Immediate restore by zone
The NX-4 can be programmed to send alarm and restore reports as soon as they occur,
or to wait until the siren time has expired or the system has been disarmed. (see location
37 segment 2).
Internal event log
Up to 512 events can be stored in memory together with the date and time of the event.
These events can be viewed later on via the LCD keypad, or by downloading. All
reportable events are reported 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 (see location 23 segment 1).
Keypad shutdown mode
This feature will extinguish all the LED’s on the keypad, except the “Power” LED, after 60
seconds have elapsed without a keypress. Pressing a valid user code (not an installer
code) will light up all the LED’s (see location 41, segment 1, option 5). This option
requires bilingual LCD keypads. This option is an alternative for LED-extinguish.
Keypad sounder control
The NX-4 can be programmed to sound the keypad sounder for certain events (see
location 39).
Keypad tamper
If this option is enabled, the NX-4 will disable the keypad for 60 seconds, and will
communicate a tamper signal to the central station whenever 30 keypresses are entered
without producing a valid code (see location 23 segment 1).
Keyswitch arm/disarm
Any zone on the NX-4 can be programmed as a momentary or maintained keyswitch
zone. If a zone has been programmed as a momentary keyswitch, momentary shorts on
this zone will arm/disarm the control. A zone can be also being programmed as a
maintained keyswitch. The control panel will be armed as long as such a zone is shorted.
If opening/closing reports are sent, the user code will be 99 (see “default zone
configurations”)
LED extinguish
This feature will extinguish all the LED’s on the keypad, except the “Power” LED, after 60
seconds have elapsed without a keypress. Pressing any numeric key will light up all the
LED’s (see location 23 segment 2).
Local programming lockout
This feature will disable programming of all locations, or for specified locations, from the
keypad (see location 21).
Log full report
A report can be sent to the central station when the event log is full (see location 37
segment 4).
Lost clock service light
The NX-4 can be programmed to light up the “Service” LED on a LED keypad or give a
“Service” message on a LCD keypad when the internal clock time is invalid due to power
loss. On LCD keypads, if programmed to show the system time, a “Set Clock, *97”
message will always be displayed (see location 37 segment 5).
