Fire alarm verification
When this feature is enabled, the NX-4 will verify a fire alarm by requiring more than one trip
on a smoke detector (the same or another one) within a specified time (120-255 seconds)
before it generates an alarm (see location 40 segment 9).
Force arming
If this option is enabled, the NX-4 can be "Force Armed" when zones have been violated. In this
condition, the "Ready" LED will flash if a "Force Armable" zone is not secure. At the end of the
exit delay, these zones will become bypassed, unless the option "No auto-bypass for force
armable zones" is set (location 23, segment 5 option 1). If these zones become secured at any
time during the arming cycle, they will be unbypassed and will become 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 not to report bypass even if "Bypass Report" is enabled
(see locations 37 segment 5, and 111-169 segment 2).
Group bypass
A designated group of zones can be programmed to bypass by pressing [Bypass]-[0]-[0]-
[Bypass] prior to arming (see locations 111-169 segment 2).
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. A keyswitch zone can arm
in AWAY or STAY mode (see location 23, segment 4, option 8). If opening/closing reports are
sent, the user code will be 99 (see "default zone configurations")
