System Sensor i4 Series 2-wire Smoke/CO Detector
If you're looking for an aesthetically pleasing, cost effective solution to detecting smoke and carbon monoxide then the System Sensor i4 Series Smoke/CO Combination detector is what you've been looking for.
The COSMO-2W is a 2-wire smoke detector with built-in carbon monoxide detector. This is compatible with most hardwired alarm systems. You will have to use a control module. For the COSMO-2W you will use the COSMOD2W control module. The module is the interface between the detector and the panel. It allows a 2-wire or 4-wire device to communicate distinct smoke, maintenance and CO signals to the panel while reducing wiring requirements as compared to separate smoke and CO devices. The modules can handle 12 devices on a loop. In addition to that all COSMOs have a built-in sounder allowing the COSMOD module to act as a reversing relay, setting off all of the detector sounders at once.
When you run back to the main control panel from the module you will have two wires for power, two wires for the smoke zones, and 2 wires for the CO zones. The module will derive its power from your panel's auxiliary power terminals.

QUESTIONS & ANSWERS
Ask a Question-
Does this unit need to be replaced every 7-10 years or just the CO-REPL?
You can just replace the co module to further extend the unit life. See here:

When using with a Vista system is it possible to program a delay to a smoke alarm going off? As if to turn it off when you accidentally set it off with a kitchen mishap. (There’s no fire, and I don’t want to immediately have the FD called)
There is a zone type called fire verification which requires smokes to be triggered twice within a set time limit before the alarm is triggered. You'll need access to the programming to edit this.

Can I use this relay with a Honeywell VISTA-20P Ademco Control Panel, PCB in Aluminum Enclosure?
Yes, the COSMOD works well with Honeywell, but you will need a relay on the Honeywell to power the COSMOD such as the ones on the 4229 expander and the 4204 relay board.

The sounder provides an 85 dB warning tone to let those in the area know a fire emergency is occurring. The heat detector in this unit will trip if the temperature reaches 135 degrees.\u003c\/p\u003e\n\u003cp\u003eThe 2WTA-B features drift compensation to help reduce false alarms by reducing false trips due to dust and other particulates. It also uses smoothing algorithms to help cut RF interference and further reduce false alarms. The smokes operate on either the 12V or 24V power structure.
