locking & interlocking systems
|
security principles
Electronic locking systems are increasingly being used for the convenience of their operation. They avoid the need for the constant use of key and the security threats posed by having many key holders.
Our SAS are equipped with Seritz 2100 motorised locks and the electronic interlocking control system.
Seritz 2100 has been designed for ease of retrospective installation to existing doors, either single or multi-door systems with full interlocking facilities.
Seritz 2100 offers significant operating advantages, namely:
- It can accommodate misalignment between door and frame of up to 8mm. On external door applications, gusts of wind can stop locking mechanisms such as electric strikes and electro-magnets engaging.
- The motorised bolt combined with the mitred locking cip mean that the locking bolt physically pulls the door into the frame.
- As a result, door closers can be put to a much lighter setting making the door easier to open.
- It is a heavy duty locking system designed for intensive use and can easily accommodate in excess of 1000 operations per day.
- It is naturally fail-safe. With emergency power back-up, it can operate as a fail-secure lock.
operating principles
The C3S Seritz 2000 consists of 2 elements: a motorised element, which is fitted to the head of the door frame, and a receiving cup which is fitted to the opening leaf of the door.
Contacts are fitted in the motor unit and the door leaf, which, when aligned, cause the locking bolt to be drawn into the receiving cup. The action of the locking bolt retracting into the cup, the inner faces of which are mitred, physically pulls the door leaf into the frame. This assistance to the final closing means that a door closer can be set to exert less pressure to bring the door leaf back into the frame than would be needed with other types of electric locking systems. In turn, this means that doors fitted with Seritz 2000 are easier to open.
• 24v motor unit driving the locking bolt, fitted to the head of the door frame
• The locking bolt consists of 2 roller bearings to ensure minimum operating wear. It is robust and has a locking stroke of 35mm
• Integrated circuitry allows connection to status monitoring systems, break-glass and general fire safety systems for immediate release in the event of a fire
• Mitred locking-bolt receiver fitted to the opening leaf of the door
• Electromagnetic element ensuring "Fail-safe" operation
• Left or right hand operation
emergency unlocking
Seritz 2000 is fitted with an electromagnetic element which enables automatic release in the event of emergency exit being required. The power supply to the electromagnet is interrupted which immediately causes the locking bolt to separate from the motor element and, being linked to a spring-loaded mechanism, throws the locking bolt out of the cup enabling the door to open.
The interruption to the power supply is by operation of the Break-Glass or
other similar mechanism.
N.B. A back-up power supply ensures that security is maintained in the
event of power failure. |
