Re: smoke & Co alarms
10.4.2.2* Fire alarm systems and other systems and equipment
that are associated with fire alarm systems and accessory equipment
shall be tested according to Table 10.4.2.2.
From Table Table 10.4.2.2
(g) Smoke detectors
1. System detectors and single-station smoke alarms used in other than one- and two-family dwellings
The detectors shall be tested in place to ensure smoke entry into the sensing
chamber and an alarm response. Testing with smoke or listed aerosol approved
by the manufacturer shall be permitted as acceptable test methods. Other
methods approved by the manufacturer that ensure smoke entry into the
sensing chamber shall be permitted.
Any of the following tests shall be performed to ensure that each smoke detector
is within its listed and marked sensitivity range:
(1) Calibrated test method
(2) Manufacturer's calibrated sensitivity test instrument
(3) Listed control equipment arranged for the purpose
(4) Smoke detector/control unit arrangement whereby the detector causes a
signal at the control unit when its sensitivity is outside its listed sensitivity range
(5) Other calibrated sensitivity test method approved by the authority having
jurisdiction
2. Single- and multiple-station smoke alarms
Functional tests shall be conducted according to manufacturer's instructions.
Summary
10.4.2.2 G 1 States that Smoke DETECTORS and Smoke ALARMS in OTHER THAN 1 and 2 family dwellings shall be tested using smoke. Additional testing must also be performed using 1 of the 5 methods shown.
I doubt any one here (with exception of myself) is qualified to test using any of these methods.
10.4.2.2 G 2 States that Smoke ALARMS ( this is what you get at HD, Lowes, WalMart...) are to be tested using the manufactures instructions (IE Press the button)
In addition
ALL ordinary smoke alarms do have a test button.
Smoke detectors like those used in a Fire Alarm System have hidden test buttons or another method for testing.

Re: smoke & Co alarms
So you think I'm wrong?
And just what are your qualifications to make that statement?
You sure can't comprehend what you read.
Ya see Jim, I don't just talk the talk, I also walk the walk.
Meaning, I started in the burglar and fire alarm business in 1986.
I was state certified and got my state licensed in burglar and fire alarms in 1995.
Now that doesn't mean that I know it all, but I'm sure I know more than you.
There may be somethings you are qualified to speak on.
Maybe Bevis and Buthead, or even Family Guy.
But when it comes to Home Inspections, well, I have sympathy for your customers.
So, now that I've said that, let me ask you something:
How do you feel about testing for MOLD?

Re: smoke & Co alarms
........ok! I called First Alert, they too said the test button tests the operation and not just the battery! Please just drop it.

Re: smoke & Co alarms
I'm the same way, I don't test them because who knows who does what or what happens to the property for the next 30-45 days till the new owners move in? My boilerplate comment states: "Due to liability reasons, smoke and CO detectors are not tested nor evaluated. Recommend testing devices on first day of occupancy to your own satisfaction".

