HSL C103: Retrofit for CHUBB® Model 3R63
Steinbach & Vollmann presents the HSL C103, a new electromechanical high-security prison lock that stands for maximum reliability, durability and versatility. As a hybrid lock, it combines electronic control with robust mechanical locking technology and thus fulfils all the requirements of modern prisons.
The HSL C103 is designed as a high-quality mortise lock made of stainless steel and combines two independent locking methods: In electric mode, unlocking is triggered by a 24 V DC signal. As long as this signal is present, the bolt can be retracted via a handle or rotary knob - on one or both sides. After closing, the lock locks automatically via the auxiliary latch. In manual mode, the lock is unlocked using a special HSL double-bit key. Here too, the bolt is retracted via the handle, but the key cannot be removed as long as the door is open. This prevents incorrect operation and the system offers maximum reliability, even in the event of a power failure.
A special feature of the HSL C103 is the night shift locking: this is activated with a special inspection key and blocks both the electrical and mechanical unlocking. The bolt cannot then be withdrawn either by signal or with a standard HSL key - a crucial security feature for night-time or emergency situations. Night shift locking is also deactivated using the inspection key, whereby a defined sequence ensures that the handle is not accidentally unlocked.
Thanks to its modular design, the lock can be customised precisely to the requirements of any facility. There is a choice of different handle variants such as T-handle, L-handle or rotary knob, each for single or double-sided operation. A special extra is the interchangeable dead latch trigger, which prevents the deadbolt from being pushed back when the door is closed. Suitable variants are available depending on the door gap (3-7 mm or 7-12 mm). Optional key guides with insect and smoke protection are available for additional security.
The HSL C103 is also pioneering in terms of access control. The master/group key function allows a hierarchical locking structure with up to 21 subgroups, whereby access rights can be individually controlled. The mechanical locking technology with 7 tumblers can also be recoded up to nine times - without having to replace the lock or a recoding key.
In terms of resilience, the HSL C103 fulfils the highest standards: The mechanical latch has been tested for over 500,000 actuations, the magnetic contact even for over one million switching cycles. The deadbolt load can withstand axial forces of up to 12.5 kN and lateral loads of up to 50 kN. For extreme operating conditions, the lock is designed for temperatures from -40 °C to +65 °C and a relative humidity of up to 95 %.
Electromechanical control takes place via potential-free contacts, whereby the lock generates various status messages, for example for bolt position, night-time locking, unlocking or sabotage monitoring. These signals can be integrated into higher-level building management systems. The installation is also designed to be practical: The lock is 100% dimensionally compatible with the CHUBB® 3R63 and is therefore ideal for modernising (retrofitting) existing systems.
With compact dimensions (229 x 29 x 205 mm) and a weight of 4.4 kg, the lock can be used in steel or wooden doors - for doors opening to the left or right, inwards or outwards. The robust stainless steel finish ensures durability even under the toughest conditions.
