Electric power industry smoke is suitable for shopping malls, hotels, shops, warehouses, and other civil and industrial electrical room place fire pre-alarm. Detector with high sensitivity, stable and reliable, low power consumption, beautiful and durable, convenient use, etc, can be used with security systems.
The performance characteristics of
New type of high performance sensor can effectively detect smoldering fire
Networking alarm intelligent microprocessor, a variety of fire model algorithm to eliminate false alarms, passive relay contact output can be set up
Networking alarm with wide voltage design, convenient for engineering applications
The smoke chamber adopts insect nets design, avoid insects go call the police
Leds - display alarm work normally and alarm status
The shell adopts fireproof ABS engineering plastics, the beauty is generous
The performance parameters
Power supply: DC9V ~ DC28V.
Electricity flow, static current ua 200 or less; Alarm current 45 ma or less.
Working temperature: - 10 ℃ ~ + 50 ℃.
Relative humidity: 95% RH or less (40 ℃ + 2 ℃).
Alarm sounds: 80 db/m or higher.
Output format: passive relay contact output can be set to (NO/NC), contact capacity 1 a / 24 VDC, the factory default output is normally closed.
Smoke sensitivity: 0.15 ~ 0.3 dB/m.
Temperature alarm Settings: 57 ~ 62 ℃.
function
Work: under normal circumstances, the probe about every 5 to 6 seconds will shine. Detector automatic detection of smoke concentration and temperature of the surrounding environment changes, and according to the use of environmental sensitivity automatically compensate. When the smoke concentration or temperature alarm value, close to the probe to speed up the smoke concentration or temperature trend of intelligent computing, at the same time, the alarm light began to shine. If the operation result reach or exceed alarm value, detector keep normally on red LED lights, sound, and start the relay output. When the smoke in the environment or the temperature returned to normal, the detector automatically return to normal working condition.
Note: the detector alarm, passive output relay contacts, contact capacity of 1 a / 24 VDC, through the probe on the PCB jumpers, set to normally open or normally closed contact output. To jump line factory default Settings for the normally closed contacts.
The installation
Probe the base of the installation size of 47 cm - 88 cm. When installation, on the ceiling are 60 mm apart on the location of the two mounting hole 5 mm in diameter, with a new plug screw and detector base on the ceiling. Connect the power cord on the base of terminal 2, terminal 6 (nonpolar), passive relay contact output lines connected to the base terminal 3, terminal 5. Button will probe in the right direction on the base, press down the screw clockwise. It starts working just by turning on the power supply.
Pay attention to
Smoke detector and smoke temperature compound detector is not appropriate to use in the following places:
Under normal circumstances have smoke retention of place
Have larger dust, water, steam, oil mist pollution,
The place of corrosive gases
Ventilation speed greater than 5 m/SEC
Relative humidity is more than 95%
Thermal detector and smoke temperature compound detector is not appropriate to use in the following places:
Normally high temperature place for a long time
Failure analysis and elimination
Alarm without output: check the jumper Settings are correct.
Frequent false alarms: possible sensor maze caused too much dust, vacuum cleaning maze (outside the black plastic part)
maintenance
In use process, if the use of failure, please contact the supplier as soon as possible, don´t remove the repair secretly, in order to avoid accidents. If not use for a long time, must remove the detector, in packaging, store in ventilated dry place.
Transportation and storage
According to GB/T15464-1995 "instrumentation packaging general technical conditions" regulation for transportation and storage.
Transport storage must keep the plants in the process of the original packaging and seal integrity, and to ensure that products from severe impact.
Environment temperature should avoid violent change.
The stacked height less than 6 layer, using the split open a case after the single height stacked no more than five layer.
