As I mentioned in previous posts, I have this alarm panel that uses
12VDC to power a set of output contacts for an optional sounder
device. The only requirement is that you don't exceed 120 mA current
draw @12VDC for these contacts. Thanks to the help I've gotten here, I
was able to measure the draw from all of my sirens, as well as some
small strobe lights. Now here's my question. My lowest draw siren
draws 50mA. That leaves me another 70mA free on that circuit. I have a
low draw strobe assembly (strobe light w/ little circuit embedded
under it) that I'd like to add to the siren, but it draws. 140mA @
12VDC...too much still.
Is there anyway I can modify the strobe so that it will draw only 70mA
rather than 140? Maybe with a resistor or something? Before you say
it, I know that there is the possibility that the strobe won't fire or
be pretty dim...but...I'd like to try it anyway. Thanks again for the
great advice I've gotten here.
