Mount the backplate using countersunk headed screws adjacent to the opening
edge of the door and at a convenient height (recommended height is 5' (1.5m)
to top of unit).
If fixing hole ’A’ is used then the breakout must be removed and the screw must
not protrude.
Feed the cable from the controller through the backplate.
If the wall tamper function is to be used then the small hole in breakout ‘B’ may
be used to mark the position of the wall screw before the breakout is removed.
An appropriate wall screw should then be adjusted in height to protrude through
the hole to activate the tamper lever.
The securing screw ‘C’ is integral to the backplate and is unscrewed via the small hole in the enclosure so that the
screw head locates in the counterbored holes on the inside of the enclosure.

Present the card face-on to the reader until you hear a"bleep". Cards can be presented in rapid succession; there is no need, for
example, to wait for "GREEN LED’s" to disappear before presenting another.
If the reader has been enabled for user-code mode at the controller, you can gain access by pressing the O key, entering your
card number, then pressing the P key.
GREEN – The lock is released and you may open the door.
RED – You do not have access rights to gain entry, or the reader did not read your card properly (in this case, present it again).
YELLOW – Enter your PIN. If you make a mistake, the RED LED’s are momentarily displayed, followed by YELLOW LED’s,
to prompt you to try again.
