3.2 Installation Notice
1. Single door controller locate inside the secure area for use as an
exit controller, the auxiliary reader locate exterior wall for use as
an entrance reader, but not directly behind single door controller.
For best reading distance, offset the single door controller and
auxiliary reader by about 50 cm above and 12 m below
(suggestion value).
2. Normally, single door controller will read a Card / Key Tag at up
to 15 cm. However, when single door controller or optional

wood or plastic between the mounting surface and mounting
plate, this will restore most of the reading distance.
