2) Smoke entry test
The Trutest model 300 Aerosol Smoke Detector Tester can be
used for smoke entry testing. Set the generator to represent 4%/ft
to 5%/ft obscuration as described in the Trutest manual. Using the
bowl shaped applicator, apply aerosol until the panel alarms.
Additionally, canned aerosol simulated smoke (canned smoke
agent) may be used for smoke entry testing of the smoke detector.
Recommended aerosol smoke products are:
Manufacturer
Model
Trutest
AERO400
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.
Warning:
Canned aerosol simulated smoke (canned smoke
agent) formulas will vary by manufacturer. Misuse or overuse of
these products may have long term adverse effects on the
smoke
detector.
Consult
the
canned
smoke
agent
manufacturer’s published instructions for any further warnings or
caution statements.
3) Temperature rise test
Approach a heater (such as a hair drier of 1000w-1500w) to the
thermistor of the detector until it alarms. It is 12 inches between the
hair drier and the thermistor to avoid damaging on the plastic
enclosure of the detector
If a detector fails in testing, replace it. After testing, reset the
detector. Notify the proper authorities that the system is back to
normal operation.
Maintenance
Clean the detectors regularly, at least once a year to ensure
normal operation of the system.
If unwanted alarms are often found of the detector on site, the
sensing chamber should be cleaned. Power must be removed
from the detector before cleaning.
Steps for chamber cleaning:
a)
Open the top cover of detector, and draw out the sensing
chamber by slightly lifting its two sides using a straight
screwdriver, as shown in Fig.6.
Fig. 6
b)
Use a vacuum cleaner or cleaned, compressed air to
remove dust and debris from the insect guard and the
sensing chamber. The sensing chamber can also be
cleaned by clear water and brush. Put the sensing
chamber in clean water to brush the dust inside and take
out to dry it.
c)
Put back the chamber and the top cover.
Cautions
1. Dust covers can
’t be removed until the project is put into use
formally. Take well care of dust covers for future use.
2. Dust covers effectively but not absolutely prevent dust
particles from going into detectors. So, we recommend that
detectors should be removed prior to construction, decoration, or
other activities producing dust. The proper authority should be
informed of detectors removing.
3. Be careful not to damage the detector in maintenance.
4. The smoke detector may not sense fire that where smoke
cannot reach it, such as in chimneys, in walls, on roofs, or on the
other side of closed doors.
5. The detector cannot monitor the place beyond protection area.
6. The detector may not warn you about fires caused by
insufficient safety measures, violent explosions, leaking gas,
improper storage of flammable materials like diluents and other
safety hazards, arson or children playing with fire.
7. The alarm of a smoke detector used in high velocity
environment will be delayed due to dilution of smoke by frequent
and fast airflow.
8. The smoke detector cannot last forever. In order to keep the
detector working in good condition, please maintain the equipment
continuously according to recommendations from manufacturers
and relative state standards.
9. The detectors must be tested regularly, at least once a year.
10. The base should be fastened and the wire should be connected
reliably.
11. Fire LED of the detector should face the main entrance where
people can watch it easily.
12. Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suitable for
that purpose.
