System Sensor 2WTA-B compatible with ELK M1G?

[HighTest]

Does anyone know if the System Sensor 2WTA-B is compatible with the ELK M1G? I know that the sounder may restrict the number of smokes to a smaller number if compatible, but I only need to support 7 of them.

Here's the System Sensor webpage. http://www.systemsensor.com/html/cd.html?UniqueID=59 I noted that none of the smokes list the ELK systems, so it's difficult to determine compatibility.

Thanks in advance!

Yep, I am using them (at least for now)

Does that mean you'd prefer to use something else? In addition, are you using a reversing relay to enable them to sound all at the same time?

Thanks!

I looked at the SS website and I can see that it is incomplete since I had 7 panels evaluated for use with that detector earlier this year and they are not on the website.

If you call ELK tech support they should be able to confirm either way. I know that the version without the sounder was evaluated by UL and appears in the instruction manual. The " VI Curves " for the detectors with and without the siren are different though

I believe a few people on Cocoontech have used the 2WTA-B's with the ELK. If you use more than one you will need the reversing relay I believe to support the current draw of the sirens and trigger all of the sounders when one detector goes into alarm.

Again I would call ELK as they would have all of the details for their panel.

Found the following on their support site. Spanky, I'll delete this post if I'm not supposed to post this information.

From Brad Weeks on the Bulletin Board.

The System Sensor RRS-MOD Reversing Relay / Synchronization module has not been evaluated by ELK PRODUCTS but you should be able to use Figure 3 2-Wire system triggered from alarm relay contact:
T+ Purple Wire connect to N/O on Output 3 of the M1
PWR + Red Wire connect to +VAUX on the M1
PWR – Black Wire connect to – VAUX on the M1
Out + Brown Wire to the + on the 2WTA-B Smoke detector
Out – White Wire to the – on the 2WTA-B Smoke detector
IN + Yellow Wire connect to Zone 16 on the M1---JP1 set for 2-wire smoke
IN – Orange Wire connect to Neg (Zone16)on the M1
Connect a jumper from +VAUX to COM on Output 3 of the M1
Create the following two rules:
Whenever Any Fire Alarm Turns ON Then Turn Relay 3 (Out3) ON
Whenever Any Fire Alarm Turns OFF Then Turn Relay 3 (Out3) OFF
ALL detectors should go into alarm and start sounding
When the customer enters their code xxxx the sounders will turn OFF
At this point the customer will be able to walk around the residence to see which detector went into alarm indicated by the RED LED
To clear the Fire Trouble on the keypad press the ELK button, then press the number 2 screen will read 2-Rest Smoke Detectors
Next Press the right arrow key

Not really, just that I have been debating moving to 4 wire, or if I started over I would consider the very similar ones from DSC that AO recommends. I do have the reversing relay but have never got it working right. I basically gave up on it at the time. I only have 2 of these right now. When I do my relocation/expansion I will add more and thats when I'll decide if I go 4 wire or just expand upon this.

I would go 4 wire if you only have 2 existing to deal with. I personally have several 4WTA-B and a few 4WTA-R for disabling HVAC. They work well without the concern for compatibility or quantity of devices

Well, 2 vs 4 wire has been debated here many times. The only real advantage I see to 4 wire is the fact that each one is zoned so you know immediately which one went off. I see this as a possible benefit either in a very large or multistory house, so 4 wire really would not have a huge benefit for me but I was just considering it since I am homerunning my pir/gb wires anyway for each room and I am adding a smoke to each room while I'm at it. The downside is you need a power supervision relay for each detector/zone and that adds to the cost. I probably could get the RRS-MOD working if I tried hard enough, but it did not work according to the directions earlier (possibly a bad unit to?). But the smokes themselves are very good and high quality. But I am also considering doing away with the models with sounders anyway and just turning on several of the Moose piezo screamers during any fire alarm. They will be just as load if not loader and eliminate any issues with RRS-MOD.

i have installed several of the reversing relays and they have all worked if you use the right diagram, rules and remember to turn on the mini switch on the side of the relay. In my own house I have 6 2WTA-B 's on my Elk with no problems.

I don't know about the Elk but I have installed loads of these System Sensor smokes of a variety of part#s all have served well. I can't recall a single issue.

EXCEPT!

The damn terminals on them suck, and this effects all that use the 2wt or 4wt baseplates. I still use them but I have stripped the screws in a few and been SOL.

I agree. The baseplates are very touchy.

I hear you.

I don't have them zoned individually. They are all on one zone with one EOLR. I really don't care which one goes off. If there is a problem I want everyone out of the house, end of story. I'll worry about which one caused the alarm after everyone is safe.
