INSTALLATION
HAA2866
PRECAUTIONS
1) Prevent Interference:
The EM Card reader is working at the frequency of 125Khz. Installation precautions are necessary.
i) Make sure the location for installation has no strong low frequency electro-magnetic wave signals.
Especially in the range of 100-200Khz
ii) If there is more than one keypads with the same operation frequency installed closely in the same
location, make sure that they are at least 60cm (2ft) apart from each other to prevention interference.
2) Prevent Accidental Short Circuit:
In the previous experience, most of the damages caused in the installation are accidental touching
of the components on circuit board with the wires carrying power. Please be patient to study the
manual to become familiar with the specifications of the system before starting the installations.
i) Do not apply power to the system while it is in installation.
ii) Check carefully all the wirings are correct before applying power to the system for testing.
