I'm after a little help replaced an old control panel with a Galaxy G2-20 some rooms have two shockguards in each running on latching. I dont have enough spare zones to split them so would like to run two on one zone as before with latching. They are wired double balanced, with a latching wire the shockguard manual say Latch requires +12 to terminal to inhibit LED upon removal will indicate if it has been triggered, my question is where can I get a +12v feed from the panel while it is alarmed and 0v when not.

dont do gals, but assume you can use an output and prog it to be set latch?

set o/p

agreed program the output to suit your need. The 2-20 will do it

Thanks for the replies.

Please confirm - So I connect to one of the Trigger header pins and configure the 'SET' to o/p hi when system alarmed.

Only concern is I have 4 vipers on latch, galaxy manual says Trigger header can sink 30ma per terminal but nothing about supply/source, also can't find any info on current required for each viper latch terminal, didn't want to connect in case I blew an o/p.

no no not the trigger header. If your going to use that you will need a t relay. There is another output on the board

you should be able to just wire them in series as normal, the detector itself does the latching. a normal +12v & 0v supply is all you need

yes but you would need something to reset the indication after an alarm.

Whats wrong with an old button screwed to the side of the panel to drop the volts

ah the old 'reset' button.

Nowt but not needed on the panel in use here, either use viper reset and supply them from the output or use latch freeze and an additional core.
