Hi guy’s 1st post for me here, I’m just a little confused as regard’s to the current rating of the AZ-TECH AZ220 external sounders. The “spec” says:- 370mA in full alarm, 160mA strobe, and 18mA in a quiescent state. I want to replace the 2 old (and knackered) sounders connected to my Optima compact panel with 2 of the above units. The bell/sounder panel output is protected by a 1A fuse and I want both sounders to run in the “SAB” mode for maximum output volume. Do I assume that 2 x 370mA. which equates to 740mA will be the maximum load drawn from the panel in alarm conditions or do I add on the other values mentioned in the “spec” ??
