rise
to
the
ceiling
and
spread
horizontally.
Mounting the alarm on
the ceiling in the center
of the room places it
closest to all points
in the room. When
mounting a detector on
the ceiling, locate it at
a minimum of 4 inches
(10 cm) from the side
wall (see Figure 3). If
installing the detector on the wall, use an inside wall with
the top edge of the device at a minimum of 4 inches (10 cm)
and a maximum of 12 inches (30.5 cm) below the ceiling
(see Figure 4).
SLOPED CEILING INSTALLATION:
According to the
National Fire Protection Association (NFPA) Fire Code 72,
one should install smoke detectors on sloped, peaked or
cathedral ceilings at or within 3 feet (0.9 m) of the highest
point (measured horizontally). Do not install the Smoke/
CO detector in the peaks of vaulted ceilings, “A” frame
ceilings, or gabled roofs (see Figure 4). Smoke detectors
in rooms with ceiling slopes greater than 1 to 8 feet (0.3 to
2.4 m) horizontally should be located on the high side of the
room. A row of detectors should
be spaced and located with 3
feet (0.9m) of the peak of the
ceiling measured horizontally.
REMOVING THE BRACKET:
Remove the bracket from
the back of the Smoke/CO
detector by holding the rim
of the bracket and twisting it
counter-clockwise (to the left)
as shown here. Once removed,
proceed to install the batteries.
The Smoke/CO detector
requires three (3) AA
Energizer L91 lithium
batteries. Open the
battery covers and insert
a battery into each of the
three
compartments.
The battery polarity
markings on the cover
and inside of each
battery
compartment
must be adhered to. The
battery compartments
are fitted with a red
latch that will prevent
the detector from locking
onto the bracket if there are no batteries inside. All three
batteries must be properly installed and in good condition
for the unit to operate. Removal of any of the batteries
will render the detector inoperative. Replacement batteries
may be purchased at your local retailer. Only use the
batteries specified.
MOUNTING THE BRACKET:
The detector must be
mounted on a wall or ceiling with its bracket. It is not
designed for use as a tabletop device. Hold the bracket
against the selected installation location (wall or ceiling)
and mark the center of the holes with a pencil. Drill a hole
through each pencil mark and fasten the bracket to mounting
surface with two (2) screws. Once mounted, carefully
align the detector with the bracket and rotate it clockwise
(to the right) until the device is locked in place. Gently pull
the detector outward to verify that it is securely attached.
TESTING:
Test both sensors with the Monitoring Center
once installation is complete. Press and hold down each
test button (separately) until the built-in siren sounds and
the HELP PERS base unit begins to enunciate that an
alarm has been activated. Wait for a Life Alert Operator
to respond and confirm a successful test. Make sure to
conduct a separate test for each sensor. The Smoke/
CO detector must be tested regularly to ensure that
the batteries and alarm circuits are in good operating
condition. The test buttons for the Smoke and CO sensors
may also be used to enroll sensors.
WARNING:
The tests buttons are the only way
to properly test the smoke and CO sensors.
Never use smoke or vehicle exhaust as they may cause
permanent damage and void your warranty.
To keep your Smoke/CO detector in good working order,
please follow these simple steps. Verify alarm siren, LED
lights, and battery operation by pushing the test buttons at
least once a week. Remove the device from the mounting
bracket and vacuum the detector cover and vents with a
soft brush attachment once a month to remove dust and
dirt. Reinstall immediately after cleaning and then test
using the tests button. Never attempt to disassemble the
unit or clean inside of it as this will void your warranty.
Never use detergents or solvents to clean the unit. When
household cleaning supplies or similar contaminates are
used, the area must be well ventilated. The following
substances can damage the sensors and may cause false
readings: methane, propane, isobutene, isopropanol, ethyl
acetate, hydrogen sulfide, sulfide dioxides, alcohol base
products, paints, thinner, solvents, adhesives, hair spray,
after shave, perfume, and some cleaning agents. Do not
paint the device. Paint will seal the vents and interfere
with its ability to detect smoke and CO. Move the detector
prior to performing any of the following: staining or
stripping wood floors or furniture, painting, wall papering,
using adhesives. Store the detector in a plastic bag during
any of the above projects to help protect the sensors from

This installation instruction guide will introduce you to the
basic features, operations, and safety considerations of the
Life Alert HELP PERS combination Smoke/Carbon Monoxide
(CO) detector. Please take the time to thoroughly read
this guide and save it for future reference. The detector is
designed to automatically and independently sense both
smoke (not flame) and CO gas in an ordinary residential
environment. It provides an early warning of developing
smoke and CO events by sounding a built-in 85 decibel
alarm siren and transmitting an alarm signal to the Life Alert
Monitoring Center via the HELP PERS base unit.
CAUTION!!
This device will only indicate the presence
of smoke and CO gas at the sensor. Smoke and CO gas
may be present in other areas of the residence.
