This lights up when the alarm sounds. It is nor-  
mal for this light to turn on when you press the  
Test button.  
The natural gas concentrations standard for  
the alarms has been set by the Underwriters  
Laboratories Inc. to be less than 25% of the  
LEL. Therefore your unit will alarm immediate-  
ly upon detection of dagnerous levels.  
To install the detector:  
1. At the place where you are going to  
install the detector, draw a horizontal line four  
inches long.  
2. Place the circular mounting plate so that the  
square holes are aligned on the line.  
3. In each of the circular slots. Draw a mark to  
locate a mounting plug and screw.  
Yellow (Malfunction) light:  
This lights up when a detector finds a malfunc-  
tion while it is checking itself. It is normal for  
this light to turn on once or twice after you  
power the detector or after a power failure.

4. Remove the mounting plate.  
Do a head count to check  
that everybody is accounted  
for. Call the nearest fire  
department and ask them to  
determine the source of nat-  
ural gas. Do not re-enter the  
premises until the problem  
has been corrected and the  
natural gas has been dis-  
persed.  
5. Using the appropriate size drill, drill two  
holes at the marks and insert wall plugs.  
6. Using the two screws and wall plugs  
(all supplied), attach the mounting plate to the  
wall ensuring that the cord slot in the mounting  
plate is down.

The NG401, NG401A, NG405, NG405A  
Natural Gas Detector is an effective product  
for detecting any buildup of natural gas in your  
home. Dicon Global Inc., the maker of these  
natural gas detectors, has been developing  
and making products for detecting gases since  
1985.

Wait for ten minutes before you test the detec-  
tor. During that time, the alarm may sound  
several times and the yellow (malfunction)  
lights may light up once or twice as the detec-  
tor cleans the sensor. This will also occur if the  
power to the detector is interrupted.

Your new detector:  
Is easy to install  
Dicon Global Inc. warrants its enclosed Natural  
Gas Detector sensor to be free from defects in  
material and workmanship under normal use  
and service for a period of five (5) years form  
date of purchase. Dicon Global Inc. warrants  
it's enclosed Natural Gas Detector other than  
the sensor to be free from defects in materials  
and workmanship under normal use and serv-  
ice for a period of one (1) year from date of  
purchase. Dicon Global Inc. makes no other  
express warranty for this Natural Gas Detector.  
No agent, representative, dealer or employee  
of the company has the authority to increase  
or alter the obligations or limitations of this  
Warranty. The company's obligation of this  
warranty shall be limited to the repair or  
replacement of any part of the detector which  
is found to be defective in materials or work-  
manship under normal use of service during  
the first year period commencing with the date  
of purchase except for the sensor which is  
warranted during the five year period com-  
mencing with the date of purchase. During the  
latter four (4) years of the warranty period,  
such repairs or replacements other than the

sensing unit commencing with the date of pur-  
chase. In no case shall the Company be liable  
for any consequential or incidental damages  
for breach of this or any other warranty  
D. How can you test the detector?  
Monitors for natural gas continuously and  
sounds a loud (85db) alarm when it  
detects a build-up of natural gas.  
Has a Test button so that you can test it  
at any time.  
WARNING: Activation of  
this device indicates the  
presence of natural gas,  
which is flammable and can  
be fatal. The source of the  
gas may be an object such  
as a furnace, a hot water  
heater or other natural gas  
appliance.  
To test the detector, wait at least ten minutes  
after installing it, press the test button. The  
alarm sounds.  
Tests itself continuously.  
Is listed by the Underwriters Laboratories  
to UL1484 standard.  
To reset the alarm, turn the 12 Volt supply off,  
wait ten seconds, then turn it on again.  
7. Slide the detector onto the mounting plate  
so that the two arms on the mounting plate fit  
into two slots in the back of the detector.  
Has a 5-year guarantee for the natural  
gas sensing element.  
The detector continually checks itself. If it finds  
a malfunction, it lights the yellow light. If this  
occurs, call Dicon Global Inc. at 1-800-387-  
4219.  
A. Why should you be concerned  
about natural gas?  
N
GAS  
DEATTEUCRTOALR  
This detector will only indi-  
cate the presence of natural  
gas near the detector.  
Natural gas may be present  
in other areas. Correction of  
the problem may require the  
services of a local natural  
gas utility company or con-  
tractor.  
E. How can you maintain your  
detector?  
The harmful element in natural gas is  
methane, a colorless, odorless, and flammable  
gas. As natural gas builds up, it mixes with  
oxygen to produce a mixture that can be  
explosive if ignited by a spark or flame.  
A detector is only useful if it works. To keep it  
working, all you need to do is:  
vacuum the air vents occasionally to keep  
them free of dust.  
test the detector by pressing the test button  
once a month.

8. Ensure that the detector's 12 Volt wires  
are located in the cord slot or behind the  
detector in an appropriately recessed area.  
Most likely sources of leaks are gas appli-  
ances, heaters, stoves, refrigerators, and fur-  
naces. Gas leaks from outside or below  
groundlevel can also seep into your home.  
F. What do the lights mean?  
B. Where should you install the  
detector?  
The detector has three lights:  
Green (Power) light:  
This lights up when the detector has power. It  
is normal for this light to be on while the detec-  
tor is powered.  
H. What do you do after the prob-  
lem has been corrected?  
Natural gas is lighter than air and therefore  
collects in the highest areas of rooms and  
homes. To detect a dangerous concentration  
of natural gas, you should place your detector  
near a natural gas appliance or in a room  
above the appliance. For example a natural  
gas leak in the kitchen can create a build up in  
the floors above.  
On re-entering the premises after an alarm:  
1. Turn the 12 Volt supply off for ten seconds,  
and then turn it on again.  
2. After ten minutes (during which the alarm  
may sound once or twice and the yellow  
light may flash), test the detector to make  
sure that the detector is working properly.
