from the mounting plate by pushing the locking tab 
and turning the detector counter-clockwise.
Hold the unit with the battery compartment facing 
you, and the imprinted wording right-side up. Install 
the first two batteries in the row nearest to you, with 
the + terminals facing left. Next, install the middle two 
batteries with the + terminals facing to the right. Place 
your thumb over the centre of these four batteries to 
keep them in place. Install the last two batteries, with 
their + terminals facing to the left, by snapping them past the nylon retainer.
Wireless Keys
WLS919-433
The WLS919 wireless key requires two lithium CR2032 batter-
ies. To replace the batteries, open the key’s plastic housing by 
inserting a flathead screwdriver along the side of the unit;  
carefully twist the screwdriver to separate the top and bottom 
plastic. Remove the old batteries. Insert the new batteries according to the dia-
gram at right and reassemble the key’s plastic housing. 
NOTE: The polarity of the batteries must be observed.
After 
Installing 
New BatteriesAfter you change the batteries on your system, the system may announce trouble 
conditions. A zone tamper should be displayed for each detector that had batter-
ies changed. A zone fault may also be displayed and announced for these detec-
tors. Refer to Checking Trouble Conditions on page 19 for information on 
checking Zone Faults and Zone Tampers. 
Be sure to perform a complete test of your system after new batteries are installed 
to ensure that all detectors are working properly (see Testing Your System on 
page 20).

Glossary
Access codeA 4- or 6-digit code you enter on the keypad to turn your system on or off, or to 
use other system features.
AlarmWhen a zone is violated (e.g., a smoke detector detects smoke, a motion detector 
senses movement, a door with a contact is opened), it will trigger an alarm.
Intrusion (burglary) alarm: An alarm triggered by an intrusion detector (e.g. 
motion detectors, glassbreak detectors, door/window contacts). Usually occurs 
when the system is on. Intrusion alarms sound with a steady siren.
Fire alarm: An alarm triggered by fire, smoke or heat detectors. Fire alarms may 
be triggered at any time, whether the system is on or off. Fire alarms sound with a 
pulsing siren.
AnnounceVoice notification by the NT9010 of a variety of system conditions.
Audible exit 
faultA feature that warns you of an improper exit (e.g. door not completely shut) when 
you attempt to turn on your system. Helps to prevent false alarms.
Away armingTurning on the system so that all the detectors (perimeter and interior) are on. 
(Used when everyone is away from the premises.)
Bypassing a 
zoneTurning off a detector temporarily. When you bypass a zone, the detector for that 
zone will not monitor activity in the zone and will not be able to trigger an alarm, 
until the system has been turned off, then on again.
Central 
stationIf remote monitoring is enabled, your system will send alarms, troubles and emer-
gency messages to the central station. If necessary, the central station will then 
notify authorities in your area.
DetectorA part of the system that can detect and report problems (e.g. a motion detector 
can tell if there is movement in a room).
Emergency 
messageA message sent to the central station when one of the 3 pairs of emergency keys 
( ) is pressed and held for two seconds. Your installer must program these 
keys, or they will not work.
Entry timeA timer programmed by your installer. It starts when you enter an area of the sys-
tem that is on. You must enter an access code to turn the system off before the 
timer runs out, or else an alarm will be triggered. 
						

							30
Entry/exit 
doorsYour installer will program the doors you usually use to enter or exit the premises 
as the entry/exit doors. These doors are programmed with entry and exit times so 
that you can turn the system on and off without causing a false alarm.
Exit timeA timer programmed by your installer. It starts when you turn on your system to 
allow you a period of time to leave the premises. At the end of the exit time, the 
system will be on.
Local 
telephoneIf your NT9010 system is connected to your home/office telephone line, you may 
be able to use a telephone key to access the system.
Master codeThe master code is, a 4- or 6- digit access code, is used to set system options, to 
turn the system on and off, and to program other access codes.
Remote 
telephoneIf your NT9010 system is connected to your home/office telephone line, you may 
be able to use an off-premise (remote) telephone to access the system.
Stay modeTurning on the system so that only the perimeter zones (see zone definitions, 
below) are on. (Use when one or more people will stay on the premises.)
Tr o u b l eThe NT9010 controller continuously checks the system for problems. If the control-
ler finds a problem (trouble), it will indicate this at the keypad. See Checking 
Trouble Conditions on page 19 for a list of possible trouble conditions, and how 
they are displayed or announced.
ZoneA limited area of the premises monitored by a detector (smoke detector, door/win-
dow contact, motion detector, glassbreak detector, etc.).
Perimeter zone: A zone that detects intrusion from outside the premises (e.g., 
door contact on an outside door, glassbreak detector).
Interior zone: A zone that detects intruders who have already entered (e.g., a 
motion detector).
Fire zone: A zone that has a heat or smoke detector.

WA R NI NG  Please Read Carefully
Note to InstallersThis warning contains vital information. As the only individual in contact with sys-
tem users, it is your responsibility to bring each item in this warning to the attention
of the users of this system.
System FailuresThis system has been carefully designed to be as effective as possible. There are
circumstances, however, involving fire, burglary, or other types of emergencies
where it may not provide protection. Any alarm system of any type may be com-
promised deliberately or may fail to operate as expected for a variety of reasons.
Some but not all of these reasons may be:

 Inadequate Installation
A security system must be installed properly in order to provide adequate protec-
tion. Every installation should be evaluated by a security professional to ensure that
all access points and areas are covered. Locks and latches on windows and doors
must be secure and operate as intended. Windows, doors, walls, ceilings and other
building materials must be of sufficient strength and construction to provide the
level of protection expected. A reevaluation must be done during and after any con-
struction activity. An evaluation by the fire and/or police department is highly rec-
ommended if this service is available.

