hi im looking to buy the ADE Accenta Mini Gen4 Starter Kit with LED Keypad, 2x Quest PIRs and also the Klaxon 127Db 240v High Output Master Blaster Siren (12v Relay) and was just wondering if the klaxon will work of this alarm panel. thanks in advance.

The relay requires 33mA at 12v. The trigger outputs on that panel only sink 10mA, so you cannot use those. I don't see any info (having a quick look at the manual) on the bell output current, but they would normally sink around 200mA, so depending on what you have connected in there already, you need to add the 35mA and see what the total is. Remember to wire one side of the relay to +12v and the other to the output.

 

Hopefully there's a diode on the klaxon relay coil to stop any reverse emf. I couldn't see any circuit diagram showing this.
