You can use more than 8 different types of key functions
You. The following different types of keys may be programmed: Key type A: open and not open, and sequence
Normal operation for sensors or non-sequences;
Is the master key level and all other key types
Operates in this manner except for the special features already described. Key type B: One entry "one shot". Once

The ban feature is true and locks are deadbolted
If the maid key is inserted for the first time,
The indicator is started. Key Type F: Emergency / Rephase. This is the most advanced security
Is a cheap key, the key is inserted and the knob is turned
If not, assert logical deadbolt status. Open
Spiders are designated as emergency keys and are always
Open doors regardless of logical deadbolt status
Good. By inserting the key and turning the doorknob,
The deadbolt is released. What this key does not open
Is indicated as a rephase key. Insert this key
This asserts a logical deadbolt, but the knob

Is required to prohibit the use of this level. Key Type G, Security A: This key is 2 for advanced security
The first of a key sequence. What opens is logical
He asserts that he does not open.
This ensures that new locks are not created without deadbolting the lock.
Enables a cheap key sequence. Key type H, Security B: This key is for advanced security
This is the second of a two-key sequence. This key is
