PART II: SYSTEM INSTALLATION AND SETUP
11.0 Telephone
Connections
The control panel connections (Terminals A and B –
see Figure 1 and Table 1) must be connected directly
to the incoming telephone line, which must provide a
direct connection to the telephone system (not via a
PABX or other network).
All wiring must be carried out within the master
terminal box provided by the telephone company and,
if fitted with a socket, this must not be used to
connect another device (blank master connecting
boxes are available from your telecom company upon
request).
Use insulating tape to cover the socket opening if
necessary. Make the connections using four-core
solid cable (type 1/0.5 CW1308) designed for
telephone use (do not use alarm connecting cable).
If the master box has IDC type terminals, use the
correct tool to make the connections, not a
screwdriver or other makeshift device. Ensure that the
earth connections are made using 1-mm cable to a
good ground connection. All cables should be
separated from the mains wiring by at least 300 mm.
See Figure 5 for details.

12.0 Phone Line Fault
The control panel has a circuit that tests the phone
line for voltage. The normal voltage on a telephone
line is approximately 48 VDC (24 VDC for some
phone systems). The phone line monitor senses
trouble when the voltage drops low enough (between
1 and 3 volts).
If the control panel senses trouble for 40 seconds, it
begins a phone line trouble response. Programming
determines the response type. See “Phone Line Fault
Response Options” in the DS7200V2 Expert
Programming Guide (P/N: 4998153891) for details.
Bad line might test OK: the telephone line test circuit
uses the voltage level to test the status of the phone
line. In some instances, a given telephone line might
be out of service without affecting the voltage on the
line. The phone line monitor cannot recognize this
trouble condition.
13.0 Communication Failure (Comm Fail)
The control panel routes reports to two routing
destinations. Each of the destinations can be
programmed with two phone numbers or IP
addresses. The numbers in { } are the numbers
assigned to control panel events.
Communication Attempt Tables on page 121 shows
the circumstances when Communication Failure
Events are created. When a Comm Fail occurs, the
control panel responds as follows:
1. Clear (dump) the initiating report and any
pending reports from the buffer for the destination
where the Comm Fail event occurred.
2. Create a Comm Fail {69} or Alternate Comm Fail
{70} report that includes the Destination Number
(1 or 2). The Alternate Comm Fail report is used
when an alternate communications path is used
(for example, SAFECOM IP communication).
3. The Comm Fail, Comm Restoral {71}, Alternate
Comm Restore {72} reports follow the System
Status Reports routing.
4. If the Comm Fail occurred on Destination 1 and
System Status Reports routing is set to
Destination 2 or set to Destination 2 on
Destination 1 fail, then send Comm Fail report.
5. If the Comm Fail occurred on Destination 1 and
System Status Reports routing is set to
Destination 1 then send a Comm Restore report
with the next report for destination 1.
6. If the Comm Fail occurred on Destination 2 and
System Status Reports routing is set to
Destination 1, then send Comm Fail report.
7. If the Comm Fail occurred on Destination 2 and
System Status Reports routing is set to
Destination 2 then send a Comm Restore report
with the next report for Destination 2.
8. If a Comm Fail report is sent successfully to the
other destination, a Comm Restore event should
be sent when there is a successful
communication on the failed destination.
