Cellphone Signal Detector/Mobile Phone Detector/Signal Detector

I. Introduction
This Cellphone signal detector can detect the cellphone signal of CDMA, GSM, DCS, PHS & 3G.
The detector detects the cellphone signal, then it will output high level signals and
communication signals. The high level signals will be output to the annunciator which
controlled by the numerical control box, the cellphone signal or the surveillant equipment.
The communication signals will be transported to the computers mainunit, and registered
the correlative message in the computer for memory.
 
II. Technical parameters
TX Frequency
a.RX Frequency : 824MHz ~ 849MHz (CDMA)
b.RX Frequency : 890MHz ~ 915MHz (GSM)
c. RX Frequency : 1710MHz ~ 1785MHz (DCS)
d. RX Frequency : 1920MHz ~ 1980MHz (PHS & 3G)

 Each frequency band has a corresponding antenna, so there are 4 antennas on the equipment.
Jamming range of the signal detector : 5-20M (It still depends on the strength signal in given area)
The green light on means the main system work well, the red light on shows that the RF inspecting
  system works well.
When the detector is working, the TTL signal and RS-485 communication signal are output by the system.
Sentivity of the signal detector : Adjusted knobs, independent frequency.
Caboodle Management : coding orientation
Temperature : -40°C~ 55°C
Receiving Antenna : Plastic antennas
Working Voltage : Input AC 110V ~ 240V  50/60 Hz
                             Output DC 5V  2A
Dimension : 230*85*30mm
Working Time : It can work stably for a long time
Environment Temperature : -20°C ~ 65°C
Relative humility : 30% ~ 70%
 
III. Installation and operation instruction
  3.1 Take out the detector from the packaging.
  3.2 Screw the antennas into the corresponding antennas seats repectivelt, otherwise they will be useless.
  3.3 Hang the detector onto the wall. (Setting height ≥2M)
  3.4 Insert the AC plug into the socket, then switch on. When  the power indicator is lit, it means that the device starts working. (Different detector should be with different battery.)
 
IV. Working Area
  4.1 It can be used to the place which the cellpnone was forbidden.
  4.2 It is also can used in a shielded place which makes up with the detector and isolator to prevent  using cellphone.
