R4 Electric strike 12V DC - memory version, lowered current consumption version

Note

The R4 Electric Strike is designed for remote opening of door and gates left- and right side and double-wing ones. It works together with ratchet-latch or ratchet type door lock.
The advantage of this catch is its small dimensions and its symmetrical design thanks to which the version can be mounted both to left- and right side door. The additional advantage is the increased reliability of operation in case of twisted doorframe or distorted door.

They are made of rust proof zinc alloys, so they can be installed outside buildings, however in such case they should be protected against flooding, hostile weather impacts and against accidental coating by paint.
Additional plate is required for mounting.

Electric strike version

The interlock version - acts in the same way as the basic version, but has an additional ratchet interlock function, thanks to which, when the interlock lever is moved, the door is left open permanently, without the use of an electronic pulse. When the interlock lever is moved back to its original position, the lock works as in the basic version.
This version may be used in rooms, where temporary unblocking of the door may be sometimes needed within working hours, i.e.: in office or services areas. When working hours are over, it is possible to block the lock again, whereby access to the premises is controlled by means of an interphone set system.

Lowered current consumption version - features a unique coil design, which allows the lock to work under voltage continuously.
This version may also work as the basic version. It does not interfere with the work of electronic interphone systems.

DC - designed for direct current (DC) only.
