AIRLOCKS, INTERLOCKS & MANTRAP

HIGH SECURITY INTERLOCKING DOORS

High security to control entry and exit


The Borer Fusion system supports user programmable state-of-the-art door interlock/access systems for cleanrooms, containment suites, laboratories, secure areas and critical areas that need high level security access control or airlocks to safe-guard against cross contamination. The Interlock function is inbuilt into Fusion Systems and controllers so are a no cost alternative to custom built interlock controllers.

Airlocks and Interlocks

In its simplest form, a door interlock is made up of two electronically connected doors configured so that when one door is open or unlocked the associated door remains closed and locked down.  A person passing through an interlock enters the first door which must then be closed and locked before the second door is unlocked and the person permitted to complete their passage.

Door Interlocks take many forms and are used in many different applications, including:

  • Security for banking, cash rooms, data centres, archives and secure storage so as to restrict access to secure areas and their contents.
  • Security to hold people who are confined in custody suites and institutions.
  • Environment Control, maintaining a constant temperature and/or humidity in areas such as cold stores by limiting the amount of air escaping when a person opens a door to gain access or leave.
  • Clean Rooms and Laboratories used for the preparation of pharmaceuticals and the manufacture of sensitive electronic equipment. Interlocking doors help to contain the filtered air entering the clean area, maintaining a higher air pressure in the clean area stopping contaminant entering the clean area.
  • Data Centres for security and to maintain the data centre environment by preventing the escape of cooled air and the entry of dust and dirt.
  • Loading Bays to ensure that when deliveries are being made, access to warehouse areas is restricted.


Multi-door Interlocks

There is often a need for a multi-door interlock especially when a clean room or area has more than one entrance.  This requires locking down selected combinations of entrances while other entrances are in use. This is done at the hardware level with each entrance equipped with a door controller which is connected via a network cable to a Midspan Bridge. The Midspan Bridge provides a global interlock function for up to 16 doors or eight entrances with a pair of interlocking doors. A set of user generated rules running as a script in the Midspan Bridge monitors activity at each entrance, locking down selected entrances while people access other associated entrances. Users setup and modify their own interlock rules.

Summary of Key Features

  • User programmable interlock rules with support for from one portal with two interlocking door and up to eight portals with sixteen interlocking doors.
  • Interlocking only function or complex locking sequences with delayed time release for airlock/transfer hatch purge cycles.
  • Access Authentication using card, card and PIN and biometric readers.
  • Choice of local 12V DC or PoE power supply, centrally powered using Power over Ethernet (PoE) to power doors and locks or local mains-based battery backed PSU.
  • Fire alarm connection to lock release all or selected door locks.
  • Emergency Override to release all door locks.
  • Red and green traffic lights to indicate door lock status.
  • Built-in Interlocking so no extra equipment or installation effort required.
  • Audible sounder or visual strobe warning system used when no door lock fitted.
  • Central real-time reporting of interlock breaches and activity.
  • CCTV Integration to view alarms and incidents.
  • Android Tablet based Tally Board for a dynamic real time roll-call display of who is inside controlled area.


Mantrap

A mantrap or a security booth is a security device that monitors and controls two interlocking doors so that they can’t be opened simultaneously. One door can be unlocked and opened, as long as the other door is locked and closed. Between these interlocking doors is a small, secure space, which only permits one or a small number of people to be in there at any one time.

Mantraps can be used to limit the number of people permitted to enter or to be inside a specified secure zone at any one time. In high-security applications, this ensures that at any time the secure zone is either empty or has two or more people inside, and never one person on their own.

The addition of a 3D imaging camera to count the number of people inside the mantrap, and biometric readers to verify people’s identities, will ensure that everybody attempting to pass through the mantrap will have their access credentials and identity fully validated before access is granted.

Biometric verification entails writing a template representation of the cardholder’s fingerprint to their ID card. Once a match between a cardholder and their biometric fingerprint is made by the fingerprint reader, the cardholder is fully authenticated and can safely pass through checkpoints without having to undertake any further checks.

Access control booths configured as mantraps effectively separate an unsecured area from a secured area, which makes them ideal for the protection of high-value items or in security-critical applications, such as:

  • cash handling depots
  • sensitive data processing areas
  • security control rooms
  • critical research lab
  • jewellery stores
  • vaults
  • document stores and archives

Summary of Key Features

  • Supports two user classes - resident with full access entitlement and visiting who need to be escorted by a resident user.
  • Four eyes access rule ensures that area accessed via the mantrap shall either be unoccupied or have two or more resident users present at any one time.
  • Four eyes exit rule ensures that area accessed via the man-trap shall either be left unoccupied or have two or more resident users present before a resident user is permitted to leave.
  • Visitor access escort rule ensures that two or more resident users are inside the controlled area before a visiting user is granted access.
  • Visitor exit escort rule ensures that when a visitor is inside the controlled area, two or more resident users are left before a resident user is permitted to leave.
  • Identity authentication, the inclusion of biometric fingerprint matching ensures that the identity and access credentials of everyone transiting through the interlock are fully validated.
  • Fire alarm connection to lock-release all or selected door locks.
  • Emergency Override feature to release all door locks.
  • Red and green traffic lights to indicate door lock status.
  • Audible warning sounder or visual strobe indicators for access/egress events when no door lock fitted.
  • Central real-time reporting of interlock breaches and activity.
  • CCTV Integration to view alarms and incidents.
  • Android Tablet based Tally Board for a dynamic real-time roll-call display of who is inside a controlled area.
