INSTALLATION
AR-2808 ASSEMBLY
Precautions for Installation Location
The EM Card works at the frequency of 125Khz. Installation precautions are necessary:
F
i) Make sure the location has no strong low frequency electro-magnetic wave signals near it.
IIIIII
Especially in the range of 100-200Khz.
F
ii) If more than one keypads / readers operating in the same frequency, make sure that they are at
IIIIII
least 60cm (2ft) apart from each other. Otherwise, the reading range may be reduced due to
IIIIII
interference.
Precautions for Accidental Short Circuit
In the previous experience, most of the damages caused during installation are accidental touch of
the components on the circuit board with the wire(s) carrying power. The following precautions are
necessary:
F
i) Study the manual thoroughly to become familiar with the system before installation.
F
ii) Do Not apply power to any connection terminal of the reader during installation.
F
iii) Check all the wirings carefully and confirm that they are correct before applying power to the
F13I
reader for testing.
Precautions for Electric Spikes & Back EMF
Make sure to connect the diode (supplied) or a varistor (MOV) across the electric lock’s power input
terminals to absorb the back EMF and the electric spikes. Fail to do so may cause damage to the
electronic components; in worst case, even burn out the reader.

1) Stand Alone Access Control Electric Lock
NOTE:
●
Connect the 1N4004 as close as possible to the lock in parallel with the power terminals of the lock to absorb
....
the back EMF to prevent it from damaging the reader. The 1N4004 is not required if the electric lock is AC
....
operated.
●
To aviod Electro-Static-Discharge from interfering with the operation of the reader, always ground the (-) terminal

The tamper switch is Normally Closed while the
reader is secured on box. It is open when the
reader is removed from box. To give alert on
sabotage, connect these terminals in series with a
24 hour N.C. protection zone of an alarm system if
required.
