Idea for Integrating Hard Wired Smoke Alarms

Okay I have no alarm panel I do have Kidde fire alarms that are hardwired and interconnected. I have a mixed system some CO2/Smoke and some pure smoke.

Can someone please tell how I simply setup something that will send an alert to VeraLite and also allow me to trigger the alarms to act as a siren. so far everyone has pointed to having to use an alarm panel.

I am wondering if KIDDE SM120X SMOKE ALARM RELAY MODULE FOR 1-COMBO UNITS at

it appears it has 3 wires coming in red white black, the same as my alarm system so I would guess you could wire them direct behind an alarm.
and 3 wires coming out an orange/blue/yellow now what do you connect these to and how to setup on Veralite.

I think this might be better than using FirstAlertZwave or NestProtect. I don’t have to buy a all new alarms that don’t talk.

thanks

Well I’m confused do you have an alarm or not?

If you don’t have an alarm and wanted to just trip a sensor in vera you would use the relay modual wired to a z-wave contact sensor. Almost all z-wave wireless door/window sensors have an aux 2 wire input you can use.

Okay guys this it.
I think this link is the best link and simplest for wiring your existing alarms to use with Micasaverde.

Depends on that your trying to do. This is wired so you can trip (manually setoff) the smokes with a mimolite.

If you only want to know when the smokes go off then you don’t need a Mimolite.

According to the article it is wired to do both manual trip the alarms and also know when the smokes go off/ dual purpose

Correct but the original post was not about that. And would not need a 60.00 Mimolite to complete his task. A simple door/window contact would do. Half price.

So again depends on what you want to do. If you want to manually trip them (which you seem over joyed to do) then mimolite is good, if you only want to add to your alarm panel or vera which is what the OP was asking for then Mimolite is over double the price and more wiring when it’s not needed.

I’m surprised this worked. The SM120X I bought needs some sort of a load in order to switch the relay.

You talking about the orginal post where you want the smokes to send vera a trigger when they go off? Or are talking about the part of thread that got off topic to have vera manually trip the smokes to use them as sirens? The second part requires a mimolite which is a zwave relay?

The relay in the sm120x gets switched by the high voltage from the smoke alarms going off.

I’m surprised that anyone would want to use the smokes as an alarm siren!!

hypothetical scenario… Someone breaks into your home… Vera sets of the smoke alarms… neighbor hears smoke alarms going off and calls fire department… fire department arrives and is confronted by a burglar!!
— or —

your neighbor, hearing the smoke detectors, goes to your home to render assistance and is confronted by a burglar!!!

This is the reason that smoke/fire/co alarms sound different than burglar/break-in alarms… and the reason that the fire code in almost all jurisdictions prohibit the use of fire alarm sounders for any purpose other than indicating an actual (or suspected) fire event.

Having the Vera setup to trip the fire/smoke/co alarms also exposes you to criminal liability… In the scenario presented, if a first responder (firefighter or neighbor) was injured, you are liable!!! You may think that you are using the smoke alarms as a deterrent to a burglar, but you are luring unsuspecting persons to an inherently life-threatening situation under false pretenses.

To the point…

DO NOT SETUP ANY SYSTEM TO TRIGGER A FIRE/SMOKE/CO SOUNDER UNDER ANY CONDITION OTHER THAN AN ACTUAL OR SUSPECTED FIRE/SMOKE/CO EVENT!!!

Having the smoke/fire/co system notify the Vera so that it can take additional action is ok, but NOT the reverse…

Hey guys, resurrecting this thread. I am interested in having Vera send a text if the smoke alarms go off. So just monitoring, no control.

I see that the SM120x has normally open & normally closed signal wires so one of those could be wired to a door/window sensor to let Vera know of a activated state.

So good so far, but these things are too big to fit in the elec. box, right? So you need to find somewhere to put them. And the battery needs to be changed after a year or two. Can they be powered by the relay, or is there some other device that solves these issues?

I guess one advantage of the Mimo Lite is that you can power it with an adapter. But still, need to put it somewhere.

It might be easier to just get a couple of zwave smoke detectors. Unlike the Nest units, these seem to work as expected.

We looked into them but that’s not what I’ve been reading. Sounds to me like they’re still having problems with false alarms. Anyway, it’s new construction and they’re installing 6 smoke alarms. They’re all going to be connected. I’ve realized that I can run a wire to a 4 square box in the garage ceiling. In that box will be the relay and a Mimo Lite which we’ll also be using to control the garage door. So I think I’m all set on this one but I still have these questions for retrofit applications.

The wired smoked detectors have an optional relay you can buy (that is designed for this purpose) that is tripped when any of the smoke detectors are tripped.
It’s wired to the same 3 wrires that tie the smoke detectors together.

You can use that to signal a wired door switch. I actually have it connected to my alarm system … and that is connected to my Vera.

I wired my relay to an Everspring door contact and simply placed the module outside the box. I used double-sided tape to afix it to the ceiling right next to one of my smoke detectors. It’s one that is in a corner, so I placed it behind the detector and you can’t really see it.

Hi all!

Sorry for resurrecting this old thread again. It’s the closest one to what I want to do. I’ve read it twice and I am still a bit confused.

I’m kind of a noob so please don’t assume I know the basics if you elect to to me a favour by answering this post.

So, what I want to do is integrating my Kiddie interconnected hardwired 120v system to a DSC 1616 panel. I just want the panel to know if the alarm is tripped, nothing else.

From what I’ve read in this thread, I’ll need to buy the Kiddie SM120x relay.

This is where I get a bit lost. Where in the circuit should I put the relay? Between the panel and a smoke detector or between two smoke detector? Does it even matter?

Then, how should I wire it? I’ve looked the instruction manual for the relay but I’m not sure one of the 4 figure applies to what I want to do.

You guys mentioned that the relay normally closed, normally opened and 9v output should be connected to a door contact or something… Can’t I simply connect the wires from the relay to the panel? If a contact is needed, can you explain why? I’d like to understand the concept of how it works.

Last question, I’ve seen a video on YouTube where a resistor was used along with the relay. Is it necessary? What does it do and I should I connect it?

I know it would be ideal to wait until I have all the devices in hand, but my wife insist on being sure we can connect the smoke the detector to the alarm before ordering everything… I’ll get into my beta questions later on.

All of the smoke alarms have a RED wire which is a signal wire (5V between the white wire and red wire to signal a trip). (i.e. they are all wired in parallel … same with the relay)

You can install this relay next to ANY smoke detector … then you will have access to the
Black/White (110V)
Red/White (Same white as above) 5 Volt Signal.
This will cause the relay to trip when the alarm is triggered.
Then you use the relay contacts to trip a zone on the DSC. You will probably need to put some resistors in the circuit to conform with the wired zone termination you have configured your alarm system with (Single, Double, or NO termination).

I do this, but I also have a relay, triggered by Vera that will inject a 9V battery onto the Red/White wire … then I have whole house alerts!
