12v Terminals - Or Direct To Battery ?


Recommended Posts

decent panels have a seperate fused output for signallinmg devies as stated.

Fair enough - I forgot to mention that I am dealing with American control panels and they tend not to have a seperate output for signalling devices. Unfortunately, I cannot dictate if a customer has a decent control panel or not and that's why I wanted to know about the 12v output.

I'm writing the software side of the manual and have not been involved in the hardware side to date, however, I spotted something in that section regarding wiring that I wasn't too sure about. As far as being qualified goes - I have installed well over 500 monitored alarm systems in my time, but I sold up over 5 years ago and am a little rusty in that department (plus I'm getting old :( ).

breff: Thanks for the info on the Texecom panel. Noted.

ALSEC & Mr Happy: I don't know the answer to this question - that's why I made this post. It seems neither of you do either. Why not let everyone on the forum know how clever you guys are and give us an in depth technical explanation of the difference at the battery terminals and the 12v panel terminals. My 8 year old daughter had already told me about the Aux supply and that there would be no fuse !

Calm down - looks like someone can't take critism! I'm not trying to show off - it's just a very obvious answer to a very obvious question that should already be known by someone who is writing documentation that possibly 100's of engineers will refer to to connect your equipment to a range of other equipment.

A galaxy will disconnect the battery if it reaches over 14.5v (please correct me if i'm wrong) - if you IP unit was connected to it then it as well would be disconnected and the alarm would not signal!

You should have listened to your 8 year old daughter because she already answered the question!!!!!

:hmm: i wonder why they bothered to provide separate fused 12vdc supplies (from common source) for aux, battery, node network, rkp network & sab on the networker stuff?? & unfused wire on digi........

who's the nut in nuttsoft??

reasons not wire on a device on to a battery charging ciruit?

load test?

disconnection due to low / high volts

fire risk, the fuse will remove the 12v from the panel but not the battery (intruder alarm battery leads are unfused)

call me a smart ass why does your device not have its own internal battery then......... :whistle:
