Symmetrical fail safe strike kit, 24Vdc

Ref: F0502000020-B

The S Series of electric strikes are constructed in robust stainless steel. The symmetrical body of the strike makes installations easier and reduces the overall dimensions of the unit.

As one of the smallest and narrowest strikes available, the SIR-24 is suitable for UPVC doors as well as multipoint locking. This model is fail safe, features a radial jaw, and comes with a fixing plate as standard.

The MOV (metal oxide varistor) fitted inside all S Series strikes protects your system from electric spikes that can cause damage to electronic control devices.

(Note: Since acquiring JIS, we are in a transition period of strike versions. The first photo shows the previously sold strike and the second photo shows the new version. Nothing changes to the strike specifications.)
