13.1 Leaving
the
premises
The RF30-EM’s mechanical locking device only affects the outside door handle.
The door can always be opened from the inside as usual.
13.2 Automatic
resetting
RF30-EM has two separate resetting systems to return the lock to the locked
position after a code has been entered. The lock is reset mechanically each time
the door handle is used during access. The lock is also electronically reset if the
handle is not used within 4 seconds after a card is used or a code being entered.
This provides security against unauthorised access, since the RF30-EM can never
accidentally be left in the unlocked position.
13.3 Access
blocking
To thwart attempts to obtain an access code by trial and error, RF30-EM
incorporates a blocking function to disable the unit after 12 false key presses (three
successive incorrect 4-digit codes). The unit remains blocked until 2 correct codes
are entered successively.
13.4 Backup
power
supply
When the batteries are running low. RF30-EM will flash the red LED for 3 seconds
before opening the lock. The lock has a backup power supply that will allow the
door to be opened 200 times or a time of two weeks has passed.
After the door has been opened 200 times the only way to open the door is with the
Administrator code.
