Wiring Connections
General The 4285 is wired between the control panel and the premises handset(s). It
listens for touch tones on the phone line and reports them to the control panel.
During on-premises phone access, it powers the premises phones; during off-
premises phone access, it seizes the line from the premises phones and any
answering machines.
Wiring 1. Make 12V (+) and (Ð) and data in and data out connections from the Phone
Module to the control*, using the connector cable supplied with the Phone
Module as follows:
Color Lead Terminal On Control

GREEN to DATA IN (terminal 8)*
BLACK to AUX Ð (terminal 7)*
RED to AUX + (terminal 6)*
YELLOW to DATA OUT (terminal 9)*
*ÊThese are the same connections as for remote keypads.
2. Insert the keyed connector at the other end into the mating header on the
Phone Module. See the 4285 Phone Module Wiring Connections diagram
on the next page
3. Connect terminals 1 through 5 on the Phone Module as shown in the
diagram and in the table below.
Note:ÊUse an RJ31X jack with a direct-connect cord and make all connections
exactly as shown. If the leads on the direct-connect cord are too short to reach
their assigned terminals, splice additional wires to them, as required.
TABLE 1
Ê4285 Terminal Connects to:
1. Phone In (Tip) Terminal (26) on control.
2. Phone In (Ring) Terminal (27) on control.
3. Phone Out (Tip) BROWN lead from direct-connect cord.
4. Phone Out (Ring) GRAY lead from direct-connect cord.
5. Ground Earth ground terminal (30) on control.
6. Audio Out 1 Future use
7. Audio Out 1 Future use
ADVISORY
If no touch tones are produced following access to the security system via the 2-
digit phone code 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 (26) & (27) on the control.
The wiring diagram shows the wiring connections that will provide proper
operation in most cases.
IMPORTANT: The phone module must be properly grounded to the panel in
order to operate. Attach a wire (22-18 gauge) from terminal 5 on the phone
module to terminal 30 on the VISTA-40 control.
CALLER ID NOTE: Some caller ID units may not be compatible with the 4285.
Refer to 4285 wiring diagram on next page for proper connections.
Programming The Control
For Phone Access
The following programming fields must be programmed when using a phone
module:
Using #93 Menu Mode-Device Programming, program the phone module (preset
at address 4) for phone module device type 05 and assign it to
partition 1.
*20 Phone Module Phone Code
*44 Ring Detection Count cannot be set to 0
*74/*75/*78 Alarm Report code for phone module faults (zone 87-99)
1*09 Zone Response Type for phone module (zones 87-93, type 05)
