line or voltage and has the ability to seize the line and connect
with a remote receiver. Once the communication is complete, the DACT will hang up the phone line.
The DACT is provided with terminal blocks for each phone line. In order for the DACT to work properly, it must be installed
on a plain old telephone service (POTS) or equivalent as deemed by the authority having jurisdiction. The DACT must be
installed before any other equipment to ensure it can seize the line and disconnect any other lines.
Phone lines are high voltage and should be run in a separate conduit from other circuits. The wire conductors connecting
the DACT to the phone system should be 26 AWG or larger.
When the phone lines are connected to the control panel, the phone lines are supervised. The phone line are non-power
limited and should be routed accordingly.
UD-2000 comes factory addressed as address 1
To comply with UL 864 10th Edition, an alternate source of communication shall be used as the secondary means of
communications and shall not be a phone line.
