R4 Electric strike 24V DC - reverse action 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

Reverse action version - or the so-called reverse lock. In its volt-free condition, the lock is unblocked. As soon as voltage is fed to it, the lock`s lever blocks the ratchet. This version is mainly used in general use areas, where fire-fighting and work health and safety regulations impose the condition that the door must be unblocked in voltage drop situations, e.g. at schools, cinemas, office areas, etc.

DC - after connect to DC electric strike gives out no noise at all.

AC - connecting to AC will generate continued low humming noise. Low humming noise is canceled after connecting the rectifier - available separately.
