Alarm Industry Products Heat Detector AI281B
Ken Abrahamsen
Products Heat Detector AI281B. I was wondering if anyone knew where I could
find the specifications and wiring diagram as I have one of these detectors
without the manual and do not know which of the connection pairs is for the
DC power (and which is the + screw and which is the - screw) and which pair
is for the alarm circuit itself. I did not notice any markings on the unit
itself to provide this information.
Thank you for any assistance. I tried to find AIP on the web but couldn't
locate them.
Sincerely,

No problem... Most heat detectors are normally open devices and have to be
wired in parallel with each other then supervised by an end of line (as the
last device in the circuit)... An alarm condition causes a dead short
across the zone. An "open" (broken wire/disconnected detector) will cause a
trouble.

That's most likely a private labeled Edwards 281B. The unit is a
rate-of-rise detector with a 135ºF fixed temperature sensor as well. It
detects a rapid increase in temperature typical of a fast-burning, flaming
fire. These are often used in places where smoke detectors are not
permitted, such as enclosed furnace rooms, laundry rooms, kitchens and
garages. There is some difference of opinion among installers as to whether
to use them in kitchens and garages due to the potential for a rapid
temperature increase.
The rate-of-rise part of the sensor is self-restoring. The fixed thermal
sensor is sacrificial. Once it reaches 135ºF the detector must be replaced.
The connection is simple enough. These sensors are open circuit. That is,
they close on alarm. There are two screw terminals on each side of the
sensor. Connect the fire alarm zone loop (also called an Initiating Device
Circuit, or IDC) to two of the screw terminals. Connect the EOL resistor or
the wires leading to the next detector to the other two screws.
For an explanation of fire alarm circuits, EOL resistors and other stuff,
you may wish to browse my FAQ site.

Another piece of bad advice... EOL resistors must be mounted on a separate
plate on most commercial/industrial/institutional settings... In a
residential setting this usually doesn't apply, but then this guy hasn't
given you any indication on what type of application this is or even where
he's located (Canada, US, Belgium...)...

Perhaps there's something different in Canada, but I'm in the US. Any
information I give is intended for a US audience. People living in other
countries should check with their local authorities.

That's an easy claim to make but not so easy to back up. State what is
erroneous and back up your claim with code reference. Otherwise it's just
more of your usual BS.

ULC CAN4-S524 Standard for Installation of Fire Alarm Systems... Yes, it's
a "Canadian" code... Since UL and ULC will be "merging" shortly, I figure
there's a good chance your guys will be having a good hard look at a more
stringent standard and adopting it. If EOL plates are "unheard" of in your
neck of the woods why would manufacturers be selling them???

Nope... I'm not in the business of helping the single most disruptive
participant in this newsgroup with "fixing" his FAQ... You picked out one
of the errors though... but, just one... Hopefully anyone with a lick of
sense that's interested in installing his own system will take the advice so
many have already posted (and that is to check out their local building
codes and AHJ before following the mis-information posted on some online
store's FAQ)...
Side note: I notice you no longer promote the one major "approval" you've
worked so hard over the years to get... ASA Online Vendor... You've never
been able to take any sort of criticism without immediately thinking it's an
"attack" or "flame".
Request: If you're going to be posting more of your "flocked-up" FWA's

who've disabled HTML on our newsreader... I'd hate to miss out on another
good chuckle...

If I was in Canada my post would not have applied to commercial fire alarm
systems. Since I live in the US and service DIY'rs (not commercial fire
systems) your response was entirely inappropriate.

Something you only learned from me.

Even if the merger does take place there are different requirements for
commercial fire alarms from residential systems. I've only a passing
interest in commercial fire alarms. You have zero experience with either
since all you do is sell parts at a distributor in Vancouver.

Perhaps they're real popular in Nova Scotia. Next time I drive up to Canada
I'll have to check.

Translation: You lied. There are no errors on the referenced page. In
fact, my information on fire alarms is directly from NFPA ( a book you
really ought to read some time).

That would be you.

You claim there are lots of errors but refuse to say where. Uh-huh. You're
full of crap.

Constructive criticism involves correction. You attack and post nothing of
value.

Simple... before he "spouts" off an answer he should be checking to see
*where* the poster is, and what kind of installation he's looking at
(residential, commercial, etc.). I take it when someone calls you on the
phone and asks a similar question of you, you just rattle off an answer
without first asking what the app is? It's bad advice if the answer's not
properly qualified...

Did you ask where the poster was located before spewing out your answer??
Did you ask what kind of application he's working on???

:-) I sell, service, install, and verify fire alarm systems, access
control, cctv, and security (mostly commercial these days)...

The standard I quoted doesn't just apply to Nova Scotia... Keep twisting...

Yeah... right... so you've reverted back to posting erroneous FAQ's and
more links to your web site...

Your FAQ's have no place in this group unless it's in response to a specific
question... Do simply post them does nothing but provoke negative responses
from other participants... That's your intention anyway, isn't it St.

Good... perhaps the individuals that come here looking for advice will see
what a total idiot you really are (and Jake, Mike, Graham, and others won't
have to point that out)...

Just for the heck of it I reread NFPA72 and NEC looking for anything that
specifies a requirement for a separate plate for EOL resistors. There's not
only nothing there to support your contention. There is actually a diagram
showing the EOL mounted directly to the last device in the line -- precisely
what I recommended and precisely the opposite of what you said.

How can mounting an EOL on a plate as the last device on the loop be
precisely the opposite of what you said? You continuously refer to NEC (the
US standard). I refer to ULC CAN4-S524 (the Canadian one). The latter is
apparently much more stringent than NEC. It also requires a separate
verifying agency and report to sign off on any new installs or additions to
existing ones.
You never bothered asking the guy where he was located (US or Canada for
example). The UK standard is pretty tough too I hear and a whole lot
different from NEC in many respects. You *assume* everyone that asks a
question here is from the US, then give advice that could very well
contravene their own AHJ's. What you should be asking is... Is it a code
violation to mount the EOL on a separate plate (one that's designed for it)?
No.
