UPDATE as promised

I ordered 2 Kidde 2040 units ($30 delivered) from Amazon.com. I replaced the defective Kidde 1275 unit with the newer model. Many of the Kidde units can be mixed and matched . I tested the system and all worked well.

I subsequently found an oversupply liquidator of the original Kidde model 1275 units on Ebay. I won a lot of FIVE for $30 delivered.

I noticed some unusual discoloration on the alarms mounting plate, it was yellow as if a hot/warm component of the original smoke detector was in contact on the mounting plate and discolored it.

So with my extra six units I will be replacing the original 7 year old units with the new ones.

I will compare the technical specifics of the two different models. I think the new unit isn't as loud. . .

Stand by for additional updates
