NX-4 Control
Page 5
Exit Error
If enabled, the NX-4 will send an "Exit Error Report" if an entry/exit zone is faulted at the instant the exit delay
expires. This report will be sent along with the user number that armed the system, if the panel is not disarmed
before the entry delay expires. The alarm report will also be sent. Even if this feature is not enabled, the siren will
sound if any entry/exit zone is faulted at the instant the exit delay expires. (Loc. 23, page 16)
Expander Trouble
The NX-4 will report expander trouble to the central station if enabled. This condition will illuminate the "Service"
LED on the keypad even if not reported. NOTE: The keypads are considered expanders. The number of the
expansion devices reported can be found on page 35. (Loc. 37, page 17)
Fail to Communicate
The NX-4 will illuminate the "Service" LED if a report fails to reach the central station. If enabled, when the next
report is successfully communicated, a Fail to Communicate code will be reported. (Loc. 37, page 17)
Fire Alarm Verification
When enabled, the NX-4 will verify a Fire alarm by requiring more than one trip on a smoke detector within a
specified time before creating an alarm. NOTE: For household systems, the Fire Alarm Verification feature is NOT
approved for use in California. This feature shall not be programmed into the control unit. (Loc. 40, page 18)
Force Arming
When enabled, the NX-4 can be Force Armed with zones violated. Under this condition, if a force armable zone is
not secure, the "Ready" LED will flash. At the end of the exit delay, these zones will become bypassed. If these
zones become secured any time during the arming cycle, they will be unbypassed and active in the system. If
"Bypass Report" is enabled, the force arming zones can be programmed to report bypass when they are Force
Armed (default), or to not report bypass even if "Bypass Report" is enabled. (Loc. 37, and 111-149, pages 17
& 24-25 NOTE: For UL installations, this feature shall be disabled.)
Group Bypass
A designated group of zones can be programmed to bypass by pressing [Bypass]- [0]-[Bypass]- [Bypass] prior
to arming. (Loc. 111-149, pages 24-25 NOTE: For UL installations, this feature shall be disabled.)
Immediate Restore By Zone
The NX-4 can be programmed to send alarm and restore reports as soon as they occur, or wait until the siren time
has expired. (Loc. 37, page 17)
Internal Event Log
Up to 185 events can be stored in memory along with the date and time of the event. These events can later be
viewed through downloading or on the LCD keypad. All reportable events report to the log.
Keypad Activated Panics
The NX-4 has three keypad activated panics that will send reports to the central station: Auxiliary 1 (Fire), Auxiliary
2 (Medical), and Keypad Panic. Auxiliary 1 will activate the steady (Fire) siren, Auxiliary 2 will sound the keypad,
and the Keypad Panic can be programmed to be silent or audible (sound siren). (Loc. 23, page 16)
Keypad Sounder Control
The NX-4 can be programmed to sound the keypad sounder for certain events. (Loc. 39, page 18)
Keypad Tamper
If enabled, the NX-4 will disable the keypad for 60 seconds and communicate a tamper signal to the central station
if 30 keypresses are entered without producing a valid code. (Loc. 23, page 16)
LED Extinguish
This feature will extinguish all LED =s on the keypad, except the "Power" LED, after 60 seconds without a keypress.
Pressing any numeric key will illuminate all LED =s. (Loc. 23, page 16)
