Smoke detectors PH-WYG apply to some place where is less smoke or stop smoke to probe smoke ion. They can probe smoke exactly by 168 A. The detector will send out sound&light to alarm and send the alarm message if the density of smoke exceeds limitation.

Specification
Voltage: 12V DC
Current consumption: Less than 10uA in idle mode, 10 to 30 mA while alarm.
Frequency: 315MHz or 433MHz(optional)
Sensitivity of smoke: Accord with UL NO. 217 standard
Operational temperature: -5º C to 50º C
Humidity: 10% to 90%
Intensity of buzzer' volume: 85 decibel 10 foots

Installation
There is a manual of PH-WYG, a detector and two screws in the packing. Choose the suitable position to fix the bottom with screws, and then fix the cover and push-button according to sketch map. About 25 to 40 square meters in the room, there should be a smoke detector. If there is some important equipment, we suggest that you should install a detector about 0.5 to 2.5 meters.

Notice
The smoke detector PH-WYG should not be install in the areas where is high temperature and high wind velocity. In order to keep the detector efficient working, you should clean it 6 months each time. Turn off the power at first, just sweep dust with soft brush. Then turn on the power.
