## Questions & Answers

**Q: I have 20 year old ones in a new house model ei 161, will there be a standard fitting and just click into the existing ceiling mount?**
A: I believe so.  I inherited 15 year old ones and the new ones just replaced them

**Q: do these alarms come with base plates ,because they probably wouldnt fit the old DETA base**
A: I had to make up some stand off from the ceiling because the base would not fit over the ceiling rose I had. The base on my units were solid , no holes for the rose. hope this helps.

A: Hi This Model EI146RC Replacement for EI141RC.
I'm sorry i can't recognise the model EI161RC

**Q: Can you tell me the replacement date indicated on the product please?**
A: Sorry not sure but think it is generally 5 years.
