As many already know I am the full time caregiver for my 96 yo mom, so she's living in the same house. I have a "call" system in the home where she can press a button on a pendant and remote speakers sound a 'chime alarm' - telling me she needs something. In other words it is a one way system to signal me. The speakers are wireless receivers that plug into regular wall sockets, and the pendant is a battery powered transmitter. The button on it activates all of the receivers at once, which can be programmed for the "chime" tune and volume. Unfortunately the system has a fairly limited reach (wireless) for the signal, and the speakers are not loud enough (at full volume) when I'm out on the property or have equipment running. So I'd like to "hotwire" a couple of the receivers to allow two things; 1) keep the receiver located within range but extend a pair of wires from it to a further distance, where, 2) the wires connect to a much louder speaker. But I need some help with how to do this.
I opened one of the receiver-speaker assemblies. It is very simple inside. The 110V supply goes directly to a small circuit board, there are 3 controls buttons (volume, menu up and menu down), then a pair of wires to the onboard speaker. I could not find any schematics for it so I don't know if the circuit board changes the voltage from 110V to something less (I suspect it does). Therefore I don't know what sort of speaker I can attach to the speaker output wires if I splice into them.
Here are photos of what's inside the box (I left them large, click on them to see detail). I'm hoping some of you can look at them and understand what it is, in order to help with the project:
The red and white wires coming from the bottom are the wall plug. The red and black wires barely showing behind go to the onboard speaker. The onboard speaker says "16 ohm, .25 Watt".
The three push buttons on the right are as described, volume, menu up and down (for chimes).
You can see one of the little capacitor cans (I think it is) says 10V on it.
Here's the little on board speaker.
It will be easy to clip the two speaker output wires and extend them to a seperate speaker. But what spec of speaker will work? Will I need to add a relay and external amp to power a larger speaker?
Really appreciate any help in doing this. It will be a huge benefit to my mom and I.
