Hello everyone,
My retired father is in the process of doing DIY home security system. They are in South Auckland, and the bad guy was trying to break in, while my father was sitting in the garage, listenning to music (!!!). Now my parents are under huge stress, and really need your help, guys.
He's got a siren, which used to be very common in New Zealand sometime ago, but there is no brand name, no circuit diagram, and no specs. Photos are attached.
The questions are: What's the voltage, polarity etc for this piece of equipment? If he just wants to run it, using a power supply, how shoud he connect the power supply and what kind of power supply does he neeed?
He wants to be able to run the siren(and the strobe light) remotely, by using a "smart home" relay.
If someone could help, my parents and I would really appreciate the help.
