Thanks for the reply. despite the answers result .
I bought the power master 10 and under the product it said others that bought this also bought: the mct-427. i was a little trigger happy maybe and i hope i can return and exchange my 2 units. i will email you about this.
once again. thanks for fast reply!
I can not connect the mct-427 to the power master 10. No id for the units in the boxes and when using the instruction of holding down the test button during enrollment in the main panel nothing happens.
is this detector compatible with the power master 10?
