    It is very important for each subscriber to understand the difference
between the "code" used for arming and disarming the system and the "code"
recited to a central station operator to cancel an accidental or false alarm.
Alarm cancel codes may be set up in one of the following ways:

1.  If no code is defined for the account then the central station operators
    will accept the lower three digits of the account number as the alarm
    cancel code.  For example, the default cancel code for account number
    10287 is "287".

2.  If a code is defined for the account, the central station operators will
    accept it - and not the account number - to cancel an alarm.

3.  A separate code may be set up for each authorized security system user.
    To accomplish this, codes are entered in the call out list section of the
    subscriber's account.

4.  Different codes may be set up for different areas of the system.  An area
    is a group of one or more zones which you designate.  There is a limit of
    eight areas per account.

5.  A duress code may be set up for the account.  Each account may have only
    one duress code and it must be entered in the permanent instructions field
    of the subscriber's account.  When the duress code is given to an operator
    the operator will say thank you, hang up and immediately dispatch the 
    designated police agency for the account.  The operator will advise the
    police agency dispatcher that a duress code was given during the alarm
    verification call.

    Central station operators will require a code before accepting an
instruction to cancel a police or call out dispatch given by a person who is
at the protected premises.  No code is required to cancel a fire or medical
dispatch unless you have specified otherwise at the time the account was
created.  No code is required to cancel an alarm when the central station
operator has placed the call to a call out at a number which is not at the
protected premises.

    When assisting a subscriber in the selection of an alarm cancel code,
please consider all of the following factors:

1.  There is merit in making the cancel code the same as the arm/disarm code.
    The subscriber is not likely to forget it and will always provide it to 
    authorized users and visitors.  A subscriber using a numeric code of four
    digits or less may enter the code on the telephone key pad.  Central station
    telephones will display the code automatically.  This allows a subscriber's
    code to be given to the central station operator without being overheard by
    anyone standing nearby.

2.  When the increased security of a separate code is required, it is prudent
    to obtain a code word hint that the central station can use to prevent 
    unnecessary police response if the subscriber can't remember the code.
    This hint should be entered "CW Hint: son's middle name" in the permanent
    instructions field of the account.

3.  The alarm cancel code must be sixteen (16) characters or less, including
    spaces.

4.  The code should be something that all authorized users will easily
    remember.

5.  The code should be something which can be communicated easily to the
    central station operator.  Avoid using words which are not English or which
    cannot be spelled easily and phonetically.

6.  Never use a code which, when taken literally, requests assistance.  Codes
    such as "help" or "send the police" are not acceptable since the operator
    will probably take them literally and not cancel the alarm.

7.  Code words must be sufficiently unique so that they will not come up in
    normal conversation with the central station operator.  Using the subscriber's
    name as the code is a bad idea.

8.  Certain profane or inflammatory words will not be permitted to be saved
    as code words by the software.  When this happens it is necessary to
    choose a different code word.

    Central station operators will accept a code which is not an exact match or
which contains some additional verbage.  If the code word is "potato", the
operator will accept "french fried potatoes" or "Mr. Potato Head" as a correct
code.  A cancel code will not be rejected simply because it is in the wrong tense,
because it was placed in a phrase or a sentence, or because it was given in the
plural form instead of singular or vice versa.

    When an operator is given a four digit numeric code and the account has a non-
numeric code word (and the duress code, if any, is non-numeric) the operator will
explain that we are looking for the code word and not the number that is entered
on the key pad.

    When an operator is given a wrong code word the operator will look for a code
word hint in the permanent instructions field for the account.  If a hint is
available the operator will offer it and accept a new response.  If there is no
hint or the correct code word is not given in response to the hint the operator
will say "thank you", hang up and proceed to the next step which is usually to
dispatch.
