2.3 Register the Wireless CO Detector
The wireless CO detector must be registered to function in your 
EchoStream system. Transmitters must be registered with the system in 
order to be monitored and supervised. EN1245, EN1245A and EN1245Z 
wireless CO detectors send a check-in message every three minutes; 
EN1245-60 wireless CO detectors send a check-in message every 60 
minutes.
Note: For UL 2560 installations, transmitters must have a minimum check-
in time of 60 minutes.
Refer to your receiver, network coordinator or control panel manual for 
registration instructions. Inovonics recommends all EchoStream 
transmitters be supervised. 
4. When prompted to register the device, remove and reinstall the battery 
per section 6.1, “Replace the Battery” on page 4. 
2.4 Mount the Wireless CO Detector.
 Figure 2  CO detector placement in multi-level residence
Choose a location for the wireless CO detector, paying attention to the 
following guidelines. 
Do install:
• Within 10 feet of all sleeping areas.
• On every floor of the building.
• In every room that contains a fuel-burning appliance.
Note: If the room with a fuel-burning appliance is not normally used, such 
as a boiler room, the detector should be placed just outside the room so 
that the alarm can be more easily heard.
Warning: In order to comply with FCC RF exposure requirements, a 3.94” 
(10 cm) distance must be maintained between all persons and the wireless 
CO detector.
Do not install:
• Within 10 feet of any cooking appliance.
• Directly above a sink, cooker, stove or oven.
• Next to a door or window that would be affected by drafts.
• Near an extractor fan or air vent.
• Outside.
• In any environment that does not comply with the detector’s 
environmental specifications.
• In or below a cupboard.
• Where air flow would be obstructed by curtains or furniture.
• Where dirt or dust could collect and block the sensor.
• Where the detector could be knocked, damaged, or inadvertently 
removed.
• To removable ceiling panels. Attach the detector across panel support 
as shown in Figure 3.
 Figure 3  Mount the CO detector across ceiling panel support
Caution: Airborne dust particles can enter the detector. Inovonics 
recommends removing CO detectors before beginning construction or any 
other dust-producing activity. Carbon monoxide detectors are not to be 
used with detector guards unless the combination has been evaluated and 
found suitable for that purpose.
5. Referring to figure 4, use the included mounting screws and dry wall 
anchors to mount the wireless CO detector.
6. Referring to figure 4, fit the detector inside the base by aligning it such 
that the detector’s alignment notch is slightly offset from mounting 
base’s tamper release tab.
7. Turn the detector in a clockwise direction until it clicks into place.

8. Refer to section 3, “Test the Wireless CO Detector” to test the wireless 
CO detector.
3 Test the Wireless CO Detector
There are two ways to test the wireless CO detector sensor: The system 
test and CO test. Both tests should be performed at least semi-annually per 
NFPA 720.
The wireless CO detector should also be tested after initial registration, as 
well as each time the battery is replaced.
Caution: Performing a system or a CO test will transmit an alarm signal.

