On-Premises Phone Access Restrictions
The system cannot be accessed from an on-premises phone under the
following conditions:
•
Phone line is busy
•
Phone is ringing
•
Downloading is in progress*
•
Phone line is out of order.
*
Downloading is the process of remote programming of your security
system by the central monitoring station over the phone lines, using their
computer.
However, there are some conditions under which the system can still be
accessed from an on-premises phone, even though the phone line is in use.
These are:
•
If on the phone during the entry delay period:
The system may be accessed if you are on an on-premises phone during the
entry delay period (for example, the system is armed, you are talking on the
phone, and a family member enters through an entry/exit door).
During this period, the system may be disarmed without hanging up by
entering your 2-digit phone code, followed by the DISARM command
sequence. There will be no phone confirmation of the command, and you will
have to listen for confirmation "beeps" from the nearest wired keypad. Phone
disconnect will not occur, and the conversation can be continued after the
DISARM command has been keyed.
The person at the other end could possibly record the touch tones as they are
being entered (your phone code could then be ascertained from the sound of
the tones). If there is any concern in this regard, the phone conversation should
be terminated first, or the system disarmed in the conventional way via the wired
keypad while keeping the person on hold.
•
If the System is Communicating with the Alarm Monitoring Company
(such as when your security system is reporting an alarm):
Although the phone line is in use during this period, and therefore no dial
tone will be present when the on-premises phone is picked up, the system will
annunciate the following phone message: "SYSTEM DIALING CALL TO
CENTRAL STATION" (repeated periodically). It is possible to access the
system at this time by entering your 2-digit phone code during the pause
between annunciations of the above message.
