Digital Communicator
Two modular phone jacks allow easy connection to telephone lines. Modular jacks are labeled PH1 and
PH2 for the Primary and Secondary phone lines. Telephone line 'Primary and Secondary Active' red
LEDs are provided as well as a green 'Kissoff' LED. The integral digital communicator provides the
following functions:
• Line Seizure - takes control of the phone lines disconnecting any premises phones.
• Off/On Hook - perform on and off-hook status to the phone lines.
• Listen for dial tone - 440 hertz tone typical in most networks.
• Dialing the Central Station(s) number - default is Touch-Tone®, programmable to rotary.
• For tone burst or touchtone type formats: Discern proper 'Ack' and 'Kiss-off' tone(s) - The
frequency and time duration of the tone(s) varies with the transmission format. The UDACT will
adjust accordingly.
• Communicate in the following formats (refer to "Compatible Receivers" on page 65 for
compatible receivers):
6 Tone Burst Types: 20 pps (3+1, 4+1, 4+2)
3 Touchtone Types: 4 + 1 Ademco Express, 4 + 2 Ademco Express and Ademco Contact ID
The UDACT circuit board contains a CPU, other primary components and wiring interface connectors.
Circuits
Communications
Communications between the UDACT and the host control panel is accomplished over a two wire
EIA-485 serial interface which is power-limited and supervised by the control panel and the UDACT.
The wiring connections are made to the RS +, RS – and Shield terminals of TB1 on the UDACT.
The EIA-485 circuit cannot be T-Tapped and must be wired in a continuous fashion from the control
panel to the UDACT and, if installed, annunciators. The wire must be 12AWG to 18AWG twisted pair,
shielded cable with a Characteristic Impedance of 120 Ohms, +/– 20%. Limit the total wire resistance to
100 Ohms on the EIA-485 circuit. Do not run cable adjacent to, or in the same conduit as 120 volts AC
service, noisy electrical circuits that are powering mechanical bells or horns, audio circuits above 25
volts RMS, motor control circuits, or SCR power circuits.
Primary and Secondary Phone Lines
Modular jacks are used to interface the primary and secondary phone lines to the public telephone
network.
Communicator Fail Relay Driver
Relay driver output for Central Station communication failure is available.
Earth Ground
An earth ground connection to the UDACT is required for transient protection. One option allows
connection via Earth Gnd terminal on TB3 using solid 12 AWG (3.25mm
2 ) wire to provide lightning
protection (this connection is not required when the UDACT is mounted in a grounded metal enclosure
via the upper right mounting hole).
A second option allows connection via the upper right corner mounting hole using a metal standoff and
screws, attach to grounded metal cabinet.
