Hi. I'm looking to replace 3  660MBX's as 2 are now intermittently triggering and all are within a year of their end life. The site shows a suitable replacement; easichange® SBBRKSM  but at various points mentions a twist fit base. The bases on all mine are the push fit type, as shown with the 760MBX. Can anyone confirm that the easichange® SBBRKSM will happily connect to this push fit base?

Good morning

the SBBRKSM alarms will fit your 660MBX push fit bases however the colour of the SBBRKSM doesn't quite match your unit. Additionally the 660MBX push fit base is already a deep base which will in combination with the SBBRKSM alarm result in a bulky unit. So you can use the replacement but it might not be aesthetically pleasing.

I hope this helps.
