The Kouba Interlocking Door Control System (MT Series) will integrate with any electronic access control system including older or legacy control systems.

The MT model uses door position switches, an optional presence sensor and request to unlock signals from the access control system to monitor and control two or more interlocking doors. Only one door may be unlocked or open at the same time. The mantrap will not unlock a door if the other door is open, or if an alarm condition exists. The interlock alarm relay opens if both doors are open at the same time.

Lock output relays control the locks, display plates indicate system status to the persons using the system, and alarm relays communicate system status to the security control center.

Optional Tailgate monitoring is available to ensure that only one person enters the secured area for each valid card presented.

SYSTEM OPERATION

MANTRAP READY- The mantrap is empty, both doors are closed, no alarm condition exists, the displays indicate READY.

REQUEST TO UNLOCK - An Access Control System uses card readers or biometric readers to grant access to persons using the mantrap. The ACS generates a Request To Unlock (RTU) relay contact to the MCIO-IDC when a valid card or biometric is read. The MCIO-IDC will unlock the door associated with the reader if the other door is not unlocked or open, and no alarm condition exists.

ACCESS GRANTED – When an RTU is received and the MCIO-IDC unlocks the door, the display at the unlocked door will indicate PROCEED, and the display at the other door will indicate BUSY.

DOOR OPEN – While a door is open, the other door is locked, MCIO-IDC will not accept an RTU, and the displays indicate BUSY.

MANTRAP OCCUPIED with DOUBLE VERIFICATION PASSAGE – Card and/or Biometric readers are located on both sides of each door. A valid read must be presented at each reader and the ACS activates an RTU for every time each door is to be opened. A person has entered the mantrap, both doors are closed, the displays outside of the mantrap indicate BUSY, and the display inside the mantrap indicates READY. The person must present a card or biometric to the reader inside the mantrap. Once a valid read is presented, then the 2nd door will unlock, and the person may open the door and complete passage through the mantrap. If the person does not present a valid read within an adjustable time delay, then the system will activate the TOO LONG IN MANTRAP ALARM.

MANTRAP OCCUPIED with SINGLE VERIFICATION PASSAGE – Readers are located at each door outside of the mantrap. Only one valid read is required to pass through the mantrap. The person presents a valid read at the 1st door, the ACS generates an RTU, the MCIO-IDC unlocks the door, the person opens the door, walks into the mantrap, closes the door, and a short time after the 1st door is closed, then the 2nd door will unlock, and allow the person to complete passage through the mantrap.

SYSTEM BYPASS – The BYPASS input to the MCIO-IDC is activated. If an alarm condition exists then the alarm is reset. The doors remain locked. Any RTU presented will unlock the door associated with the reader. The doors are not interlocked, and both doors may be unlocked and/or opened at the same time.

LOCK CONTROL RELAY – DPDT relay with an integrated LED that turns on when the relay is active. The relay activates when an RTU is presented and all other interlocked doors are closed and secured, or if the RTU is presented when the system is in BYPASS.

ALARM AUTOMATIC RESET – The system automatically resets an alarm after the doors are closed and the mantrap is empty. The automatic reset feature may be disabled through the on board dip switches.

SYSTEM STATUS DISPLAYS – Single gang indicator plates with LED’s to indicate system status to persons using the mantrap are mounted adjacent to the readers. Typical indications are READY, PROCEED, & BUSY. Alternate text for the displays is available.

AUDIABLE ALARM – a sounder output relay is activated when the unit is in alarm. This output may be connected to a 12 VDC sounder to indicate an alarm at the mantrap.

ON BOARD ADJUSTMENTS AND INDICATORS– The MCIO-IDC has on board time delay adjustments, function select dip switches, and input status LED indicators, and output status indicators. The indicators show the status of all inputs and outputs, and assist during system setup, verification or service.
