KY-04 electronic lock controller

General use

The easy to use electronic keys only need a brief contact with a specially designed brass or stainless steel contact. The number stored in the electronic key is compared with the keys stored in internal non-volatile memory. If a match is found, the lock wil open for two seconds. Keys are easily added to and removed from the non-volatile memory using the 'Master key'.

A ky-04 unit
Connecting Wiring schemes for connecting the KY-04 unit to the lock, power and KK-01 key contacts are available for the KY-04s and the KY-04d.
Master key The first key to make contact will be made the master key. The subsequent initialization of the non-volatile memory can take up to 8 seconds. The system can be cleared again by holding the master key against a contact for 10 seconds. This erases the non-volatile memory: as before, the first key to make contact will be made the master key.
Always appoint a new master key at once!
Adding a key To add a user key you should - within a two-second period - hold the master key, the user key and the master key again to a contact.
Deleting a key To delete a user key you should - within a two-second period - hold the master key, the user key and the master key again to a contact. All keys can be deleted at once by initialising the lock (see "Master key").
Contact There are weather proof black delrin, elegant brass and stainless steel versions of the contact in multiple sizes. More contacts can be used with the same controller, eg. on both sides of a door.
RS-232 The KY-04 can be equipped with a RS-232 communication interface. This interface enables data logging and direct control with your PC or any device with a RS-232 interface. The specifications for RS-232 communications with the KY-04 can be found here. The KY-04 can also be controlled over the RS-232 using the Key4win key management software.
