Nighthawk KN-COEG-3 - Manual (Page 4)

Quick Set-Up Guide
Step 1
Determine the best location for your CO and Gas alarm(s).
Refer to page 1-3 for complete information.
Step 2
Your CO and Gas alarm is equipped to be mounted as a cord-
ed unit (recommended for natural gas detection), a direct
plug unit (recommended for propane gas detection) or a
table top unit. In the “as shipped” configuration, the unit can
be plugged directly into a wall socket. (If your outlets are
mounted horizontally, please refer to page 1-4). If the trans-
former/adapter is taken out of the unit, the unit can be
mounted high on the wall, while the transformer is plugged
into a wall socket. The explosive Gas you use will determine
if the unit should be mounted high on the wall (cord option)
or low on the wall (direct plug option). Refer to page 1-4 for
further information on installing your alarm.
Step 3
A 9V battery is needed for backup in the event of a power
outage. When installing the battery, use an Energizer 522,
Duracell MX 1604 or, for extended life, use an Ultralife lithi-
um power cell model U9VL. Any of these batteries can be
purchased where you bought the alarm or at your local hard-
ware store. To install the battery, open the back door and
snap battery connector onto battery. You will hear the alarm
sound briefly to indicate the unit is receiving power. Place
battery into battery compartment and replace back door
(refer to page 1-1).
Step 4
First install the 9V battery then plug the alarm into a standard,
unswitched 120 volt AC electric outlet in one of the configu-
rations listed in step 2.
Step 5
At power up, you will see a flashing red dot and three eights
in the digital display indicating the alarm is warming
up. After approximately 20 seconds the unit will start sam-
pling for CO. After approximately 2 minutes the unit will start
sampling for gas. During this period a number will appear on
the digital display. The number on the digital display should
be zero (0). If not, see page 1-5 for complete information on
normal operating characteristics.
Step 6
Wait 2 to 3 minutes after power up and make sure the red dot
in the digital display is blinking. Then test the unit’s operation
by pressing and releasing the Test/Reset button. Within 15
seconds you hear 3 slow beeps with “GAS” appearing in the
digital display. Then, you will hear 4 quick beeps followed by
5 seconds of silence then 4 quick beeps repeating while a
number (usually around 200) is displayed. In normal opera-
tion, the repeating slow beeps with “GAS” showing in the dis-
play is the alarm condition notifying you that either natural
Gas or propane is being detected. The 4 quick beeps 5 sec-
onds of silence -repeating while a number is shown in the
digital display indicates that the alarm is in a condition noti-
fying you that carbon monoxide is being detected. For com-
plete testing information, refer to page 1-5.
Step 7
While testing the alarm, have someone else check that the
alarm can be heard easily from the sleeping areas. The unit
should be located where it can wake you if it alarms at night.
See page 1-3 for complete information on the best locations
for your alarm.
Caution: Continuous exposure to the loud 85 decibel alarm
at close range over an extended period of time may cause
hearing loss. We recommend that you cover the sound holes
while testing.
That’s it. Your Nighthawk CO and Gas alarm is now moni-
toring for the presence of carbon monoxide and explosive
Gas.
