3 Sirens and a Strobe + Multiple Wires

[adfundum]

I have three 1 Amp Sirens and a Strobe.  In reading through the manual and looking at various posts I have reached the conclusion that I should place all 4 devices on a separate power supply and connect them to Output 3 with a Relay.  Any suggestions on what relay I should buy to handle this? 

Secondly, when wiring the power for multiple motion sensors has anyone come up with a good solution to wire 12-16 22AWG wires together?  I have heard of a bridge but the ones I have seen only bridge two wires together instead of bridging 1 wire to 16 outs.

I use terminal strips. Pictured is my "Wallwart Elimination Project" - I have another terminal strip used only for motion and occupancy sensors.

Monk, installation looks great.  You may want to consider using a power distribution module, such as the Elk PD-9* series, as it will fuse protect each leg (so you don't risk shorting out the entire supply if one of the distributions is shorted).  Of course, their current limitations (depending on the model) may not be high enough for your applications).

Agreed... I use terminal strips for everything - speakers, screamers, power, etc.
 
Though, I would advise to wire the strobe to it's own output. I use mine for basic notifications and to stay on longer than the siren for burglar/fire alarms to help guide the authorities.

You don't need to buy a relay.  The OUT 3 relay is rated at 4 amps and will handle your load.

Is it feasiblle to intercept the battery to provide power for the (3) 1 Amp Sirens and Strobe?  I could run the positive from the battery through the N/O circuit on Out 3 and connect to the positive on the sirens wired in parallel.  The negative of each siren would go directly to the negative of the battery.

Don't do it.

So should I buy one of those 12 VDC transformers that you use for doorbells to power or something else?
