New high-performance sensor can effectively detect smoldering fires occurred
Network alarm intelligent microprocessor , a variety of fire model algorithm to eliminate false alarms , relay contact output can be set to passive
Network alarm with wide voltage design , engineering applications easy
Smoke chamber using insect nets designed to avoid insect straying alarm
LED lights - displays alarms and alarm status to work
Shell is made of fireproof ABS plastic , nice
Performance parameters :
A performance:
Power supply : DC9V ~ DC28V
Current: ≤ 200uA quiescent current
Alarm current ≤ 45mA
Working temperature : -10 ℃ ~ +50 ℃
Relative humidity : ≤ 95% RH (40 ℃ ± 2 ℃)
Audible alarm : ≥ 80dB / m
Output Type : Passive relay contacts (NO / NC can be set ) output , contact capacity 1A/24VDC,
The factory default output is normally closed mode .
Smoke sensitivity : 0.15 ~ 0.3dB / m
Temperature alarm settings : 57 ~ 62 ℃
Second function:
Work: Under normal circumstances, about 5-6 seconds, the detector light will flash about every . Detector automatically detects the surrounding environment of the smoke concentration and temperature changes , and the sensitivity of automatic compensation based on the use of the environment . When the smoke density or temperature close to the alarm, smoke detectors accelerate the concentration or temperature trend for intelligent computing, while warning light starts flashing. If the calculation results meet or exceed the alarm value , the detector remains lit red LED lights , audible, and start relay output.
When the smoke in the environment or the temperature returns to a normal state , the detector automatically restored to normal working condition.
Note: The detector alarm, passive contact output relay contact capacity 1A/24VDC, jumpers probe by the PCB , is set to normally open or normally closed contact output. The factory default setting jumpers normally closed contacts .
Three installation:
Detectors installed base size is 42cm-75cm. When installed on the ceiling of 5mm apart hit two 60mm diameter mounting hole positions , as shown in the ceiling rose 3 with plug and screw the detector base .
Note:
1 smoke detectors and smoke detectors unsuitable temperature composite use in the following places :
There are places smoke retention under normal circumstances l
l have a greater dust, mist , steam, oil mist pollution,
Place corrosive gases
l air velocity greater than 5m / s in place
l relative humidity greater than 95% more
(2) heat detectors and smoke detectors unsuitable temperature composite use in the following places :
Under normal circumstances, the place of long-term high temperature
Four wiring:
Connect the power cord to the base terminals 3 , 4 on the ( non-polar ) terminals , passive relay contact output line is connected to the base terminal 1 and terminal 2. The buckle in the right direction by the detector on the base, the tightening pressure in the clockwise direction . Power to work .
V. Failure Analysis and Troubleshooting
1 Alarm No output : Check the jumper settings are correct.
(2) frequent false alarms : Possible sensor maze caused by too much dust , use a vacuum cleaner to clean the maze ( outer black plastic part )
VI. Maintenance
During use , such as the use of fault encountered , please contact your supplier as soon as possible , do not dismantle repair , to avoid accidents.
If long-term use , the detector must be removed , into the box , stored in a dry place .
VII. Transport and storage
Transport and storage in accordance with the provisions of GB/T15464-1995 " General Instrument Package technical conditions" .
Transportation must be maintained during storage factory original packaging and seal integrity , and to ensure that the product is not subject to severe shocks.
Avoid dramatic changes in environmental temperature .
Packing stack height does not exceed six layers stacked height after unpacking single piece does not exceed 5 layers.
