Hi, 
  
I had a water leak which came through the ceiling and destroyed my Menvia M12 4 in 1 detector. I sourced some Apollo Series 65 off a friend as replacement but I can seem to get them to work. The eurosec CPX alarm panel just reports fire zone 006 when i try and do anything on the keypad and the alarm sounds. Should these be compatible with my system? 
  
My wiring is as follows: 
  
red: +ve 
Black: -ve 
  
Yellow: Zone +ve 
Blue: Zone -ve 
  
Green and white: Earth/tamper 
  
the series 65 only seems to have L1, L1 out, L2, R-, and earth connections. It also has a diode between L1 and L1 out so not sure if I need this also? 
  
Any ideas on if this detecor will be compatable with my alarm and if so what is the correct way to wire it? 
  
Thanks!