Detector Tester Aerosol, within 1/4” of the gas entry ports.
3. Ensure the sounder activates, the red LED lights briefly, and the control 
panel, serial receiver or network coordinator receives an alarm, 
followed a few seconds later by a restoral.
4 Operation
4.1 Carbon Monoxide Gas and Detection
This CO detector is designed for indoor use only. Do not expose it to rain or 
moisture. Do not drop the detector or subject it to other physical shock. Do 
not open or tamper with the detector as this may cause it to malfunction. 
The detector will not protect against the risk of carbon monoxide poisoning 
if not properly installed.
Note: The detector will only indicate the presence of carbon monoxide gas 
in the vicinity of the detector itself. Carbon monoxide gas may be present in 
other areas.
This CO detector is not:
Designed to detect smoke, fire or any gas other than carbon monoxide
• 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 burned. It is invisible, has no smell and is therefore 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 such appliances 
should not be dangerous.
4.2 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 
related to carbon monoxide poisoning and should be discussed with all 
people in the facility:
• Mild exposure: Slight headache, nausea, vomiting, fatigue (often 
described as flu-like symptoms).
• Medium exposure: Sever throbbing headache, drowsiness, confusion, 
fast heart rate.
• Extreme exposure: Unconsciousness, convulsions, cardio respiratory 
failure, death.
Many causes of reported carbon monoxide poisoning indicate that while 
victims are aware that they are not well, they become so disoriented that 
they are unable to save themselves by either exiting the building or calling 
for assistance.
Also, young children and pets may be the first to be affected.
4.3 Alarm Thresholds
Alarm thresholds are as follows:
4.4 In the Case of an Alarm
Actuation of your CO alarm indicates the presence of carbon monoxide 
(CO), which can cause injury or death.
Individuals with medical problems may consider using warning devices 
which provide audible and visual signals for carbon monoxide 
concentrations under 350ppm.
What to do if the carbon monoxide detector goes into alarm:
1. Push the test button. If the detector reactivates or the detector does not 
silence, continue with step 2.
2. Immediately move to fresh air, outdoors or by an open window. Check 
that all persons are accounted for. 
3. Call your local fire department from a phone in an area where the air is 
safe. Do not reenter the premises nor move away from the open door/
window until emergency service responders have arrived.
4. If your detector reactivates within a 24-hour period, repeat steps 1 
through 3 and call a qualified appliance technician to investigate 
possible sources of CO from fuel burning equipment and appliances, 
and check for proper operation of this equipment. If problems are 
identified during this inspection, have the equipment serviced 
immediately. Note any combustion equipment not inspected by the 
technician and consult the manufacturer’s instructions, or contact the 
manufacturers directly, for more information about CO safety and this 
equipment. Make sure that motor vehicles are not, and have not been, 
operating in an attached garage or adjacent to the residence.
Caution: This detector should be tested and maintained regularly following 
National Fire Protection Association (NFPA) 720 requirements. This 
detector should be fully tested at least once per month.
4.5 CO Technology Limitations
The EN1245 uses an electrochemical CO sensing element, and therefore 
has certain performance limitations. The CO sensing element has a typical 
life of ten years from the date of manufacture, and while the product has a 
timer to create a trouble condition after ten years of operating, the date 
code of the product, rather than the timer, should determine when the 
product is replaced.
The CO sensing element has a carbon filter that provides resistance to 
false alarms caused by cross-interference gasses, but the filter can be 
saturated, and so the product should not be installed in locations where 
high concentrations of these gasses are present. Cross-interference 
gasses include, but are not limited to: Methane, Butane, Heptane, Ethyl 
Acetate, Isopropyl Alcohol, Carbon Dioxide, Ammonia, Ethanol, Toluene, 
Trichloroethane, and Acetone. Only a cloth moistened with water should be 
used to clean the EN1245 housing.
The movement of gases into the sensing element can be impaired if a 
sealant blocks the porous surface of the CO sensor. The EN1245 should 
not be exposed to aerosol products such as furniture polish, paint or 
varnish that can coat the CO sensing element and render it inoperative.
5 Maintenance
Occasionally clean the outside casing with a clean water-moistened cloth. 
Ensure that the holes on the front of the alarm are not blocked with dirt and 
dust. Do not paint, and do not use cleaning agents, bleach, or polish on the 
detector.

6 Detector Replacement
This detector is manufactured with a long-life carbon monoxide sensor. 
Over time the sensor will lose sensitivity, and will need to be replaced with 
a new carbon monoxide detector. This detector’s lifespan is approximately 
ten years from the date of manufacture. The user should periodically check 
the detector’s replacement date. Remove the detector from its base and 
check the replacement date label on the underside of the detector. The 
label indicates the date that the detector should be replaced.
Note: When the detector is removed from its base, a message is sent to 
the central station. If the system is armed, a tamper alarm message is sent; 
if disarmed, a trouble message is sent. The detector will also indicate a 
trouble condition when it has reached the end of its useful life. If this 
occurs, it is time to replace the detector.
Note: Before replacing the detector, notify your 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. Dispose of detector in accordance with any local 
regulations.
Caution: It should be noted that installation, operation, testing and 
maintenance of the CO detector is different than smoke detectors. Per 
NFPA 720 section 5.3.7.2 the detector shall not be connected to a zone 
that signals a fire condition (i.e. smoke detector zones). Therefore, the CO 
detector must be programmed as a non-fire zone. See the control panel’s 
Installation Instructions for the appropriate carbon monoxide zone type to 
be programmed.
6.1 Replace the Battery
Caution: Never install a used or depleted battery, as this can result in 
unreliable operation. Only install new batteries.
To replace the battery:
1. Twist the wireless CO detector counterclockwise and remove it from the 
mountain base. 
2. Remove the battery, properly disposing of it.
3. To ensure the proper power-down sequence, wait at least 20 seconds 
before installing the new battery.
4. Following the polarity diagram inside the battery compartment, install 
the new 3-volt CR123A lithium battery. 
5. Reinstall the detector onto the mounting base, and turn it clockwise to 
lock it into place.
6. Ensure the green LED is blinking about once every 10 seconds to 
indicate normal operation.
7. Test the CO detector as described in section 3, “Test the Wireless CO 
Detector”.
