5.5 Smoke detector testing
Fig.33
Point the Smoke Detector Tester tube at the detector and release a burst of aerosol by depressing the nozzle for
1 second. Give the detector sufficient time to respond. This may be up to 20 seconds.
If the detector is in an area where air velocities exceed 100 feet/minute, the detector may not alarm on the first
try. This could be due to the signal processing feature of the detector. Signal processing is a feature that adds a
time delay to each detector which effectively increases its stability. If this is the case, spray in repeated bursts of
1 second at approximately 5 to 10 second intervals. The total number of sprays should not exceed five (5). If the
detector does not alarm after 5 consecutive sprays, it will be necessary to generate larger volumes of smoke to
overcome the air flow dilution factor. This can be accomplished by burning paper or fabric in a metal can.
dormakaba accepts the use of Home Safeguard Smoke Detector Tester (Models 1H and 25S) if, and only if, it is
used:
1.
with the Model 1490 Accessory.
2.
with the new formula aerosol as identified by a date code, located on the bottom of the can, of 1990 or
later. (This date code can be as first numeral = last digit of year so that a B0xxx = 1990 and B9xxx = 1989.)
3.
in accordance with the instruction stated above.
If the preceding requires are not met, the use of Smoke Detector Tester is unacceptable and dormakaba can’t
guarantee the proper operation of detectors that have been subjected to this product.
Alternative methods of generating smoke/aerosol such as the Gemini 501 Smoke Generator Machine may be
used to cause alarm at the detector’s installed location. Set the generator to represent a 4%/ft to 5%/ft
obscuration as described in the Gemini 501 Manual and apply aerosol until the unit alarms. If the Gemini unit is
not available, cigarette, punk, or cotton wick are also acceptable means of generating smoke to test this
detector.
REMEMBER:
Aerosol testing is only a “go - no go” test and is not an acceptable means to determine the smoke detector’s
sensitivity. See NFPA 72E.
