Replacement smoke alarm for 2Gig

I’m currently have a 2GIG smoke & heat detector: 2GIG-SMKT3-345 that is now expiring. I’m looking for a replacement. Is this model the closest replacement given that my model no longer available? Does it require reprogramming when replacing the detector?

Yes it’s the replacement. Not sure about reprogramming but at a minimum you would have to update the sensor ID.

That’s the replacement. Steps to program the new sensor can be found here:

You can either delete the existing zones and learn the new sensor in, or you could overwrite the sensor TXID, the rest of the programming would be the same.

Thank you both of you for confirming!
