System Sensor 2W-B

Is this smoke detector any good? I want to use it on my Ademco Vista
20. Or should I go with a 4-wire?

It is an excellent smoke detector.

I hope so, I use a lot of them.

Its a very good unit. You are better off with a two wire smoke. With a
four wire you need to install a power supervision relay module to do
it right.

Like others have said, good unit.


Remember though: Only one zone can be used for 2-wire smokes (Z1) so plan
your wiring accordingly.

If you are going to be using these in a residential setting I recommend
that you go with the 2WTA-B.

The 2W-B does not have a sounder in it. In a residential fire you want
as much noise as you can get.

I like the 2WTA-W (thermostat and sounder).

I do too. if it's not a wireless install, chances are that it will be a 2wb
or 4wb.

 

[Crash Gordon]

I use the thermos too...have a buddy that swears by the sounder option
too...I've only used the sounder ones where I've needed them though.

I use them with a reversing relay (# RRS-MOD I think.) It triggers sounders
on all smokes if any one trips.

dat be's code to have sounders in bedrooms, eh?

The 2W-B (2 wire) does not show up on the compatibility list for the
Vista 20. You'll have to use the 4W and an EOL supervision relay. Only
the following 2-wire smokes are compatible (see page 18 of your Vista 20
installation manual):

System Sensor 2300TB, 2400, 2400TH, 2451 w/ B401B Base, 2451TH w/ B401B
Base, 1400, 1451 w B401B Base, 2451 w/ DH400 Base, 1451 w/ DH400 Base,
1100 and 2100T

Use only UL approved compatible devices for connection to a listed
panel. And the pro's here should really check their facts before
opening their big yaps!

thought they did that automajickly?

Indeed. dat be's.

Donno, never tried it without the relay. The smokes are designed to sound
off if the polarity is reversed.

OK... So the question remains... why doesn't the panel manufacturer
list them as compatible? IMO, I would only install those detectors the
panel manufacturer lists.

because that Ademco manual was made years before the smokes were invented
and manufactured.

And your point??? Every FIRE ALARM manufacturer I know of provides a
list of compatible smoke detectors. The smoke detector manufacturer is
interested in selling... smoke detectors... and hopefully gets
included in that list. How does a smoke detector manufacturer determine
whether-or-not his new "little gem" of technology is going to be
compatible with say... a Mircom 300 series panel, or an Ademco Vista 20?
I somehow think the procedure involves a resubmittal (to UL) for
testing (which would also involve the panel manufacturer's engineering
department). I haven't seen Ademco publish an updated list anywhere.
Seeing as how I'm taking on the responsibility of installing a system,
I'm also responsible for ensuring that the life safety devices connected
to it are, in fact, compatible. Therefore, the panel manufacturer's
list is the one I go by.

I'll call up Honeywell later today and see if they've got an updated
compatiblity list. I do happen to like the C2W's. They are my smoke
detector of choice.
