Introduction

Electronics Line Ltd.'s Wireless Carbon Monoxide Detector (CO) is an
effective device for detecting the buildup of Carbon Monoxide. Upon
detecting the CO gas, the unit emits an alarm and notifies the control panel.
The main features of your CO gas detector include the following:

 Integrated transmitter designed for use with EL's wireless alarm

systems

 Easy to install
 Monitoring of carbon monoxide in a continuous manner.
 Loud alarm (85 dB) when detecting a buildup of carbon monoxide
 Test button
 Continuous Self-testing function

What You Should Know About Carbon Monoxide

Carbon monoxide, also known as "CO" by the chemical form, is
considered to be a highly dangerous poisonous gas, because it is
colorless, odorless, tasteless and very toxic. In general, biochemistry
phenomena have shown that the presence of CO gas inhibits the blood's
capacity to transport oxygen throughout the body, which can eventually
lead to brain damage.
In any closed space (home, office, recreational vehicle or boat) even a
small accumulation of CO gas can be quite dangerous.
Although many products of combustion can cause discomfort and adverse
health effects, it is CO gas which presents the greatest threat to life.
Carbon monoxide is produced by the incomplete combustion of fuels such
as natural gas, propane, heating oil, kerosene, coal, charcoal, gasoline, or
wood. The incomplete combustion of fuel can occur in any device which
depends on burning for energy or heat such as furnaces, boilers, room
heaters, hot water heaters, stoves, grills, and in any gasoline powered
vehicle or engine (e.g. generator set, lawnmower). Tobacco smoke also
adds CO to the air you breathe.
When properly installed and maintained, your natural gas furnace and hot
water heater do not pollute your air space with CO. Natural gas is known
as a "clean burning" fuel because under correct operating conditions, the
combustion products are water vapor and carbon dioxide (CO2), which is

not toxic. The products of combustion are exhausted from furnaces and
water heaters to the outside by means of a fuel duct or chimney.
Correct operation of any burning equipment requires two key conditions:

(a) An adequate supply of air for complete combustion.
(b) Proper venting of the products of combustion from the furnace
through the chimney, vent or duct to the outside.

Typical carbon monoxide gas problems are summarized here:

(a) Equipment problems, due to defects, poor maintenance,

damaged and cracked heat exchangers

(b) Collapsed or blocked chimneys or flues, dislodged, disconnected

or damaged vents

(c) Downdraft in chimneys or flues. This can be caused by very long

or circuitous flue runs, improper location of flue exhaust or wind

conditions
(d) Improper installation or operation of equipment, chimney or vents
(e) Air tightness of house envelop/inadequate combustion of air
(f) Inadequate exhaust of space heaters or appliances
(g) Exhaust ventilation/fireplace competing for air supply

Potential sources of carbon monoxide in your home or office include
clogged chimney, wood stove, wood or gas fireplace, automobile and
garage, gas water heater, gas appliance, gas or kerosene heater, gas or
oil furnace and cigarette smoke.

Installing the Detector
Selecting the installation location

Since CO gas moves freely in
the air, the suggested location
is in or as near as possible to
sleeping areas of the home,
30 cm (12 inch) below the
ceiling . For maximum
protection, a CO detector
should be located outside the
primary sleeping areas or on
each level of your home
(see Fig 1 for suggested
locations).

IMPORTANT:

This device is not suitable for installation in a hazardous location, as
defined by the US National Electrical Code.
Do not place the detector in the following areas:
(a) Where the temperature may drop below 4C (39F) or exceed 38C

(100F).
(b) Near paint thinner fumes
(c) Within 1.5 meter (5 feet) of open flame appliances such as furnaces,

stoves and fireplaces
(d) In exhaust streams from gas engines, vents, flues or chimneys
(e) Do not place in proximity to an automobile exhaust pipe; this will

damage the detector

To install the detector:

1. Remove the mounting bracket from your unit according to Fig. 2.

Fig. 2

2. Hold the Mounting bracket against the wall as a template and mark the

locations for the 2 mounting holes.

3. Using a 5 mm (3/16-inch) drill bit, drill two holes at the marks and

insert wall plugs (Fig 3).

