Calling for 
HelpThe NT9010 has three pairs of emergency keys. Using these keys you can send an 
immediate Fire, Auxiliary or Medical and Panic message to your central station.
IMPORTANT:The Fire, Auxiliary or Medical, and Panic keys will NOT func-
tion unless they have been turned ON by the installer. If your installer has 
turned these keys ON, and enabled audible feedback, holding down the 
keys for two seconds will cause the keypad sounder to beep indicating that 
the alarm input has been accepted and transmission to the central station 
is underway.
From the NT9010 controller
Press both   keys for two seconds to send a Fire message, and to trigger a 
fire alarm on the system.
Press both   keys for two seconds to send an Auxiliary message.
Press both   keys for two seconds to send a Panic message.

Section 5: Using Advanced Functions
This section describes how to perform more specialized functions: turning off spe-
cific detectors (bypassing zones), turning the door chime on or off, checking sys-
tem troubles, and testing your system. 
Tu r n i n g  O f f  
Part  of Your 
System 
(Bypassing 
Zones)Sometimes, you may need to temporarily turn off a detector:
 if you need to go into a protected area while the system is turned on 
 or, if a detector is temporarily out of service but you need to turn on the system 
This is called “bypassing”. When you bypass a detector, it will not turn on the next 
time you turn on your system. 
Detectors (zones) cannot be bypassed once the system is on. Bypasses on detec-
tors are automatically cancelled each time the system is turned off. You must 
bypass the detectors again, if required, before you turn the system on again. 
1. Start with the system turned off. Press  .
2. If the system asks for your [access code], enter it now.
3. Enter the two-digit number (01-32) of the detector you want to turn off (bypass). 
The system will announce the zones (detectors) that are bypassed: “There are 
(number) zones bypassed: {Zone XX}, etc...To exit, press [#].”
TIP: To find out the number of a detector, check in Zone Information on page 
32.
4. To turn a detector back on, enter the two-digit number of the zone (01-32). 
The system will return the zone to normal status and the zone will be ON when 
the system is next armed.
The system will announce any other zones (detectors) which are bypassed: 
“There are (number) zones bypassed: {Zone XX}, etc...To exit, press [#].”
5. When you are finished turning off detectors, press  .
6. The next time you turn on your system, the bypassed detectors will not turn 
on. When you turn your system off again, all zones will return to normal (they 
will not be bypassed).
NOTE: Bypassed detectors will not be able to sound an alarm - this reduces 
your level of security. If a detector is not working, call a service technician 
immediately so that the problem can be resolved and your system returned 
to proper working order.
NOTE: For security reasons, your installer may program the system to pre-
vent you from turning off certain detectors (for example, smoke detectors).
NOTE: If you have 24-hour zones on your system, they will stay bypassed 
until you turn off the bypass using the steps above (ask your installer for 
more information).

Checking 
Trouble 
ConditionsYour system continuously checks for a number of possible trouble conditions. If 
one of these trouble conditions occur:
 the yellow (System) light will be ON until the trouble is fixed
 the keypad will beep twice every 10 seconds until it is acknowledged by press-
ing any key
 the NT9010 will say “System Trouble” when announcing the status of the system
NOTE: A Trouble condition reduces the level of security your system pro-
vides. Call your installing company for service.
To listen to an announcement of the troubles that are present, press  . 
To exit the trouble announcement, press  .
Here is a list of the various trouble conditions that your system might announce: 
Announcement: Problem and how it should be addressed:
“Service is required, 
press [1].”
“Low Battery”
“Remote Bell 
Trouble”
“Bad Module 
Placement”
“System Fault”If this message is announced, call for service. When the system 
announces this message, one or more of the following troubles 
may then be announced.
“Low Battery” means the battery voltage has fallen below the 
normal operating voltage.
“Remote Bell Trouble” means the system is having a problem 
communicating to the remote bell.
“Bad Module Placement” means during the installation, not all 
of the devices on your system were properly tested for commu-
nication integrity.
“System Fault”means there is an internal system error.
“AC Power Trouble.” Electrical power to the system has been interrupted. Check your 
fuse box or circuit breaker to ensure that the electricity supply 
for the system is on. If this does not correct the problem, call for 
service. The NT9010 may go to sleep to conserve the backup 
battery if the AC power is out for more than 30 seconds. If this 
happens, you can “wake up” the unit by pressing and holding 
 for 2 seconds.
“Phone line trouble.” Your system has detected a problem with the telephone line. If 
this problem does not correct itself, or happens frequently, call 
for service.
“Communication 
trouble.”Your system has been unsuccessful in communicating an event 
to your central station. If you hear this message, call for service 
immediately.
“ Zone Fault, press 
[5].”Your system has detected a fault on one or more zones (detectors). 
Press  , and the system will announce which zones have a fault. If 
you are unsure of how to clear a zone fault, call for service.
“Zone tamper, press

