GE NX-4-EUR, Installation Manual

Page: 7 / 100

Auto-test
This feature will cause the panel to call the central station, in order to report a communicator
test at a specified interval (see location 51). Also, the auto-test report may be enabled ONLY
when the control panel is armed see location 37 segment 4).
Auxiliary outputs
The NX-4 has two programmable outputs that can be used to activate LED’s, sirens, flashes,
etc. (see the terminal description and locations 47-50).
Auxiliary power overcurrent
The NX-4 will light up the “Service” LED on the keypad whenever too much current is being
drawn from any device powered by the system. This condition can be reported to the central
station (see location 37 segment 3).
A+B alarm reporting (Sweden)
When this feature is enabled, a first trigger from a zone will send a BG report
(unverified alarm or B-alarm) for that zone. The B-alarm message will be written in the log. In
addition, a fix 30 minutes timer will start. If a zone is triggered for a 2nd time within the 30
minutes time frame, this zone will send a BA report (burglary alarm or verified alarm) to the
monitoring station. If there is no 2nd zone that was triggered within 30 minutes, the timer will
be cleared. A+B alarm reporting only works with intrusion zone types using the SIA formats.
When this feature is enabled, the standard cross-zoning feature will be in-active (see location
37 segment 3).
Box tamper
The NX-4 has an input for a normally closed tamper switch (see wiring diagram). The box
tamper can be programmed to report, and/or sound the siren and/or the keypad. These
terminals can be enabled or disabled by programming (see locations 37 segment 2 and 3, and
location 39).
Built In siren driver
The NX-4 has a built-in 112 dB siren driver. If desired, this built-in driver can easily be
converted to a 1 amp voltage output by programming (see location 37 segment 2).
Bypass toggle
This feature will enable the end user to toggle (turn on or off) the bypass of an interior zone
while the system is armed. This is done by pressing the [Bypass] key (see location 23 segment
2).
Call back
When this feature is enabled, the control panel will use the call back phone number to call the
download computer before it begins a download (see locations 21 and 22).
Cancel
If this feature is enabled, the NX-4 will send a “Cancel” report when the system is disarmed
and the [Cancel] button is pressed within 5 minutes of an alarm. Once the [Cancel] key has
been pressed, the “Cancel” LED will light up until the central station acknowledges the “Cancel”
report (see location 23 segment 3).
Chime
This feature can be turned on and off using the “chime” key. When the system is in the
disarmed state, a trip on selected zones will generate either a DING-DONG or a single tone
through the keypad sounder (depending on the keypad programming). This lowest level of
security can be enabled by zone; this is done by programming the appropriate zone
configuration for it, or by customizing its zone configuration (see locations 111-169).
