NX-8 Control

begin a new trip count where the next alarm will set the ‘counter’ to 1. If immediate restore is enabled in location 37,

the alarms (and restores, if enabled) will be sent as they occur. If immediate restore is not enabled, a second or

subsequent alarm will not be sent until the siren times out. (See location 37 and 38, page 23) Factory default is 1.

Telephone Line Monitor - The NX-8 has a Telephone Line Monitor that monitors the voltage and current of the

telephone line for a detection of a faulted phone line. This condition can also be reported to the central station. If the

report is enabled, only the Telephone Line Restore will be reported unless the NX-870 is being used. (See locations
37, 39, and 40, pages 23-24)

Temporal Siren Disable - If disabled, the Fire Siren will be steady and Fire Voltage Out will be the same as Burglary

(continuous). Otherwise, the Fire Siren will be temporal. (See location 37, page 23) NOTE: For UL installations,
do NOT disable.

Tone Sniff Answering Machine Defeat- If enabled, only one call is required to defeat the answering machine. To use

this feature you must have a Hayes 1200 Smart Modem. From the computer, call the panel as normal. When the

answering machine answers, the panel will hear the tones from the modem and seize the phone line for a download.
(See location 21, page 18)

Two Call Answering Machine Defeat - If enabled, to defeat an answering machine, two telephone calls must be

made to the premises. On the first call, let the phone ring one or two times. The control panel will detect these rings

and start a 45 second timer, during which, the control panel will answer the next call on the first ring. This is not
recommended for commercial applications. (See location 21, page 18)

Walk-Test Mode - If enabled, entering [ ] [Chime] followed by a user code will allow a walk-through zone test where

all zones become silent and local (non-reporting). During this test the chime light will flash on the LED keypad. Each

time a zone is faulted, the zone light on the LED keypad will illuminate and the chime will sound. The number of the

faulted zone(s) will be displayed on the LCD keypad. It will also be entered into alarm memory and the internal log.

To exit at any time during this mode, enter a user code. Otherwise the AWalk-Test Mode@ will automatically exit after

15 minutes. (See location 41, page 24)

Wireless Sensor Missing/Low Battery - The NX-8 will send a report to the central station when a wireless sensor

has detected a low battery or has not reported to the receiver. The "Service" LED will illuminate when either condition

exists. (See location 37, page 23)

Zone Bypassed Sounder Alert- If this feature is enabled, the NX-8 will beep the keypad sounder upon arming if a

zone is bypassed. (See location 23, page 19)

Zone Doubling - This feature allows you to use the eight zones on the panel as sixteen normally closed zones. When

this feature is used European double E.O.L. configuration cannot be used on the first sixteen zones. THIS FEATURE

DOES NOT INCREASE THE TOTAL NUMBER OF AVAILABLE ZONES BEYOND 48. If one of the sixteen zones

must be a fire zone, it must be one of Zones 1 to 8. The corresponding upper zone will become unavailable. For

example, if Zone 6 is a fire zone, then Zone 14 will not be available. (See location 37, page 23)

Zone Types (Configurations) - The NX-8 has 20 programmable Zone Types that determine how each zone will

function and report. The default Zone Types are listed on page 20. (See locations 111-149, pages 35-38)
