Protection Against Outside Tampering
In addition to counting the input attempts for the phone code and the
system code, some control panels also prevent attempts by an
unauthorized person to access the system from an outside phone.
After 4 unsuccessful calls are made (including "access attempts"
within an armed or disarmed period), remote phone access will be
automatically turned off, and can only be turned on again from within
the premises.
Whenever remote access is turned off due to tampering, you will be
warned of the tampering instead of a prompt for codes on a call-in.
The system will annunciate
"CALL-IN TO SYSTEM OFF, SEE
SYSTEM KEYPAD", and ignore all key depressions thereafter, until
hang-up. The system's wired keypad may also beep approximately
every 20 seconds, with an Alpha keypad displaying CALL–IN
TAMPER, and a fixed-word keypad displaying "CI.”
Before remote phone access can be turned on again after a tamper message,
the system must be cleared by keying an OFF sequence (system security code
plus OFF) twice.
What To Do In Case of Repeated Tamper Messages
Remote Phone Access will be turned off automatically as a result of
possible tampering such as would be caused by improper keying of
codes on a call-in from outside. If this occurs repeatedly over a short
space of time, exercise caution if the improper keying was not caused
by you or a family member. Some unauthorized person may be
attempting to access your security system from outside, and you
should consider NOT turning Remote Access on again for a period of
time.
