Mounting instructions for double-bit high security
locks S2700U and S4700U
The lock is designed for use with a metal secure-storage unit and has to be mounted
using screws size 6, strength category 8.8, length 35 mm. The tightening torque applied
to tighten the bolts must not exceed 10 Nm. Apply a liquid screws tightening agent to
stop the screws becoming loose. The lock can be mounted either horizontally, with the
bolt pointing to the right or left, or vertically, with the bolt pointing up or down.
The illustration above shows the lock dimensions.
There are two possibilities to release or operate the bolt mechanism of the lock:
1. Bolted-on bolt work mechanism: the bolt work mechanism is screwed to the
front of the lock bolt using screws size M4 or M5
With this method, the bolt work is operated by means of the lock.
2. The bolt work mechanism is not screwed on: With this method, the lock only
Allows the lock bolt to move freely. In other words, the bolt work is operated
separately.

- When mounting the lock, please take the necessary precautions, eg. by installing a
manganese plate, to make sure the lock is adequately protected against
forceful attack. We further recommend to secure the bolt work cover on the
back of the door with a small lock to prevent direct access to the lock whenever
the door is open.
- As a rule, the lock is opened clockwise and closed anti-clockwise.
- It is also possible to mount the locks so that the keys have to be entered from above or
below.
- After entering the key in the mounted lock, be careful not to put too much pressure on
the key from the side (risk of key breakage).
- Do not lubricate the lock with oil or grease.
- Prevent welding beads and similar dirt from getting into the lock.

Bolt strength in accordance with VdS 2396
for lock types S2700U and S4700U:
Under normal conditions ofuse, the maximum permissible
forces acting onthe bolt in both directions (push and pull)
amount to 5 N. This force may be safely applied for at least
10,000 cycles.
