Hello all
I'm about to install a burglar alarm siren box outside on my house's exterior wall powered by an ordinary power supply running at 12V 300ma/0.3A. (the power supply is indoors)
As i bought this cheap(ish) on Ebay i have no guarantee that the siren is weatherproof like it is advertised.
Are there any safety considerations related to fire i should be aware of please?
The worst case scenario - rain water manages to get into the siren unit and shorts it out.
I assume this low current wouldn't cause the siren box to catch fire but could the power supply that is powering it heat up to dangerous levels in these circumstances?
Do these cheap chinese power supply always have fuses? Would the household fuses protect me or could the power supply catch fire?
Many thanks.
