Smoke Detector 928N
An ISO 9001:2015, certified Company established in 1998 at Ningbo is rapidly expanding manufacturer offering a wide range of smoke alarm,smoke detector support in the field of Design,Engineering,Manufacturing.
The product is a new type of photoelectric smoke detector, When it detects smoke twice,it will output signal immediately and trigger connected unit to work,which tell you in advance that fire will occurs and avoid unwanted loss,and take you safety and convenience.
WHERE NOT TO INSTALL SMOKE DETECTOR
1. Where combustion are permitted to produce. For example unventilated kitchens, garages, and furnace;
2. near fanner;
3. In very damp, humid or steamy areas: Keep units at least 3m away from showers saunas, dishwashers, etc.
4. In very dusty, dirty, or greasy areas;
5. In very drafty areas, where smoke will be blown away from the unit completely,
6. in air-logged areas, that will clog the sensing chamber;
7. Less than 305mm away from fluorescent lights. Electrical “noise” can interfere with the sensor.
8. In “dead air” space, for example, in Diagram 1, near the corner less than 10cm.
9. in smoking meeting room, don’t install the alarm there for the unit will alarm when several persons smoke.
The detector must be tested after installation and maintenance cleaning.
Note: Before the test, the relevant management department smoke detector system will be notified for maintenance and therefore will stop working. Cut off the logic control kinetic energy of the area or system that will be maintained to avoid unnecessary alarm linkage. Make sure the detector is wired correctly and power the system.
Then test it as follows;
1. Switch the power, the indicator should flash once every 30 seconds.
2. Press the test pin (less than 1.5mm in diameter) into the hole for about 2-3 seconds, and the indicator should always be lit.
3. If the indicator does not light, please check if the test pin is used correctly .
4. Smoke test: Take a smoldering wooden stick or cotton core on the side of the detector and blow the smoke into the detector until the alarm.
Warning: Due to the above test, the detector can only be reset after the power supply is momentarily powered off.
If the detector fails the above test, check that the wiring is correct.