Section 7: Fire Safety
Read this section carefully. It contains important information about fire safety.
Household 
Fire Safety 
AuditMost fires occur in the home. To minimize this danger, we recommend that a 
household fire safety audit be done and a fire escape plan be created.
1. Are all electrical appliances and outlets in a safe condition? Check for frayed 
cords, overloaded lighting circuits, etc. If you are uncertain about the condition 
of your electrical appliances or household service, have a professional evaluate 
these units.
2. Are all flammable liquids stored safely in closed containers in a well-ventilated, 
cool area? Cleaning with flammable liquids should be avoided.
3. Are fire hazardous materials (e.g., matches) well out of reach of children?
4. Are furnaces and wood burning appliances properly installed, clean and in 
good working order? Have a professional evaluate these appliances.
Fire Escape 
PlanningThere is often very little time between the detection of a fire and the time it 
becomes deadly. Therefore it is very important to develop and rehearse a family 
escape plan.
1. Every family member should participate in developing the escape plan.
2. Study the possible escape routes from each location within the house. Since 
many fires occur at night, special attention should be given to the escape 
routes from sleeping quarters.
3. Escape from a bedroom must be possible without opening the interior door. 
Consider the following when making your escape plans:
 Make sure that all exterior doors and windows are easily opened. Ensure that 
they are not painted shut, and that their locking mechanisms operate smoothly.
 If opening or using the exit is too difficult for children, the elderly, or the handi-
capped, plans for rescue should be developed. This includes making sure that 
those who are to perform the rescue can promptly hear the fire warning signal.
 If the exit is above the ground level, an approved fire ladder or rope should be 
provided as well as training in its use.
 Exits on the ground level should be kept clear. Be sure to remove snow from 
exterior patio doors in winter. Outdoor furniture or equipment should not block 
exits.
 Each person should know of a predetermined assembly point where everyone 
can be accounted for (e.g., across the street or at a neighbor’s house). Once 
everyone is out of the building, call the Fire Department. 
						

							24
 A good plan emphasizes a quick escape. Do not investigate or attempt to fight 
the fire, and do not gather belongings or pets as this wastes valuable time. 
Once outside, do not re-enter the house. Wait for the fire department.
 Write the fire escape plan down and rehearse it frequently so that should an 
emergency arise, everyone will know what to do. Revise the plan as conditions 
change, such as the number of people in the home, or if there are changes to 
the building’s construction.
 Make sure your fire warning system is operational by conducting weekly tests 
(see Here is a list of the various trouble conditions that your system 
might announce: on page 19). If you are unsure about system operation, con-
tact your installing dealer.
 We recommend that you contact your local fire department and request further 
information on fire safety and escape planning. If available, have your local fire 
prevention officer conduct an in-house fire safety inspection.

Section 8: Guidelines for
Locating Smoke Detectors
Research has shown that all hostile fires in homes gen-
erate smoke to a greater or lesser extent. Experiments 
with typical fires in homes indicate that detectable 
quantities of smoke precede detectable levels of heat in 
most cases. For these reasons, smoke alarms should be 
installed outside of each sleeping area and on each sto-
rey of the home.
The following information is for general guidance only 
and it is recommended that local fire codes and regula-
tions be consulted when locating and installing smoke 
alarms.
It is recommended that additional smoke alarms 
beyond those required for minimum protection be 
installed. Additional areas that should be protected 
include: the basement; bedrooms, especially where 
smokers sleep; dining rooms; furnace and utility rooms, 
and any hallways not protected by the required units.
On smooth ceilings, detectors may be spaced 9.1m (30 
feet) apart as a guide. Other spacing may be required 
depending on ceiling height, air movement, the pres-
ence of joists, uninsulated ceilings, etc. Consult 
National Fire Alarm Code NFPA 72, CAN/ULC-S553-
M86 or other appropriate national standards for instal-
lation recommendations. 
Do not locate smoke detectors at the top of peaked or 
gabled ceilings; the dead air space in these locations 
may prevent the unit from detecting smoke.
Avoid areas with turbulent air flow, such as near doors, 
fans or windows. Rapid air movement around the 
detector may prevent smoke from entering the unit.Do not locate the detectors in areas of high humidity.
Do not locate detectors in areas where the tempera-
ture rises above 38
oC (100oF) or falls below 5oC 
(41oF).
Smoke detectors should always be installed in accor-
dance with NFPA 72, the National Fire Alarm Code. 
Smoke detectors should always be located in accor-
dance with:
 Paragraph 2-2.1.1.1 of NFPA 72:“Smoke detectors 
shall be installed outside of each separate sleeping 
area in the immediate vicinity of the bedrooms and 
on each additional story of the family living unit, 
including basements and excluding crawl spaces 
and unfinished attics. In new construction, a 
smoke detector also shall be installed in each 
sleeping room.”
• Paragraph 2-2.1.1.2 of NFPA 72:“Split level 
arrangement. Smoke detectors are required 
where shown. Smoke detectors are optional 
where a door is not provided between living 
room and recreation room.”

Section 9: Replacing Batteries
From time to time, the batteries in the detectors and other components on your 
system will need to be changed. If a device has a low battery, your system will 
announce a “Device Low Battery” trouble message (see Checking Trouble Con-
ditions on page 19).
When the batteries in one device need to be replaced, it is suggested that the bat-
teries in all system devices be replaced at the same time. The batteries used in the 
devices are Eveready Alkaline Energizer or Energizer Lithium batteries.
NOTE: Before changing the batteries in the detectors, you should inform 
your central station.
Tips for 
Buying 
Batteries Your system is designed to work with either Eveready Alkaline Energizer or Lith-
ium batteries according to individual device. When replacing batteries, be sure 
to buy the same brand and type. Do not replace the batteries with any other 
type. The reliability of your security system depends on its batteries, and “no 
name” or generic brand batteries may not provide the best quality and 
dependability.
 Use fresh batteries. Most batteries have a “best before” date printed on their 
packaging or on the batteries themselves. Buy batteries that have a “best 
before” date of two years or more from your purchase date.
 When disposing of used batteries, follow the instructions and precautions 
printed on the batteries. Many cities and communities have collection sites or 
disposal services. Contact your municipal offices for more information.
 If in doubt about the batteries used in your system, or if you have trouble 
installing them, contact your installer for assistance.
