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.
Model2012Hisalow-voltagephotoelectronicsmokedetectordesignedfor
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 detec-
tor 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 sig-
nalcomplieswithUL217.Thesignalconsistsof3beepseach.5seconds
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 provid-
ing 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
onlyU.L.listedtobepoweredbySystemSensorPartNo.A77-727-01(12-
volt 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.

circuit which cannot be turned off by a switch. Power supply and detec-
tor 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.
Smoke Detector Limitations
• This smoke detector is designed for residential use only. System
Sensor does not advise the use of this detector in multiple detector
systems monitored by a central control. This detector is self-restoring
and does not lock into an alarm condition.
• 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.
• Smokedetectors may not be heard. The alarm horn in this smoke
detector meets or exceeds current Underwriter’s Laboratories stan-
dards.However,ifthesmokedetectorisnotlocatedinthesameroom
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 per-
sons 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 explo-
sions, escaping gas, improper storage of flammable materials, over-
loaded 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.
• Smokedetectorsarenotasubstituteforlifeorpropertyinsurance.
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 mainte-
nance 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 preven-
tative 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.
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 addi-
tion, observe all local and national building and electrical codes.
