i4 Interface Module

Average rating:

(based upon one review)

The System Sensor COSMOD2W is an interface module that is required when using a COSMO-2W 2-Wire Smoke and Carbon Monoxide Detector. Up to 12 COSMO-2W Sensors can be paired with the COSMOD2W, and they will all occupy the same two zones. Buy the COSMOD2W i4 Interface Module from Alarm Grid.

Description

The System Sensor COSMOD2W is the required interface module for use with the System Sensor COSMO-2W 2-Wire Carbon Monoxide and Smoke Detector. This set up will also require a relay and end-of-line power supervision. Up to 12 of the COSMOD2W Sensors can be used with the COSMOD2W Module.

The main purpose of the module is to allow a single hardwired COSMO-2W devices to program in two separate zones. One zone is used for fire, and the other is used for CO detection. By wiring multiple COSMO-2W devices to the COSMOD2W, you can use the additional sensors on the same two zones. The COSMOD2W displays the current status for all the connected sensors in the form of LED lights.

The System Sensor COSMOD2W i4 Interface Module is the required hub used with System Sensor COSMO-2W Hardwired Combination Smoke and CO Detectors. Even though these are 2-wire devices, they are not used with a designated "reset zone" on a wired panel. Instead, these are configured with a standard hardwired zone, similarly to how a 4-wire smoke detector would be set up. The difference here is that this interface module is absolutely required. And the interface module is known for being extremely difficult and tedious to set up and configure. On top of that, you must also add a reset relay and a CO trigger relay for this set up to work. But on the positive side, the System Sensor COSMO devices are the only wired combination smoke and CO detectors used directly with security systems that we know about. And also, they offer one-go-all-go, which is a fantastic life-safety feature. Still, we don't recommend using these devices simply because they are very complicated for a DIY user to set up, and there are better options readily available. For that reason, we only give the System Sensor COSMOD2W i4 Interface Module a 2-Star rating.

There are some positive aspects regarding the System Sensor COSMOD2W i4 Interface Module. It allows the use of a combined smoke detector and CO detector into one device. The sensor can be used with any hardwired zone, which adds some nice versatility. We also really appreciate the fact that this sensor supports one-go-all-go. When we discuss one-go-all-go, we mean that when one life-safety sensor on the network activates, all of the other interconnected life-safety sensors on the same network will also activate. This can be very important for ensuring that everyone in the building is alerted to the emergency.

But the downsides to the System Sensor COSMOD2W are glaring. This module is extremely difficult and tedious to set up. Most DIY users will not want to take on this challenge. You must also add a reset relay and a CO trigger relay. We almost always advise users to instead go with a setup involving 2-wire smoke detectors and 4-wire carbon monoxide sensors. This will require using separate system zones, but COSMOD2W requires this anyway. Overall, we do not recommend the System Sensor COSMOD2W. That is why it only gets 2 Stars from us.

Good: Combo Smoke/CO Sensor, Use at Any Wired Zone, One-Go-All-Go

Bad: Difficult to Set Up, Requires Reset Relay & CO Trigger Relay

Bottom Line: 2 Stars
