Heat sensor in the attic

    I would like to put a heat sensor in one of my attics. I have a
    chemetronics 601 in my laundry room. What should I place in the attic.
    Also I live in New Jersey.

    The 604 is a fixed temp 200 degree heat detector. If you're considering
    putting one up there, go with that. A RoR won't work in attics (even a high
    temp one). You're liable to get some false alarms.
     
  3. The 604 is a fixed temp 200 degree heat
    I disagree. The 602 (RoR) is designed for use in attics. I've installed
    hundreds of them in attics with no problems at all. Attic temperature can
    go high but it won't generally rise fast enough to set off a rate-of-rise
    heat detector. Just be sure to use a detector that's rated for at least
    190ºF. There are several brands which range from 194 to 200 degrees. They
    all perform about the same.

    I've seen RoR detectors set off in attics. The issues disappeared when we
    replaced them with fixed temps. The problem with attics is that they're
    prone to humidity as well as heat (at least they are here) which plays havoc
    with RoR's in time.
     
  5. I've seen RoR detectors set off in attics...

    If the temperature exceeds the rating of the thermal sensor they go off but
    that is equally true of fixed temperature heats.
    Use higher quality RoR's. I've been using them in attics for decades
    without any problems at all.

    Uh-huh... and how often have you actually tested their operation?? Just
    because they haven't false alarmed (and aren't visible), I'll bet you're
    *assuming* they're working. Our residential alarm contracts allow for an
    on-site inspection and test of our customer's alarm system on an annual
    basis. This costs the home-owner $50.00 and those that opt for it benefit
    additionally because we never charge them for replacement of the control
    panel's battery (when it becomes necessary). Otherwise it would be a $75.00
    charge (including the battery and labour).
     
  7. Any time I used ror high temp or not I have had problems with falses. I
    have never had a false with a fixed 200. Attics have fast air changes with
    fans etc which cause the problem and trick the rate of rise units in
    commercail buildings.
    I have seen this in barns as well that store hay in there loft area .

  8. Our residential alarm contracts allow for an on-site inspection...

    Our contract required an annual inspection and test which was included in
    our annual fee. We charged ~$20 to replace the control panel battery when
    needed.

  9. Any time I used ror high temp or not I have had problems with falses. I
    Having never installed a fire alarm in a barn, I can't dispute that.
    However, I've used ROR detectors in commercial and residential apps for
    decades and they gave no problems. Besides, attic exhaust fans only lower
    the attic temperature. A sudden *decrease* does not trip an RoR. That's
    not how they work.

  10. That was just a statement of experience. Try reading the post next time.

  12. Obviously you have not worked with the same amount of heat travelling thru
    roofs with big exhaust fans i have
    The flash of heat cuased by the air movement causes the false as it begins
    to pull extremely hot air thru the cooler area where multiple restaurant
    hoods and other high heat process hoods peneatrate the roof void areas .
    the units say right on them avoid areas were temp changes rapidly.
    I had a problem particularly were industrial furnaces and kilns are
    involved. put in the fixed 200 and never had another problem.

  13. The flash of heat cuased by the air movement
    What you describe is a very different environment from the typical attic.
    IMO it is not a valid basis for a decision not to ever use RoR detectors in
    attics.

  16. I have had RoR pop in conventional attics as well .
    And being a fireman I can tell you I have seen more than my share of them
    over the years go off.
    yet i have had attics with 135 RoR and they never falsed.
    it all apears to be design of the attic and physical size plus the type of
    roof and how it is vented as to it causing a problem or not.

    Mr. Bass did you read that.

    Per Mr. Markowitz.......

    "yet i have had attics with 135 RoR and they never falsed.
    it all apears to be design of the attic and physical size plus the type of
    roof and how it is vented as to it causing a problem or not".

    Ha, Ha, Ha, Ha, Ha, Ha,,,,,,I'm rolling on the floor.....

    How many years experience did you say you have Mr. Bass
    minus of couse the years in the Big House.......
    minus the years in Florida .......6 years I believe.
    minus the years in drug induced stupor........

  19. Norm,
    You don't sound much like a state official in your postings about RLB. I
    think you have let him get under your skin and cloud your usual clear
    thinking. Go back and read your postings.... Everytime you get off on Bass,
    you stoop to a level lower than the one you occuse him of being.

  20. I'm rolling on the floor.....

    Alcohol can do that to you.
