nick_smith Posted September 11, 2014 Share Posted September 11, 2014 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 Quote Link to comment Share on other sites More sharing options...
james.wilson Posted September 11, 2014 Share Posted September 11, 2014 id guess at cpo being as you said but dont know the panel Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

PeterJames Posted September 13, 2014 Share Posted September 13, 2014 C is usually common then NC and NO cant think what C P O could stand for? Stick a meter on it and test is the easy answer Quote Link to comment Share on other sites More sharing options...

morph Posted September 13, 2014 Share Posted September 13, 2014 P =Pole C = Closed O = Open on Controlled Equipment panels. Quote Link to comment Share on other sites More sharing options...
al-yeti Posted September 14, 2014 Share Posted September 14, 2014 Didn't think all three would connect to an alarm panel just like that, as above meter it but meter them with fire fault on and off to see which one gives you what you want, you might want to dis the sounders if you can when doing so Quote Link to comment Share on other sites More sharing options...
nick_smith Posted September 14, 2014 Author Share Posted September 14, 2014 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?

nick_smith Posted October 21, 2014 Author Share Posted October 21, 2014 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 Quote Link to comment Share on other sites More sharing options...
