I posted a while ago re: problems with the Fire Alarm system in a block of 7 flats, and have now established the following:
Panel - MFP Range 4-28 Zone Fire Alarm Control Panel.
End of Line Device specified 6k8ohms
End Of Line Devices supplied are ZF19 which seem to be 8k2ohms.
Presumably, the ZF19 will not be suitable, and has been wrongly supplied?
Any ideas welcomed
