Section 18: FALSE ALARM REDUCTION FEATURES
This section provides the following information:
• General information about false alarms
• Exit Error Logic and related reports
• Exit Delay Reset
• Cross-Zoning
• Call Waiting Defeat
General Information
This control supports features which help minimize false alarms from occurring.
Most false alarms occur either upon exiting the premises, or because of a zone
which tends to go into alarm either due to environmental factors, or because the
zone's resistance to the control may be on the edge of acceptability. We call this
condition a "swinger."
Features which prevent false alarms due to these circumstances are:
• Exit Error Logic and related reports
• Exit Delay Reset
• Cross-Zoning
Exit Error Logic
UL
This feature is not suitable for use on a UL commercial burglary installation.
This feature is intended to reduce the incidence of false alarms due to exit doors
that are left open after the exit delay has expired. If this feature is enabled in
program field 1*20, the following will occur:
At the end of the exit delay, if a door is left open or an interior zone is faulted, the
system will start the entry delay period, and will sound the bell(s),siren(s) and
keypad sounders for the duration of entry delay. This gives the user time to re-
enter the premises and disarm the system before exit error occurs.
If the user does not re-enter the premises and disarm the system, the system will
bypass the faulted entry/exit and/or interior zone(s). The rest of the system will
be armed. In addition, the following dialer reports will be sent to the central
station if programmed:
• Exit Error by User (not sent if using ADEMCO High Speed format)
• Exit Error by Zone (Sent as regular alarm if using ADEMCO High Speed
format)
• Bypass reports
Recent Close Report
Another report, designed to notify the central station that an alarm has occurred
within five minutes of arming, is called the Recent Close report. This report, as
well as the Exit Error reports, are programmed in #93 Report Code Programming
mode.
Exit Delay Reset
UL
This feature is not suitable for use on a UL commercial burglary installation.
This feature is designed to allow an operator to re-enter the premises to retrieve
a forgotten item without triggering an alarm. This feature is enabled in program
field 1*21, and works in the following way:
