2012H Photoelectronic Smoke Detector with

INSTALLATION AND MAINTENANCE INSTRUCTIONS
2012H Photoelectronic Smoke Detector
with Integral Temp-3 Sounder
• Smoke detectors will not sense a fire if the smoke does not reach
the sensor. In order for a smoke detector to sense smoke, it must be
installed in the immediate vicinity of the fire. In addition, smoke from
fires in chimneys, in walls, on roofs, in remote parts of the building,
or on another level from where the smoke detector is located, may
not reach the smoke detector quickly enough for occupants to escape
unharmed. For this reason, the installer shall install smoke detectors
on every level, in every sleeping area, and in every bedroom of the
household.
• Smoke detectors may not be heard. The alarm horn in this smoke
detector meets or exceeds current Underwriter’s Laboratories standards. However, if the smoke detector is not located in the same room
as the occupant, or if it is blocked by a closed door or normal noise,
the alarm horn may not be heard. In addition, sound sleepers, or persons who are under the influence of drugs or alcohol may not hear the
alarm or be able to react to it. Therefore, locate this smoke detector,
which has a sounder rated at 85 dB at 10 feet, on every level, in
every sleeping area, and in every bedroom of the household.
• In general, detectors may not always warn you about fires caused
by carelessness and safety hazards like smoking in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing with matches, or arson.
• Smoke detectors are not fool-proof. Like all electronic devices,
smoke detectors have limitations. No type of smoke detector can
sense every kind of fire every time. In addition, smoke from slow,
smoldering fires rises slowly and may not reach the smoke detector
until actual flame breaks out. This type of smoke may not reach the
smoke detector in time for occupants to escape unharmed.
• Smoke detectors are not a substitute for life or property insurance.
Though smoke detectors have been responsible for saving many lives,
they are not warranted or implied to protect lives or property in the
event of a fire.
• To keep your equipment in excellent working order, ongoing maintenance is required per the manufacturer’s recommendations and UL
and NFPA standards. At a minimum, the requirements of Chapter 7 of
NFPA 72, the National Fire Alarm Code, shall be followed. A preventative maintenance agreement should be arranged through the local
manufacturer’s representative. Though smoke detectors are designed
for long life, they may fail at any time. Therefore, smoke detectors shall
be replaced after being in service for 10 years. Any smoke detector, fire
alarm equipment, or any component of that system which fails shall
be repaired or replaced as soon as possible.
Smoke Detector Description
Smoke detectors are designed to provide early warning of developing fires
at a reasonable cost. They monitor the air and can sense smoke, providing
precious minutes for you and your family to escape before a fire spreads.
Early warning fire detection is best achieved by the installation of fire
detection equipment in all rooms and areas of the household.
Model 2012H is a low-voltage photoelectronic smoke detector designed for
open area protection in a residential building. It has a built-in relay which
may be used to activate auxiliary devices such as bells, horns, and door
closers. The relay contacts automatically close 8 seconds after the detector goes into alarm, and automatically resets approximately 5 seconds
after the alarm stops. A piezoelectric horn in each detector produces an
audible 85 dBA temporal tone evacuation signal when a detector alarms
or an interconnected detector alarms. This temporal tone evacuation signal complies with UL217. The signal consists of 3 beeps each .5 seconds
long, spaced .5 seconds apart, followed by 1.5 seconds of silence. These
detectors can be interconnected for a system of up to 12 smoke detectors
per household so when one smoke detector sounds its evacuation signal
it causes the other connected detectors to sound as well.
Installation in Australia Only
The installation temperature range for Australia is 5° to 45°C and has
been tested per the Australian Standard. Ignore installation temperatures
specified for all other applications when installing detectors in Australia.
Detectors should be installed by qualified technicians. Installation of
a main connected power supply unit must be performed by qualified
electricians only. Ignore the power requirements in “Smoke Detector
Requirements” listed below, as these apply to installation in the USA.
The primary power should be provided by a power limited, supervised,
panel type system. A rechargeable battery is required as a backup to the
external power supply in case of a mains failure. In standby operation, the
power limited backup battery (fully charged) must be capable of providing uninterrupted power for at least 7 days to the system and all smoke
alarms before the panel gives the required low-battery signal. When the
low-battery signal is given, the battery should be capable of providing
power for another 7 days, after which the backup battery should have
enough energy left to allow a 4-minute alarm signal to be given by all
connected smoke alarms.
Smoke Detector Power Requirements (USA)
This smoke detector will not work without power. This smoke detector is
only U.L. listed to be powered by System Sensor Part No. A77-727-01 (12volt DC power supply). The A77-727-01 must be permanently connected
to the building’s 120-volt AC electrical supply per code. The A77-727-01
will not power the smoke detector if the AC power is cut off for any
reason. The 12-volt DC power supply will only power the detector when
120-volt AC power is present—it is not a power back-up source.
Where to Install Smoke Detectors
Warning: As a minimum requirement, smoke detectors must be installed
in accordance with the National Fire Protection Agency (NFPA) Standard
72 which defines the standards for the National Fire Alarm Code (National
Fire Protection Association, Battery march Park, MA 02269-9101). In addition, observe all local and national building and electrical codes.
Proper Detector Location:
Figure 1: Recommended smoke detector protection for singlefloor residence with only one sleeping area
Power input rating to the detector is 12VDC @ 0.02 amps. Input power
to the A77-727-01 power supply must be from a 24-hour 120V AC 60HZ
circuit which cannot be turned off by a switch. Power supply and detector installation must conform to the electrical codes in your area and
Article 760 of the National Electrical Code. It is recommended that
wiring be performed by a licensed electrician.

NFPA 72, Chapter 2, Section 2-2.1.1.1 states as follows: “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.”
The above NFPA standard is a minimum requirement for smoke detector
installation. For better protection, we also require the installation of a
smoke detector inside every bedroom in existing construction.
• Install a minimum of two smoke detectors in any household, no matter
how small it is.
• Put a smoke detector in the hallway outside of every separate bedroom area. (See Figure 1.) A minimum of two detectors are required
in homes with two bedroom areas. (See Figure 2.)
• Put a smoke detector on every level of a multi-level residence. (See
Figure 3.)
• Install basement detectors on the ceiling at the bottom of the basement
stairwell. (See Figure 3.)

Where Smoke Detectors Should NOT Be Installed
• In or near areas where combustion particles are normally present
such as kitchens; in garages where there are particles of combustion in vehicle exhausts; near furnaces, hot water heaters, or gas
space heaters. Install detectors at least 20 feet (6 meters) away from
kitchens and other areas where combustion particles are normally
present.
• On the ceiling in rooms next to kitchens where there is no transom
between the kitchen and these rooms. Instead, install the smoke detector on an inside wall, furthest from the kitchen (See Figure 6). Be sure
not to install smoke detectors within 4″ of the ceiling or any corner or
more than 6” from the ceiling.

• Install detectors on the ceiling as close to the center of the room as
possible. If this is not practical, install it on the ceiling no closer than
4 inches (10 cm) from any wall or corner. (See Figure 4.)
• If wall-mounting is permitted by local and state codes, and ceiling
mounting is not practical, install detectors on an inside wall between
4 and 6 inches (10 and 15 cm) from the ceiling. (See Figure 4.)
Figure 4: Recommended smoke detector mounting locations:
• In damp or very humid areas, or next to bathrooms with showers.
The moisture in humid air can enter the sensing chamber as water
vapor, then cool and condense into droplets that cause a nuisance
alarm. Install detectors at least 5 feet (1.5 meters) away from bathrooms.
• In very cold or very hot rooms or areas. Operating temperature of the
smoke detector is 40°F to 100°F (4°C to 38°C).
• In dusty, dirty, or insect-infested areas. Dust and dirt can build up
on the detector’s sensing chamber and make it overly sensitive, or can
block openings to the sensing chamber and keep the detector from
sensing smoke.
• Near fresh air inlets or returns or excessively drafty areas. Air
conditioners, heaters, fans, and fresh air intakes and returns can drive
smoke away from smoke detectors, making the detectors less effective.
• In dead air spaces at the top of a peaked ceiling or wall/ceiling intersect. Dead air may prevent smoke from reaching a detector.
• Near fluorescent light fixtures. Install detectors at least 10 feet (3
meters) away from such light fixtures.
Installation Requirements
Warning: Electrical Shock Hazard. Turn off power at the main fuse box
or circuit breaker to the area of detector installation before beginning
installation procedures.
• Mount detector to a 4-inch octagonal junction box only. Mount the 12
Volt D.C. power supply to a 4″ square junction box 2-1/8″ deep only.

Rotate until the arrow and nib line up. (See Figure 8).
13.After installing all detectors, turn on power at the main service
panel.
14.Check for the green LED to flash about once every 30 to 40 seconds.
This means the detector is receiving power. Check all detectors.
NOTE: If the LED does not flash, power is not getting to the smoke detector. Check wiring. If LED still does not flash, return the smoke
detector to the manufacturer for repair.
15. Test each detector in the system. (See “Testing” below for more detailed instructions.)

The built-in test switch accurately tests all detector functions, as required
by Underwriter’s Laboratories.
• DANGER: If the alarm horn sounds an alarm and you are not testing
the detector, the detector has sensed smoke or combustion particles
in the air. The alarm horn is a warning of a possibly serious situation. It requires your immediate attention. See
“What to Do In Case of Fire” section of this manual.
• The alarm could be caused by a nuisance situation. Cooking smoke or
a dusty furnace can cause the alarm to sound. If this happens, open
a window or fan the air to remove the smoke or dust. The alarm will
turn itself off as soon as the air is completely clear. Do not turn
off power to the smoke detector. This will remove
your protection.

Connecting Auxiliary Devices with Relay
This detector has a built-in relay which may be used to activate auxiliary
devices such as bells, horns, and door closers. The relay contacts automatically close approximately eight (8) seconds after the detector goes
into alarm, and automatically resets approximately five (5) seconds after
the alarm stops. For wiring refer to Figure 8. Auxiliary voltage and current
requirements must be within relay contact ratings and appropriate wiring
must be used.
Monitoring Your Detector
Once the detector is powered, a green LED flashes about 1 to 2 times per
minute. This signals that the detector is receiving power and is in the
detect mode. If the detector is not operating properly, the green LED will
be OFF. (If so, have the detector repaired or replaced immediately.) When
the smoke detector senses smoke, the green LED will flash rapidly. If the
initiating smoke detector senses smoke and signals other interconnected
smoke detectors to sound their alarms, their LED’s will stop flashing. See
chart below for specific LED functions.
Table 1: Detector Status
How to Interconnect Detectors
NOTE: Interconnect smoke detectors within one household only. If
detectors are interconnected between households, nuisance alarms
will occur when a detector in another residence is tested.
• Up to twelve 2012H, 1012, 2012, and 2001LVRI detectors may be interconnected so that if one detector senses smoke, all of them will sound
an alarm. After interconnecting the detectors, push the test switch
on one detector. The alarm horns on all of the other detectors should
sound if they are connected correctly.
• Connect the detectors together by connecting all the signal terminals
to each other and all ground terminals to each other. (See Figure 7.)
Use 18 guage (#18AWG) or larger two-conductor stranded wire.
• If detectors will not be interconnected, DO NOT use signal and ground
terminals.
• The LEDs on all smoke detectors should flash about 1 to 2 times per
minute when power is turned on to the detectors. Test detectors after
interconnection wiring is complete.
Cautionary Note: Test interconnection wiring after installation is completed. Test each unit in a system and make sure ALL
other units alarm. Failure to observe any of
these conditions can cause system malfunction and/or damage to the detectors.

Cleaning and Maintenance
DANGER: Electrical Shock Hazard. Turn off power to the smoke detector
at the main service panel before cleaning the smoke detector.
This smoke detector has been designed to be as maintenance-free as
possible. However, regular testing (see “Testing” above) and periodic
maintenance are necessary.
To clean the detector, turn off power and vacuum the outside of the detector with the soft brush attachment of a vacuum cleaner. Do this at least
once every year, preferably every six months. Do not attempt to
clean the detector in any other way.
Testing Information
• You should test your detector at least once a week to assure yourself of its operation, as recommended by NFPA. Test the detector by
firmly depressing the recessed test switch located on the detector cover
(marked “Push to Test”) with a 0.1 inch diameter tool such as an allen
wrench or small screwdriver FOR 20 SECONDS. (See Figure 9). The
alarm horn should sound, and the LED should flash rapidly.
• In an interconnected system, all of the detectors should sound their
alarm horns when any one of the test buttons is pushed. The alarm
horn sounds if the detector is working properly. This is the only way
to be sure the detector is working. Test the detector weekly. If the
detector fails to test properly, have it repaired or replaced immediately.
WARNING: Never use an open flame of any kind to test the smoke detector. You may set fire to and damage the detector, as well as your home.
If the detector requires service, do not attempt to service it yourself; this
will void your warranty. Send the detector to: Repair Department, System
Sensor, 3825 Ohio Avenue, St. Charles, Illinois 60174. Enclose a note
describing what is wrong with the detector.
