Too many sounders for the panel to support?

Right there Oxo

Psu required i bet, and relay the sounders through it, and check what the panel is pulling to.

if your installing it to domestic fire regs then you need 72hrs back up

Wont get a big enough battery in the panel

just drill some holes in the bottom of the panel, extend the leads and cable tie or velcro a 18ah on, lol

always over complicating things mr c, just sit the battery on the floor

Probably only talking about putting in 2 or 3 Pyronix Dual Sounders - is that enough to be worrying about the amount of draw?

yes

If you look at what each one drwas when in full alarm, ie strobe and all, then compare that to your panel current output (- the keypad, panel itself and a few sensors) you will see why you may be in overload.

Id say in sab mode it will be too much for it.

3x Internal Sounders @ 160mA ea = 480mA

2x Novagard 6 @ 464mA (Max) ea = 928mA

---------

1408mA (1.4A?)

So with 1.4A on top of the standing draw of PCB, RKP's etc Im guessing it will probably be over.

Im not sure what the output capability of the PSU on the Galaxy 500 Panel is ?

What could be my next move ?

if you have a 1A oine then its 1A max.

If I add a Smart PSU to the system would that work ?

That way I can also add in a further battery ?
