End of line resistor defeat
The NX-4 can be programmed to make zones 1-4 for normally closed operation only,
eliminating the need of the end of line resistors on these zones. When a zone is programmed
for normally closed operation, a short on that zone will not change the loop condition, and an
open on that zone will produce a faulted condition. This feature will be ignored by any priority
zone (see locations 110-169).
Entry-guard
This unique low level arming mode has been developed to reduce the most common source of
false alarms. When armed in the "Stay Instant" mode, opening any zone designated as an
"Entry Guard Zone" will initiate the keypad sounder and start the entry delay before
generating an alarm. All the other zones will function as normal. This arming mode will
encourage system owners to use their systems more frequently when the premises are
occupied (see locations 111-169).
Exit error / Exit error Delay 1
If the option Exit error is enabled on location 23 segment 3, the NX-4 will send an "Exit Error
Report" when an entry/exit zone is faulted, at the instant the exit delay expires. If also the
option "Exit Error Delay 1" is enabled on location 37 segment 7, the NX-4 will send an "Exit
Error Report" when only an entry/exit delay 1 zone is faulted, at the instant the exit delay
expires. An entry/exit delay 2 zone that is faulted at the end of the exit delay will not have
siren activation and will not log an exit error. The "Exit Error Report" will be sent together with
the user number that was used to arm the system, provided that the panel is not disarmed
before the entry delay expires. The alarm report will also be sent. If both features "Exit Error
Report" and "Exit Error Delay 1" are not enabled the siren will sound if any entry/exit zone is
faulted, as soon as the exit delay expires. If the option "Exit Error Delay 1" is enabled, the siren
will sound if only an entry/exit 1 zone is faulted (see location 23 segment 3 and location 37
segment 7).
Expander trouble
The NX-4 will report expander trouble to the central station if this option is enabled. This
condition will light up the "Service" LED on the keypad, even if it is not reported.
NOTE: The keypads are considered to be expanders. The number of expansion devices that
are reported can be found in appendix 3 (see location 37 segment 3).
Early to Open/ Late to Close
If an opening occurs before the opening and closing times, the NX-4 will send an "Early Open"
report. If it fails to close on or before the designated closing time, the NX-4 will send a "Late to
Close"report. (see location 23 segment 4)
Fail to communicate
The NX-4 will light up the "Service" LED if a report fails to reach the central station. If this
option is enabled, a fail to communicate code will be reported when the next report is
successfully communicated. A fail to communicate is always logged as "data lost" (see
location 37 segment 4).
Final set door
If this feature is enabled, it will only be applicable for secondary entry/exit zones (f.e.
configuration group 9 or 19). If the final set door option is enabled, the exit time will
immediately expire as soon as the secondary entry/exit zone (type 9 or 19) becomes ready
again. This feature can only be used in combination with magnetic contracts (see location 23,
segment 2, option 8).
