Phone Line/Phone Module Connections - ADEMCO VISTA-20P Installation And Setup Manual

Installation Instructions

Phone Line/Phone Module Connections

1. Connect incoming phone line and handset wiring to
the main terminal block (via an RJ31X jack) as
shown in the Summary of Connections diagram at
the back of this manual. Wire colors represent the
colors of the cable to the RJ31X jack.
If using a phone module, continue with the following steps.
2. Make 12V (+) and (–) and data in and data out
connections from the phone module to the control,
using the connector cable supplied with the phone
module, then insert the keyed connector at the other
end of the connector cable into the header on the
phone module.
3. Connect Phone Module terminals as shown below.
Use an RJ31X jack with a direct-connect cord and
make all connections exactly as shown.
4. Caller ID Units: If a Caller ID unit is being used,
connect the unit directly to the "Handset" terminals
(21 & 22) on the control, as shown.
Phone Module Problems
If no touch tones are produced following access to the security system from on-premises (this problem may
arise in rare cases), it may be necessary to reverse the wires connected to terminals 3 and 4 on the phone
module and the wires connected to terminals (21) & (22) on the control. The wiring diagram shows the wiring
connections that will provide proper operation in most cases.
Connection to the incoming telco line via a RJ31X jack and direct-connect cord, as shown, is essential, even if
the system is not connected to a central station. The 4285 or 4286 will not function if this is not done and an
error signal (fast busy signal) will occur when trying to access the system via the phone.
The house phone lines (gray and brown wires) must be wired to the phone module terminals; not to the control
terminals. Otherwise, an error signal (fast busy signal) will occur when trying to access the system from an on-
premises phone.

Notes
• Use 4285 or 4286 Phone Modules.
Compatibility: 4286 Phone Modules must have
software version WA4286-15.1 or higher (refer to
the label on the square 4286 microprocessor chip).
• Only one phone module can be used and it can
only be connected to partition 1.
• The phone lines must be in service for the phone
module to function, even when accessing the
system from an on-premises phone.
• If you are also using an Audio Alarm Verification
(AAV) unit, refer to Audio Alarm Verification
(AAV) section for special wiring connections.
CAUTION: To reduce the risk of fire, use only No.
26 AWG or larger telecommunication line cord for
phone line connections.
