The sensor can be tested in the following ways:
A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)
This sensor can be functionally tested with a test magnet. The test magnet
electronically simulates smoke in the sensing chamber, testing the sensor
electronics and connections to the control panel.
1. Hold the test magnet in the magnet test area as shown in Figure 3.
2. The sensor should alarm the panel.
Two LEDs on the sensor are controlled by the panel to indicate sensor
status. Coded signals, transmitted from the panel, can cause the LEDs to
blink, latch on, or latch off. Refer to the control panel technical documen-
tation for sensor LED status operation and expected delay to alarm.
B. Smoke Entry
Sensitivity readings are available through the FACP. Refer to the manufac-
turer’s published instructions for proper use.
Additionally, canned aerosol simulated smoke (canned smoke agent) may
be used for smoke entry testing of the smoke detector. Tested and ap-
proved aerosol smoke products are:
Manufacturer Model
HSI Fire & Safety 25S, 30S (PURCHECK)
SDi SMOKE CENTURIAN, SOLO A10,
SMOKESABRE, TRUTEST
No Climb TESTIFIRE 2000
When used properly, the canned smoke agent will cause the smoke detector
to go into alarm. Refer to the manufacturer’s published instructions for proper
use of the canned smoke agent.
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse of these products may have long term ad-
verse effects on the smoke detector. Consult the canned smoke agent manufac-
turer’s published instructions for any further warnings or caution statements.
C. Direct Heat Method (Hair dryer of 1000-1500 watts).
A hair dryer of 1000-1500 watts should be used to test the thermistors. Di-
rect the heat toward either of the two thermistors, holding the heat source
approximately 12 inches (30 cm) from the detector in order to avoid dam-
aging the plastic housing. The detector will reset only after it has had suf-
ficient time to cool. Make sure both thermistors are tested individually.
D. Multi-Criteria Method.
A Testifire® by SDi provides testing of the smoke and heat sensors. Consult
the manufacturer’s published instructions for complete instructions.
A sensor that fails any of these tests may need to be cleaned as described
under CLEANING, and retested.
When testing is complete, restore the system to normal operation and notify
the proper authorities that the system is back in operation.
CLEANING
Before removing the detector, notify the proper authorities that the smoke
detector system is undergoing maintenance and will be temporarily out of
service. Disable the zone or system undergoing maintenance to prevent un-
wanted alarms.
1. Remove the sensor to be cleaned from the system.
2. Remove the sensor cover by pressing firmly on each of the four removal
tabs that hold the cover in place.
3. Vacuum the screen carefully without removing it. If further cleaning is
required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or compressed air to remove dust and debris from
the sensing chamber.
6. Reinstall the chamber cover/screen assembly by sliding the edge over the
sensing chamber. Turn until it is firmly in place.
7. Replace the cover using the LEDs to align the cover and then gently push-
ing it until it locks into place. Make sure that the thermistors do not be-
come bent under the cover.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.
SPECIAL NOTE REGARDING SMOKE DETECTOR GUARDS
Smoke detectors are not to be used with detector guards unless the combina-
tion has been evaluated and found suitable for that purpose.

SPECIAL APPLICATION
When configured at the fire alarm control panel, this detector is capable of op-
erating in a special application mode such that it has a higher sensitivity than
is normally allowed by UL 268 for areas where early warning is important. In
this mode, the detector does not comply with the Cooking Nuisance Smoke
Test. Detectors (Sampling ports) set to the special application mode are not
suitable for use in areas where cooking appliances may be used. If cooking
appliances are used within the protected space, a normal application detector
or normal application mode must be used for that area.
Special application mode is not for general use and the detector may be more
prone to false alarms if used in unsuitable environments. While no list is
all-inclusive, some examples of unsuitable environments for special applica-
tion mode are areas with airborne particulate or aerosols including sawing,
drilling, and grinding operations, textile or agricultural processing, or areas
with engines that are not vented to the outside. A complete list of aerosol and
particulate sources is available in the Annex of NFPA 72.
Suitable environments for special application mode could include early warn-
ing for hospitals, museums, assisted living and other areas that do not have
airborne particulate or aerosols.
Refer to the fire alarm control panel documentation for information on how to
configure the detector for special application mode.