 Criminal Knowledge
This system contains security features which were known to be effective at the time
of manufacture. It is possible for persons with criminal intent to develop techniques
which reduce the effectiveness of these features. It is important that a security sys-
tem be reviewed periodically to ensure that its features remain effective and that it
be updated or replaced if it is found that it does not provide the protection expected.

 Access by Intruders
Intruders may enter through an unprotected access point, circumvent a sensing
device, evade detection by moving through an area of insufficient coverage, discon-
nect a warning device, or interfere with or prevent the proper operation of the sys-
tem.

 Power Failure
controllers, intrusion detectors, smoke detectors and many other security devices
require an adequate power supply for proper operation. If a device operates from
batteries, it is possible for the batteries to fail. Even if the batteries have not failed,
they must be charged, in good condition and installed correctly. If a device operates
only by AC power, any interruption, however brief, will render that device inopera-
tive while it does not have power. Power interruptions of any length are often
accompanied by voltage fluctuations which may damage electronic equipment such
as a security system. After a power interruption has occurred, immediately conduct
a complete system test to ensure that the system operates as intended.

 Failure of Replaceable Batteries
This system’s wireless transmitters have been designed to provide several years of
battery life under normal conditions. The expected battery life is a function of the
device environment, usage and type. Ambient conditions such as high humidity,
high or low temperatures, or large temperature fluctuations may reduce the
expected battery life. While each transmitting device has a low battery monitor
which identifies when the batteries need to be replaced, this monitor may fail to
operate as expected. Regular testing and maintenance will keep the system in good
operating condition.

 Compromise of Radio Frequency (Wireless) Devices
Signals may not reach the receiver under all circumstances which could include
metal objects placed on or near the radio path or deliberate jamming or other inad-
vertent radio signal interference.

 System Users
A user may not be able to operate a panic or emergency switch possibly due to per-
manent or temporary physical disability, inability to reach the device in time, or
unfamiliarity with the correct operation. It is important that all system users be
trained in the correct operation of the alarm system and that they know how to
respond when the system indicates an alarm.

 Smoke Detectors
Smoke detectors that are a part of this system may not properly alert occupants of a
fire for a number of reasons, some of which follow. The smoke detectors may have
been improperly installed or positioned. Smoke may not be able to reach the smoke
detectors, such as when the fire is in a chimney, walls or roofs, or on the other side
of closed doors. Smoke detectors may not detect smoke from fires on another level
of the residence or building.Every fire is different in the amount of smoke produced and the rate of burning.
Smoke detectors cannot sense all types of fires equally well. Smoke detectors may
not provide timely warning of fires caused by carelessness or safety hazards such as
smoking in bed, violent explosions, escaping gas, improper storage of flammable
materials, overloaded electrical circuits, children playing with matches or arson.
Even if the smoke detector operates as intended, there may be circumstances when
there is insufficient warning to allow all occupants to escape in time to avoid injury
or death.

 Motion Detectors
Motion detectors can only detect motion within the designated areas as shown in
their respective installation instructions. They cannot discriminate between intrud-
ers and intended occupants. Motion detectors do not provide volumetric area pro-
tection. They have multiple beams of detection and motion can only be detected in
unobstructed areas covered by these beams. They cannot detect motion which
occurs behind walls, ceilings, floor, closed doors, glass partitions, glass doors or
windows. Any type of tampering whether intentional or unintentional such as
masking, painting, or spraying of any material on the lenses, mirrors, windows or
any other part of the detection system will impair its proper operation.
Passive infrared motion detectors operate by sensing changes in temperature. How-
ever their effectiveness can be reduced when the ambient temperature rises near or
above body temperature or if there are intentional or unintentional sources of heat
in or near the detection area. Some of these heat sources could be heaters, radiators,
stoves, barbeques, fireplaces, sunlight, steam vents, lighting and so on.

 Warning Devices 
Warning devices such as sirens, bells, horns, or strobes may not warn people or
waken someone sleeping if there is an intervening wall or door. If warning devices
are located on a different level of the residence or premise, then it is less likely that
the occupants will be alerted or awakened. Audible warning devices may be inter-
fered with by other noise sources such as stereos, radios, televisions, air condition-
ers or other appliances, or passing traffic. Audible warning devices, however loud,
may not be heard by a hearing-impaired person.

 Telephone Lines
If telephone lines are used to transmit alarms, they may be out of service or busy for
certain periods of time. Also an intruder may cut the telephone line or defeat its
operation by more sophisticated means which may be difficult to detect.

 Insufficient Time
There may be circumstances when the system will operate as intended, yet the
occupants will not be protected from the emergency due to their inability to respond
to the warnings in a timely manner. If the system is monitored, the response may
not occur in time to protect the occupants or their belongings.

 Component Failure
Although every effort has been made to make this system as reliable as possible, the
system may fail to function as intended due to the failure of a component.

 Inadequate Testing
Most problems that would prevent an alarm system from operating as intended can
be found by regular testing and maintenance. The complete system should be tested
weekly and immediately after a break-in, an attempted break-in, a fire, a storm, an
earthquake, an accident, or any kind of construction activity inside or outside the
premises. The testing should include all sensing devices, keypads, consoles, alarm
indicating devices and any other operational devices that are part of the system.

 Security and Insurance
Regardless of its capabilities, an alarm system is not a substitute for property or life
insurance. An alarm system also is not a substitute for property owners, renters, or
other occupants to act prudently to prevent or minimize the harmful effects of an
emergency situation.
