SMOKE DETECTOR TESTING
Measure and record test voltage at test points
RP1 & RP2. If the product is operating
normally, and was cleaned effectively, the test
voltage will be less than the voltage recorded
earlier. (Typical voltage for a clean device is.9
- 1.58 Vdc.)

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.
DORMA 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 read as first numeral = last
digit of year so that a B0xxx = 1990 and B9xxx = 1989.)
3. in accordance with the instructions stated above.
If the preceding requirements are not met, the use of Smoke Detector Tester is unacceptable and
DORMA cannot 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.
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.

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.