Effective pre-warning of smoke and CO events is
only possible if the detector is located, installed
and maintained as described here in this guide. If you have
any questions about this device, please contact the Life Alert
Technical Service Department at 1-800-451-7858. 16027
Ventura Blvd. Suite 400 Encino CA 91436, U.S.A
The Smoke/CO detector will operate and alert you to the
following conditions in the manner described here:
FEATURES
SMOKE ALARM:
Utilizing photoelectric technology, the
smoke sensor monitors the air for products of combustion
that are produced when something is burning or smoldering.
When smoke particles in the smoke sensor reach a specified
concentration, the alarm siren will sound. The alarm pattern
is three (3) short alarm sirens with three (3) corresponding
flashes of the red LED light. This pattern will repeat until
the smoke event is eliminated. The smoke alarm will take
precedence when both smoke and CO are present. For
increased protection, Life Alert recommends that both
ionization and photoelectric detectors be installed in the
residence.
CO ALARM:
Utilizing electrochemical technology, the CO
sensor monitors the air for the presence of carbon monoxide.
When there are high levels of CO present, or low levels of
CO present over a longer period of time, the alarm siren will
sound. The alarm pattern is four (4) long alarm sirens with
four (4) corresponding flashes of the red LED light. This
pattern will repeat until the CO event is eliminated. The CO
sensor is designed to detect carbon monoxide gas from ANY
source of combustion.
IT IS NOT DESIGNED TO DETECT
ANY OTHER GAS.
TEST BUTTONS:
To conduct a local test, push the two test
buttons at the same time to verify proper Smoke and CO
sensors operation. If both test buttons are pressed, the alarm
pattern is one (1) short alarm siren with one (1) corresponding
steady flash of the red LED light.
LOW BATTERY:
The device is powered by three (3) AA
Energizer L91 lithium batteries. When the batteries are low
and need to be replaced, the device will chirp once and the
amber LED light will flash once every fifty (50) seconds.
The pattern will repeat until the batteries are removed (and
replaced) or the batteries cease functioning.
SMOKE TROUBLE:
When there is a trouble issue with the
Smoke sensor, the device will chirp three (3) times and the
amber LED light will flash once every fifty (50) seconds.
SMOKE LOW SENSITIVITY:
When there is a low sensitivity
issue with the Smoke sensor, the device will chirp two (2)
times and the amber LED light will flash once every fifty (50)
seconds.
CO TROUBLE:
When there is a trouble issue with the
CO sensor, the device will chirp once and the amber
LED light will flash two (2) times every fifty (50) seconds.
END OF PRODUCT LIFE:
After five (5) years of cumulative
use, the device will chirp once and the amber LED light will
flash four (4) times every fifty (50) seconds. This indicates
that the device must be replaced immediately as it may not
be able to detect CO in this condition. Please call the Life Alert
Technical Service Department at 1-800-451-7858 for further
assistance.
WHERE TO INSTALL:
Before installing your Smoke/CO
detector, it is important to choose the best locations in your
home. Placement will affect how well the device performs
and how well residents hear the alarm siren if it sounds. For
maximum protection, Life Alert recommends a Smoke/CO
detector be installed on each level of a multi-level home,
including every bedroom, hallways, finished attics and
basements. Install a detector in every room where
someone sleeps with the door closed. A closed door may
prevent a detector not located in that room from waking the
occupant. For bedrooms, hallways, or large rooms greater
than 30 feet (9.1 m) in length, install detectors at both ends
of the room or hallway. For additional protection, place
additional Smoke/CO detectors between 5 and 20 feet
from potential sources of CO, such as a furnace, water
heater or fireplace.
If you only have one detector, ensure it is placed in the
hallway outside of the main sleeping area, or in the main
bedroom. Verify that the detector can be heard in all
sleeping areas.
Do not install the Smoke/CO detector in garages, kitchens,
furnace rooms, fireplaces, bathrooms, or unfinished attics.
Keep the device at least 5 feet (1.5 m) away from any
fuel-burning equipment. Keep the device at least 3 feet
(0.9 m) away from the following: a door to a kitchen or
bathroom (that contains a tub or shower), air conditioners
or forced air supply ducts used for heating or cooling,
ceiling or whole house ventilating fans, or other high air
flow areas. Keep the detector away from drapes or other
objects that may block airflow to the sensors. Do not place
the device in the direct sunlight or near doors and windows
that open up to the outside. Install the detector at least 1
foot (0.3 m) away from fluorescent lights. Do not install in
areas where the temperature is colder than 40 degrees
Fahrenheit (4.4 Celsius) or hotter than 100 degrees
Fahrenheit (37.8 Celsius) as extreme temperature will
affect the sensitivity of the Smoke/CO detector. Do not
install in areas where the relative humidity is greater than
85%. Avoid excessively dirty, dusty, or greasy areas. Dirt,
dust, grease, or household chemicals can contaminate the
device’s sensors, causing it to not operate properly. Make
sure to keep the detector away from any insect infested
areas.
