Description

The 2GIG CO3-345 is a wireless, fully supervised Carbon Monoxide (CO) detector. The detector is 3V battery powered (CR123A Panasonic battery) and outfitted with an electrochemical carbon monoxide sensor. Like any CO detector, there is a 5 year 'end-of-life' from the manufactured date. When the detector has reached the end of its life, the yellow LED blinks once every 23 seconds and there is a chirp from the keypad every 45 seconds. After 12 hours the panel will issue a trouble and display a loss of supervision message. This indicates that the CO sensor inside the detector has passed the end of its life and the detector must be replaced.

The CO3-345 has a speaker on-board that generates the ANSI S3.41 temporal 4 pattern in an alarm condition. It is extremely important to evacuate the premise if this noise is ever triggered. In normal circumstances, the green LED should flash every 12 seconds. This means that the unit is communicating with the alarm system and fully functional. In an alarm/test event, the red LED will flash every 12 seconds. When testing any CO detector, be sure to place the alarm system on test with the central station. Most central stations do not call to verify CO alarms since every second counts in a true CO alarm event! When there is a low battery, the yellow LED will flash every 12 seconds. Be proactive and replace the batteries the first time this occurs. Any trouble on the detector will produce a keypad alert and an audio chirp every 45 seconds.

This CO detector should be installed near every fuel burning appliance and there should be at least one per floor of the premise. Ideally, stay at least 5 feet away from cooking areas and areas that may result in the sensor collecting dust/dirt and compromising its CO detection. Every home and business should have a CO detector. Most building code now requires it. The benefit of a monitored CO detector is simple. Carbon Monoxide causes acute neurological effects to the brain which can cause individuals to pass out. Dispatching the fire department quickly can be the difference between life and death.

The Honeywell Lyric alarm system now supports this sensor with the release of the MR3 firmware update! The GC3 must have firmware revision 3.0.1 or higher to support the CO3.

The 2GIG CO3 is a wireless carbon monoxide sensor that operates at the 2GIG 345 MHz frequency. This makes it compatible with systems like the Honeywell Lyric, the 2GIG GC3, and the 2GIG Go!Control. For the most part, this is a well-built and reliable CO detector. But unfortunately, it has a major flaw. This sensor only has a 5-year product life. Limited product life is nothing new for a CO detector, and it is something you will likely need to consider no matter which model you end up going with. But you can usually do a little bit better than just five years. And it's a shame because this is otherwise a great sensor. Overall, we give the 2GIG CO3 a 4-Star rating.

It's not like the 2GIG CO3 doesn't have positive aspects. Like most 2GIG products, the 2GIG CO3 has a good build quality. There is an LED light on the sensor to provide a visual indication of current status. It also has a built-in sounder to alert building occupants upon detecting carbon monoxide. And it uses the recognizable Temporal 4 sounding pattern to indicate a carbon monoxide alarm. Since this is an electrochemical CO detector, it works very reliably. Another benefit is that the sensor is versatile, as it can interface with the wireless 2GIG Systems and the Honeywell Lyric Alarm System.

But there is an important flaw for the 2GIG CO3. Its 5-year end-of-life is pretty disappointing, even for a CO detector. One of the biggest downsides to any CO detector is that it will only have a limited product life. This is because the electrochemical detection component loses sensitivity over time and cannot last forever. But we normally expect this lifespan to be roughly 8 to 10 years. Just five years is really lackluster. And you will be spending more money over time on a sensor that, while extremely important for life-safety purposes, will probably never be used. And that is enough to knock our score down to 4 Stars.

Good: Great Build Quality, LED Light, Built-In Sounder, Temporal 4 Sounding Pattern, Versatile

Bad: Five Year Product Life

Bottom Line: 4 Stars

Whoever designed this product should go back to school. Did they ever tested it? I had to use a beer opener with some effort to get the battery out.
These devices have indicators within the packaging on when to replace them.
What is the date code?
No. None of the 2GIG sensors are compatible with the Lyric. We recommend swapping in a SixSmoke: https://www.alarmgrid.com/products/honeywell-sixsmoke. If you have several 2GIG sensors you may want to consider the RE524X: https://www.alarmgrid.com/products/resolution-products-re524x. This is a wireless translator that will accept 2GIG transmissions and convert them to Honeywell.
is the 2Gig CO Monitor compatible with the Lyric Controller?
The device has a 5 year life span from the date of manufacture so it does seem like they installed a unit that sat on someone's shelf for roughly 4 year. You should ask them to replace it with a newer unit. Did you notice we offer no-contract monitoring services online at https://www.alarmgrid.com/monitoring ? If you are unhappy with your current company and not under contract now, you could switch to us if you are interested.
I had one installed by a local company. Unfortunately, the expiration date was just one year into the future. Should I have received a unit with that little time left? What would be a more normal time that I should have gotten?
