Thanks for all the assistance with this. I have connected to may alarm panel and tested successfully. For the record:- P =Pole C = Closed O = Open

Thanks for all the help so far. So I have put a multimeter across it and measured the resistance both Fire and Fault outputs show similar readings:- "Fire" P to C resistance when in normal mode = 0 "Fault" P to C resistance when in normal mode = 0 "Fire" P to C resistance when in alarm mode = Meter reports over range "Fault" P to C resistance when in fault mode = Meter reports over range Which if my understanding is correct confirms this would be a normally closed circuit? "Fire" P to O resistance when in normal mode = Meter reports over range "Fault" P to O resistance when in normal mode = Meter reports over range "Fire" P to O resistance when in alarm mode = 0 "Fault" P to O resistance when in fault mode = 0 Which again if my understanding is correct shows this would be a normally open circuit? Are my assumptions correct and should there be anything further I should check before connecting to a spare zone on my alarm panel and testing?

Hi, I have a conventional fire alarm panel installed in my home that I would like to connect to my intruder alarm mainly to take advantage of SMS notifications should a fire or fault be detected by the fire alarm panel when I am away from home. Please note the fire alarm panel will remain connected to the existing sounders and I have no intention to interfere with those. The fire alarm panel is a conventional two zone "Precept 2" that I believe has volt-free outputs for fire and faults that I want to connect to spare zones on my intruder alarm. The Outputs are labelled "Aux 1 Fire" "Aux 2 Fire" "Aux Fault" all have three terminals: C, P, O. Does C = Closed, P = Pole, O = Open ? I was not left any instruction manual so do not know which terminals to connect to my intruder alarm and would appreciate any advice. The Precept 2 panel has a C1440 display board and a C1423 motherboard (and yes it is pretty ancient). Thanks, Nick