Re: smoke & Co alarms
Jim
Now this (your post) is a reasonable reply
We can disagree on things, and still be reasonable at the same time.
So in answer I will break it down.
That was an acceptable response
I never said that. I said that a HI should not test smoke detectors that are part of (connected to) an alarm system. The reason is mainly because, unless someone is there with the alarm code (or key) the HI will be unable to silence the siren. Also, An HI, is not quilifed to perform testing on a fire alarm system.
Yes, they do need to be tested, however much like checking freon, that testing is beyond what most HIs can/ should perform.
Of course it excludes one and two family dwellings. That is why it says " Excludes one and two family dwellings".
No, it's not confusing. You left out two key words "SMOKE ALARMS"
It's not uncommon to have single station smoke alarms and yet have a fire alarm system also.
So on all buildings (other that 1 & 2 family dwellings) in addition to testing the smoke detectors with smoke, the single station smoke alarms are to be tested with smoke also.
But as I said earlier, even when you inspect commercial buildings, apartments, and similar, you, as an HI should not be testing any of the smoke detectors on smoke alarms.
I can't say for certain that you are wrong, however for many many years pressing the test button actually does perform a calibrated test of the smoke alarm.
Jim, first let define a few terms, OK.
A smoke ALARM is contains the smoke sensor AND an annunciator device (sirem, light, beeper)
A smoke alarm can be single station or interconnected with other smoke alarms.
What you'll find in most houses are SMOKE ALARMS. This type on smoke alarm you can get at HD or Lowes.
There are some SMOKE ALARMS designed to be connected to a fire alarm system. This type is not the same as a smoke alarm you get at HD, or Lowes. It is a smoke alarm in that it has the smoke detector AND the an annunciator and also connects to the fire alarm system.
A SMOKE DETECTOR has the sensor to detect smoke, however it does not have an annunciator contained within the device. A smoke DETECTOR is always connected to a fire alarm system.
A fire alarm system may or may not have SMOKE DETECTORS, SMOKE ALARMS, connected to it. Many fire alarms only have pull stations.
Fire alarm systems may or may not be monitored (call the fire station),
That said:
You are (somewhat) correct when you said smoke DETECTORS do not have test buttons.
Remember smoke DETECTORS are part of a fire alarm system. The smoke detector does have a way to test it. Smoke DETECTORS have a concealed test button, magnetic switch, or a special KEY for testing.
ALL smoke ALARMS like those you get at HD or Lowes have a test button.
IF you DO NOT SEE a test button, it is because it is part of a fire alarm system, and you as an HI should not attempt to test it.
Lastly
Testing with smoke
Smoke DETECTORS (and smoke alarms) that are part of a fire alarm system, yes, these should be tested with smoke or canned smoke. BUT you, as an HI, are not qualified (trained, licensed) to perform testing on fire alarm system (or any component of it).
Smoke ALARMS (like those you can get at HD or Lowes).
Should NOT be tested using smoke or canned smoke.
Because using smoke or canned smoke can contaminate the detection chamber, thus damaging the unit.
After testing with smoke (or canned smoke) the unit is to be disassembled and cleaned.
Smoke DETECTORS and Smoke ALARMS that are part of a fire alarm system, can be disassembled for cleaning. Ordinary smoke ALARMS like you get at HD or Lowes may not be able to be disassembled for cleaning.
Testing with smoke or canned smoke, how much smoke do you use?
How long do you spray the can?
Just as with Duane who said 80% did not work using canned smoke. Testing with canned smoke should be done by trained and qualified personnel. Otherwise you may get results that are unreliable.
As for the IRC referencing NFPA 72
Yes it does. It's talking about FIRE ALARM SYSTEMS.
For smoke alarms NFPA 72 requirements are for placement (bedrooms, each level...).
For testing smoke alarms, NFPA 72 says follow the manufacturers instructions. The manufacturers instruction say to press the test button. There is nothing in the instructions about using smoke. Pressing the test button is a calibrated sensitivity test. You are correct that pressing the test button does not test for entry of smoke into the smoke chamber. For that reason, the manufacturer recommends to vacuum the smoke alarm. Vacuuming the alarm helps to insure that nothing blocks the entry of smoke into the smoke chamber.
Remember, there is a higher level of reliability placed on smoke DETECTORS for a fire alarm system, than there is on ordinary smoke ALARMS. That is why smoke DETECTORS connected to a fire alarm system are required to be tested with smoke and smoke ALARMS are not required to be tested with smoke.

Re: smoke & Co alarms
I'll try
When a fire alarm company installs a fire alarm system in a house the number and location of smoke detection devices must be at least as good as what is required for smoke ALARMS (such as those you get at HD).
The company installing the fire alarm cannot install a single smoke detector and call it a fire alarm system, unless the house has a combined total of smoke DETECTORS and smoke ALARMS that meet the number and placement requirements.
Example
A house has existing smoke ALARMS installed in the bedrooms, and on every level... as required (number and placement).
An alarm company CAN install a Single smoke detector and call it a fire alarm system. In this case the existing smoke alarms count toward meeting the number and placement requirements of NFPA 72. Note, since the alarm company is using the existing smoke alarms toward meeting the requirements, they must now test the existing smoke alarms just like the requirements for testing the smoke detectors of a fire alarm system. This DOES INCLUDE testing with smoke.
If the house has existing smoke alarms that meet the number and placement requirements, and the company installs smoke detectors along with the existing smoke alarms (1 for 1). The existing smoke detectors are redundant. Therefore the company does not need to rely on the existing smoke alarms and DO NOT need to test them. The company would only need to test the smoke detectors they installed.
If a house has no smoke alarms installed ( or to few to meet the requirements for number and placement), the company must install as many smoke detectors as needed so that the total meet the requirements for number and placement.
"Where a household fire warning system is installed using a combination of smoke detector and audible notification device(s), it shall become a permanent fixture of the occupancy and owned by the homeowner. The system shall be monitored by an approved supervising station and be maintained in accordance with NFPA 72. "
What this is saying
A few years ago, some companies would "LEASE" a burglar and fire alarm.
As long as the customer paid the monitoring fee every month, all was good.
Some customers decided to cancel the monitoring. The company would then come out and remove the equipment. Leaving holes in the walls, and leaving the customer with less than what is required (number and placement) of smoke alarms. Now, the equipment is considered a permanent fixture of the house and the company is not allowed to remove it.
I may not have described that very well, if not I'll try again.
I hope you accept my apologizes for saying you are an "Idiot" and a "Fool"
I am certain your IQ far exceeds that of an Idiot.
As for a fool, it is neither my place nor right to describe you as a fool.