Fig. 3

4. Secure the mounting bracket to the wall.

5. Open the battery cover by pushing down on the battery snaps (Fig. 4).

Fig. 4

6. Insert the batteries (supplied) into the battery compartment. Pay

attention to the correct battery polarity (+) (-) and close the battery
compartment

7. Line up the side slot of the bracket and the detector. Push the detector onto

the mounting bracket until a click is heard (see arrow direction, Fig 3).

8. Pull the detector outwards to make sure that it is securely attached to

the mounting bracket.

Transmitter/Receiver Communication Setup

1. Set the panel to registration mode.

2. Insert the batteries into compartment. The detector enters

registration mode during which a transmission is sent every few

seconds. You can terminate registration mode by pressing the Test

Button. Test mode is automatically terminated after approximately

five minutes.

3. Verify that the detector has been identified by the receiver.

Testing And Resetting Your Detector

A green power light indicates that power is supplied. To test the detector,
press the Test button. The detector will beep intermittently and the three
LEDs will flash. Release the Test button. The beep and the three LEDs will
stop and the green LED remains on or flashes every 60 seconds.

Muting Your Detector

You can partially mute the detector in an event of alarm by pressing the
Test Button. The Red LED will continue to flash and a short beep will be
heard every 16 seconds.

Detector Malfunctioning

A malfunctioning unit is indicated by beep-sounding on and off
sequentially, i.e., beeping for 3 seconds with 3 seconds delay between two
beeps. If this occurs, remove the batteries from the unit for 10 seconds
and then install them again. Should the unit again beep intermittently, DO
NOT use this detector. Send the malfunctioning unit to the manufacturer
for servicing.

Taking Care Of Your Detector

You have to maintain the detector to ensure proper operation:

1. Use a vacuum cleaner to clean the air vents occasionally to keep
them free of dust.

2. Press the Test button on your detector to test its operation once
every week.

Actions to Take When Alarm Sounding

In case of harmful levels of CO gas being detected, your detector will go
into a continuous full alarm. Try to take the following necessary actions
immediately:
(a) If there is anyone experiencing the effects of carbon monoxide

poisoning such as headache, dizziness, nausea or other flu-like
symptoms, call your fire department or emergency service department
right away. You should evacuate all the people in the premises
immediately. Do a head count to check that everybody is present.

(b) Do not re-enter the premises until the problem has been corrected

and the CO gas has been dispersed out and a safe level is reached.

(c) If no symptoms exist, immediately ventilate the home by opening

windows and doors. Turn off fuel burning appliances and call a
qualified technician or your utility company to inspect and repair your
problem before restarting appliances.

WARNING: Normally an activation of the detector indicates the presence
of CO gas. However, the CO gas can be extremely fatal, if it is not
detected. The source of the CO gas may come from several possible
situations, please refer to the list of sources of carbon monoxide in page 1.
CAUTION: This detector will only indicate the presence of CO gas at the
sensor. However, you have to be aware that the CO gas may be present in
other areas in the premises.

Actions to Take After The Problem is Corrected

Once the problem of the CO gas presence in the premises has been
corrected, the detector alarm should be off. After waiting for 10 minutes,
push the Test button to test the detector, and by that, being confident that
the detector is working properly again.

Technical Information

The Carbon Monoxide Detector is engineered to be able to provide alarm
sounds based on the UL standards due to various exposure times at
different level of carbon monoxide concentrations.
According to the Underwriters Laboratories Inc. the carbon monoxide
concentrations and exposure time standards for the alarms have been
established and specified below:
A full alarm is activated under the following conditions:

- between 60 and 90 minutes at exposures of 70 ppm

- between 10 and 30 minutes at exposures of 150 ppm

- between 4 and 10 minutes at exposures of 400 ppm

WARNING AND LIMITATION

This detector may not alarm at low carbon monoxide levels. The
Occupational Safety and Health Association (OSHA) has established that
continuous exposure levels of 30 ppm should not be exceeded in an 8
hours period. Individuals with a medical problem may consider more
sensitive detection devices.
The CO gas detector is not suitable as a smoke or fire detector. This
detector is not suitable to install in a hazardous location, as defined in the
National Electrical Code.
This detector will not work without power. EL's Carbon Monoxide Detector
will not work if the batteries are removed for any reason. Additionally,
carbon monoxide must reach the detector for the proper performance of
CO gas detection.
Carbon monoxide detectors may wear out because they contain electronic
parts that fail at any time. Test your detector at least once week (see the
section "TESTING YOUR DETECTOR").
