Doing some redecorating and decided to replace 15 year old dicon alarms with BRK 670MBX.
1 in kitchen one on landing.
Disconnected kitchen alarm and had to change over connection.
No problems there only three wires. Cable supplying power colours blue , yellow red(EARTHcutback inside sheathing.) Connected new alarm as old. Blue to blue on connector Yellow to white and red to brown.
Turned on power and both alarms started sounding.
Disconnected upstairs alarm.
Checked the wiring for upstairs and I have 2 cables running to it.
First cable red , black and earth. 2nd cable red , blue and yellow..Both have earth wires joined together.
Both reds are joined together and black and blue joined together.
Connections to alarm the 2 reds are connected to the brown wire on alarm , white is connected to yellow.Blue is not connected. When removing original alarm this was either not connected or came loose.Looking at the wire it doesn't appear crimped and the connector block screw is fully in.
Any ideas to get both alarms working properly.
