LED INDICATORS 
The SiXCOMBO has a multi-color top LED:  
Green = Supervisory indication; blinks during power on, reset, 
and during normal operation 
Amber = Signal maintenance and trouble events 
Red = Alarm condition (either Smoke or CO) 
Side LED windows indicate alarms:  
red = smoke 
blue = CO 
 
CLEANING 
NOTE: Notify the proper authorities when the system will be 
temporarily out of service. 
IMPORTANT: This detector must be tested and maintained 
regularly following NFPA-72 requirements.  The detector should 
be cleaned at least once a year. 
1.  Remove the detector from the base plate by turning 
counterclockwise. 
2.  Clean the outside casing with a cloth. Ensure that the holes 
on the front of the alarm are not blocked with dirt and dust. 
Canned air can be used to remove any dust or debris. 
3.  Reattach the detector to the base plate by rotating 
clockwise.  
4.  Test the detector to insure it is fully functional. (See Testing 
section). 
5.  Notify the proper authorities and Central Station when the 
system is back in service

CAUTION:  The batteries used in this device may present a fire 
or chemical burn hazard if mistreated.  Do not recharge, 
disassemble, heat above 100°C (212°F) or dispose of in fire.  
Use only Panasonic CR123A Lithium batteries. Use of other 
batteries may present a risk of fire or explosion. Keep used 
batteries away from children.  Dispose of used batteries 
properly. 
 
Remove old batteries.  Wait 10 seconds and then replace with 
four new batteries. To avoid a low battery indication when 
installing new batteries, all 4 batteries must be installed within 
15 seconds of installing the first one. Any low battery condition 
that may have occurred should clear when the base plate is 
installed.  
 
NOTE: Constant exposure to high or low temperature or high 
humidity may reduce battery life. 
 
LIMITED LIFE OF CO SENSOR
 
This detector is manufactured with a long-life electrochemical 
carbon monoxide sensor. Over time the sensor will lose 
sensitivity and will need to be replaced. The life span of the CO 
sensor is approximately ten years from the date of manufacture. 
Periodically check the detector’s replacement date. Remove the 
detector head and refer to the ‘replace by’ sticker placed on the 
underneath side of the detector. The sticker will indicate the 
date the detector should be replaced. 
Reminder: This detector is also equipped with a feature that will 
signal the panel once the CO sensor has passed the end of its’ 
useful life. If this occurs, it is time to replace the detector. 
What to do if the detector goes into CO alarm: 
If the detector goes into CO alarm (4 beeps), immediately 
move to a spot where fresh air is available, preferably 
outdoors, where the air is safe and call your security service 
provider.  Tell your provider the detector alarm status, and that 
you require professional assistance in ridding your home of the 
carbon monoxide.   
This detector is NOT: 
•   A substitute for the proper servicing of fuel-burning 
appliances or the sweeping of chimneys. 
•   To be used on an intermittent basis or as a portable alarm 
for the spillage of combustion products from fuel-burning 
appliances or chimneys. 
Carbon monoxide gas is a highly poisonous gas which is 
released when fuels are burnt. It is invisible, has no smell and 
is therefore is impossible to detect with the human senses. 
Under normal conditions in a room where fuel burning 
appliances are well maintained and correctly ventilated, the  
amount of carbon monoxide released into the room by 
appliances should not be dangerous. 
 
 
CAUTIONS:  
•  This device will only indicate the presence of carbon 
monoxide gas at the sensor. Carbon monoxide gas may be 
present in other areas. 
•  This device is designed to protect individuals from the acute 
effects of carbon monoxide exposure. It will not fully 
safeguard individuals with specific medical conditions. If in 
doubt consult a medical practitioner. 
•  Installation of the device should not be used as a substitute 
for proper installation, use, and maintenance of fuel-burning 
appliances, including appropriate ventilation and exhaust 
systems. 
 
MAINTENANCE 
Do not paint, and do not use cleaning agents, bleach or 
polish the detector. 
NOTE: Before performing any maintenance on the detector, notify the 
proper authorities and Central Station that maintenance is being 
performed and the system will be temporarily out of service. Disable 
the zone or system undergoing maintenance to prevent any unwanted 
alarms. Power must be removed from the detector before performing 
maintenance of any kind. 
 
The SiXCOMBO detector reports maintenance issues to the 
control panel and communicates them visually and audibly per 
Table 2. 
Trouble feature: When the sensor (supervision) is in a trouble 
condition (such as a detector that is dirty or CO sensor non-
functioning), the detector will send a trouble signal to the 
control panel. Depending on the issue, the detector must then 
be serviced or replaced. 
NOTE: Smoke detectors are not to be used with detector 
guards unless the combination is evaluated and found suitable 
for that purpose. 
 
SYMPTOMS OF CARBON MONOXIDE POISONING 
Carbon monoxide bonds to the hemoglobin in the blood and 
reduces the amount of oxygen being circulated in the body. 
The following symptoms are examples taken from NFPA 720; 
they represent approximate values for healthy adults. 
 
Concentration 
(ppm CO)  Symptoms 
200  Mild Headache after 2-3 hours of exposure 
400  Headache and nausea after 1-2 hours of exposure 
800 
Headache, nausea, and dizziness after 45 minutes 
of expo- sure; collapse and unconsciousness after 2 
hours of exposure 
Many cases of reported carbon monoxide poisoning indicate 
that while victims are aware that they do not feel well, they 
become so disoriented that they are unable to save 
themselves by either exiting the building or calling for 
assistance. Also young children, elderly and pets may be the 
first to be affected.
