Hi
I recently upgraded my PIR's to iWise Quadsec anti mask, there are 7 installed in total. I would like to provide the detectors with a +12v on the set terminal when my gardtec 595 is armed (to disable AM when set), I think I can use PGM1 for this but don't know which setting to use on PGM1 and whether or not I can supply all the detectors from this terminal or if I need to fit a relay?
Many thanks in advance for any help offered,

Matt

Why are you using the anti mask?

[TTmjp]

Is it common to be left disconnected?

[fozzies]

Depends what grade the alarm is being installed to. if you are a diyer, then i doubt you need it at all, it can only cause trouble unless you choose the site for the detectors carefully, and your insurance company wont accept a diy installed alarm as a graded alarm anyways

Thanks for your advice, the system is DIY but all components are grade 3 and panel is setup as grade 3 with 2 wire eol on ELF1 wiring. I have enjoyed doing this system and although it won't provide any insurance backing I wanted to do a system that was more challenging than the run of the mill DIY systems. I have also installed a GSM dialler for instance! I have been researching the use of the PGM1/2 outputs on the Gardtec but can't verify whether they provide a current source or just a open collector output, thus is why I need help.

Tis not a panel i deal with, sorry, so i'll keep quiet so otjers can step in. have fun

My advice would be if you dont need it then dont install it, AM is a PITA to those that have to install it

PGM 1 & 2 are open collector outputs.

I didn't realise that they could be problematic, I guess if I can sort the +12v inhibit for the anti mask when the panel is set I can minimise any false alarms if they are an issue.

[PeterJames]

You may find inhibiting when set adds to the problems, if you dont have to use it (And I cant think of a good instance in most diy domestic applications as to why you would need to, unless you often invite really dodgy people into your house) then dont use it

Thanks RichL, is my only option to set output of PGM1 to any set with -ve output to a relay coil then? If so I would then supply the detector 12v mask inhibit through the relay fed from aux?

[fozzies]

Not sure i understand your post, sorry if you already understood this. open collector means either open circuit or 0v output, so you would need A relay to switch positive to the detectors. open collector also means no protection against over current, be certain what you are doing before you use it full stop. fried electronics are costly

[TTmjp]

Thanks fozzies, yes I understand that I will use the PGM1 as 0v for my relay coil and 12v from aux, I would then use a n/o contact on the relay to supply from aux 12v to the detectors. What I don't understand is why the Gardtec enables you to configure +ve or -ve function for PGM1, obviously in the above instance I would use -ve function?

where have you read that? AFAIR you can toggle the quiescent o/p state in the programming, I assume this is what you have seen.

In the engineering menu for PGM1 these are the 2 options, do I use -ve?

[topgunn]

use +ve and upon setting will put 0v onto the output!

Just ring risco!
