Door Interlock Systems
Door Interlock System (DIS)
Product Description:
The Door Interlock System (DIS) prevents more than one door from opening at the same time, under normal conditions. The Door Interlock System is electrically operated using magnetic locks and magnetic door switches. Pushbuttons installed at the doors are for overriding the magnetic locks in the event of an emergency. Visual and audible alarms sound when a door is opened and will silence upon closing. This system is designed to meet recommended and/or mandatory requirements for maintaining containment levels based upon standards of the below governing organizations:
- National Institutes of Health (NIH) Design Requirements Manual for Biomedical Laboratories
- Laboratory Biosafety Guidelines of Canada
- World Health Organization (WHO) Laboratory Biosafety Manual
The Door Interlock System can be used in many applications for environmental and safety control such as laboratories and clean rooms where airlocks are utilized, darkrooms, x-ray and other treatment rooms, and more, for example.
Note: If this system is installed in an animal laboratory (ABSL), the audible alarm can be easily disconnected to not disturb the animals.
The flush control panel comes with a stainless steel flush cover and 12”H x 12”W x 4”D steel back box. The surface control panel comes with a hinged non-detachable cover from the 12”H x 12”W x 4”D surface box. The surface box with cover is made of steel with a baked enamel gray coating.
The Door Interlock System can be included as a kit containing a control panel with optional devices, such as: door magnetic locks, magnetic door switches and door emergency release pushbuttons mounted in stainless steel wall plates for a two, three or four door application. Control panels and pushbuttons are available in flush or surface models. The pushbuttons for a kit will be provided as flush or surface determined from the control panel selection.

Intelligent Door Interlock System (iDIS)
Product Description:
The intelligent Door Interlock System (iDIS) prevents more than one door from opening at the same time, under normal conditions. The Door Interlock System is electrically operated using magnetic locks and magnetic door switches. Push-buttons installed at the doors are for overriding the magnetic locks in the event of an emergency. Visual and audible alarms sound when a door is opened and will silence upon closing. This system is designed to meet recommended and/or mandatory requirements for maintaining containment levels based upon standards of the below governing organizations:
- National Institutes of Health (NIH) Design Requirements Manual for Biomedical Laboratories
- Laboratory Biosafety Guidelines of Canada
- World Health Organization (WHO) Laboratory Biosafety Manual
The iDIS can be used in many applications for environmental and safety control such as laboratories and clean rooms where airlocks are utilized. There are also other applications that the iDIS door interlock system could be used such as: darkrooms, x-ray and other treatment rooms, and more, for example.
The iDIS is an intelligent, multi-mode door interlock system.
The flush control panel comes with a stainless steel flush cover and 12”H x 12”W x 4”D steel back box. The surface control panel comes with a hinged non-detachable cover from the 12”H x 12”W x 4”D surface box. The surface box with cover is made of steel with a baked enamel gray coating.
The iDIS control panel can be provided with optional devices, such as: door magnetic locks, magnetic door switches and door emergency release push-buttons mounted in stainless steel wall plates for up to three groups and seven doors. Remote Stations can also be provided with each group of doors.
Let’s explain the model number by using this example of iDIS-20119-X-X-X-X. The iDIS-20119 part of the model number will be the same on all model numbers. The first ‘X’ is for the mode or groups of doors, the second ‘X’ is for the total quantity of doors in all groups, and the third ‘X’ is for the quantity of Remote Stations determined by the quantity of groups.
There are four modes with different groups or sets of doors in each mode. A Remote Station is needed for each group of doors.
- Mode 1: There are two (2) groups or sets of three (3) doors. This mode can operate three (3) doors in two (2) different locations. This would be a total of six (6) doors and two Remote Stations.
- Mode 2: There are three (3) groups or sets of two (2) doors. This mode can operate two (2) doors in three (3) different locations. This would be a total of six (6) doors and three (3) Remote Stations.
- Mode 3: There is one (1) group or set of four (4) doors and one (1) group or set of two (2) doors. This mode can operate four (4) doors in one location and two (2) doors in another location. This would be a total of six (6) doors and two (2) Remote Stations.
- Mode 4: There is one (1) group or set of four (4) doors and one (1) group or set of three (3) doors. This mode can operate four (4) doors in one location and three (3) doors in another location. This would be a total of seven (7) doors and two (2) Remote Stations.
Flush
The flush main control panel comes with a stainless steel flush cover and a 12”H x 12”W x 4”D steel back box. The Push Buttons for Emergency Release will come mounted on a single-gang stainless steel cover plate for flush mounting. The Remote Stations with indicator lights and sounder will come mounted on a single-gang stainless steel cover plate for flush mounting. If you desire flush mounting for your application, select ‘F’ when building your iDIS model number.
Surface
The surface main control panel comes with a hinged non-detachable cover permanently attached to a 12”H x 12”W x 4”D surface box. The surface box with cover is made of steel with a baked enamel gray coating. The Push Buttons for Emergency Release will come mounted on a single-gang stainless steel cover plate for surface mounting on a surface box provided by others. The Remote Stations with indicator lights and sounder will come mounted on a single-gang stainless steel cover plate for surface mounting on a surface box provided by others. If you desire surface mounting for your application, Select ’S’ when building your iDIS model number.
