Hi there, my first post so please be kind. I have a Response wireless alarm system with wireless siren. I have south facing garden so my only current working siren with it's solar panel for charging the internal batteries faces south for good charging but this is on the rear of my house so not a lot of people can see or hear it if it were to go off. I have bought another wireless solar siren to mount on the front of my house & the manufacturers recommend not mounting it facing north to prevent possible charging issues with the PV panel, so my question is this...
• How do I effectively replace the solar panel with a mains fed system?
• Use a power supply & get rid of the battery? Of course output has to be rights amps to allow siren & LED strobes to fire correctly.
• Use a charger permanently connected to the battery or the solar panel leads? (that i'll probably cut off if I do it like this).
• The battery is a 6vDC, 1.2 Amp hour lead acid unit.
• I intend to take a feed from my upstairs lighting circuit for the power duties (6Amp MBC) which I'm sure will be able to handle the relatively short & infrequent use it may get.
• I intend to mount the siren unit high on the house & drill a large(ish) diameter hole for the cables so I can have all my power on the inside of the house in the loft to aid maintenance tasks in future. I will need to solder some flying leads onto wherever I need to within the siren box itself for the 9v back up battery & also for the main charging or power leads that I am asking these questions about.
If anyone has any other suggestions that I haven't mentioned, please do so as I am a bit lost as how to get the result I want. It must be possible to do as it just looks like replacing a small source for charging with another small source for charging.
I have tried to get some spec off the manufacturers' website but there is no technical detail regarding solar panel output (this must vary somewhat dependant on light levels? does it??????) Is there normally some sort of current limiter for when it gets really bright?
Thanks for reading & any answers given, Gregg.
