New Latch lock


Mechatronics meets Safety

With the HSL 103, STUV presents the first latch lock with mechatronically engageable rotary knob and the proven HSL locking mechanism.

The HSL 103 can be used in detention rooms as well as in passage doors. The high-security lock is powered by a continuous current source or a battery.

The latch bolt is operated either purely mechanically by means of an HSL double-bit key or via a rotary knob / lever handle which is activated by a coupling mechanism. When the coupling mechanism is deactivated, the rotary knob is in free idle. The coupling mechanism is controlled either via encrypted security RFID ident media (card/chip) locally via wall reader or outside module and/or via external control signals. The coupling mechanism can optionally be activated via a separate occupant button or a cell call terminal.

The Open Security Standards Standard Offline (OSS-SO) allows the use of different ident media and thus easy integration into existing access control systems.

The mechanical locking mechanism is superordinate to the electronic coupling mechanism, i.e. even in the event of a power failure or technical malfunction of the control system, the HSL 103 can be fully operated by means of the HSL double-bit key.

If the locking mechanism is in the night lock position, it is not possible to activate the coupling mechanism and operate the latch bolt by means of the rotary knob.

The latch bolt can only be operated by means of the coupling mechanism and the rotary knob after release by the 1st tour.

If the lock is opened mechanically with the HSL double-bit key (2nd turn, recoding position), locking the latch bolt with the knob and coupling mechanism is also not possible.  In this position, the mechanical locking mechanism can be recoded to another locking as usual.

Knob activation via RFID-Ident medium

The RFID-Ident medium is read via wall reader or an outside module on the inside and/or outside of the passage door. The read-in data is transmitted to the evaluation and control unit in the lock and compared with the information stored there.

The lock is configured via a configuration device which transmits the data to the lock via the BLE radio standard or wired via RS-485.

A piezo buzzer is integrated to signal the statuses and warnings. Additional optical displays are provided by the Outside module.

The HSL 103 also has an interface to a slave lock (e.g.: food hatch lock).
