Smoke loops

<p style=”text-align: left;”>I have 2 System Sensor COSMOD2W in an M1 Gold panel. Can they be connected to the same zone on the main panel or do they each need their own zone?</p>

[Brad Weeks]

Generally the COSMOD2W is used in conjunction with the System Sensor i4 Series combo Smoke/Co unit and the COSMOD2W will provide two separate zones to a control panel one for smoke and the other for CO each zone having its own EOLR.

<p style=”text-align: left;”>Yes, understood. But can I tie both smoke zones from the COSMOD2W’s together on one zone on the M1 panel? Hope that makes sense.</p>

The COSMOD2W Interface allows you to configure the Panel EOLR on the COSMOD2W therefore you can use a 2.2K Ohm Resistor and connect the output from the COSMOD2W to any zone configured for 4-Wire Smoke. In this way you are not limited to using Zone 16 for smoke detectors.

Ok, thanks for the explanation.
