SBL350.SFR Fire Rated Push Button Digital Lock with Knob and Key Override

The SBL350.SFR is a compact and self contained fire rated mechanical digital coded lock with a knob and key override, supplied complete with a 60mm backset deadlocking tubular latch. The digital lock is robust and gives a convenient means of providing security for low to medium traffic areas such as storerooms, workshops, plant rooms and offices.

The SBL350 allows entry either via the code or with one of the keys supplied with the unit. The internal unit provides safe egress by a large turn knob.

Conventional detainers are rearranged to change the code.

The key override allows entry without the code, useful in an emergency or as an alternative to code access.
