i got a household smoke alarm at Walmart today, and i cant find out how to wire it to actvate my panel and i need to know how. it has the usual red black and white wires we have all seen. i am aiming to wire it to use 24 volts or the 9 volt battery. heres what i want to happen: smoke activates it, sends a signal or continuity to my panel and activate the panel, then activate the alarms. any ideas or do you know how?
P.S. make&model Kidde/Firex i4618a ionization.

This is one of the reasons why I am always telling people to do the research before they buy anything.
You should put that smoke alarm back in the box and return it to Walmart, because what I am about to tell you will not provide the solution you wanted.
Residential hardwired smoke alarms interconnect through the red and the white wires, at 120 volts. Therefore, you cannot wire a residential smoke alarm directly to a fire alarm control panel without using a relay module. Unfortunately, these relay modules are not easy to find and if you find one, it’ll be so expensive that in the end it won’t be worth it. Between the smoke alarm and the relay module you’ll be spending more money than buying a cheap system smoke on ebay.
Furthermore, you cannot power a 120V smoke alarm with 24V as they were not designed for that – It just wont work and would probably mess up your panel somehow.
What kind of panel do you have? I can help you find a list of system smoke detectors that are compatible with it.
my panel is a (homemade) Nylan M32300U with a D21 dress/PUI control panel.
it has a slide switch for the silence, it has power, normal silenced and alarm indiator lights, single relay, single zone, california code 24 volts no retifacion ( i use some homemade 24 volt AC horns)
one NAC and thats all…
but i have an idea. wire a transistor into the horn with a voltage reg. and use a latching relay and an extra reset button on the panel then wire the lach into the IDC on the panel.
too much work or worth it? you decide…
